Hi, New PHEV due at the weekend. We will be towing a caravan with it and am aware of weight limits, limitation of towing on EV etc. But I am wondering if anyone can advise me if it is possible to charge the car when we are on a caravan site,via one of the 3 pin electric sockets on the van ? Would it depend on the amps provided by the sites electrical system ? Thanks for your help, Alex.
