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.

Inspection
Normal Charge Port Relay
Check for continuity between the terminals.
1.
There should be continuity between terminals No.20 and No.10
when power and ground are connected to terminals No.10 and No.9 in the
ICM-A.
Folding Motor Relay
Check for continuity between the terminals.

Safety Precaution
Since electric vehicles contain high voltage batteries,
mishandling the high voltage system or vehicle may lead to a serious
accident, including electric shock and electric leakage.
