which claims to be a specialist. One potential international car-charging standard as of 2010 is SAE J1772 ("SAE Surface Vehicle Recommended Practice J1772, SAE Electric Vehicle Conductive Charge Coupler"): a North American standard for electrical connectors for EVs maintained by the Society of Automotive Engineers, rated 120--240V AC at up to ~17kW. Zerocarbonsta's Can the Grid take it? suggests that the 250bn miles/year driven in the UK in (30M!) cars each year might at 5 miles per kWh of electricity and thus 50TWh/y only add 12% to total grid demand. Especially at night that should be no trouble at all. Without Hot Air's Performance data for a GWiz in London averaged 21kW per 100km or about 5km per kWh. Overview of early electric cars (1895-1925): "One hundred years ago electric cars were a common sight on city streets in Europe and the United States. Many of them had a range comparable to that of today's EVs."
