■ High voltage battery 

■ The high-voltage battery is mounted in the trunk room at DC 270V with a lithiu ion polymer battery.

■ The BMS receives the voltage of each cell, the total charge and discharge current and the temperature

    value, the SOC calculated in the BMS is sent to the HCU, and the HCU controls the high voltage

    battery with reference to this value. 

■ The PRA (Power Relay Assembly) cuts off the main relay in the IG OFF state. 

■ A cooling fan is applied so that the temperature of the high-voltage battery can be maintained

    at an optimal level.
