The voltage of every battery module in series connected battery pack is important for diagnosing the battery pack, estimating the state of charge (SOC) of the pack and equalizing the pack in the battery management system (BMS). This paper introduces a method based CPLD for measuring the voltage of the battery module in series connected battery pack. The design and realization is also presented in detail. This method is already used successfully in BMS for EV and HEV.
