HVBMS Battery Junction Box (BJB)

HVBMS-BJB

The battery junction box (BJB) is the controlling part of the BMS. It measures several high-voltages throughout the overal BMS, accurately and redundantly measures the system's current and measures isolation resistance between the battery and the chassis for isolation monitoring.
