Charging
Everything on this site about putting energy into an electric car, from what a 10 to 80 per cent charge really takes to what it costs. Charging time here is always the measured 10 to 80 per cent window, never the peak kW on the brochure, because the peak is a moment and the window is the wait. Cost is always split between the home rate and a public rapid charger, since those differ by a factor of two and a half. The 7 pieces in this section: 74 electric cars per fast charger — and the states with the most plugs are the worst served, The US has 77,268 fast-charging plugs — and a third of the sites have just one, How many charging stops on a 500-mile drive? Two, in every car — but 34 minutes or 96, How many kWh does it take to charge an electric car? 18 cars, measured from the wall, Home charging at 7.7 kW vs 11.5 kW: how much faster, car by car, Do you need a 350 kW charger? For 9 of these 14 cars, no and What a 10-80% charge time tells you, and why peak kW does not.
