In a three-phase electrical network, the power supply consists of three phases, namely phase 1, phase 2, and phase 3. In 2-phase charging, two of these phases are used.

In 2-phase charging, the available electricity is distributed over two phases instead of all three phases. This results in a lower charging power compared to 3-phase charging because less electricity is available. The charging power in 2-phase charging is typically half of the charging power in 3-phase charging.

For electric cars equipped with an onboard charger suitable for 2-phase charging, using a 2-phase connection can be beneficial in situations where a 3-phase connection is not available. It allows for charging at a higher power than with a single-phase connection.

It is important to note that not all electric cars are suitable for 2-phase charging. Some models may only have an onboard charger suitable for 1-phase charging, while other models may be suitable for both 1-phase and 3-phase charging. It is advisable to consult the specifications of your specific electric car to determine which charging options are available.
