In 2019, the European Commission presented an ambitious strategy for sustainability - the European Green Deal, which aspires to make Europe the first climate-neutral continent by the year 2050. Along with restoring a healthy environment, the goals of this extensive plan include protecting wildlife and generating new economic opportunities. The Green Deal is composed of a series of sustainability milestones across industries as varied as agriculture, textiles, construction, and transportation, as well as energy.

An Increased Demand for Sustainable, Clean Energy Solutions

Better energy solutions are a key aspect of the Green Deal. Its initiatives seek to establish a reliable and affordable energy supply, build a fully integrated EU (European Union) energy market, and prioritize overall energy efficiency. With energy production and use accounting for most of Europe’s greenhouse gas emissions, the transition to renewable, efficient energy sources is a critical part of the European Green Deal.

In particular, the European Green Deal highlights the need to reduce CO2 emissions. Transportation represents a sizable portion of this problem, as up to 25% of the EU’s greenhouse gas emissions result from transportation. To further speed up the adoption of electric vehicles (EVs), which boast zero emissions, the EU has proposed a ban on new fossil-fuel cars from 2035.

These Green Deal initiatives compound the pressure of heightened public interest in environmental concerns and a growing demand for EVs. The increased emphasis on sustainable energy systems means an even greater demand for the research and production facilities that support the electric vehicle industry and other renewable energy solutions.

The Rise of the Gigafactory in Europe

One solution to this growing need is the introduction and propagation of gigafactories. As indicated by their name, these production facilities dwarf the size of typical factories and are designed to meet massive research and production needs. Tesla, whose CEO is credited with the invention of the term “gigafactory,” started construction on the very first one in June 2014 near Sparks, Nevada. At only 30% complete, the facility has 5.3 million square feet of operational space and is intended to supply lithium-ion batteries for a planned production of 500,000 cars per year.

Other gigafactory projects have followed, looking to address the current and anticipated demand for EVs and other sustainable energy solutions – particularly in Europe. As part of its mission to develop the world’s greenest battery cell, Northvolt established the battery gigafactory Northvolt Ett in Sweden. In Berlin, Germany, Tesla plans to complete its first Europe-based gigafactory this year, which will manufacture both battery cells and vehicles.

These two macro factories are just the beginning of gigafactory development in the countries of Europe. More than 20 European gigafactory projects are planned for completion over the next few years, with a focus on battery cell technology. As planned, these facilities would provide more than 1,000 GWh (gigawatt hours) of battery capacity by 2030, staying ahead of the anticipated demand based on current policy. Acceleration of standards in the coming years would bring these demand and capability figures even closer. Even with their massive production capabilities, by 2040, these gigafactories may fall short of the projected EV battery demand for Europe.

Arbin’s Response to the Needs of Gigafactories

As part of our aim to support those moving the battery industry forward, Arbin Instruments is committed to battery development in Europe. Arbin is working to address the increasing demand for battery research and production in two key ways: cycler and data management solutions for larger operations and a dedicated, growing Arbin Europe team.

Production facilities the size of the latest gigafactories require efficient management of both battery test equipment and the results data that testing produces. Arbin’s Central Monitor and Control Solution (CMCS) allows for control of multiple battery testers from a single PC, including the ability to start, stop, and resume testing. The CTI (Console TCP Interface) Interface also allows for third-party control of Arbin battery test equipment. For data management, our Central Data Solution (CDS) offers the ability to backup data to a central network or cloud-based server for use in dedicated analysis programs.

Our dedicated Arbin Europe office is also positioned to help meet the continent’s increasing energy research needs.

Arbin CAN: BMS-to-Tester Communication with Arbin’s CAN Bus Capability

March 10, 2022

Testing the Battery Management System (BMS) for a battery pack is a critical element in the battery validation process. Used to monitor the individual cells in a battery pack, the BMS can communicate essential information to an external interface, such as the battery test equipment. This BMS-to-tester communication has several important functions including verifying the BMS is functioning properly by comparing the BMS readings to the tester measurements. The Arbin CAN interface also allows the BMS to control the tester in real-time and apply dynamic “clamp” limits that can protect or further enhance the testing process. To take advantage of these features, however, the Battery Management System needs a communication protocol.

CAN bus is the most common protocol for communication between a cycler and a BMS. It provides a wide range of communication and control capabilities. Arbin’s Mits Pro employs the CAN Bus protocol, allowing CAN messages to be sent and received between the battery test equipment and the Battery Management System, and allows external control of the Arbin tester.

