The vast majority, at the moment. Last year's figure for EV owners was 40% could charge at home/work, 60% couldn't. We've got to assume that those early adopters would be skewed towards those that can more easily charge. Blind guess would be currently perhaps 90% of car owners would not have access to charging facilities at home/work or would not easily be able to install those facilities. Close to 100% in town, with the remainder being out-of-town countryside dwellers. Things are changing, and over the coming years home/work charging will become easier. But for the moment, it is damn hard.
