No. Component Location Description DC/DC Converter Cargo area floor
(mounted right of
Li-ion battery) 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 (headlights, audio system, etc.) .
Service Plug Cargo area floor
(inside storage bin
behind access door) This is used to disable the high voltage system.
Lithium-ion (Li-ion)Battery Cargo area floor
(under 3rd row
seating floor trim) The Li-ion battery stores and outputs DC
power (Maximum voltage 144V) needed to
propel the vehicle.
Traction Motor Engine compart-
ment (built-into thetransmission) Converts three-phase alternating current (AC)
power to drive power (torque) which propels
the vehicle.
Traction MotorInverter Engine compart-
ment (front driverside) Converts the DC power stored in the Li-ion
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.
12V Battery Engine compart-
ment (front driverside) A lead-acid battery that supplies power to the
low voltage devices.
High Voltage Har-ness Cargo area (on
Li-ion battery) ,
under floor, enginecompartment Orange-colored power cables carry high DC
voltage between each of the high voltage com-ponents.
