Main Components of Electric Vehicle

On-Board Charger (OBC) : A device that charges the high voltage battery by converting AC power of the power grid to DC power.
Inverter : Transforms direct current into alternate current to supply power to the motor, and transforms alternate current into direct current to charge the high voltage battery.
LDC : Transforms power from the high voltage battery to low voltage (12 V) to supply power to the vehicle (DC-DC).
VCU : Control the various controls on the vehicle.
Motor : Uses electrical energy stored inside the high voltage battery to drive the vehicle (functions like an engine in a standard vehicle).
Gear : Delivers rotational force of the motor to the tires at appropriate speeds and torque.
High voltage battery (lithium-ion battery) : 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).

Do not intentionally remove or disassemble high voltage components and high voltage battery connectors and wires. 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, contact an authorized HYUNDAI dealer.
