The battery loses 10% just by charging it.
I figured an EV is worth about 60mpg with a fair comparison to a gas car.

A good visualisation for this I think are linked. Petrol/diesel use about 20% of the available energy and electric vehicles use about 80-90% for moving the vehicle.

A litter of petrol is about 34MJ or about 9.5kWh
It propels a car about 10 miles. About 1 mile per kWh
Charging my electric car via AC at 7kW to replace the power used to drive 90 miles in autumn takes 26kWh according to the meter, so 3.5 miles per kWh.
Oil also loses quite a bit during refining and transport.
And more every year as the highest quality oil gets used up and we have to work harder to catalyze the rest.
