Main electric vehicle components

  • OBC (Onboard charger): Transforms (converts) alternating current (AC) charge power to direct current (DC) power to charge the high voltage battery.

  • Inverter: Transforms DC into AC to supply power to the motor. Also transforms alternating current into direct current to charge the high voltage battery.

  • LDC (Low voltage DC-DC converter): Transforms (converts) power from the high voltage battery to low voltage (12V) to supply power to chatge Aux. battery and power up 12v batterys loads in the vehicle.

  • VCU (Vehicle control unit): Supervisory controller of the electric vehicle.

  • Motor: Drives the vehicle using electrical energy stored inside the high voltage battery (functions like a motor in a standard vehicle).

  • Reduction gear: Delivers the motor’s rotational force to the tyres at appropriate speeds and torque.

  • High voltage battery (lithium-ion): Stores and supplies power necessary to electric vehicle operation. The 12V battery provides power to vehicle features such as lights and wipers.

WARNING

  • Do not remove or disassemble high voltage components, high voltage battery connectors, and/or wiring (orange cables). Be careful not to damage high voltage components or the high voltage battery. Damage to the high voltage components or the high voltage battery might cause serious injury and significantly impact the vehicle’s performance and durability.

  • When the high voltage components or the high voltage battery requires inspection or maintenance, have your vehicle inspected by a professional workshop. Kia recommends visiting an authorised Kia dealer or service partner.
