CSC

CSC
Battery Management

Depending on the cell technology, up to 300 lithium-ion cells are interconnected in series. Overvoltage and undervoltage, communication faults or interrupted lines to individual cells indicate safety-critical conditions in the battery system.

TECHNOLOGIES
The CSC (Cell Sensor Circuit) monitors the individual cells of the battery through the measurement of voltage, temperature and SOC. Every CSC is equipped with a passive discharge path in order to balance out the battery cell charges. The cell sensor circuit communicates with the superordinate BMS.
