Portable Electric Car Chargers Travel To Where They're Needed Most

Electric car "range anxiety?" Real, says GM, anyway. So, to limit the potential for mass hysteria as future commuters' e-tank gauges slide slowly towards E, a solution is needed. Mitsubishi's portable, networked charging stations could be a start.

The portable prototype networked charging stations are the work of Zafer Sahinoglu, at the Mitsubishi Electric Research Laboratories in Cambridge, Massachusetts, and they'll do pretty much what you might think:

To determine where the stations are needed, in-car sensors would monitor the level of charge in the battery and periodically report this to a central operations centre, which would flag areas where most cars run low on juice. The stations can then be deployed wherever the low-charge "hotspots" are at that time. Just five mobile stations would be needed to cover 100 electric cars on a 100-kilometre stretch of highway, the team says. - New Scientist

To reduce strain on the grid, the portable stations would fill up with juice at night, when demand is low, and then dispense their energy goodness to thirsty vehicles during the day. [New Scientist, Image]
