No. Component Location 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).

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.

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.

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.
