Bidirectional charging may be required on EVs soon due to new CA law
It’s an exciting week for grid resiliency-lovers in California, as Governor Gavin Newsom followed up his earlier smart grid law and signed another law this week which may require bidirectional charging on EVs in the future – though the law has no hard timeline attached, so it may be a while before we see this happen.
Bidirectional charging refers to the capability of electric vehicles to not just take electricity from the grid to charge, but to output electricity in various forms, whether this be vehicle-to-load (plugging in devices, like the 1.8kW capability on the Kia Niro EV), vehicle-to-home (like Ford’s “Intelligent Backup Power” system), or vehicle-to-grid (like the Nissan Leaf is capable of).
While these applications may seem like a party trick, widespread use of bidirectional charging could lead to huge benefits for efficiency, grid resiliency, and enable much greater penetration of renewable electricity generation.
Most electric grids don’t really have trouble meeting the regular everyday needs of electricity consumers, it’s when big spikes happen that things get difficult. Either on a hot day when everyone is using air conditioning, or a day when electricity generation is curtailed for some reason or another, that’s when things get difficult.
And as climate change makes temperatures hotter, California’s grid is often overtaxed on the hottest summer days, which are becoming more numerous. Even worse, methane-burning fossil gas peaker plants are the highest-polluting form of electricity California consumes, and these are currently used at peak times in order to deal with high demand.
One solution to this problem is adding energy storage to the grid which can be dispatched when needed, and which can fill up when the grid is oversupplying electricity. This helps to balance out supply and demand of electricity and make everything a little more predictable.
This is why there has been a push for grid-based storage like Tesla megapacks, which represent a large source of rapidly-dispatchable energy storage.
But there’s another source of grid-connected batteries out there which was right under our nose the whole time: electric cars.
EVs, which are mostly connected to the internet anyway, could be used as a distributed energy storage device, and even called upon to help provide electricity when the grid needs it. We already see this happening with Virtual Power Plants based on stationary storage, but if cars had V2G, theoretically cars could contribute in a similar way – both saving the grid, and perhaps making their owners some money along the way via arbitrage (buying electricity when its cheap and selling it when its expensive).
The problem is, not many automakers have included V2G capabilities in their cars, and in the cars that do have it, not many manufacturers have made V2G-capable equipment, and the ones who have built it haven’t seen that many customers who are interested in spending the extra money to upgrade their electrical systems with V2G-capable equipment.
So there needs to be something to jumpstart all of that, and California thinks it might just have the thing.
New CA law might require bidirectional charging… eventually.
The idea started in 2023 when state Senator Nancy Skinner introduced a bill which would require EVs to have bidirectional charging by 2027.
As this bill made its way through the legislative process, it got watered down from that ambitious timeline. So the current form of the bill, which is now called SB 59, took away that timeline and instead gave the California Energy Commission (CEC) the go-ahead to issue a requirement whenever they see it fit.
The bill directs the CEC, the California Air Resources Board, and the California Public Utilities Commission to examine the use cases of bidirectional charging and give them the power to require specific weight classes of EVs to be bidirectional-capable if a compelling use case exists.
The state already estimates that integrating EVs into the grid could save $1 billion in costs annually, so there’s definitely a use case there, but the question is the cost and immediacy of building those vehicles into the grid.
The reason this can’t be done immediately is that cars take time to design, and while adding bidirectional charging to an EV isn’t the most difficult process, it also only really becomes useful with a whole ecosystem of services around the vehicle.
Even Tesla, which for years has touted itself a tech/energy company and sold powerwalls, inverters, solar panels and so on, is still only gradually trickling its bidirectional Powershare feature out onto its vehicles.
And that ecosystem has been a bit of a hard sell so far. It’s all well and good to tell someone they can make $500/year by selling energy to the grid, but then you have to convince them to buy a more expensive charging unit and keep their car plugged in all the time, with someone else managing its energy storage. Some consumers might push back against that, so part of CEC’s job is to wait to pull the trigger until it becomes apparent that people are actually interested in the end-user use case for V2G – otherwise, no sense in requiring a feature that nobody is going to use.
Electrek’s Take
Given all of these influences, we wouldn’t expect CA to require bidirectional charging any time soon. But it still gives the state a powerful trigger to pull if other efforts, like the recently-signed smart grid law, turn out not to be enough as California works to, grow, clean up, and make its grid more affordable all at the same time.
But having the force of law behind it could turn V2G into less of a parlor trick and more into something that actually makes a difference the way us EV nerds have been dreaming of for decades now (true story: Electrek once turned down Margot Robbie for an interview and instead talked to some engineers about V2G for an hour).
So, telling manufacturers that California may start mandating bidirectional charging soon means that those manufacturers will perhaps start taking V2G more seriously, particularly given the size and influence of CA’s car market. Even if the CEC doesn’t make it a requirement, the threat of it eventually becoming one means that EV-makers will probably start getting ready for it regardless.
There’s no real point to a single person discharging their car into the grid, but when millions of cars are involved, you could work to flatten out the famous “duck curve,” which describes the imbalance between electricity supply and demand. We hear a lot about “intermittency” as the problem with wind and solar, and grid storage as the solution to that, so being able to immediately switch on gigawatt-hours worth of installed storage capacity would certainly help to solve that problem. And we hope this law helps us get just a little closer to that potential future.

