DESCRIPTION
A lead-acid battery
that supplies power to
the low voltage devices.
288-Volt Nickel Metal
Hydride (NiMH) battery
pack consisting of 40
low voltage (7.2-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, electrical
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 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 rear wheels
through the propeller
shaft.
