DESCRIPTION
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 coloured power
supply 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 inverter
assembly 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 four wheels
through the transfer case
and propeller shafts.
