Auto Makers Announce Electric Car Charging Standard
Overly Critical Guy writes "Auto makers are launching a universal EV charger that charges an electric vehicle in 15 to 20 minutes. The standard, called Combined Charging System, has been approved by the Society of Automotive Engineers and ACEA, the European association of vehicle manufacturers, as the standard for fast-charging electric vehicles."
Often when it comes to fast charge solutions, the quoted time is to reach 80% charge. The remaining 20% usually take a relatively long time because it's slower to charge a battery that's almost fully charged. You can see this in action pretty clearly if you own a laptop.
It's too late. All the Japanese manufacturers standardized on CHAdeMO for charging.
According to http://news.cnet.com/8301-11128_3-57427823-54/automakers-heres-how-well-charge-evs-in-15-20-minutes/ it is rated at 500 volts at 200 amps. So the total KWh for fifteen minutes would be 25.
