Charging the high voltage battery

Charging power

Charging power

Charging power is used for charging the high voltage battery as well as preconditioning of the car. Charging takes place with a charging cable connected to the car's charging input socket and a 230 VsocketThe voltage in the socket may vary depending on market. (alternating current) or via a charging station. Different amperage loads can be set in the centre display.

When the charging cable is activated, the driver display shows a message and a lamp in the car's charging input socket illuminates. The car's centre display is activated at the same time and shows the settings for charging. Charging power is mainly used for battery charging, but it is also used for preconditioning of the car. The 12V battery is also charged when the car's battery is charged.

Important

Never unplug the charging cable from the 230 V socket (alternating current) while charging is in progress - there is then a risk of damaging the 230 V socket. Always end charging first before unplugging the charging cable from the car's charging input socket and then from the 230 V socket.

Note

  • If the weather is very hot or very cold, some of the charging current is used to heat/cool the high voltage battery and the passenger compartment, which results in a longer charging time.
  • The charging time is extended if preconditioning has been selected. The time required depends mainly on the outside temperature.
  • Fast charging at up to 140 kW power output is possible in good conditions for high voltage battery and charging station. The charging power is limited towards the end of fast charging.

Amperage

The charging time varies depending on the amperage set in the centre display or the available charging power. The following charging times are applicable when air conditioning or any other consumer is not affecting charging. If charging time seems long, it should be investigated.Maximum charging current may vary depending on market.

Fuse

Normally several 230 V consumers are included in a fuse circuit, so additional consumers (e.g. lighting, vacuum cleaner, electric drill, etc.) can be on the same fuse.

Example 1

If the car is connected to a 230 V/10 Asocket and the charging current is set at 16 A, then the car will attempt to draw 16 A from the 230 Vmains power circuit – after a while the overloaded 10 Afuse for the socket will be tripped and battery charging stopped.

In which case, reset the fuse for the socket and select a lower charging current in the centre display.

Example 2

If the car is connected to a 230 V/10 Asocket and the charging current is set at 10 A, then the car will draw 10 A from the 230 Vmains power circuit. If additional consumers are connected to the same socket (or another socket in the same fuse circuit) then there is a risk that the fuse for the socket/fuse socket will be overloaded and triggered, at which point battery charging is stopped.

In such cases, reset the fuse for the socket/fuse circuit and select a lower charging current in the centre display – or disconnect other consumers from the socket/fuse circuit.

Example 3

If the car is connected to a 230 V/10 Asocket and the charging current is set at 6 A, then the car will only draw 6 A from the 230 Vmains power circuit. Battery charging will of course take longer, but then additional consumers can be connected at the same time to the same socket/fuse circuit as long as the total load does not exceed the capacity of the socket/fuse circuit.
