The Nikkei newspaper (subs. req’d) says that a Japanese company has built a quick charge system that can take a battery from zero charge to 50% full in about 3 minutes.
Also, because the system works off of trickle charging a contained battery, it can charge its own batteries when utilities charge the lowest rates (typically at night), thereby saving the business and the customer money.
