According to E.ON, the number of so-called "bi-directional" electric vehicles in Germany, which can not only draw energy but also feed it back into the grid, is growing. More than 166,000 EVs are already "bidi-ready". Their batteries could supply power for up to 1.75 million households for twelve hours. Along with the advent of bi-directional wallboxes, the technology is currently being tested for comprehensive use on a national level. eon.de 🇩🇪
