The most important charging connections in Germany at a glance:
Regular alternating current from the household socket: The advantage is that the electricity is easily accessible and available everywhere. Compatible electric cars can be easily connected via a SchuKo plug. The main disadvantage is the long charging time due to the weak contacts. New is also, that electric vehicles can heat up old Schuko sockets by the long charging time so much that a defect occurs. Loading an electric vehicle with a triple or five-fold socket is a bad idea.
It should be used with an outlet which is rated for 10A continuous load, a separate supply line (if possible without branches between them) and connected by a specialist.
Type 2 with three-phase current: This combination is the European standard as most charging stations and wallboxes work with it. The usual charging capacity is here 11kW or 22kw. Usually the charging cable that has been supplied with the car is taken for the charging process. If the power is higher (e.g. 43kW) a fixed cable is usually already installed on the charging station.
DC with CCS: The Combined Charging System (CCS) is the extension of the Type 2 plug to charge with direct current up to 200A. Europe has agreed that Type2 and CCS should be the standard for electric vehicles charging in Europe.
CHAdeMO: Is the Asian development for charging with DC. Most Japanese electric cars work with this system.
All DC systems have a fixed charging cable attached to the charging stations.
