No. Component
LocationDescription
T
raction Motor Built-into the transmission Converts three-phase alternating current (AC)
power to drive power (torque) which propels
the vehicle.
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-
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
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.
12-volt Battery Trunk area (left side
behind trim panel) A lead-acid battery that supplies power to the
low voltage devices.
High-voltage
Harnesses Trunk area (on high-
voltage battery) ,
under floor pan,
engine compartment Orange-colored power cables carry high DC
voltage between each of the high-voltage
components.

2-3 High-voltage Battery Pack Specifications High-voltage Battery Specifications
High-voltage

battery voltage 346V (400V max.)
Number of high-voltage battery modules in the pack 12 modules (96 cells)
High-voltage battery module voltage 28.8V each
High-voltage battery dimensions 29.63 x 17.81 x 14.85 in.
(752.5 x 452.4 x 377.1 mm)
High-voltage battery weight 108.05 lbs (49 kg)
2-4 High-voltage Safety Measures Circuit insulation
The high-voltage positive (+) and negative (-) circuits are insulated
from
the metal chassis.
Reducing the risk of electrocution The high-voltage components and harnesses have insulated cases or orange-colored coverings which provide insulation and easy
identification.
The high-voltage battery case is electrically connected to the vehicle
ground. This connection helps protect the vehicle occupants and
vehicle dismantlers from high-voltage electrical shock.
Identification The high-voltage components are labeled “WARNING” similar to the
label shown below. All high-voltage harnesses are coated in orange.

35. Follow the procedure below to remove the battery pack
from inside the trunk room.
a. Attach carabiners (A) of sufficient capacity to hold battery weight, in the positions as shown in the
figure, then connect a belt slinger (B) to it. DANGER
Touching high-voltage components without wearing appropriate Personal Protective
Equipment

(PPE) will cause electrocution.
b. Slightly lift battery pack by using an engine crane (A) . DANGER
Touching high-voltage components without wearing
appropriate

Personal Protective Equipment (PPE) will
cause electrocution.
c. Remove the bracket RH (1) . A B
