@mildpeach As others have noted in reply, slow charging is not a universal shortcoming of all #EV implementations. The #ChevyBolt is a slow charging vehicle, and you don't provide charging station capabilities, which also affect charge speed.
Fast chargers vary in capability and choosing charging stops will necessarily involve some sophistication on the driver's part -- go to a charge point with lots of free spots, but with slower charge rates, or one with a short wait, but with a fast charge?
