Yes, it is possible to charge at home with 3-phase, but it requires some specific conditions and adjustments to your electrical installation. Here are some important points to consider:

1. Electrical connection: To be able to charge with 3-phase, you need a 3-phase electrical connection in your home. This means that three power wires must be available, often referred to as L1, L2, and L3. A standard household connection in the Netherlands is a 1-phase connection with one power wire (L1). To switch to 3-phase, you must contact your grid operator to check if an upgrade of your electrical connection is possible.

2. Charging station: You need a charging station (charging pole) that is suitable for 3-phase charging. Not all charging stations support 3-phase charging, so you must ensure that you purchase a charging station that is compatible with 3-phase connections. When choosing a charging station, it is important to consider the maximum charging power the station can deliver and the requirements of your electric car.

3. Installation: Installing a 3-phase charging system often requires modifications to your electrical installation. This may include adding extra power wires and a suitable 3-phase residual current device. It is important to consult a professional electrician for the installation to ensure it is carried out correctly and safely.

4. Grid load and costs: Using 3-phase charging can affect your grid load and electricity costs. The higher charging power can result in a higher peak load and possibly higher electricity costs, depending on your rate structure. It is advisable to contact your grid operator and energy supplier to discuss how 3-phase charging may affect your electricity connection and costs.

It is important to mention that not all electric vehicles support 3-phase charging. Therefore, check the specifications of your electric car to ensure that it is compatible with 3-phase charging before making changes to your electrical installation.
