No. Component Location Description High Voltage Battery Trunk area (behind
rear seat back) The high voltage battery stores and outputs
DC power (Maximum voltage 400V) needed to
propel the vehicle.
DC/DC Converter Trunk area (mounted
to top of high volt-
age 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 Trunk area (below
parcel shelf; behind
access door in trimpanel) This is used to disable the high voltage system.
12-volt Battery Trunk area (below
parcel shelf; behind
trim panel left of
high voltage battery) A lead-acid battery that supplies power to the
low voltage devices.
High VoltageHarnesses Trunk area (on high
voltage battery) ,
under floor pan,
engine compartment Orange-colored power cables carry high DC
voltage between each of the high voltagecomponents.
Electric Air Condi-
tioner Compressor Engine compart-
ment (front driverside) Air conditioner compressor
Traction MotorInverter Engine compart-
ment (right rearside) Converts the DC power stored in the high volt-
age battery to three-phase AC power and con-
trols motor torque (revolution) by regulating the
motor current. The inverter has a built in high
voltage capacitor.
Traction Motor Built-into the
transmission Converts three-phase alternating current (AC)
power to drive power (torque) which propels
the vehicle.
