BMW, Ford, Honda to Form New EV Charging Company

The Truth About Cars

Engineers have discussed the assumed need for localized energy storage as the demand for electricity grows and tapping into EVs could be a clever way of avoiding having to construct warehouse-sized battery hubs. The companies are hoping to sell the concept as a way to help “decarbonize” the energy grid.

Greenlings: Benefits of charging stations vs. battery swaps vs. home charging

Tony Karrer Delicious EVdriven

Gallery: Plugging in at home Battery swap stations are a concept often associated with Better Place , an EV infrastructure company. The idea is that when your car needs more energy, you can drive your car into a station and, like an automated car wash, your depleted battery is replaced robotically by one that has a full charge.