The Advantages of Arbin’s CAN Bus Capability

Arbin’s CAN Bus interface feature offers several important benefits for battery test operators. First, it provides you with a more flexible solution for CAN communication. Versatile enough to address a wide variety of testing applications and profiles, Arbin’s CAN Bus features can be used without third-party equipment, DLL packages, or licenses that are typically required. Through Mits Pro, Arbin’s CAN Bus functionality also allows you to define your own protocols, assign nicknames, and control tests according to your specific needs and testing standards.

Dynamic control of the Arbin cycler is another benefit of this CAN Bus feature. Unlike standard solutions, control of testing with Arbin’s CAN Bus feature is not restricted to static values for the length of the test. You can assign a CAN message to control values dynamically, with different values at various stages of a test. The CAN Bus solution also allows the BMS to fully control the Arbin testers’ charge and discharge using the CAN protocol.

The final key advantage of Arbin’s CAN Bus solution is that it facilitates communication and control between the Arbin battery tester and the Battery Management System in four distinct ways. You can customize the CAN configuration to fit virtually any requirements, allow the BMS to fully control the test equipment, monitor CAN information, and export CAN and I/V data to CSV or Excel formats for reports.

1. CAN Define: Customize Your CAN Configuration

Arbin’s CAN interface allows users to easily import their dbc file with custom CAN protocols. Once imported into Arbin’s GUI the CAN dbc is fully customizable to edit, add nicknames to CAN IDs, units can be assigned to IDs, and each can be enabled or disabled for control and logging during the test. No additional 3rd party software, licenses, or DLL packages are required for this level of convenience. A unique CAN configuration file can be assigned to each test channel on the Arbin tester.

Import and Customize CAN Configuration Protocols

The ease of import and customization to work with the CAN IDs is the foundation of other powerful abilities of Arbin’s CAN Interface. Arbin supports sufficient CAN Message IDs to allow the use of extra sets of protocols. As a result, the tester can communicate with the BMS as well as other external sources at the same time.

2. CAN Control: Fully Control the Arbin Battery Tester

Arbin’s CAN Bus capability also offers the ability to fully control your battery test equipment. This includes several key features, such as read/write integration, dynamic upper and lower “clamp” limits, and external control of the tester.

Read/write integration with the Battery Management System through CAN Bus allows for full control of the cycler’s charge and discharge. The “Write CAN Message” option can be used to send a command or multiple commands to the BMS throughout a test procedure. Through CAN messages, the BMS can tell the test equipment to charge or discharge at a particular value of current, power, etc. Including dynamic control. This communication can also be used to tell the test equipment to discontinue or slow down the charge or discharge at a certain value.

Use the "Write CAN Message" Option to Send Commands to the BMS or Third-Party Software

Dynamic upper and lower “clamp” limits are another important CAN Bus feature enabled through CAN messages. You can set CAN meta-variables that assign dynamic power and current limits in real-time while a test is running, rather than a single static limit that is pre-defined in the test schedule.

These dynamic limits help to increase the safety of the system during testing and validate BMS protection of the battery. For example, the BMS can limit the power during a simulation based on the dynamic limit, even when the simulation profile calls for a higher power and/or current level. The dynamic power and current limits are especially important for drive cycle simulations and similar testing applications so the simulation can run without pausing, but the BMS can limit the peak power output of the simulation.

CAN communication also allows for external control of the Arbin battery tester. An external source such as LabView can send CAN messages to control the test equipment. You can also employ the “Write CAN Message” option to send a command to third-party software throughout a test, just as you can through the Battery Management System. This is especially powerful during BMS development.

CAN Monitor: Monitor CAN Information

Another important feature of CAN is the ability to actively monitor CAN information. The Monitor and Control interface of Arbin’s Mits Pro software lets you monitor CAN details in real-time so that you can see communication and changes as they happen. Additionally, the Monitor and Control interface provides tools to send CAN messages manually.

Monitor CAN Information Through the Monitor and Control Window

On top of monitoring real-time information, the data monitoring highlights of CAN include generating reports to compare testing data. With this feature, you can conveniently cross-reference the data collected by your battery testing equipment with the data from the Battery Management System in a single results file. Having this data in one location makes it easier to compare and analyze the results.

4. CAN View Data: View and Export CAN and I/V Data

Finally, Arbin’s CAN Bus features include export options that give you even more flexibility review, store, and analyze your testing data. You can easily export both CAN and I/V data in either CSV or Excel formats with this capability. The CSV and Excel formats allow you to import your data to third-party programs for more advanced processing.

