Characteristics of Your Electric Vehicle

The characteristics that differentiate electric vehicles from gasoline vehicles are as follows:

  • Electric vehicles are eco-friendly because they do not use fossil fuels for driving. Additionally, unlike gasoline vehicles, noise and vibration are minimal, and the vehicle's lifespan is relatively long.

  • When slowing down or driving downhill, regenerative braking is used. Regenerative braking charges the high voltage battery and minimizes energy loss.

  • If the high voltage battery is running low, you can charge the vehicle using the AC charger, DC charger, or portable charger. For more information, refer to the "Charging Your Electric Vehicle" section in this chapter.

Regenerative braking uses an electric motor when decelerating and braking, and it transforms kinetic energy to electrical energy in order to charge the high voltage battery.

Battery information

The batteries used in the electric vehicle are as follows:

  • High voltage battery (high capacity): Drives the motor and operates the air conditioner and heater. It can be charged via an AC charger, DC charger, or portable charger.

  • 12 V battery: Operates all lights, wipers, and audio system. It is automatically charged while the ¢ indicator is displayed on the instrument cluster or the high voltage battery is charged.

Main components of your electric vehicle

The main components of your electric vehicle and their functions are as follows:

  • On-Board Charger (OBC): Charges the high voltage battery by converting the power grid's AC power to DC power.

  • Inverter: Converts power from direct current (DC) to alternating current (AC) and supplies power to the motor, and converts power from AC to DC and charge the high voltage battery during deceleration and braking.

  • Low Voltage DC-DC Converter (LDC): Converts the high voltage battery's power source to a low voltage (12 V) power source and supply power to the electrical devices in the vehicle.

  • Vehicle Control Unit (VCU): Controls the various controllers and sensors on the vehicle.

  • Motor: Uses electricity accumulated in the high voltage battery to drive the vehicle (same role as an engine in gasoline and diesel vehicles).

  • Reducer: Delivers the 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. (The separately installed 12 V battery provides power to the vehicle when the vehicle is in ACC or OFF.)

  • Do not remove or disassemble any high voltage battery's connectors and wires. Doing so may lead to accidents, such as electric shock, and result in serious injury and significantly degrade the vehicle's performance and durability.

  • When the high voltage battery or its related components require inspection and maintenance, contact an authorized HYUNDAI dealer.
