Yeh more than likely a learning experience, i'd be fine for locally charging as work from home so could have it plugged in a lot whereas he's on-site. Where i work have started get charges in the works car park but we have maybe 8-10k people on-site and less than 100 spaces i'd say so i think generally everyone just needs the time to transitioniX1 does 135kW peak, which is pretty reasonable, especially if you consider it'll do 230-250 miles in this weather, so 180-200ish miles before needing to charge, which is 3 hours driving. 10-70% on an iX1 is around 25 mins as it does slow down, as it is a low voltage pack in the car.
Maybe he needs to learn the way his car behaves, as for charging locations, no idea where he is going so can't comment.
