Cart before the horse? (EV charging)

AncientMariner

Am looking at replacing our 1999 diesel engined car ideally with an EV.

Would obviously want to charge with a 7 kW unit so the question is would our existing Grey Series 7 II b cutout with an 80A fuse fitted be capable of 7 kW or only 3.6 kW. 

So before I even look at a car, I really need to know.  Emailed SP Energy Systems “Getting Connected” and get the reply, “Please be advised that when your installer submits the notification form for the charger, the property will be surveyed and anything required will be carried out as part of that.”  Ok then, I buy the car and then find out that I can only charge at the 3.6kW rate. I could of course have a charging point fitted first, but then would not be able to claim any subsidy or dealer offer.

    For most drivers under most conditions, 3.6 kw charging should be fine.

    A fairly common battery capacity is about 40 kwh, so about 11 hours overnight will fully charge the battery, and that is making the VERY pessimistic  assumption that the battery will be fully discharged.

    I feel that both the electricity distribution industry, and the writers of regulations, and the electrical contracting  industry  are over complicating what should be a simple affair.
