With a one phase charger, the current flows through only one wire, while with a three-phase charger, the current is divided over three wires, allowing it to handle more power. A 1-phase charging station uses a standard 230-volt connection and a standard fuse of 16 amps. A meter box contains a 1-phase connection as standard.
A 3-phase charging station uses 3×230 volts. This is also known as power flow. This point also has a standard fuse of 16 amps. Because the current is distributed over three wires, this charging point has a higher maximum charging capacity.
Just like with a meter box, you can choose to purchase a one-phase or a three-phase charging point. The advantages of a 3-phase connection are a faster charging time and multiple batteries can be charged at the same time. However, the battery of the car must be suitable for 3-phase charging.
