A lead-acid battery that supplies power to the low voltage devices.
288 Volt Nickel Metal Hydride (NiMH) battery pack consisting of 40 low
voltage (7.2 Volt) modules connected in series.
Orange colored power supply 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, electrical 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.
inverter/converter also converts AC electricity from the electric generator
and electric motor (regenerative braking) to DC that recharges the HV
battery pack.
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 generator that is contained in the transmission
and recharges the HV battery pack.
3-phase high-voltage AC permanent magnet electric motor contained in
the transmission and drives the rear wheels through the propeller shaft.
3-phase high voltage AC electrically driven motor compressor.
Converts 288 Volts from the HV battery pack to 12 Volts for low voltage
vehicle power.
The fuel tank provides gasoline via fuel lines to the engine. The fuel
lines are routed along the driver side and center tunnel under the floor
pan.
