> quicker/better Quicker may be true, but "better"? Swap stations are more expensive, they constrain vehicle design, battery shape, and battery technology upgradeability. This makes the vehicle some combination of heavier, less safe, or more expensive (pick your poison). People don't seem to realize that the limiting factor for charge rate isn't current. It's cooling. A far simpler solution would just pump coolant through the charging port so that a large off-board cooler can be used. The cells in the Leaf and Volt could be fully charged in 20 minutes with adequate cooling. Independent (though amateur) tests by RC hobbyists have demonstrated hundreds of cycles at that charge rate with little loss in capacity. http://www.rcgroups.com/forums/showthread.php?t=672512 http://www.rcgroups.com/forums/showthread.php?t=672512
