Description
A lead-acid battery that supplies power to the
low voltage devices.
207.2 Volt Lithium-ion (Li-ion) battery pack
consisting of 3.7 Volt cells connected in a
series circuit.
Orange colored power cables carry high
voltage Direct Current (DC) between the HV
battery assembly, 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 assembly 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 assembly.
Provides two functions:
1) Powers vehicle.
2) Powers generator to charge the HV battery
assembly.
The engine is started and stopped under
control of the vehicle computer.
3-phase high voltage AC 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 assembly.
3-phase high voltage AC electrically driven
motor compressor.
