More details about California’s proposal requiring bidirectional charging capabilities for all EVs

Charged EVs

In recent testimony, Nuvve CEO Gregory Poilasne told the lawmakers that bidirectional charging can reduce the total cost of EV ownership, and that it’s essential for integrating more renewable energy into the grid. In just a few years, every new EV, on both the consumer and commercial sides, is likely to be bi. That’s one way.
