Foreword / Electric vehicle system overview
śꢀ Natural degradation may occur with
the high voltage battery depending
on the number of years the vehicle is
used. This may reduce the distance to
empty.
śꢀ When the charge capacity and
distance to empty keep falling, we
recommend that you contact an
authorised HYUNDAI dealer for
inspection and maintenance.
śꢀ If the vehicle will not be in use for an
extended period of time, charge the
high voltage battery once every three
months to prevent it from discharging.
Also, if the charge amount is not
enough, immediately charge to full
and store the vehicle.
śꢀ AC charge is recommended to keep
the high voltage battery in optimal
condition.
CAUTION
śꢀ If the vehicle is kept with insufficient
charge 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.
śꢀ If the vehicle is in a collision, we
recommend that you contact an
authorised HYUNDAI dealer to
inspect whether the high voltage
battery is still connected.
śꢀ Using the V2L function may reduce
the mileage due to the use of high
voltage battery energy, and repeated
use of the V2L function may cause
a decrease in the life of the high
voltage battery.
High voltage battery warmer
system
The high voltage battery warmer system
prevents reduction of battery output
when battery temperature is low. If the
charging connector is connected, the
warmer system automatically operates
according to the battery temperature.
Charging time may shorten compare to
vehicles without the high voltage battery
warmer system. But, electricity charge
may increase because of high voltage
battery warmer system operation.
If the high voltage battery charge
amount is below 20%, you can keep
the high voltage battery performance
in optimal condition if you charge the
high voltage battery to 100%. (Once a
month or more is recommended.)
The value of the high voltage battery
charge level may vary according to
the charging conditions (state of
charger, outside temperature, battery
temperature, etc.). In order to fully
charge the battery, the current of the
high voltage battery will be gradually
decreased, so that the longevity and
safety of the battery can be secured.
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).
