Crem said: (quoted from post at 12:51:03 12/04/09) An interesting thing is that just last evening at a Car Club meeting it was mentioned that someone in our city has a 1911 electric car on display. What killed that one?
There were several electric car companies in the 1930's. You could even get you Dodge converted to electric by one company. What happened? Essentially same problem as today. You just can't stuff much propulsion energy into a battery. Half a ton of batteries, $30,000 and you have 16KW-hrs that takes you about 40 miles. That is the amount of energy in 0.4 gallon of gasoline. (And yes, there are unaccounted for inefficiencies in both the gasoline and battery charging/discharging, etc.) The situation was worse in 1930 because the volume & weight of 1930 batteries for 16KWH of energy was much greater than with today's batteries.
