Gasoline is burned at about 30-40% efficiency in cars while charging a battery is above 90%, probably over 95% (after the charger losses, that is whats going across the cable into car). So with a gas pump your looking at more like 7-8MW equivalent. Even then EV's are more efficient at spending the energy with regenerative braking and no idle losses etc. which is why you 100+MPGe. So your probably closer to 3-4MW to get equivalent charge times as filling a normal car gas tank at like 2-3 minutes for similar range. HPCVC charging spec is being worked on for 3 megawatts but its really targeted for charging large vehicles like Semi's but I would imagine that would trickle down to normal cars at some point if the issues of charging a battery that fast can be worked out.
