If equiv to 135mpg and range 250 miles that suggests about $4 to
recharge the battery. Assuming 15cents/kWh thats 26kWh stored energy.

The 3.5 hour home charger needs a 70 Amp 220V supply.
70 * 220 * 3.5 / 1000 = 49 kWatt-hours so the stored energy must be quite
a lot higher than 26kWH otherwise you'd be cooking the batteries +
charger if you lost 23kWH in heat.
