6 FAQs about [Battery stack test system]

What is battery management system testing?

Choochart choochaikupt/iStock/Getty Images Plus Battery management system (BMS) testing is the process of evaluating the performance of a BMS for a battery energy storage system. The testing process involves simulating various operating conditions and assessing the BMS’ ability to maintain a safe and efficient battery operation.

Why is safety testing important in a battery management system?

Safety testing can ensure that a BMS can reliably control safety parameters within safe limits. A BMS also regulates performance and reliability. Therefore, it is also necessary to evaluate the BMS’s ability to maintain the battery’s performance and capacity over time.

Can a battery stack have identical cells?

Battery manufacturers attempt to provide stacks with identical cells, but this is not physically possible. Even small differences lead to different charge or discharge levels, with the weakest cell in the stack disproportionately affecting overall stack performance.

How do I use the wireflow battery stack monitoring modules?

To use WireFlow's battery stack monitoring modules, connect the compactRIO directly to the cells in the battery stack to monitor the voltage of each cell and control the discharge function for each cell to create cell balancing. There are also other modules available for temperature sensors, current measurement, and CAN communication.

What is a 12-cell battery stack module?

A 12-cell battery stack module with active balancing. Electrification is the key for lower emission vehicles, but requires a smart management of the energy source—the Li-Ion battery. If not managed properly, a battery pack can become unreliable, and drastically reduce the safety of the automobile.
