You can build swap stations incrementally though just like they are building these supercharging stations, so I don't see what the difference is, other than swapping is quicker/better.
- todayiamme 14y agoYou're forgetting that in the case of Telsa's car the entire battery pack is a part of the undercarriage and hot swapping in that case is quite difficult.
- jpxxx 14y agoI've heard otherwise: hot-swapping was a design goal if not yet supported.
- schiffern 14y ago> 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
- sbierwagen 14y agocooling ? The Roadster has a water-cooled battery pack, and I assume the Model S does too.
