MAIN COMPONENTS OF ELECTRIC VEHICLE
• Do not intentionally remove or
disassemble high voltage
components and high voltage
battery connectors and wires.
Also, be careful not to dam-
age high voltage components
and the high voltage battery. It
may cause serious injury and
significantly impact the per-
formance and durability of the
vehicle.
• When inspection and mainte-
nance is required for high
voltage components and the
high voltage battery, we rec-
ommend that you contact an
authorized HYUNDAI dealer.
WARNING
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).
• Motor : Uses electrical energy stored inside the high voltage battery to
drive the vehicle (functions like an engine 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 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
