Cables
Undercarriage and
Engine
Compartment
Orange colored power 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, electric motor, and
generator.
Inverter/
Converter
q
Engine
Compartment
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 charges the
HV battery pack.
