Chris Bowe was preparing for his daughter ’s ninth birthday party in February when a sop storm knocked out business leader to his neighborhood in Hayward , California . Minutes before the party begin , Bowe connected his galvanising Ford F-150 Lightning to a instrument panel in his garage , send electricity from the pickup motortruck to his house .
“ It was dark out , parent were dropping off their kid , and our theatre was lit up , ” state Bowe , who work as a FedEx manager in the Bay Area . “ They were like , ‘ How do you have power ? ’ ”
Bowe keep the light on using bidirectional charging , which allows galvanising vehicles to not only receive electricity but discharge it as well . It ’s a feature that a suggest California billwould require that all EVs sold in the country offerby model class 2027 .

ready an EV bidirectional capable is a matter of fit out it with the proper software and hardware , and some , likethe Nissan Leaf , Kia EV 6 , and the Lightning , already provide the feature . Other producer have been dull to flap out the technology . Tesla , for example , state its carswill be bidirectional by 2025 .
exponent of Senate Bill 233 , which the country ’s Senate Appropriations Committee will hear this month , say using galvanic vehicle batteries to world power plate , construction and even the power grid could bring home the bacon Energy Department resilience and bolster grid dependability . clime events and produce power demand more and more stress the state ’s energy supplies . Utilities sometimesshut down power lines to prevent ignitionwhen wildfire danger is high . Storms can causewidespread blackouts , and excess demand when people wrick up air conditioner during estrus waves haveprompted ramble blackoutsto ration tycoon .
The solutions to these outages often rely on fossil fuel that only aggravate the underlying causes . California mightturn on a backup natural gas flora to supply more great power , and homes and business oftendraw power from diesel generatorsduring blackouts .
“ When the grid is stressed , would n’t it be keen if rather of discharge foul fossil - fuel peaker plants typically located in deprived communities , we were using our electric vehicles ? ” said Kurt Johnson , community Department of Energy resiliency director at the California nonprofit organization The Climate Center .
Such a solution is called fomite - to - grid integration , in which EV owner could plug their cars into bidirectional charging station at home and sell the power in its battery to utilities during peak need , buttressing the gridiron and dilute their utility program banker’s bill . Those batteries can also power a home plate or building , or even be used to directly punch in a icebox or essential medical equipment . “ Even the pocket-size unremarkably available EV stamp battery is a multi - day push storage asset for everybody , ” said Johnson . “ A Nissan Leaf can head for the hills your house for days . ”

The throwaway comes as the state takes a prima role in vehicle electrification . Last year , California regulators ask that all novel cars sell in the commonwealth be electric by 2035 , and it already has 1.5 million electron volt on the route . That figure isprojected to reach 8 million by 2030 . All of those cars would have a total capacity of 80 gigawatts of power , according to Johnson . punch in a fraction of them would apace transcend the content of the state ’s largest world power plant , the Diablo Canyon atomic plant , which can provide up to 2.3 gigawatts .
The Alliance for Automotive Innovation , an machine - industry advocacy group , play off the Federal Reserve note . Its representatives declined an interview postulation , but referred Grist to aletter to state senatorsin which it said that a mandate is previous and does not look at the associated costs or the regulative changes call for to make vehicle - to - grid engineering work .
“ mandate bidirectional hardware on the vehicle will not insure that bidirectional charging will take place or will even be capable of taking place , ” it said in the letter of the alphabet . The organization approximate that the applied science could sum up about $ 3,300 to a vehicle ’s toll .
In a Senate Transportation Committee hearing last week , state Senator Nancy Skinner said the mandate would ensure that vehicle sell in the most polar years of the United States Department of State ’s electric transition , which is being driven by generousgrants and rebates , can become energy assets . “ I appreciate that manufacturers do n’t like mandates , but we need to make certain the cars have the capacity while the rebates still exist , ” say Skinner , who introduced the bill .
The alliance also debate that using an EV to deliver major power could adversely impact battery life and undermine barrage fire warrant , which are based on year and milage . However , the battery warranty on the Nissan Leaf , one of the least expensive full bombardment electrical cars available , account for bidirectional charging manipulation . The bidirectional courser okay for use with the Leaf negociate the shelling ’s levels to preserve barrage life .
Even if every EV had bidirectional capacity , getting the energy flow into a home or the grid requires an expensive regalia of ironware . In plus to a bidirectional charging station , the car owner would take an inverter to convert the elevator car ’s DC king to AC , a switch to isolate the scheme from the grid , and a small bombardment to get the system going during an outage . Ford offer an all - in - one software system that costs more than $ 5,000 , not including the price of hiring an lineman to install it .
That was too expensive for Bowe . “ It sounds wonderful , but you ’re still talk about an upper - middle socio-economic class , affluent person in a single - sept home that ’s drop dead to be capable to afford to do this , ” he said . He instead installed a manual transfer electric switch that he connects to his Lightning with the same type of power cord used for a home author . It cost him $ 1,500 .
For those who can yield all the hardware , the framework for connecting with the control grid and selling electricity back to the local utility does not yet exist . “ We ’re not even effectively interlink stationary batteries , much less mobile barrage fire , ” said Johnson . Also , for it to make financial mother wit for EV owners to offer up energy to the power grid , there take to be pricing mechanism for selling the electrical energy to the service program . While a few California utilities have begunvehicle - to - grid pilot undertaking , no official programs live yet .
Johnson said the State Department is put to work on both interconnection and pricing – – there are about a dozen eyeshade accost interconnection woefulness in the legislature , and the public utilities perpetration isstudying new pricing frameworks . He say that SB 233 is meant to be a start point . “ If the vehicles themselves do n’t have the bidirectional capacity , which is the point of the bill , then none of that opportunity can be recognise . So it all starts with the vehicles . ”
