A invoice at present making its manner via the California legislature would require all new EVs offered within the state to be outfitted with bidirectional charging functionality by 2027. SB 233, which has handed the Senate Power Committee and shall be heard earlier than the Senate Transportation Committee on April 25, would additionally set up state targets for bidirectional charging, enhance funding for bidirectional infrastructure, and promote interoperability testing.
“EVs are vitality storage on wheels. Why waste that battery, given how few miles most individuals use the car in any given day?” stated the invoice’s sponsor, State Senator Nancy Skinner (D-Berkeley). “However we have to make it as straightforward as attainable.”
By most accounts, a 60 kWh EV battery might present backup energy to a median US family for a minimum of two to 3 days. Such a V2H characteristic might be extremely helpful in California, the place residents face a rising menace of rolling blackouts in periods of peak demand.
California’s automobiles could have 60,000 megawatts of saved vitality in batteries by 2030, Siva Gunda of the California Power Fee instructed GovTech. If simply 10% of that might be returned to the grid, “we are able to get via what we went via final 12 months with out turning on the backup turbines.”
Utility PG&E says it’s making ready the grid for the bidirectional future, however warns that the state just isn’t prepared for fast widespread adoption. “It represents a brand new path. We need to lead the nation in reliability, resiliency and lowered emissions,” stated Aaron August, VP of PG&E’s Utility Partnerships and Innovation, including that requirements to assist V2X functions are actually in improvement.
Gregory Poilasne, the CEO of bidirectional charging pioneer Nuvve, just lately testified earlier than the California Senate Power, Utilities and Communications Committee in assist of the proposed laws. “California should strategy V2G the identical manner it has handled rooftop photo voltaic or EV adoption—with targets, incentives and fostering stakeholder collaboration,” he instructed lawmakers. “SB 233 does all three, and can assist remodel right this moment’s kilowatts and megawatts of cell grid storage into tomorrow’s gigawatts.”
