Volkswagen electric cars will get two-way charging


Bidirectional charging is one of the characteristics of electric vehicles, but not all. While the new system is offered by brands such as Nissan, Hyundai and KIA. Volkswagen is also working on this for MEB models. The system will appear in 2022.

One of the drawbacks of the German giant’s MEB platform for electric vehicles is the lack of some interesting technologies, such as bi-directional charging, a system that allows you to charge the vehicle’s battery as well as return excess energy to the grid or serve as an energy generator to power the home in the event of a grid failure. .

This technology is already offered at the Nissan LEAF and was recently implemented on board a new South Korean zero-emission engine based on the e-GMP platform. Meanwhile, Renault is also embarking on a pilot project to conduct bi-directional stress tests, and the Volkswagen ID.3 and ID.4 will be able to return energy to the grid starting in 2022. With this technology, Volkswagen intends to catch up with its greatest rivals. According to Thomas Ulbrich, member of the Volkswagen Group’s Technical Development Board, “prototypes are on the way, preparations are now in their final stages.”

At the moment it is not known if this will be a standard feature or will be offered as an option, if already sold units have to go through official services for technical adaptation, or if it will be equipment included in one of the wireless software updates, which, according to the German brand, will be offered every three months.

While bi-directional charging is a very interesting piece of equipment, it is also true that it is only possible with larger batteries and more autonomy. One of the big problems that has prevented the technology from spreading so far is, of course, the high cost of batteries and their useful life. And the fact is, increased use of the device leads to an accelerated loss of storage capacity.
