The electrical installation of the house must have the capacity required for the electrical needs of the charging station to prevent short circuits. It must also conform to the AREI (General Regulations on Electrical Installations). But charging stations can be installed single-phase or three-phase.
Advice on this will be given during the conversation prior to installation. Indeed, it depends on parameters such as: the presence of large energy consumers (sauna, swimming pool, etc.), the chosen vehicle, the desired load capacity, etc.
