jfe engineering corporation is developing a quick charging station that it claims can take a battery from zero charge to 50% full in about 3 minutes. it has two batteries, one that stores electrical energy from the grid and another that delivers it to the car at extremely high current (500-600 ampere), which allows it to use a low voltage power supply. the company claims that even though one station costs about $63,000, that’s roughly 40% less than the competing chademo system.
