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]
