Fraunhofer's smart charging station would charge your EV when there was the most municipal power available
Hopefully before too, too long, the majority of vehicles on the road will be electric. There could be one potential problem with all those EV’s in use however - the huge load that would be put on municipal power supplies when all those vehicles are simultaneously plugged in after their owners get home from work. Fortunately, our oft-featured friends over at Germany’s Fraunhofer group have come up with a solution. They’ve designed a station that charges your vehicle when there’s power to spare.
