DESCRIPTION
A lead-acid battery
powera all low voltage
electrical equipment.
288-Volt Nickel Metal
Hydride (NiMH) battery
pack consisting of 30
low voltage (9.6-Volt)
modules connected
in series.
Orange coloured 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, 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.
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 permanent magnet
electric motor contained
in the front transaxle.
Used to power the
front wheels.
3-phase high voltage
AC generator contained
in the front transaxle.
Used to recharge the
HV battery pack.
