No. Component Location Description Traction Motor Inverter
Engine compartment
(rear passengerside)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.
Traction Motor Built-into the
transmission Converts three-phase alternating current (AC)
power to drive power (torque) which propels
the vehicle.
Lithium-ion (Li-ion)Battery
Trunk area
(behind rear seatback) The Li-ion battery stores and outputs DC
power (Maximum voltage 400V) needed to
propel the vehicle.
DC/DC Converter Trunk area (mounted to top 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 Trunk area
(below parcel shelf;
behind access door
in trim panel) This is used to disable the high voltage system.
12V Battery Trunk area (left side
behind trim panel) A lead-acid battery that supplies power to the
low voltage devices.
