Supercap Voltage up to 100V
Supercap Current up to 2500A
A variety of standard solutions are available as well as customized systems.
Arbin offers supercap testing systems for basic charge/discharge cycling, and simulating complex real-world applications such as drive profiles, telecomm pulses, or other custom profiles.
Arbin’s LBT product series commercializes technology established during a 3‐year ARPA E project developing ultra‐high precision testing systems. This product consists of independent potentiostat/galvanostat channels for testing batteries and other electrochemical devices, and is intended to provide an economical solution for applications requiring high‐precision measurements and fast data sampling. All Arbin testing systems come with a PC preloaded with our MITS 7 and Data Watcher software for creating test profiles, real‐time data monitoring, and data plotting & analysis.

- A wide array of auxiliary inputs/outputs are available for additional data collection or control such as temperature monitoring, additional reference electrodes, and more
- Multiple levels of fusing are provided inside the system for protection as the channel/board and power supply levels.
- Each channel module has a fully redundant microcontroller dedicated for safety monitoring.
- Arbin’s software has safety functions for entire tests, and for individual steps within a test to help the user avoid overcharging, over‐discharging, over‐heating, etc.
- Tests begin with a built‐in safety check of all control values.
Arbin Instruments provides a wide variety of auxiliary modules for expanding the capability of the main charge/discharge control circuitry. Modules can either be placed in the main chassis, or in a small external chassis. This also makes it easy to add auxiliary options to existing systems.
Auxiliary Voltage – Used as additional reference electrodes to measure voltage.
Temperature Thermocouple/Thermistor – Used to record temperature as well as control the test schedule
MTCI (Chamber Interface) – Interface with a 3rd party temperature chamber so Arbin software can turn chamber on/off and adjust temperature
Digital I/O – Send and receive a simple on/off signal to interact with external devices.
Analog I/O – Control any device operating on a 0(2)‐10V signal.
CANBus – Communicate with internal pack circuitry using CANBus protocols.
UPS – Uninterrupted power supply for PC so tests can resume automatically after brief power outages.
Battery Connections – A variety of battery holders are available for cylindrical cells, flat/pouch cells, and more.
RSMS – Fully redundant safety monitoring systems that can disconnect the device being tested in case of failure.
Shunt – high-precision shunt may be used for calibration of your Arbin system.

Importance of Precision
This plot illustrates the difference between Arbin and another leading manufacturer. The two distinct dips in the plot may have been missed using an inferior tester. While many companies try to sell the same antiquated equipment for over a decade, Arbin has been hard at work improving our designs to meet future industry demands. We learned a lot during our three year ARPA-E project and have implemented this new technology in our LBT and HPT product series. The HPT systems represent our premium product, but LBT is superior to all other standard testers on the market.
Please see our HPT Product Series to learn more.
What Affects Tester Precision
Arbin Tester Improvements
Measurement precision is more critical for long‐term testing and long‐term projections than control accuracy alone. Most other battery testing systems do not correctly specify their precision and/or have relatively poor precision, which hinder the conclusions drawn from results data. Important trends and electrochemical indicators may remain unnoticed; lost in the measurement noise as illustrated above.
Our hope is that these higher degrees of measurement precision will lead to new discoveries and characterization metrics across the energy storage industry for all organizations, not only those looking at coulombic efficiency as a key indicator.
