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.
Boosts and inverts the high voltage
electricity from the HV battery 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.
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.
