5.1 High
Voltage System
19
Motor
The motor of the PHEV converts electrical energy
into motive force with a Max. power of 67Hp (50kW)
and Max. torque of 151lb-ft (205Nm).
HPCU
The HPCU 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 transfers high voltage
electricity to 12 voltage to charge 12V auxiliary
battery.
HSG (Hybrid Starter Generator)
The HSG restarts the engine in the ICE/HEV
modes, and also charges the high voltage battery
while driving, as this is the generator for hybrid
vehicle.
PHEV
– High Voltage Battery
High voltage battery modules supply and store
electric energy from traction motor and it is a
Lithium ion polymer battery with specifications,
360V / 27.4Ah / 9.8kWh.
On
-Board Charger (OBC)
The
OBC is the battery charging equipment
that
converts
external AC to DC to charge the high
voltage
battery
