Assume that an automobile has a 15 gallon fuel tank, and it is possible to refill the tank in 5 minutes. The fuel tank contains 33 kWh per gallon. If the vehicle were to be replaced by an electric vehicle that charges from the power grid, how much power would it draw (in W, kW, or MW) to recharge at the same rate as the gasoline powered automobile?
A Tesla Model S contains an 85 kWh battery and can be charged at a rate of 22 kW. Assuming no losses (100% efficency), how long (in hours) will the car take to charge?
The gasoline powered car has a range of 375 mi, and the Tesla Model S has a range of 300 mi. How much more efficient in terms of miles per kWh is the Tesla than the gasoline powered car?
