BMW 3: Charging stations

Permanent charging station

This version of the Electric Vehicle Supply Equipment must be installed permanently owing to its size and electrical requirements, e.g. at the house or in the customer's garage. Such a charging station can also be built at public places, e.g. car parks.

The installation, maintenance and repair of permanent charging stations can only be performed by suitably qualified electricians. Employees in BMW Service are not authorized to perform these tasks.

AC charging stations

The connection of the AC charging stations to the AC voltage network is achieved via two-phase supply. In comparison to the mobile solution, a maximum current level of 32 A or a maximum charging power of 7.4 kW is possible. These maximum values are dependent on the size of the wire cross- section used in the electrical installation at the installation site. The electrician configures the charging station during installation according to the wire cross-section so that the applicable maximum current level is transmitted to the vehicle using the pilot signal.

The charging electronics of the G20 PHEV generally only support charging at a maximum power of 3.7 kW. Charging at an excessive current level is avoided through communication via the pilot line and the proximity (charging plug detection) resistor.

The following graphics show an AC charging station and the appropriate connector on the charging cable:

     General information

    Electronic control devices are installed in the vehicle. Electronic control units process data they receive from vehicle sensors, self-generate or exchange with each other. Some control units are necessary for the vehicle to function safely or provide assistance during driving, for instance driver

     Fuel recommendation

    General information Depending on the region, many gas stations sell fuel that has been customized to winter or summer conditions. Fuel that is available in winter, for instance helps make a cold start easier. Gasoline General information For the best fuel efficiency, the gasoline should be sulfur-fr
