VW to enable bidirectional charging on all EVs on its MEB platform starting next year
Bidirectional charging is the technology of the hour. It enables vehicle-to-grid—or should we say, vehicle-to-anything (V2X)—applications, which promise to greatly facilitate the integration of EVs and renewable energy into the grid, to offer opportunities for fleets to offset their electrification costs, and to allow other handy capabilities, such as backup power. Now Volkswagen has given… Read more »
