A scalable kit for high voltage battery management and safety monitoring
Overview
The STW.csc (Cell Sensor Circuit) monitors the individual cells of the battery through the measurement of voltage, temperature and SOC. Every STW.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.