Using CAN Bus Communication for Power Clamp Limits

One use case for Arbin’s CAN Bus features in simulation profiles is through power clamp limits. With traditional termination limits, surpassing the limit in an EV (Electric Vehicle) drive profile, for example, means that the test is stopped, halting your testing progress. In addition, the simulation profile will have to be changed manually, to address the battery operating parameters that caused the battery to exceed those safety limits.

Although standard safety limits are still implemented along with the CAN option, CAN Bus communication offers an additional layer of flexibility. CAN protocol can assign a “power clamp” limit that is controlled dynamically over the course of the test. In this case, the BMS or modeling program will send messages that update the power output limit throughout the test.

Dynamic Upper and Lower "Clamp" Limits Using CAN Message IDs

Unlike traditional safety limits, the power clamp limit restricts the power output of the Arbin system without stopping the test. With values that are dynamic over the course of the test, this can better reflect real-life conditions and power output. Using CAN Bus communication to set power clamp limits will not only expedite the testing process, but will also allow for more complex control of the power output limits.

Arbin’s CAN Bus Capabilities and Your Customized Testing System

Arbin’s CAN Bus feature allows for communication between a BMS and an Arbin battery tester, something that is critical for many testing applications. Protecting the system and battery and actively controlling test equipment through the Battery Management System are just a few of the benefits from CAN communication.

These CAN Bus capabilities are just one of many features Arbin offers to give you the tools you need to address your specific battery testing requirements. Contact us today to learn more about using CAN with your BMS and your Arbin battery testing equipment – and more features to customize your testing setup.

What is to Come in Battery Technology

November 24, 2021

Battery technology is ever evolving as research and development into different materials, configurations, and designs bring new insights and breakthroughs. As the world moves towards green energy, batteries play an important role in powering the future. Be it consumer devices like smartphones or laptops, or electric vehicles and grid storage, battery technology is essential.

It can be years from when a breakthrough is made until it becomes commercially viable. During the period of maturing, more discoveries could potentially change the game. Arbin Instruments has been a long-standing participant in battery research, providing high quality, high precision battery test equipment to support research and development in various ways. Here are three technologies that could make an impact on the future of battery performance.

Maturing solid-state batteries

Solid-state batteries (SSB) have been in the game for a while. The appeal of this technology is that it replaces the flammable liquid electrolyte within current batteries with a solid alternative, mitigating the fire risk. However, over the years there have been many obstacles to overcome in order to design a viable version of the battery. These include issues like interface between electrodes and electrode degradation. Because of its solid form, ions within an SSB cannot move as freely between the anode and cathode as within its liquid counterpart, and they tend to degrade too rapidly for long cycle life applications.

These issues are gradually being addressed. Sakuu Corporation recently announced an industrial 3D printer that could mass produce solid-state batteries for smaller electric vehicles, technology that can be easily scaled up for larger applications. This simplifies the manufacturing process and lowers costs of SSBs, and could be applied to existing or new materials.

Other companies have also been exploring ways to deliver more seamless ways to transition to solid-state alternatives. Natrion, a battery research startup, recently announced a high-performance, flexible, and durable solid electrolyte film. The company designed the component in a way that is easily compatible with current lithium-ion battery manufacturing processes, so that manufacturers can rapidly transition their production lines into adopting this technology, without changing the entire process. This also helps to lower production costs and reduces concerns around complete revamps of production lines.

Non-lithium batteries

There are a multitude of material and chemical combinations that can comprise batteries. Different configurations change the efficiency, capacity, and stability of a battery. Most common batteries nowadays use lithium, with nickel, cobalt, and manganese among others to make up different battery components. Many researchers are investigating materials like air or silicon that can be combined with lithium removing more toxic metals like cobalt from the battery.

However, there is also research into batteries that do not use lithium. One such example is a CO2 battery. Startup company Noon Energy has been exploring a low-cost rechargeable battery that uses carbon and oxygen and is eyeing this as a solution for grid-scale storage. As renewable energy is adopted more and more, larger and more efficient storage solutions need to be developed to ensure a reliable amount of energy is stored for use. They favor the use of CO2 as it is abundant, cheap, and energy efficient.

How Arbin can support battery research

Arbin continuously innovates to support battery research. For instance, Arbin commercialized a three-electrode “3E” coin cell design developed and patented by General Motors. The extra reference electrode allows researchers to evaluate both the positive and negative electrodes simultaneously during cell testing. This helps to reduce time and cost during the research process.

