Hold on there! A lead-acid battery can be charged at thousands of amps if it's below 80% SOC. To view it from another angle, a battery can usually charge as fast as it can discharge. I'm sure there are exceptions, but in my experience, most drivers seldom decelerate dramatically faster than they accelerate. That said, supercaps have been shown to be useful in mitigating peak currents on discharging, and maybe this would help too on charging. But I suspect that further battery refinement - and the extra cost of the caps - will make this a moot point. > Electric vehicles are coming, ready or not. Ready or not? I don't know how we could possibly be more ready. Some of us have been waiting 40+ years. Such breathless "journalism"! I'm not so sure this does EVs any favors.
