Main Components of Electric Vehicle

(1) On-Board Charger (OBC): External device (low speed) to charge the high voltage battery.
(2) Inverter: Transforms direct current into alternating current to supply power to the motor, and transforms alternate current into direct current to charge the high voltage battery.
(2) LDC: Transforms power from the high voltage battery to low voltage (12 V) to supply power to the vehicle (DC-DC).
(2) VCU: Functions as a supervisory controller of electric vehicle
(3) Traction Motor: Drive vehicle converting electric energy of charged battery to mechanical energy (functions same as internal combustion engine)
(4) Reduction gear: Delivers rotational force of the motor to the tires at appropriate speeds and torque.
(5) High voltage battery (lithium-ion polymer): Stores and supplies power necessary for the electric vehicle to operate (12 V auxiliary 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

WARNING

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, have the vehicle inspected by an authorized Kia dealer.