![Opinion: it's time to start recommending some Tesla alternatives [update]](https://i0.wp.com/electrek.co/wp-content/uploads/sites/3/2025/05/completey-different.jpg?resize=1200,628&quality=82&strip=all&ssl=1)
For years, Tesla has been the go-to EV recommendation for “normals” looking for a painless, low-effort experience from their first electric cars. In light of questionable recalls and its CEO’s recent involvement in controversial politics, however, people are starting to distance themselves from the trailblazing company.
All that begs the question: what should we recommend to EV noobs now?
UPDATE: you guys had some great suggestions in the comments. I’ve included a few of them in the article, below. Enjoy!
Despite early quality issues and ongoing service headaches, the groundbreaking S3XY lineup of EVs have always had a secret weapon in the form of the Tesla Supercharger network.
That network of dependable high-speed chargers, paired with solid app integration that makes it easy for Tesla drivers to find available chargers just about anywhere in the US, gave the brand a leg up – but no more. By opening up the Supercharger network to brands like Ford, Hyundai, Kia, and others, Tesla has given away its biggest competitive advantage.
Add in charging and route-planning apps like Chargeway, that make navigating the transition from CCS to NACS easier than ever with its intuitive colors and numbers and easy on/off switch for vehicles equipped with NACS adapters, and it feels like the time is right to start suggesting alternatives to the old EV industry stalwarts. As such, that’s exactly what I’m going to do.
Here, then, are my picks for the best Tesla S3XY (and Cybertruck) alternatives you can buy.
Less Model S, more Lucid Air
Developed by OG Tesla Model S engineers with tunes from Annie Get Your Gun playing continuously in their heads, the Lucid Air promises to be the car Tesla should and could have built, if only Elon had listened to the engineers.
With panel fit, material finish, and overall build quality that’s at least as good as anything else in the automotive space, the Lucid Air is a compelling alternative to the Model S at every price level – and I, for one, would take a “too f@#king fast” Lucid Air Sapphire over an “as seen on TV” Model S Plaid any day of the week. And, with Supercharger access reportedly coming later this quarter, Air buyers will have every advantage the Supercharger Network can provide.

Less Model 3, more Hyundai IONIQ 6
Hyundai has been absolutely killing it these days, with EVs driving record sales and new models earning rave reviews from the automotive press. Even in that company the IONIQ 6 stands out, with up to 338 miles of EPA-rated range and lickety-quick 350 kW charging available to make road tripping easy – especially now that the aerodynamically efficient IONIQ 6 has Supercharger access through a NACS adapter (the 2026 “facelift” models get a NACS port as standard).
The company’s sole electric sedan hasn’t seen the same sales success as IONIQ 5, of course – but that has more to do with America’s insatiable lust for crossovers and SUVs than any shortcoming inherent in the IONIQ 6 itself. All the same, Hyundai is helping dealers clear out its remaining 2024 and ’25 models with 0% financing for up to 48 months through June 2nd.

Less Model X, more Volvo EX90
Once upon a time, Mrs. Jo Borrás and I were shopping three-row SUVs and found ourselves genuinely drawn to the then-new Model X. Back then it was the only three-row EV on the market, but it wasn’t Elon’s antics or access to charging, or even the Model X’s premium pricing that squirreled the deal. It was the stupid doors.
We went with the similarly new Volvo XC90 T8 in denim blue, and followed up the big PHEV with a second, three years later, in Osmium Gray. When it’s time to replace this one, you can just about bet your house that the new 510 hp EX90 with 310 miles of all-electric range will be near the top of the shopping list.

