The difference between single-phase and three-phase charging lies in the number of phases on which the electricity network is based and how electricity is delivered to the charging station.

In a single-phase electricity network, electricity is delivered via one phase. This is the most common type of electricity network and is used in most homes and small businesses. Charging stations connected to a single-phase electricity network can deliver electricity with a charging capacity of up to approximately 11 kW.

In a three-phase electricity network, electricity is delivered via three phases. This type of electricity network is more frequently used in larger companies and industrial buildings and provides a higher capacity for delivering electricity. Charging stations connected to a three-phase electricity network can deliver electricity with a charging capacity of up to approximately 22 kW.

The difference in charging capacity between single-phase and three-phase charging can be significant if you are considering purchasing a charging station for your electric vehicle (EV). If your EV requires a higher charging capacity, such as 22 kW, it may be necessary to purchase a charging station connected to a three-phase electricity network instead of a station connected to a single-phase electricity network.
