In some says, Tesla's Supercharger network is its ace in the hole -- you can buy one of the company's electric cars knowing that you'll have speedy charging when away from home. BMW and Nissan aren't going to let this competitive edge go unanswered, though. They're launching a network of 120 dual-format fast chargers (both CHAdeMO and CCS) across 19 US states, any of which should bring most EVs up to 80 percent in less than 30 minutes. The stations should be available now, and you can find them in the automakers' respective mobile apps.
