LocationDescription
DC/DC
Converter Cargo area floor(mounted right of
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 vehi-
cle’s electric components (headlights, audio
system, etc.) .
Service Plug Cargo area floor
(inside storage bin
behind access door) This is used to disable the high-voltage system.
High-Voltage
Battery Cargo area floor
(under 3rd row
seating floor trim) The high-voltage battery stores and outputs
DC power (Maximum voltage 144V) needed to
propel the vehicle.
Traction Motor Engine compart-
ment (built-into the
transmission) Converts three-phase alternating current (AC)
power to drive power (torque) which propels
the vehicle.
Traction Motor
Inverter Engine compart-
ment (front driver
side) 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. The inverter has a built in
high-voltage capacitor.
12-Volt Battery Front of the vehicle
on the left side of
the engine compart-
ment A lead-acid battery that supplies power to the
low voltage devices.

compartmentOrange-colored power cables carry high DC
voltage between each of the high-voltage com-
ponents.
