Description
A lead-acid battery that supplies power to the
low voltage devices.
144 Volt Nickel Metal Hydride (NiMH) battery
pack consisting of 20 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 charges the
HV battery pack.
Provides two functions:
1) Powers vehicle.
2) Powers generator to charge the HV battery
pack.
The engine is started and stopped under control
of the vehicle computer.
3-phase high voltage AC permanent magnet
electric motor contained in the front transaxle.
It is used to power the front wheels.
3-phase high voltage AC generator that is
contained in the transaxle and charges the HV
battery pack.
3-phase high voltage AC electrically driven
motor compressor.
