Battery Management Systems

No lithium-ion battery comes without a Battery Management System. Why? Because the multilevel electronic system ensures safety, extends the battery’s lifespan and improves its performance. To do this, it measures every battery parameter, breaks the circuit if necessary and optimizes capacity usage during charging and discharging.


The BMS kit provides an ideal basis for prototype construction and the production of small series. Together with cell monitoring modules, the kit maps all battery management and safety functions. The BMS modular system is the development basis for tailor-made battery management systems on an industrial scale.
