DC/DC
Converter Inside the centerconsole area
(mounted right 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 Center console
(inside storage bin
under access door) This is used to disable the high-voltage system.
High-voltage
Battery Inside the center
console area
(between the
front driver’s and
passenger’s seats) The high-voltage battery stores and outputs
DC power (Maximum voltage 144V) needed to
propel the vehicle.
Traction Motor Engine compart-
ment (built-into the
transmission) Converts three-phase alternating current (AC)
power to drive power (torque) which propels
the vehicle.
Traction Motor
Inverter
Engine compartment
(front driver side)Converts the DC power stored in the high-
voltage 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.
12-volt Battery
Front of the vehicle
on the left side of the
engine compartment.A lead-acid battery that supplies power to the
low voltage devices.
High-voltage
Harness Center console area
(on high-voltage
battery) , under floor,
engine compartment Orange-colored power cables carry high DC
voltage between each of the high-voltage
components.

• The high-voltage system and high-voltage capacitor may remain powered for up to
approximately 10 minutes after the vehicle is shut off. Appropriate Personal Protective
Equipment (PPE) must always be worn when touching or working on high-voltage
components to avoid risk of electrical shock and severe personal injury or death.
• The high-voltage battery retains high-voltage at all times. Appropriate PPE must always be worn when touching or working on high-voltage components to avoid risk of electrical
shock and severe personal injury or death.
• A ground fault monitor continuously monitors for high-voltage leakage to the metal chassis while the vehicle is running. If a malfunction is detected, the HPCM (hybrid powertrain control module) will
illuminate the hybrid system warning lamp in the instrument cluster.
•
The high-voltage battery relays (SMR1 and SMR2) will automatically open to stop the electrical flow
in a front, side or certain rear collisions that are sufficient enough to activate the supplemental
restraint system (SRS) . Passenger Compartment
