Ford unveils C-MAX Solar Energi concept; “plug-in” hybrid not dependent on electric grid can fully recharge from sun

Green Car Congress

Ford Motor Company announced the C-MAX Solar Energi Concept, a sun-powered hybrid vehicle that can deliver the efficiency of a plug-in hybrid without depending on the electric grid for recharging. This could be especially important in places where the electric grid is underdeveloped, unreliable or expensive to use.

NREL study finds that uncoordinated plug-in vehicle charging could prove challenging to the grid

Green Car Congress

An influx of plug-in electric vehicles (PEVs) charging without coordination could prove challenging to the nation’s electric grid, according to research conducted by the US Department of Energy’s National Renewable Energy Laboratory (NREL). This effect is exacerbated when higher in-home power charging is adopted.

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. EV charging at IZS. The MSG is designed as a direct current (DC) grid.