The Arbin multichannel potentiostat/galvanostat system (MSTAT) provides independent potentiostat/galvanostat channels that each have a built-in connection for such three electrode cells, and supports both coin cell and pouch formats. The accompanying “3E” cell holders can be plugged directly into the MSTAT channels for testing.

The MSTAT can be used with a wide range of battery chemistries and provides best in class performance with 24-bit resolution and precision better than 40ppm. Arbin can help researchers identify which electrode in the battery is the limiting factor faster than ever before!

Various modules that can be added onto Arbin systems can also support battery testing and materials research. The EIS module is an integrated solution that combines the battery test performance of Arbin with the advanced EIS capability of Gamry, allowing users to share up to 32 Arbin tester channels with a single Gamry EIS unit.

Innovation is an ecosystem. Advances in battery test equipment and tools help lead to new findings and expediting the R&D process. High quality battery testing technology can support materials research in order to explore new chemistries that could lead to the next generation of high-density energy storage devices. Although the process of research and development can be long and arduous, there are many breakthroughs big and small happening all the time. All these, together, lay the foundation for the technology and world that we will experience in the near future.

The Impact of Temperature on Battery Testing

November 12, 2021

Temperature has a significant impact on battery performance. A battery releases energy through electro-chemical reactions and these reactions are encouraged by higher ambient temperatures. Different battery chemistries have different ranges of optimal operating temperatures. Depending on the application or the climate that the battery will be used in, they would be required to operate in higher or lower temperatures.

However, operating batteries at extreme temperatures also comes with risks. At higher temperatures, there is a reduction in internal resistance, which means higher electron mobility and greater charge/discharge rates. Nevertheless, studies have also shown operating a battery at elevated temperatures speeds up degradation, diminishing the cell’s life cycle.

Continuous exposure to high temperatures can also cause unwanted chemical reactions and result in gas, corrosion, or even fires and explosions. Moreover, a battery cell can enter into thermal runaway — when the cell heats up faster than heat can dissipate, causing a continuous increase in temperature. If one cell in the pack heats up, this can quickly cause the whole pack to overheat, undermining the safety of the system, machine, or surrounding people.

Conversely, lower temperatures decrease battery performance and energy capacity. Electro-chemical reactions are not as active and the internal resistance increases, damaging the battery in the long run. This is why it is extremely crucial to take temperature into account when testing batteries.

Why is temperature important in battery testing?

Battery testers and researchers need to establish how a battery would react under different temperatures to see if they are suitable for their intended application and location of use. As new battery chemistries emerge or existing ones improve, researchers must conduct testing to determine the battery’s optimal temperature range for peak performance. Moreover, this helps determine whether it is suitable for conditions they are intended to operate in. Comprehensive testing under different temperatures also helps determine which conditions can negatively impact battery performance, and allow users to better prevent dangerous situations from occurring.

How Arbin can support temperature-controlled testing

Arbin Instruments can support labs with various products when temperature-controlled testing is needed. Arbin provides three different types of battery temperature measurement options: thermocouple, RTD, and thermistor, depending on your testing needs. Thermal sensors provide reliable temperature readings so that labs can more completely assess a battery's performance. The different sensor types are appropriate for certain ranges of temperature, with varying response times and susceptibility to electrical noise. Experts at Arbin Instruments are able to help labs evaluate the most appropriate sensor for the intended application.

How Arbin’s novel battery test chamber can help

Arbin’s novel "MZTC" Multi-Chamber is a cell-isolating thermal safety chamber with 8 independent mini temperature chambers in one benchtop unit. As each mini-chamber is its own battery test chamber, it is much easier for researchers to ensure that the temperature of the chamber is stable and uniform, significantly reducing problems from uneven temperatures that that can occur with a larger chamber. It also provides users with greater temperature control and a safe testing environment. If batteries in one chamber overheat or enter into a thermal runaway event, it is less likely to cascade to other batteries inside the other mini chambers.

Moreover, Arbin offers the “MTCI” module, an interface that is compatible with many 3rd party temperature chambers when temperature and/or humidity-controlled environments are required. Using RS232 communication, users can set the temperature of a chamber during testing. Paired with Arbin’s MITS Pro software, the user-friendly interface makes it easy for researchers to not only set the temperature of the test chamber, but also synchronize a group of channels where the temperature is adjusted only after all the channels have reached the same temperature point.

