(EPS photo) Does Subhash Dhar know what he’s talking about when he says he knows the way forward with electric car batteries? Is he on to something when he says his company, Energy Power Systems (EPS), can make storage systems for battery EVs at a quarter their current cost? Turbocharging Lead-Acid Dhar’s breakthrough is not in building a better lithium-ion battery, in fact his solution doesn't use lithium at all. Instead, EPS is going back to basics with the technology that electric cars started out with at the beginning of the 20th century—lead-acid. Dhar says the company is adopting the lessons used in li-ion to vastly improve the efficiency of lead-acid.
