Location
A lead-acid battery that supplies power to the low voltage
devices.
244.8 Volt Nickel Metal Hydride (NiMH) battery pack
consisting of 34 low voltage (7.2 Volt) modules connected
in series.
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.
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.
Converts 244.8 Volts from the HV battery pack to 12 Volts
for low voltage vehicle power.
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.
3-phase high voltage AC motor contained in the transaxle. It
is used to power the front wheels.
3-phase high voltage AC generator that is contained in the
transaxle and recharges the HV battery pack.
3-phase high voltage AC electrically driven motor
compressor.
The fuel tank provides gasoline via a fuel line to the engine.
The fuel line is routed along the driver side and center
tunnel under the floor pan.
