No. Component
LocationDescription
Charge
port Under hood Connecting port for EVSE (Electric Vehicle
Supply Equipment) . Two ports are available:
Normal charge and quick charge (if so equipped) .
High-voltage cables Under hood and
undercarriage Orange-colored power cables carry high-voltage
current between each of the high-voltage
components.
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 high-voltage
battery to three-phase AC power and controls
motor torque (revolution) by regulating the motor
current.
Electric air
conditioner
compressor Under hood
Air conditioner compressor
Power Delivery
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
high-voltage battery.
The DC/DC converter reduces the voltage of the
high-voltage battery to provide power to the
12-volt battery in order to operate the vehicle’s
electric components (headlights, audio system,
etc.) .
The J/B provides electric power from the
high-voltage battery to all high-voltage parts of
the vehicle.
12-volt Battery Under hood A lead-acid battery that supplies power to the
low voltage devices.
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.
High-voltage battery Undercarriage Stores and outputs DC power (Maximum voltage
398.4V) needed to propel the vehicle.
High-voltage battery
service disconnect Rear seat floor Isolates the battery from the rest of the
high-voltage electrical system.
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
malfunction occurs in the 12-volt battery.

3-4.2 Indications the High-voltage System is ON
1. If the READY indicator is ON, the high-voltage system is active.
2.

The high-voltage system is active if any charge indicator
is ON (blue LEDs on top of the instrument panel) .
Before disconnecting the 12-volt battery terminal, if necessary, lower the windows, unlock the doors, and
open the rear hatch as required. Once 12-volt battery is disconnected, power controls will not operate.
3-4.3 Powering Down the High-voltage System
The high-voltage system can be shut down with any 1 of the following procedures: • Turn OFF the power switch anddisconnect the 12-volt battery.
Refer to 3-4.4 Primary Procedure (DG–21) .
•

Remove the fuses for the high-voltage control system and disconnect the 12-volt battery.
Refer to 3-4.5 Alternate Procedure 1 (Remove Fuses) (DG–22).
•

Remove the service plug and disconnect the 12-volt battery.
Refer to 3-4.6 Alternate Procedure 2 (Remove Service Plug) (DG–25). AAYIA0155ZZ
