Toyota is the leading patent filer in V2G networks. Toyota and Oncor Electric Delivery, a Texas-based electric transmission and distribution company, announced a joint pilot project to conduct research on V2G technology. The initial phase will use Oncor’s Dallas research facility microgrid, which is composed of four interconnected microgrids that can be controlled independently or in parallel, in tandem or in combination. The microgrid and its subsystems include a V2G charger, solar panels and battery storage for testing and evaluation. A battery electric vehicle (BEV) will be used with the system to gain insight into the interconnectivity between BEVs and utilities. Honda, General Electric, Panasonic, Porsche Automobil, and BYD are the other key players in V2G networks.

In terms of application diversity, Murata Manufacturing held the top position, while Causam Energy and BYD stood in second and third positions, respectively. By means of geographic reach, Causam Energy leads the pack, followed by BYD and Sofibol.
