Wired has an article on BMW's foray into recharging networks for electric vehicles - BMW Launches Its Answer to Tesla’s Supercharger Network.
The biggest problem automakers selling electric cars face is limited range. No one wants to get caught without any juice. To get around this concern, Tesla, whose Model S offers the best range (up to 265 miles), is building a vast network of “Supercharger” stations that make it possible to take epic road trips. Now BMW is following suit, launching a network of charging stations to make owning its first all-electric car, the range-handicapped i3, more convenient.
The automaker announced last week that it has developed an impressively small, lightweight, and inexpensive charger that it is working to install around the country. BMW will sell the charger to “authorized partners”—starting with dealers—for $6,548. NRG eVgo, a private EV-charging company, will install at least 100 around California and offer free charging to i3 owners through the end of 2015.
The 24 kilowatt BMW i DC Fast Charger, developed with Bosch Automotive, can charge the i3’s battery up to 80 percent in 30 minutes. Compared to other chargers on the market, the BMW version is quite small: 31 inches tall, 19 inches wide and 12 inches deep. It weighs just 100 pounds, light enough to be mounted without reinforcing the wall or pouring extra concrete.
