Quick Charge Relay Assembly (QRA) is installed in the high
voltage joint box and it consists of main relays which control the high
voltage. The QRA controls the high voltage between the high voltage
battery pack and the high voltage joint box by BMS control signal. If
the QRA operates, the PRA operates too.
[Main Function]
1.
During rapid charge, it acts as a switch that supplies high voltage to the battery pack.

Description
The system temperature is calculated by the BMS based on 8
temperature sensor signals. And the cooling fan is conrolled in 9 steps
to maintain the normal temperature of high voltage battery system.
The air-cooling method is applied in the cooling system where
indoor air is used ...
