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.

    A reputable spark will be able to determine if your house load is able to support the 7kW charger on an 80A fuse (but for me, probably yes), and do the DNO paperwork too - if this is done beforehand then the DNO is able to say if the supply is sufficient. The Zappi is a good fit too as it has the load management as said by others. Clamp meter or data logger will also determine max load but you can usually estimate it pretty easily.
