The gist, you might be aware that the history of cars started with electric engines and was replaced with gas when it showed more range. Throughout the history of the automobile, the electric engine popped its head here and there but never captured a following, that is, until the 1990s when AC Propulsion showed its T-Zero could outperform any supercars of the day.
Consider today a Tesla Roadster can do 0 to 60 in 3.9 seconds, have a range of 240 miles, or even the fantastic Lightening GT that will have the same blistering accelerations but sporting 640 horsepower instead of 248 for the Roadster, and you can see how far EVs have come in such a short time. And if these numbers don’t win you over, the Renault Dauphine was fitted with batteries and an electric engine in the late 50′s with a blistering 60mph.
So where is the future of EVs? Lithium batteries have been around for a while and prices have not come down. Same thing with NiHM batteries? Maybe John Petersen’s is right thinking derivative of lead acid based technology will usher a new dawn of affordable ones? Why not. We believe it will be a bit of all of the above. Exclusive cars require the best and lightest, hence a market for lithium. Heavier ones won’t mind the few extra pounds, hence the lead battery makes sense. Ultimately, we do see a hybrid battery making its way into mass production, using ultracapacitators for the quick bursts of energy coupled with different types of batteries.
One thing is for sure, it is a bright future.
