5.1 High voltage system
1 High voltage battery
Supplies electric energy to traction motor and stores
generated electric energy.
2
High-voltage
Junction box
It supplies electricity from battery to the inverter, LDC,
air conditioner compressor, etc...

ICCU
(OBC + LDC)
Integrated Charging Control Unit (OBC + LDC)
OBC (On-Board Charger)
: Battery charging equipment (AC→DC)
LDC (Low Voltage DC-DC Converter)
: Charge 12V auxiliary battery

Drive
System
Motor
When current flows through the coil, it generates a
rotating magnetic field and generates motor torque.
EV
Transmission
Increases Motor Torque and increased Torque is
transferred to the wheels.
Inverter
DC → AC (from battery to traction motor)
AC → DC (charge using regenerative braking)
5 High-Voltage Cable
The high-voltage cabling is orange per the SAE
standard.
