A lead-acid battery that supplies power to the low voltage devices.
288 Volt Nickel Metal Hydride (NiMH) battery pack consisting of
20 low voltage (14.4 Volt) modules connected in series.
Orange colored power cables carry high voltage Direct Current
(DC) between the HV battery pack, power control unit, and A/C
compressor. These cables also carry 3-phase Alternating Current
(AC) between the power control unit, electric motor, and
generator.
pack to 3-phase AC electricity that drives the electric motor. The
power control unit also converts AC electricity from the electric
generator and electric motor (regenerative braking) to DC that
recharges the HV battery pack.
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.
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 four wheels through
the transfer case and propeller shafts.
Converts 288 Volts from the HV battery pack to 12 Volts for low
voltage vehicle power.
Converts 288 Volts from the HV battery pack to 46 Volts for EPS
and active stabilizer suspension system power. Dull yellow
colored sheathing identifies 46 Volt wires that are routed under the
vehicle body to power the EPS and the active stabilizer
suspension system.
The fuel tank provides gasoline via fuel lines to the engine. The
source fuel lines are routed under the vehicle along the center
tunnel and the return line is routed along the driver side under the
floor pan.
