Question

Cindy has a car that runs on gasoline, and the car can hold 16 gallons under full-tank. Assume the efficiency of the gasoline-based system is 20 %. Now, Cindy wants to convert this car to a fully electric transmission, which runs on a 300 Vdc battery bank and has an efficiency of 60 %. To achieve the same useful output energy, what should be the Ampere-Hour (A.hr) rating of the battery bank?
