Grid Storage Battery Testing

Similar to electric vehicles (EVs), the massive energy storage systems required for grid-scale applications need to operate for an extended 10+ years of life and withstand many thousands of cycles. Arbin provides battery test equipment for cells, strings/modules, and packs of all sizes to meet the demands of stationary storage applications ranging up to 1MW in power.

Energy Storage Systems and the Power Grid

Reliable energy storage systems benefit the power grid by supplementing peak capacity requirements and the use of micro-grids or distributed energy storage. Grid storage system operators must ensure that the grid has enough energy to meet demand during peak times. A battery energy storage system (BESS) that collects energy and releases it as needed can serve as a backup during peak usage. This eliminates the need to increase overall energy generation capacity to accommodate extreme demand.

Distributed energy storage allows smaller, more efficient power distribution networks at a local scale using microgrids. These microgrids can function autonomously or as part of a larger power grid system. They require sources of energy generation (typically renewables like solar and wind) and large battery packs to store the energy. Distributed energy storage systems:

Provide support for renewable energy generation
Allow frequency regulation and improve power quality
Load shifting so power can be stored when costs are low and discharged when costs are higher
Provide backup power during outages.

Battery Testing for Grid Storage Applications

Batteries are the critical component in energy storage systems that determine performance under specific operating conditions. It is important for batteries to provide enough energy for the load, temperature conditions, and duration they will experience during their useful life. Battery manufacturers provide general specifications for their cell or module performance, but these need to be evaluated in combination with application-specific parameters.

Typical performance indicators will include discharge performance under various conditions, peak discharge current, internal resistance, endurance cycling, energy efficiency metrics, and more. These metrics will serve as a baseline performance comparison for different types of batteries being evaluated for a grid storage system.

Regenerative (Back-to-Grid) Testing

Arbin users state-of-the-art regenerative circuitry for all high-voltage/high-power applications. Energy storage systems for grid-scale applications commonly need to be tested at 100s of kW. Arbin’s regenerative “RBT” test equipment provides a range of 2.5kW to 1MW of power. High-efficiency circuitry and power density minimize the cost of operation compared to similar equipment.

Thermal Safety and Arbin’s Battery Test Equipment

Thermal safety is a key factor that can affect battery stability and safety. Grid storage systems are often located outdoors and are thus exposed to the elements and changes in weather and ambient temperature. Arbin has created an innovative new temperature chamber for testing individual cells known as the “MZTC” Multi-Chamber.

이 셀 분리형 배터리 테스트 챔버는 각 셀 또는 셀 쌍(셀 크기 및 암페어에 따라 다름)을 분리하여 보다 안전한 테스트 환경을 조성하고 온도 안정성을 유지합니다. 8개의 미니 챔버 각각은 고유한 온도 설정값을 제공하며 열 폭주 또는 연쇄적인 고장 이벤트를 방지하기 위해 다른 챔버와 열적으로 격리되어 있습니다. 또한 Arbin의 MZTC 배터리 테스트 챔버는 셀을 쉽게 연결하고 인터페이싱할 수 있습니다.

Arbin also has the option to interface with a variety of third-party temperature chambers from other manufacturers. The software is compatible with most major chamber controller models around the world, so the Arbin tester can automatically turn the chamber on and off, and adjust the temperature during the test.

Grid energy storage systems will become more and more widely adopted when the safety of the system can be assured. Battery test equipment must help determine the parameters within which batteries can operate safely while also maintaining a safe test environment.
