LocationDescription
a Lithium-ion
(Li-ion)
Battery Trunk area (behind
rear seat back) The Li-ion battery stores and outputs DC
power (Maximum voltage 400V) needed to
propel the vehicle.
b DC/DC Converter Trunk area (mounted
to top of Li-ion bat-
tery) 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.) .
c Service Plug Trunk area (below
parcel shelf; behind
access door in trim
panel) This is used to disable the high voltage system.
d 12V Battery Trunk area (below
parcel shelf; behind
trim panel left of
Li-ion battery) A lead-acid battery that supplies power to the
low voltage devices.
e High Voltage Har-
nesses Trunk area (on Li-ion
battery) , under floor
pan, engine com-
partment Orange-colored power cables carry high DC
voltage between each of the high voltage com-
ponents.
f Electric Air Condi-
tioner Compressor Engine compart-
ment (front driver
side) Air conditioner compressor
g Traction Motor
Inverter Engine compart-
ment (rear passen-
ger side) 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.
h Traction Motor Built-into the trans-
mission Converts three-phase alternating current (AC)
power to drive power (torque) which propels
the vehicle.
