EV extension cord

an extension cord for a EV needs to ensure it’s safe, to avoid an electrical fire.

  • don’t coil it when in use
  • ensure it doesn’t get too hot.
  • don’t use any extension cord, ensure it covers the specs needed and can be used outdoors. (and in rain)
  • dont use 2 25ft cables, use 1 50ft cable, because plug connections add significant resistance.
  • If you were to use a cable that had a lower max rate than your vehicle, and you plugged it into a charger that was capable of more than the cable could handle, it could create a fire hazard (so if your vehicle does 48A, and you got a 32A cable, and plugged it into a 40A or 48A EVSE, it would be a major fire hazard).

do

  • get a higher duty thicker one so there is less resistance on the cord

examples

  • UK lead buy here (best) 25m 80£ inc VAT & delivery
  • also some on amazon, but often the rain proof cover doesn’t fit chunky EV charger plugs. e.g. this review
  • consider 35£ this no rain cover, or 50£ this raincover