Testing equipment that can best support a battery research lab will need to facilitate both safety and productivity. At Arbin, our experts can assist in planning and recommending solutions and products that best fit your requirements.

Three Benefits of Central Battery Test System Control

September 24, 2021

Why is it important to obtain large amounts of data when testing?

Data is one of the most important elements of research and testing. In various industries and fields, data gives researchers insight into the subject of study. A wealth of data also provides a foundation upon which to base findings and conclusions. Especially in an industry such as battery testing, comprehensive and extensive testing ensures safer and more efficient batteries.

Most labs would be running more than one battery tester at a time. Testing can be a long process and researchers must make good use of time in order to facilitate battery development. Moreover, conducting large volumes of testing helps researchers to identify patterns or spot abnormalities in battery performance and testing, and address the situation as soon as possible. Without multiple tests, it would be difficult to identify the circumstances under which problems or anomalies occur. It would also be harder to pinpoint situations that need attending to.

Understanding these challenges, Arbin’s expert engineers developed the Central Monitor and Control Solution (CMCS) to complement our core MITS Pro software and aid researchers in managing multiple testers. Here we outline 3 benefits to setting up a centralized control system

1. Have all your controls in one place

A centralized control system allows researchers to control multiple battery testers from one single PC. This gives researchers a better overview and easier management of active cyclers. Users can easily see what tests are currently being conducted and schedule test times. Systems like Arbin’s CMCS allow users to start, stop, and resume testing on any networked battery testers.

2. Increase lab efficiency

Monitoring each PC, tester, or system individually can be quite inefficient and time-consuming. Centralized systems also allow researchers to control the tests without having to visit each individual machine. If anything needs to be changed or updated it can be done from one PC, saving time and energy. This leaves more room for labs to increase productivity and streamline their processes.

3. Catch problems as soon as possible

Any issues that arise during battery testing can be quite dangerous. For instance, if there is a potential for thermal runaway or a short circuit that can affect the safety of the lab, it is imperative to catch it as soon as possible. Again, if lab technicians and researchers would have to check one machine at a time it could waste valuable time. It would be easier to catch it from one central monitoring system and address any issues as soon as they arise.

Managing multiple testers and cyclers can be overwhelming. Arbin’s Central Monitor and Control Solution (CMCS) allows labs running multiple testers to better manage and monitor their ecosystem of testers. The CMCS greatly simplifies the management of battery test equipment and supports labs and researchers to conduct more productive and efficient tests. Learn more about the features of Arbin’s CMCS here.

5 Reasons Your Lab Needs a Battery Rack Connection System

July 26, 2021

As the demand for battery-powered devices rises, so does the need for battery testing. In the past, the average battery current needs were around 5-10 Amps. Nowadays, the average can be up to 100-200 Amps or even more. The added power makes it more important than ever to create a safe and orderly testing environment. One way to accomplish this is by using battery racks and connection systems.

What is a battery rack connection system?

A well-planned battery rack connection system allows researchers to set up and organize their testing equipment to optimize the safety and efficiency of the lab. The system consists of shelves that can hold the batteries undergoing testing as well as cable management. Here we outline five key reasons a battery testing lab can benefit greatly from a battery rack connection system.

1. Provide a Safe Laboratory Environment

A battery rack not only provides a definitive space for batteries to be stored, but it also allows for better cable management, and together they help prevent tripping hazards and potential dangers.

With a designated space for batteries, it will be easier to keep them out of contact with conductive materials, water, seawater, strong oxidizers, and strong acids as well as other materials that could pose a safety hazard if in contact with batteries. Moreover, it also reduces the risk of physical battery damage from being dropped, falling, or being accidentally knocked over.

Batteries like Li-ion ones have the potential to start fires if misused. Proper storage ensures that the batteries do not sustain physical damage through mishandling. It also allows researchers to easily catch when batteries are damaged or puffed up by giving them a clear and organized overview of the batteries.

With better cable management, it is also easier to identify another potential fire hazard: poor electrical connections. As cables are not left on the floor or hanging between surfaces or machines, the chances of tripping in the lab and accidentally loosening connections or damaging wires could be greatly reduced. Tripping is a common cause of accidents in a lab and can be easily prevented with proper management.

2. Comply with Laboratory Safety Regulations

Safety regulations are put in place for any laboratory setup in order to better prevent avoidable accidents. Many popular cells and other batteries formats used in research are considered hazardous materials. Since batteries are also a fire hazard and may contain toxic chemicals, proper handling and lab safety is critical.

