Wallbox (home wall charger)
A wall-mounted EV charger that charges with AC from its own circuit in the panel and communicates with the vehicle for safe charging.
Technical level:Basic
A wallbox is fixed to a wall or a post in the garage or open parking area and is fed by a dedicated circuit with its own protection in the panel. Unlike a cable plugged into a household socket, it communicates with the car and supplies power only when everything is correctly connected, so it can deliver higher power for many hours safely.
Typical ratings are 7.4 kW on a single-phase supply and 11 kW on a three-phase supply, which is usually enough to fill the battery overnight. There are models with a fixed cable or with a Type 2 socket for your own cable.
Before buying, ask an electrician to check whether the supply and the panel can handle the extra load; otherwise a lower power or dynamic load balancing will be needed.
