In general, charging stations for electric vehicles are installed with a power output between 3.7 kW and 22 kW. Here are some guidelines regarding the charging speed and power of the charging station:

1. 3.7 kW (230V, 1-phase): This is the standard charging speed for a regular socket (Schuko). It is typically used for slower charging, such as overnight at home. The charging power is approximately 16 amperes.

2. 7.4 kW (230V, 1-phase): This is a faster charging speed available if you have an electric car with a 1-phase charger that supports this power. The charging power is approximately 32 amperes.

   
   

3. 11 kW (400V, 3-phase): This is a common charging speed for electric vehicles that support a 3-phase connection. The charging power is approximately 16 amperes per phase.

   
   

4. 22 kW (400V, 3-phase): This is a higher charging speed available if you have an electric vehicle with a 3-phase charger that supports this power. The charging power is approximately 32 amperes per phase.

   
   

   It is important to check what power your electric vehicle and your electrical connection support before purchasing a charging station. Additionally, it may also be necessary to adjust the electrical installation in your home or business premises to provide the desired power. It is recommended to consult a professional installer to determine the right charging station and required power based on your specific situation.