There are several standards in place to ensure that batteries and battery testing are both safe. For instance, the Lithium-Ion Batteries Hazard and Use Assessment outlines the standards set by international institutions such as the Underwriters Laboratories, the Institute of Electrical and Electronics Engineers, and the International Electrotechnical Commission. These standards are in place to ensure consumer safety and to reduce fire and failure risks. A battery rack can assist labs in conducting efficient testing with safe processes.

A well-organized lab can also demonstrate a lab’s competence and professionalism. By meeting battery and battery test standards, a lab shows its commitment to accurate and safe testing. This helps to prove reliability and credibility to a lab’s partners, customers, and investors.

3. Simplify Physical Battery Management

As previously mentioned, battery racks help researchers keep better track of batteries as well as their respective connections. Batteries can be organized by tray or by rack and can be easily labeled by channel and position. During testing, researchers can better tie physical batteries to the data collected or to specific events. When any anomalies or testing issues arise, the relevant battery can be easily found and necessary steps taken before anything happens.

4. Use Limited Laboratory Space Efficiently

Labs are full of different equipment, computers, cables, and more. Moreover, researchers would also need sufficient space to safely navigate through the lab and reach certain equipment. Battery racks keep batteries organized, and by stacking upwards, there is more space in the lab for movement or even for extra equipment. An organization system helps keep researchers' workspace clean and tidy, in turn creating a safer working environment. Racks also make it easier to store batteries in a dry, temperature-controlled space that is required for the safe storage of batteries.

5. Enable Greater Battery Testing Productivity

With organized and efficient storage, less time can be spent dealing with various issues. Battery racks reduce potential safety issues and potential hazards from damaged batteries. Batteries that show unexpected or concerning results can be identified and removed quickly. Less time can also be spent working around batteries that are stored randomly or moving batteries when more space is needed.

A lab’s working procedures will also be more efficient and streamlined with better storage. As batteries can be stored on trays, they can be easily removed and switched out once testing is complete. Organized cables will make it more efficient to run and manage the testing process. Batteries can also be easily moved to different locations as needed for different test requirements. All these together reduce the time needed to manage the testing procedures, allowing more time for productive research.

How Arbin’s Systems Support Real Life Battery Simulations

May 31, 2021

Arbin Drive Cycle Simulation Results

Why are real-life simulations important?

Most devices do not consume energy at a constant rate throughout the day. Large applications such as electric vehicles and grid storage go through periods of high and low energy demand. Even portable devices such as smartphones or laptops may be more heavily used at certain times of the day. How something is used – charged and discharged – has an effect on the overall health of a battery. By testing a battery with a simulation that mimics how a device is used in real life, manufacturers can more accurately estimate the performance of a consumer product battery over time and identify the areas that need improvement.

What features can support accurate simulations?

Good battery testing equipment with features that can support accurate simulations can go a long way. Arbin’s Regenerative Battery Testing Series (RBT) is optimized for dynamic test profiles. Here are a few key features that can support this:

-Data Points

The RBT can support over 300,000 data points for one simulation, allowing testers to plot an intricate and nuanced simulation that better reflects real-life battery usage. This can be done without any complicated programming, as test files can be uploaded in Excel or CSV formats.

-True Bipolar Circuitry

True bipolar circuitry means that the test equipment can switch between charging and discharging with no switch time in between. With this feature, dynamic test profiles can be accurately performed and properly mimic real usage. Moreover, the interval between data points can be as low as 50ms, giving testers a wide range of flexibility in their test profiles.

-Fast Data Sampling

The presence of integrated microcontrollers allows for fast data sampling at 0.3ms. Data is logged at 5ms intervals or 2000 points per second, meaning that the system can log every little detail of the charge and discharge simulation, giving testers an accurate snapshot of battery performance.

-High-Resolution Equipment

As with all of Arbin’s equipment, the RBT series has high resolution at 24-bit, compared with the industry standard of 16-bit. This means that even the smallest change in current or voltage is visible to a greater number of digits, catching even the smallest patterns or deviations in a battery’s performance.

On top of all of the aforementioned features, Arbin’s RBT is equipped with high-efficiency circuitry and power density. With regenerative circuitry, power is sent back to the grid when discharging, which lowers the energy costs of running the testing equipment. The RBT has a regenerative efficiency of 90-92%, providing testers with a more environmentally-friendly and cost-effective battery testing solution.
