under floor, engine
compartment Orange-colored power cables carry high DC
voltage between each of the high-voltage
components.
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.

Air conditioner compressor
Traction Motor Engine compartment
(built-into the
transmission) Converts three-phase alternating current (AC)
power to drive power (torque) which propels the
vehicle.
12-volt Battery Rear of the vehicle on
the left side of the
cargo area A lead-acid battery that supplies power to the low
voltage devices.
DC/DC Converter Rear of the vehicle on
the 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.) .
High-voltage Battery Cargo area floor The high-voltage battery stores and outputs DC
power (Maximum voltage 201.6V) needed to
propel the vehicle.
Service Plug Cargo area floor
(inside storage bin
behind access door) This is used to disable the high-voltage system.

2-5 High-voltage Safety System
The
high-voltage safety system is intended to help keep vehicle occupants and emergency responders safe
from high-voltage electricity. • A high-voltage fuse provides short circuit protection inside the high-voltage battery.
• The high-voltage safety system is insulated from the metal chassis.
• Positive and negative high-voltage power cables are connected to the high-voltage battery and arecontrolled by normally open system main relays (SMR1 and SMR2) . When the vehicle is shut off,
the relays stop electrical flow from leaving the high-voltage battery. However, it can take
approximately ten (10) minutes for the high-voltage capacitor to fully discharge. • 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) . HPCM
