Exactly spot on. That's the problem with electric vehicles as well - one gallon of gasoline has the equivalent of 56 KW of energy. Even the high-tech battery packs in vehicles such as the Prius, weighing hundreds of pounds, are lucky if they even have one-third of that (ie, the equivalent of 1/3rd of a gallon of gas) TOTAL capacity, with useable capacity being much less.
