I took delivery of a replacement Smart EV and immediately ran into charging problems at home. The car will not connect to either the 13 amp charger or a Chargemaster 7kw charger. I had all our electrics checked and the Chargemaster unit replaced and the car then charged. However a couple of days later the same problem arose. If I plug in in the neighbours garage there is no problem. I can only think it is something to do with the quality of the power being delivered to our house. Everyone is baffled including 4 different electricians who have been out to investigate. I will leave out the story of the EV which had to be rejected as that is another saga without a conclusion.
