Can I run an electric car on 100 or so NiMH AA batteries hooked in series?
The Tesla roadster, for instance uses some 6831 lithium-ion batteries. So while maybe you don’t to go that fast, and maybe you don’t need a 250 mile range on one recharge…100 camera batteries won’t get you out of the driveway. http://www.popularmechanics.com/science/research/4212847.html In fact, NiMH batteries have half to a quarter of the energy density of Lithium-ion types. NiMH batteries max out around 1800 BTUs, Lithium-ion start at 3600 BTU and really efficient ones go to 7200 BTUs. The unfortunate news is that battery-based cars are not the answer and will not move us away from gasoline-based vehicles for a long time. Gasoline is attractive because it yields 115,000 BTUs per gallon. Diesel is the only thing, other than burning plastic, that beats it out – and then not by that much. So…I wish it’d work, but no dice.