Less Model Y, more Kia EV6
If half the fun of driving a Model Y is terrifying your passengers with its straight-line speed, then the Kia EV6 has to be a serious contender for a replacement.
The sporty EV6 GT made its global debut by drag racing some of the fastest ICE-powered cars of the day, including a Lamborghini, Mercedes-AMG GT, a Porsche, even a turbocharged Ferrari – and it beat the pants off ’em. Combine supercar-baiting speed with an accessible price tag, NACS accessibility, $10,000 in customer cash on remaining 2024 models ($3,000 on 2025s) and just a hint of Lancia Stratos in the styling, the EV6 is tough to beat.

Less Cybertruck, more therapy
It’s not bulletproof, it’s not easy to upfit, it shouldn’t be used for towing, and it won’t win in a straight fight against a vinyl picket fence. By just about every standard “truck” metric, the Tesla Cybertruck falls short against the competition from Chevrolet, Ford, and Rivian. On a more subjective front, the Cybertruck has become a symbol for a conservative movement that is (depending on your point of view) either making America great again or plunging a once-great democracy into an era of fascist oligarchy and widespread stupidity.
In short, it’s probably best to skip the CT.
If you disagree with that statement and feel like driving a new Tesla Cybertruck is the key to happiness, I’m not sure an equally ostentatious GMC Hummer EV or more subtle Rivian R1T will help you scratch that particular itch – but maybe therapy might!

There’s no question that electric construction equipment is safer, more precise, and generally better than the diesel equipment it’s replacing, but getting power to that equipment remains a logistical challenge that hasn’t been solved for. With this new mobile Megawatt charging station, however, Komatsu think they’ve found a solution — with up to 6 MW of power!
Developed by Tesla co-founder Ian Wright, Dimaag, and Japanese equipment giant Komatsu, the groundbreaking Mobile Megawatt Charging System (MWCS) promises to bring electricity where it’s needed, anywhere on the job site, then quickly dispense enough energy to get the electric machines under its care back up and running.
And, with Megawatt power delivery on tap, the new Komatsu-Dimaag MWCS can power up equipment assets between shift changes — if it even takes that long!
Komatsu Dimaag mobile charger
The MWCS boasts a compact, high-efficiency DC-DC converter and a long-life, high-discharge-rate Battery Energy Storage System (BESS) on board that can be connected to a DC fast charger itself, or get “trickle charged” between shifts. Both the battery and its control systems make use of an advanced thermal management solution that Komatsu and Dimaag say optimizes both safety and battery life during high-power delivery.
What’s more, that charging capability won’t stop at just one Megawatt. The system is designed to be scalable up to six (6) Megawatts — making it suitable to juice up even the biggest EVs and, frankly, strongly implying that they’ve already got a buyer.
To make sure the MWCS can get all that power where it needs to, wherever it needs to, the machine is equipped with with stout, construction-grade AT tires, 4-wheel drive, and 4-wheel steering to navigate tight surroundings and rough terrains that other solutions wouldn’t be able to get to. And, while it isn’t mentioned in the press release, there’s a common sense idea here that you could, in a pinch, use the MWCS to tow less capable vehicles out of the mud and snow, if needed.
For their part, it seems like the people at Dimaag are pretty happy with the results. “Dimaag is excited to collaborate with Komatsu, introducing our advanced ESS and DC-DC architecture to revolutionize electrification in construction,” stated Ian Wright, VP Engineering at Dimaag. “Off-road vehicle electrification demands practical solutions that not only meet but exceed the performance of equivalent large diesel engine vehicles, while also providing substantial Total Cost of Ownership (TCO) savings. Dimaag’s electrification and high-power megawatt charging systems are designed to achieve this.”
The prototype MWCS shown, above, features a 295 kWh battery pack and an MCS connector delivering up to 1,500 amps and 1,000 volts of power. Komatsu envisions a scenario wherein the mobile charger makes its rounds on the job site charging up equipment and heading back to grid power (if available) to charge itself.
The MWCS made its debut at the bauma construction show earlier this year. Real-world trials are expected to begin this year.
Electrek’s Take
Conceptually similar to the mobile power platform being developed by American firm Dannar, this new mobile Megawatt charging unit has some heavy-hitting names behind it that make it impossible to ignore. Combine that with Komatsu’s ever-increasing push towards full electrification (the two machines shown, above, are all-new in the last 60 days, with more to come) and it really feels like the MWCS is going to be A Real Thing™️somewhat sooner than later.
Stay tuned.
