Basically, there are two types of electricity for charging:
Alternating current (AC) = normal charging, charging power: 2.3 kW to 22 kW and
Direct current (DC) = fast charging, charging power: 22 kW to currently approx. 350 kW
Both types have different charging times due to the different charging speeds that result from this and require different plugs.
CCS charging, which is widespread in Germany, enables both charging methods. The abbreviation CCS stands for "Combined Charging System". A CCS charging station is a combined charging system that is suitable for charging with both direct current and alternating current. Alternating current (AC) charging is done with the Type 2 plug. The Combo-2 connector is used for direct current (DC) charging.
Again, everything is simpler than it sounds: Most charging stations offer several plugs - but only the correct plug fits on the vehicle coupling. This also applies to the CHAdeMO standard, which originates in Japan, and the U.S. manufacturer Tesla, which offers its own plug and charging system.
You can charge relatively worry-free at over 1,700 publicly accessible charging points in Berlin. Relatively, because the vehicle must fit the charging offer. This sounds more complicated than it is in reality. This is because the charging stations recognize the correct charging method completely automatically. You can connect to the column via corresponding apps on your smartphone or so-called RFD cards, which you can keep in your car or wallet.
This is ensured by the technology installed in the charging points, vehicles and charging cables: The vehicle and charging infrastructure communicate with each other and automatically coordinate the charging method and charging speed. Drive forward, plug in, authorize, charge: Thus, charging usually works smoothly. The Berlin Senat Department for Mobility, Transport, Climate Protection and the Environment provides an overview of Berlin's charging infrastructure in public spaces, including an overview of the current state of expansion.

Charging directly at the parking lot is the strength of the "Wallbox" (wall charging station). It is the little sister of the big charging station: A wallbox is installed indoors (garages, parking decks or even carports), it has one or two charging points and usually charges with up to 11 kW per charging point. It provides a simple and powerful charging option at the company site or at home. The mains connection is implemented in an uncomplicated way, usually a three-phase connection is sufficient, is the same as is required for the electric stove at your home.
In principle, electric cars can be charged from a conventional household socket (Schuko = protective contact). The charging process then takes significantly longer. But, charging at an ordinary 230-volt Schuko socket should only be carried out in exceptional cases, since - especially in older buildings - the wiring is not designed for high and long-lasting charging currents. This can lead to overheating of the lines and - in the worst case - to a fire. Therefore, an electrician should always check the electrical system on site.
The Electromobility Working Group of the Berlin Electrical Guild is available to answer general questions about electromobility. You will find certified craft companies in your area that can assist you with electrical testing as well as the installation of a wallbox. Click here to go to the electrical guild.
To connect the charging infrastructure to the power grid, you should contact the local operator of the distribution grid, in Berlin Stromnetz Berlin GmbH, at an early stage. You can find out about connection modalities and explore potential savings on network tariffs here. Your installation or electrical company will be happy to do this for you.
Would you like to offer your land for the installation of a charging infrastructure?
Then register in the FlächenTOOL for charging infrastructure of the National Infrastructure Control Center as potential properties for the installation of a charging infrastructure. Federal states, municipalities, municipal enterprises, companies or private individuals can offer their properties on the platform. People looking for suitable areas for charging infrastructure can thus obtain an overview of available areas and their features. Alternatively, please feel free to contact our eMO Infrastructure Team. We will be happy to help you find suitable operators.
Vehicles powered by fuel cells refuel with hydrogen. In Berlin and Brandenburg, five hydrogen refueling stations are already available around the clock, with two more in planning. As usual, filling up once takes less than five minutes and is locally pollution- and CO2-free. However, the supply of vehicles in this area is currently very limited. Further information on hydrogen mobility can be found at h2.live.
