NOTE:
Components with white number in black background are high voltage components.No. Component
LocationDescription
a Charge

port Under hood Connecting port for EVSE (Electric Vehicle
Supply Equipment) . Two ports are available:
Normal charge and quick charge (if so
equipped) .
b High voltage
cables Under hood and
undercarriage Orange-colored power cables carry high volt-
age current between each of the high voltage
components.
c Traction Motor Under hood Converts three-phase AC power to drive
power (torque) which propels the vehicle.
Inverter Under hood Converts the DC power stored in the Li-ion
battery to three-phase AC power and controls
motor torque (revolution) by regulating the
motor current.
Electric air condi-
tioner compressor Under hood
Air conditioner compressor
Power Distribution
Module (PDM)
• On Board Charger
• DC/DC Converter
• High voltage junction box (J/B) Under hood
The PDM includes an On Board Charger, DC/DC
converter and high voltage junction box (J/B) .
The On Board Charger converts single-phase AC
power from a home power outlet to DC power and
increases the voltage in order to charge the Li-ion
battery.
The DC/DC converter reduces the voltage of the Li-ion
battery to provide power to the 12V battery in order to
operate the vehicle’s electric components (headlights,
audio system, etc.) .
The J/B provides electric power from the Li-ion battery
to all high voltage parts of the vehicle.
d 12V Battery Under hood A lead-acid battery that supplies power to the low
voltage devices.
e Cabin heater Interior (This unit is
installed behind the
instrument panel) This is the electric heat source for the cabin
heater. It heats the interior of the vehicle.
f Li-ion (Lithium ion)
battery Undercarriage Stores and outputs DC power (Maximum voltage
398.4V) needed to propel the vehicle.
g High voltage battery
service disconnect Rear seat floor Isolates the battery from the rest of the high volt-
age electrical system.
h Brake power supply
backup unit Cargo area (This unit
is installed behind a
trim panel to prevent
access) Power supply backup unit for the brake system. It
supplies power to the brake system if a malfunc-
tion occurs in the 12V battery.
