Location
A lead-acid battery that supplies power to the low voltage
devices.
Supplies electrical power to inverter with converter
assembly in accordance with the driving conditions of the
vehicle.
Recharged by electric motor in accordance with the SOC
and the driving conditions of the vehicle.
Accumulates power from the external power source
supplied by plug-in charging.
The power cables (HV floor under wire, HV air
conditioning wire, HV battery charger wire, AC charger
inlet cable, DC charger inlet cable, motor cable) are set
of high-voltage, high-amperage cables that connect the
traction battery assembly with the inverter with converter
assembly, the inverter with converter assembly with the
electric motor, and the inverter with converter assembly
with the compressor with motor assembly.
Converts the direct current from the traction battery
assembly into alternating current for electric motor, and
vice versa (from AC to DC).
Steps down the traction battery nominal voltage of DC
355.2 V to approximately DC 14 V in order to supply
electricity to the electrical components, as well as to
recharge the auxiliary battery.
Drives by electrical power from the traction battery
assembly, generates motive force for the drive wheels.
Generates high-voltage electricity to recharge the traction
battery, during braking, or when the accelerator pedal is
released.
Transmits and receives data between the switches and
sensors.
