AC charging columns are charging columns that are equipped with normal alternating current (AC). As a rule, the power of an AC charging column is 11 kW (at 400 V and 28 A).

• Typical standards for AC charging with 230 V AC are Schuko, CEE-Caravan, HPC (Tesla Roadster), IEC Type 1 and IEC Type 2. Since only small charging power is transmitted, a charging process takes a very long time – 3.8 hours (with 230 V, 16 A) for a 20 kWh car battery.
• Typical standards for AC charging with 400 V rotary current are the CEE rotary power plug and IEC type 2 connector, which means that you can achieve a higher charging power and thus faster charging speeds – approx. 40 minutes (with 400 V, 32 A) for a 20 kWh car battery.
