Notes on charging the high-voltage battery at a fast charging station (mode 4)

DANGER Risk of fatal injury from damaged component parts

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

At charging stations with a pre-installed charging cable:

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

At charging stations without a pre-installed 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.

Always observe the safety notes 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 charging cable for the vehicle must not be longer than 30 m due to the legal requirements in some countries. This is to prevent the interference of signals being received by radio communication devices in the vehicle or in close proximity to the charging station. Be aware that parts of the charging cable may be routed underground. If in doubt, ask the charging station operator if this is the case before charging the high-voltage battery.

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.
