Hybrid Component Locations & Descriptions
Component Location Description
12 Volt Auxiliary
Battery n
Left Side of
Trunk
A lead-acid battery that supplies power to the low voltage
devices.
Hybrid Vehicle
(HV) Battery Pack
o
Trunk Area,
Mounted behind
Rear Seat
288 Volt Nickel Metal Hydride (NiMH) battery pack
consisting of 40 low voltage (7.2 Volt) modules connected
in series.
Power Cables p Undercarriage and
Engine
Compartment
Orange colored power cables carry high voltage Direct
Current (DC) between the HV battery pack,
inverter/converter, and A/C compressor. These cables also
carry 3-phase Alternating Current (AC) between the
inverter/converter, electric motor, and generator.
Inverter/
Converter q
Engine
Compartment
Boosts and inverts the high voltage electricity from the
HV battery pack to 3-phase AC electricity that drives the
electric motors. The inverter/converter also converts AC
electricity from the electric generator and electric motor
(regenerative braking) to DC that recharges the HV
battery pack.
Gasoline Engine
r
Engine
Compartment
Provides two functions:
1) Powers vehicle.
2) Powers generator to recharge the HV battery pack.
The engine is started and stopped under control of the
vehicle computer.
Electric Motor s
Transmission 3-phase high voltage AC permanent magnet electric motor
contained in the transmission and drives the rear wheels
through the propeller shaft.
Electric Generator
t
Transmission 3-phase high voltage AC generator that is contained in the
transmission and recharges the HV battery pack.
A/C Compressor
(with inverter)u
Engine
Compartment
3-phase high voltage AC electrically driven motor
compressor.
DC-DC Converter
vfor 12 Volt
Auxiliary Battery
Engine
Compartment
Converts 288 Volts from the HV battery pack to 12 Volts
for low voltage vehicle power.
DC-DC Converter
w for EPS
On HV Battery
Pack
Converts 288 Volts from the HV battery pack to 46 Volts
for EPS. Dull yellow colored sheathing identifies 46
Volts wires that are routed under the vehicle body to
power the EPS.
Fuel Tank and Fuel
Line
Undercarriage,
Left Side and
Center
The fuel tank provides gasoline via a fuel line to the
engine. The fuel line is routed along the left side and
center tunnel under the floor pan.
