I’m not sure about that, but if you’re using a rapid charger, you wouldn’t need anywhere near that amount of time. My local Lidl has a 50kw charger, Tesco next door has a 50kw charger, and the M&S next to it just has installed 6x 150kw chargers.
Ignore my comment mate, I had 7kW in my head, which was from a comment elsewhere and of course totally different than charging at 5okW lol.
