Hybrid Component Locations & Descriptions
Component Location Description
12 Volt Auxiliary
Battery
Left Side of
Trunk
A lead-acid battery that supplies power to the low voltage
devices.
Hybrid Vehicle
(HV) Battery
Pack
Trunk Area,
Mounted to Spare
Tire Area
230.4 Volt Nickel Metal Hydride (NiMH) battery pack
consisting of 32 low voltage (7.2 Volt) modules connected
in series.
Power Cables 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
Engine
Compartment
Boosts and inverts the high voltage electricity from the HV
battery pack to 3-phase AC electricity that drives the
electric motor. The inverter/converter also converts AC
electricity from the electric generator and electric motor
(regenerative braking) to DC that recharges the HV battery
pack.
DC-DC
Converter
for 12 Volt
Auxiliary
Battery
Inverter/
Converter
Converts 230.4 Volts from the HV battery pack to 12 Volts
for low voltage vehicle power.
Gasoline
Engine
Engine
Compartment
Provides two functions:
1) Powers the vehicle.
2) Powers the generator to recharge the HV battery pack.
The engine is started and stopped under control of the
vehicle computer.
Electric
Motor
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
Transmission 3-phase high voltage AC generator that is contained in the
transmission and recharges the HV battery pack.
A/C Compressor
(with Inverter)
Engine
Compartment
3-phase high voltage AC electrically driven motor
compressor.
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.
