I have looking into buying a Zoe and as I will need to be charging using the granny charger for a period (whilst we are in the rental and before we buy our next home) I have come across a few people commenting on problems charging using this method due to the earth loop impedance and the ohms is too high. Is this a common issue and how can I make sure this will be ok before buying the car. Ideally I do not want to spend money on the electrics on this home as it is just rented.
Thank you
I think it is the Zoe that is sensitive to earth impedance not the granny lead. I also believe that current charge infrastructure guidance/requirements in the UK actually requires a separate earth spike for all EV chargers these days to avoid risk from supply-side earth faults - unless your charge point or consumer unit feed has PEN protection fitted, which is not yet universal by any means.
