MAIN COMPONENTS OF ELECTRIC VEHICLE
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).
• Reduction 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).

à LDC: Low Voltage DC-DC Converter
à VCU: Vehicle Control Unit
WARNING
• 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, we recommend that you
contact an authorized retailer of
Genesis Branded products.
High voltage battery
(lithium-ion battery)
• The charge amount of the high
voltage battery may gradually
decrease when the vehicle is not
being driven.
• The battery capacity of the high
voltage battery may decrease when
the vehicle is stored in high/low
temperatures.
• Distance to empty may vary
depending on the driving conditions
(such as outside temperature), even
if the charge amount is the same.
The high voltage battery may expend
more energy when driving at high-
speed or uphill. These actions may
reduce the distance to empty.
• The high voltage battery is used when
using the air-conditioner / heater.
This may reduce the distance to
empty. Make sure to set moderate
temperatures when using the air-
conditioner/heater.
