Many thanks @kezo and @MFillingham I think I’m slowly getting there and I really appreciate you trying to explain it all.
I think I now understand that you divide the kWh figure by the kWh charger speed to work out how long it will take to charge. Do public chargers have universal charge cables that fit all cars (in the same way the petrol or diesel pumps do), or do you have to have cables of your own for the different types of charger? There was a really heavy and bulky charging cable in the iX1 I had the other day. Would that be the sort of thing you have to have with you in order to charge at 130kwh?
I still don’t understand why EVs quote two different figures (e.g. VW ID5 128kw & 77kwh, Audi Q4 150kw & 82kwh and Mustang 198kw & 70kwh). What does the first kw figure mean? I presume it’s not battery capacity, because that’s the kWh figure, and it’s maybe not power either as BEVs still quote a bhp figure?
