Main Components of Electric  
Vehicle
•	On-Board Charger (OBC) :  A device 
that charges the high voltage battery  
by converting AC power from a 
charging station to DC power. Inverter 
: A device that transforms direct 
current (DC) from the high voltage 
battery into alternating current (AC) 
to supply power to the electric motor 
and transforms AC back into DC when 
available to charge the high voltage 
battery.
•	 LDC :  An LDC is a Low Voltage DC-to-
DC converter that transforms power 
from the high voltage battery to the 
low voltage battery (12V) in order 
to supply electrical power to the 
vehicle to operate the lights, wipers, 
multimedia, etc.
•	 Electric Motor :  A device that 
converts electrical energy from the 
high voltage battery into mechanical 
energy which is then transferred as 
rotational torque to the wheels in 
order to drive the vehicle.
•	 Reduction gear :  Delivers rotational 
force of the motor to the tires at 
appropriate speeds and torque.
•	 EV Battery (Lithium-ion) :  On board 
high voltage storage device with a 
capacity up to 64 kWh
 
à OBC : On-Board Charger
 
à LDC : Low Voltage DC-DC Converter
 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 HYUNDAI 
dealer.
High Voltage Battery   
(lithium-ion polymer)
•	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. 
•	 Electric range may vary depending 
on the driving conditions, 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 
vehicle electric range.
•	 The high voltage battery is used when 
using the air-conditioner / heater. This 
may reduce the vehicle range. Make 
sure to set moderate temperatures 
when using the air-conditioner/heater. 
•	 Natural degradation may occur with 
the high voltage battery depending 
on the number of years the vehicle 
is used. This may reduce the vehicle 
range.  

Foreword / Electric Vehicle System Overview

•	
If over time the maximum charge  capacity and the maximum electric 
range begin to degrade, contact 
an authorized HYUNDAI dealer for 
inspection and maintenance.
•	 If the vehicle will not be used for 
an extended amount of time, it is 
recommended to fully charge the 
vehicle to 100% before storing, and 
then charge the vehicle periodically 
(approximately every 3 months) 
to prevent the EV battery from 
discharging completely.
•	 AC charge is recommended to keep 
the high voltage battery in optimal condition.  
Avoid storing the vehicle with a low  
battery SOC % (e.g. below 20%).  
Storing the vehicle with the EV battery 
capacity at a low SOC may damage 
the battery over time. 
•	 Make sure to use a designated 
charger when charging the high 
voltage battery. Using different types 
of chargers may have a serious impact 
on vehicle durability.
 CAUTION
•	 If the vehicle is kept at “H (High)”  
for a long period, it may damage 
the high voltage battery and the 
high voltage battery may have to be 
replaced depending on the level of 
degradation. 
•	 If the vehicle is in a collision, we 
recommend that you contact an 
authorized HYUNDAI dealer to 
inspect whether the high voltage 
battery is still connected.
EV Battery Coolant Heater   (if equipped)
When charging your vehicle, the EV  
battery coolant heater may be turned on 
to increase battery temperature when 
the battery temperature is low (i.e. in 
cold weather conditions). This allows 
the EV battery to charge at nominal 
temperatures and helps to improve 
battery life. 
Note that when the vehicle is being  
charged some of the electrical current 
coming from the charger is being 
used to operate the EV battery coolant 
heater. Electrical power consumption 
for charging may be slightly higher than normal.
 CAUTION
The high voltage battery warmer  
system operates when the charging 
connector is  connected to the vehicle. 
However, the high voltage warmer  
system may not operate when battery  
temperature drops below -35°C (-31°F).

[A] : Normal, [B] : Blown
A vehicle’s electrical system is protected  
from electrical overload damage by fuses. 
This vehicle has 2 (or 3) fuse panels, one  
located in the driver’s side panel bolster, 
the other in the motor compartment. 
If any of your vehicle’s lights,  
accessories, or controls do not work, 
check the appropriate circuit fuse. If a 
fuse has blown, the element inside the 
fuse will be melted or broken. 
If the electrical system does not work,  
first check the driver’s side fuse panel. 
Before replacing a blown fuse, turn the 
vehicle and all switches off, and then 
disconnect the negative battery cable. 
Always replace a blown fuse with one of 
the same rating. 
If the replacement fuse blows, this  
indicates an electrical problem.  
Avoid using the system involved and it is  
recommended to consult an authorized 
dealer.
 Information
Three kinds of fuses are used: blade type  
for lower amperage rating, cartridge 
type, and multi fuse for higher amperage ratings.
 WARNING
NEVER replace a fuse with anything but  
another fuse of the same rating. •	 A higher capacity fuse could cause  
damage and possibly cause a fire.
•	 Do not install a wire or aluminum 
foil instead of the proper fuse - 
even as a temporary repair. It may 
cause extensive wiring damage and 
possibly a fire.
NOTICE
Do not use a screwdriver or any other  
metal object to remove fuses because 
it may cause a short circuit and damage 
the system.
