Description
a
Traction Motor
Under hood
Converts three-phase AC power to drive power
(torque) which propels the vehicle.
b
DC/DC Converter –
High voltage junction
box
Under hood
This component includes a DC/DC converter and
high voltage junction box (J/B). The junction box
provides electric power from the Li-ion battery to
all high voltage parts of the vehicle. 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 (head-
lights, audio system, etc.).
c
Inverter
Under hood
Converts the DC power stored in the Li-ion bat-
tery to three-phase AC power and controls motor
torque (revolution) by regulating the motor cur-
rent.
d
Electric air condi-
tioner compressor
Under hood
Air conditioner compressor
e
Cabin heater
Under hood
This is the electric heat source for the cabin
heater. It heats the interior of the vehicle.
f
Charge port
Under hood
Connecting port for EVSE (Electric Vehicle Sup-
ply Equipment). Two ports are available: Normal
charge and quick charge (if so equipped).
᭺
7
12V Battery
Under hood
A lead-acid battery that supplies power to the low
voltage devices.
h
Li-ion (Lithium ion)
battery
Undercarriage
Stores and outputs DC power (Maximum voltage
400V) needed to propel the vehicle.
i
High voltage cables
Undercarriage and
Under hood
Orange-colored power cables carry high voltage
current between each of the high voltage compo-
nents.
j
High voltage battery
service disconnect
Rear seat floor
Isolates the battery from the rest of the high volt-
age electrical system.
k
On Board Charger
Cargo area (This unit
is installed behind a
trim panel to prevent
access)
Converts single-phase AC power from a home
power outlet to DC power and increases the volt-
age in order to charge the Li-ion battery.
᭺
12
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.
