Port of Long Beach -- Vehicle-to-Grid -- Botsford Answers Questions
Electric vehicles have the capability of providing power back to a house (V2H), another vehicle (V2V), a building (V2B), and even the grid, also known as V2G.
Mr. Botsford is a member of the Society of Automotive Engineers (SAE) J-3072 committee for AC vehicle-to-grid (AC V2G). He participated in the standards development, particularly in the EVSE portion. Standards development is ongoing as communications protocols (e.g., IEEE 2030.5) and grid connection issues such as IEEE 1547-2018 and California Rule 21 dictate how to interconnect with the grid.
While DC V2G is relatively straightforward and established, AC V2G is anything but. And, of course, AC V2G is where the vast potential of unleashing the energy storage power of EV battery packs lies.
