High Voltage Battery Control System

Description

The high voltage battery system consists of the BMS ECU (Battery Management System ECU), Power Relay Assembly (PRA), safety plug, battery temperature sensor, and battery ambient sensor. Especially the BMS ECU controls SOC (State Of Charge), power, cell balancing, cooling and troubleshooting of the high voltage battery system.
The PRA includes main relays (positive, negative), pre-charge relay, pre-charge resistor and battery current sensor.
