LOCATIONS AND DESCRIPTIONS
COMPONENT LOCATION DESCRIPTION
12-Volt Luggage A lead-acid battery
Auxiliary Battery Compartment that supplies power to
the low voltage devices.
Hybrid Luggage 288-Volt Nickel Metal
Vehicle (HV) Compartment Hydride (NiMH) battery
Battery Pack Area, Mounted pack consisting of 20
to Cross Member low voltage (14.4-Volt)
and behind Rear modules connected
Seat in series.
Power Under Carriage Orange coloured power
Cables and Engine supply cables carry high-
Compartment 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.
Inverter/ Engine Boosts and inverts the
Converter
*
Compartment 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.
Petrol Engine Provides two functions:
Engine Compartment 1) powers vehicle:
2) powers generator to
recharge the HV battery
pack. The engine is
started and stopped
under control of the
vehicle computer.
Electric Transmission 3-phase high-voltage
Generator AC generator that is
contained in the
transmission and
recharges the HV
battery pack.
Electric Transmission 3-phase high-voltage
Motor AC permanent magnet
electric motor contained
in the transmission and
drives the four wheels
through the transfer case
and propeller shafts.
