Researchers developing DC micro smart grid for charging EV fleets; Li-ion, redox flow batteries and renewables

Green Car Congress

Up to 30 electric vehicles at a time can recharge in Fraunhofer IAO’s parking garage. The aim of charge@work is to design a micro smart grid (MSG) capable of supplying the EV fleet with electricity produced exclusively from renewable sources. The MSG is designed as a direct current (DC) grid. Click to enlarge.
