Notes on charging the high-voltage battery at a wallbox or charging station (mode 3)

DANGER Risk of fatal injury from incorrectly installed component parts

Connecting the charging cable to a wallbox using incorrectly installed component parts could cause a fire or an electric shock, for example.

Only connect the charging cable to a wallbox that:

Has been properly installed and
Has been inspected by a qualified electrician

For safety reasons, only use charging cables that have been tested and approved by the manufacturer for charging the high-voltage battery in an electric vehicle.

Never use damaged charging cables.

Do not extend the charging cable.

Do not use adapters.

Observe the safety notes in the operating instructions for the wallbox.

If charging at a wallbox without pre-installed cable, use the optionally available charging cable for wallbox and charging station (mode 3). The charging cable is stowed in a bag in the boot/luggage compartment.

Only use charging cables that have been tested and approved by the manufacturer for charging the high-voltage battery in an electric vehicle.

DANGER Risk of fatal injuries due to damaged components

Connecting the charging cable to a charging station using a damaged component part could cause a fire or an electric shock, for example.

For charging stations with a preinstalled charging cable:

Perform a visual check of the charging station for obvious faults, such as massive damage to the housing or charging cable.

For charging stations without a preinstalled charging cable:

For safety reasons, only use charging cables that have been tested and approved by the manufacturer for charging the high-voltage battery in an electric vehicle.

Never use damaged charging cables.

Do not extend the charging cable.

Do not use adapters.

Make sure to observe the safety information on the charging station.

Most charging stations must be activated before the charging process, e.g. using an RFID card. Observe the on-site operator's instructions for the charging station.

The amount of energy dispensed for the charging process, shown by the charging station, may be higher than the amount of energy actually absorbed by the high-voltage battery. This is the result of different levels of charging losses and is described as recharge efficiency. Charging losses occur, for example, due to heat that builds up when charging or from auxiliary consumers that are switched on. Further information on recharge efficiency can be obtained at a qualified specialist workshop.
