to charge your possible electric car you need to know the charge rate of the batteries, 6-8 hours is common with alot of EV's, 1 hour to 80% full for quality lithium is pretty fast/good, but for the most part the faster you charge the hotter the battery gets and the sooner the ill need to buy another $6,000 lithium battery, it's all based off he charge rate, lead acid is often 10% or less of the capacity in amps/amp hours, so my 220 amp hour battery shouldn't be charged at more then 20 amps, and the normal charge rate is closer to 4 amps or 500 watts, that is with a normal on board charger, a 15 amp outlet can handle 1,500 watts safely without starting your house on fire, but really, you don't want to cook the battery, that is why my cordless tools with it's 15 minute charger has a fan that cools the battery, it's a little battery and has alot of air flow to keep it cool.
