Nissan LEAF 2023 Owners Manual
3.2.3.2. For 62 kWh battery models (where fitted)
The Li-ion battery warmer does not operate if the normal charger is not connected to the vehicle. To help prevent the Li-ion battery from freezing, do not leave the vehicle in an environment if temperatures may go below -20 °C (-4 °F) unless the vehicle is connected to a charger.
The Li-ion battery warmer helps to prevent the Li-ion battery from freezing when the temperature is cold. The Li-ion battery warmer automatically turns on when the Li-ion battery temperature is approximately -20 °C (–4 °F) or colder and outside temperature is approximately -24 °C (-11 °F) or colder. The Li-ion battery warmer automatically turns off when the Li-ion battery temperature is approximately -18 °C (0 °F) or higher, or outside temperature is approximately -22 °C (-8 °F) or higher.
The Li-ion battery warmer operates when the normal charger is connected to the vehicle, and it automatically uses electrical power from either the external source or from the Li-ion battery.
Connect the charger to the vehicle and place the power switch in the OFF position when parking the vehicle if temperatures may go below -20 °C (- 4 °F). The Li-ion battery warmer automatically uses electrical power from either the external source or from the Li-ion battery. based on the amount of remaining Li-ion battery.
The charging status indicator lights illuminate in a specific pattern when the Li-ion battery warmer operates. The charging status indicator lights use the same pattern to indicate 12-volt battery charging, Climate Ctrl. Timer operation or Remote Climate Control operation (models with navigation system). The charging status indicator lights do not change if the Li-ion battery warmer operates at the same time as the above features. For additional information, refer to
.The automatic climate control automatically turns on when the Li-ion battery warmer uses electrical power from the Li-ion battery. This is not a malfunction. When the Li-ion battery warmer operates, the temperature inside the vehicle may be warmed up.
The Li-ion battery will be automatically charged when the Li-ion battery warmer uses electrical power from an external source. When outside temperature goes below -20 °C (-4 °F) for many days, frequent Li-ion battery warmer operation may occur, and more electric power will be charged from an external source. Do not connect the normal charger to the vehicle if you do not want to turn on the Li-ion battery warmer. In this case, do not leave the vehicle in an environment if temperatures may go below -20 °C (-4 °F).
When the Li-ion battery warmer is already in operation using an external source, it will continue to use the external power even if the power switch is placed in the ON position.
The Li-ion battery warmer will stop if the power switch is placed in the ON position while the Li-ion battery warmer is using electrical power from the Li-ion battery. To turn on the Li-ion battery warmer again, place the power switch in the OFF position.
The Li-ion battery warmer will stop if the charging connector is removed from the normal charger while the Li-ion battery warmer is operating. To turn on the Li-ion battery warmer again, connect the charging connector to the vehicle. The Li-ion battery warmer will operate again after about 1 hour.
The Li-ion battery warmer will stop if the charging connector of the quick charger is connected to the vehicle while the Li-ion battery warmer is operating. To turn on the Li-ion battery warmer again, remove the charging connector of the quick charger from the vehicle.
The Li-ion battery requires more time to charge to the expected level when the Li-ion battery warmer operates.
The predicted charging time displayed on the meter increases when the Li-ion battery warmer uses electrical power from the Li-ion battery.
The Climate Ctrl. Timer or Remote Climate Control (models with navigation system) does not turn on while the Li-ion battery warmer operates. This is not a malfunction.
The charging timer or remote charge (models with navigation system) does not turn on while the Li-ion battery warmer operates. This is not a malfunction.
The Li-ion battery may not be charged to the expected level using the charging timer while the Li-ion battery warmer operates.
If the Li-ion battery warmer automatically stops because of the Li-ion battery temperature or outside temperature change, charging will continue until the Li-ion battery is fully charged.
