Main components of electric vehicle
-
OBC: Transforms (inverts) AC power charge power, to DC power, to charge the high voltage battery.
-
Inverter: Transforms direct current into alternating current to supply power to the motor, and transforms alternating current into direct current to charge the high voltage battery.
-
LDC: Transforms (converts) power from the high voltage battery to low voltage (12 V) to supply power to the vehicle (DC-DC).
-
VCU: Functions as a supervisory controller of electric vehicle
-
Motor: Uses electrical energy stored inside the high voltage battery to drive the vehicle (functions like a vehicle in a standard vehicle).
-
Reduction gear: Delivers rotational force of the motor to the tires at appropriate speeds and torque.
-
High voltage battery (lithium-ion): Stores and supplies power necessary for the electric vehicle to operate (12 V battery provides power to the vehicle features such as lights and wipers).
* OBC: On-Board Charger
* LDC: Low Voltage DC-DC Converter
* VCU: Vehicle Control Unit

Do not remove or disassemble high voltage components and high voltage battery connectors and/or wiring (orange cabling). Also, be careful not to damage high voltage components and the high voltage battery. It may cause serious injury and significantly impact the performance and durability of the vehicle.

When inspection and maintenance is required for high voltage components and the high voltage battery, Kia recommends that you contact an authorized Kia dealer/service partner.
