Battery Management

The BMS contains three processors for maximum reliability and safety. It collects all the information from the sensor modules, the cell sensor circuits and the power measurement board, calculates the battery system status and controls the HV contactor.

TECHNOLOGIES
The BMS (Battery Main Supervisor) is the central control unit of the battery system. It is connected with the CAN vehicle architecture and ensures the safety of the entire battery system. Over and above this, the BMS provides the required condition determination and performance prediction.
