I'm not a leccy but not being able to have a 32amp circuit seems a bit daft in this day and age of induction hobs, cookers and leccy showers.
Thought most houses were supplied with 80 or 100 amps. Might want to get that checked out, perhaps the fitter was having a bad day!
With bigger battery EVs a car charger at home would definitely be a bonus. I've just been charging at home on a 3 pin socket as the battery in my EV is only 30kWh so does just fine but would def look at getting a charger installed if I stepped up to 60kWh and above.
