Nissan: V2G? It's not about draining someone's battery.

Nissan talked about V2G technology, a system in which electric vehicles connected to chargers serve as energy storage for the electrical grid. According to a company representative, this is not about unloading someone's car to zero.

A vehicle connected to the grid (V2G) serves as a buffer that collects "excess" energy from the grid and returns it when needed. So this is about leveling the valleys and mountains of demand, not about unloading someone's car. Nissan is currently offering V2G services to the Danish fleet and is starting technology testing in the UK:

In response to a question from The Energyst, a BMW board member said the adoption of V2G technology depends on how well it works. And he adds that the ability to make money just by plugging a machine into the network can be tempting for recipients.

It is worth noting that Tesla has also implemented the ability to return energy to the grid in vehicles at an early stage of operation. However, from a legal point of view, this turned out to be too difficult, so the company refused this opportunity.
