No but it is advisable. You can use a household 3-pin socket to charge an EV. However, we strongly recommend having one of our specialist units installed for safety reasons: 3-pin sockets are not designed for continuous high power EV charging and can overheat. Using a specially designed charger and cable, monitors the continuity of the earth conductor.
If this conductor breaks the charger will not operate for safety reasons, protecting you and your home wiring. Dedicated units are also able to charge an EV more quickly at higher power, and are installed in locations where cables won’t be a trip hazard.
