Lengthy idle periods with a high charge level may result in an accelerated ageing of the high-voltage battery.
Exhaustive discharging caused by the battery being idle for lengthy periods can damage the high-voltage battery.
Recharge the high-voltage battery if the charge level is insufficient.
You can check the charge level of the high-voltage battery in the multimedia system: More
The electric motor is operated as an alternator when in overrun mode and during braking in order to charge the high-voltage battery while driving.
At a mains outlet (mode 2)
At a wallbox (mode 3)
At a charging station (mode 3)
The high-voltage battery can be charged in a nominal voltage range from 100 V to 400 V.
It is recommended that you charge the high-voltage battery at a wallbox or charging station due to the improved charging performance and better charging efficiency offered.
