Motor
EPCU
The EPCU is the main High Voltage control unit & includes an Inverter and LDC (Low Power DC-DC
Converter) in one housing. The inverter converts DC to AC to supply electricity to the motor.
It also converts AC to DC to charge the high voltage battery. The LDC converts high voltage electricity
to 12 voltage to charge the 12 Volt auxiliary battery.
• There is the capacitor inside the EPCU. Wait 5+ minutes for the capacitor to discharge
after removing the service plug.
On-Board Charger (OBC)
The OBC is the High Voltage battery charging equipment that converts external AC to DC or
direct DC to DC, to charge the high voltage battery.
Motor
The electric motor of the EV converts electrical energy into motive force with a Max. power of
