BMW 3: Introduction
Although the high-voltage battery unit of the G20 PHEV can also be partially charged by energy recovery via the electrical machine, the "normal" charging procedure takes place when the G20 PHEV is connected to the AC voltage network of the local power supply company. Energy is taken from the alternating current voltage network and fed to the direct current voltage high-voltage electrical system.
To allow this to happen, the G20 PHEV can be connected to an AC charge station or charged via the charging cable.
The charging procedure is never carried out with the maximum possible charge current. At the start, charging takes place with constant current. Switchover to constant voltage takes place towards the end. The actual charging time is increased as a result, and the service life of the battery cells is extended.
If the G20 PHEV is connected to an AC charging station, the maximum possible charging power of approximately 3.7 kW is also available (provided the AC charging station is designed for this).

Warning
If the upper retaining strap is incorrectly used
for the child restraint system, the protective effect
can be reduced. There is a risk of injury.
Make sure that the upper retaining strap does
not run over sharp edges and is not twisted as
it passes the upper anchor.
