A tethered EV charger extension cable is a type of EV cable that extends the charging range of a tethered charger. Electric vehicle charging extension cables differ significantly from domestic extension cords in terms of their technical specifications. Please note that a domestic extension cord should never be used to charge an electric vehicle. In addition to being unsafe, it is also associated with risks. As well, it can have a negative impact on the warranty of an electric vehicle (EV) or an electric charger.
In order to facilitate the charging of electric vehicles, a portable EV charger is equipped with a number of technical features, including a communication protocol. There is no such requirement for an EV extension cable. As a result, an EV extension cable cannot be used to charge an electric vehicle without a portable or fixed EV charger.
