1
High Voltage Battery —
Approximately up to 450 Volts
DC
Located under the vehicle. Liquid
cooled lithium ion battery.
Provides High Voltage storage
for the vehicle electric motor and
for the other High Voltage
components.
2
High Voltage Wiring
Runs underneath the vehicle
from the high voltage battery to
the under hood engine
compartment. All High Voltage
wiring is orange in color.
Provides the physical connection
between the High Voltage
system and High Voltage
components.
3
Under hood passenger side of
vehicle.
Convert DC power to 3-Phase
AC power to drive motor.
4
High Voltage Electric Motor /
Front Module Hybrid Unit
Mounted between Engine and
Transmission under vehicle.
Housing electric motor, torque
convertor and clutch to connect
and disconnect the electric
motor. The electric motor
provides traction to the vehicle
and generate power to storage
on the battery.
5
Electronically Controlled
Transmission
Mounted next to the engine
similar to non-hybrid vehicles.
This transmission includes a
hybrid drive unit with a High
Voltage electric motor and a
integral disconnect clutch.
6
Gasoline Engine
Mounted in the engine
compartment similar to non-
hybrid vehicles.
This engine operates similar to
non-hybrid vehicles.
7
Electric A/C Compressor
Located in front of the engine. It
has an orange high-voltage wire
attached to it.
Provides electric A/C operation.
Replaces the belt driven A/C
compressor.
8
DC/DC Converter
Located under the hood on the
passenger side, mounted forward
of and below Inverter System
Controller (ISC).
Provides 12 volts to charge the
12-volt battery and run vehicle
accessories.
9
Component: On Board Generator
Inverter (OBGI)
Located under the vehicle in
forward of the high-voltage
battery on passenger frame rail.
To convert DC power to AC to
power the "Pro-Power On Board"
outlets in the bed and cabin of
vehicle.
10
12 Volt Battery
Located under the hood on the
passenger side of the vehicle.
The battery is a 12V DC source
connected in a negative ground
system and is a voltage stabilizer
for the 12V electrical system.
11
12 Volt Auxiliary Battery
Located under the RH rear seat.
The auxiliary battery provides
support for transient electrical
loads that occur during a crank
event when the main engine
compartment battery is isolated
from the rest of the vehicle and
unable to provide transient
support.
