c-BMSTM
Description
The c-BMS24 offers compact battery management for up to 24 cells connected in series for up to an approx. 100V max pack voltage depending on cell chemistry.
Despite measuring only 150 x 70 mm, the c-BMS24 is equipped with a powerful dual core processor and state of the art application specific integrated circuit (ASIC), can reach temperature accuracy of ±1 °C and high SOC accuracy.
The c-BMS24 can be configured via the licensed c-BMS CREATOR software. This tool allows battery integrators to create application-specific settings, optimizing battery performance and life.
