High Voltage Battery (Lithium-Ion Polymer); Ev Battery Coolant Heater - Hyundai KONA Electric 2023 Owner's Manual

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.
If over time the maximum charge
capacity and the maximum electric
range appears to have degraded
more than 30% less than at new
condition, 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 % (for example, below
20%). Storing the vehicle with the EV
battery capacity at a low SOC may
damage the battery over time.
CAUTION
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.
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, 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 (for
example, 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 -31°F (-35°C).
