Nissan has approved the first bidirectional charging system for use with its all-electric Leaf vehicle in the US. The FE-15 charger by Fermata Energy, which can power buildings using the EV’s battery, charge it, and send stored energy back to the grid, is the first system of its kind to earn UL 9741 certification for bidirectional charging solutions.

Back in 2012, Nissan promised its maybe soon-to-be-discontinued EV would eventually share its stored battery power back to your home or the grid during peak hours or even in emergencies. This technology is broadly known as Vehicle-to-Grid (V2G), Vehicle-to-Home (V2H), and Vehicle-to-Load (V2L), which all can be used interchangeably to describe a system that converts EVs to a backup power station.

Other automakers also have bidirectional charging solutions as well, including Ford’s Intelligent Backup Power feature available for its all-electric F-150 Lightning truck. There’s also the Hyundai Ioniq 5 and 6 V2L feature that can make them great camping companions. Tesla, on the other hand, is bearish about the concept, pushing instead its dedicated PowerWall battery backup solution — the same one that it scales to the size of virtual power plants.

it could help reduce stress on the power grid

For Nissan and Fermata, the solution is straightforward. In a press release, Fermata Energy CEO David Slutzky said that the Leaf owners can “create additional value from the energy stored in the vehicle’s battery” and that the charger can help reduce the EV’s total cost of ownership by letting the building pull energy from it at peak times. Slutzky says it could also help reduce stress on the power grid, a problem that, while it doesn’t exist right now, could be an issue in the future unless utilities and grid operators make the right investments.

All model year 2013 and newer Nissan Leafs are approved for use with the FE-15 bidirectional charger, and the automaker states that battery warranties will not be affected. You’ll need to have a quick-charging CHAdeMO port on the Leaf to take advantage of bidirectional charging, which sometimes didn’t come standard. Notably, the 2013 model of the Leaf received a more robust but similar capacity 24kWh battery than the 2012 model, and although previous models did have an option for fast charging, Nissan might not want to be responsible for the batteries’ health rapidly depleting.

Those interested in the FE-15 charger can contact the company through their website. As far as home use, company spokesperson Daniel Cherrin tells us “That will have to wait for now.” Fermata Energy isn’t the only product in Nissan’s sight, though — the automaker is also working with another company called Dcbel that is creating a home-specific bidirectional charging solution.

It’s amazing to see the CHAdeMO charging standard suddenly having a last hurrah. The port is slowly disappearing at various charging stations as CCS Combo has taken over. A new feature like this is great to see and a great story to add to the Leaf’s legacy.

Correction September 13th, 11:26AM ET: A previous version of this article suggested that the FE-15 charger can be installed in homes. It’s currently only available to power other buildings and the grid. We regret the error.

There’s a surprise in the sky tonight.

Jupiter will be about 367 million miles away from Earth this evening. While that may seem like a long way, it’s the closest it’s been to our home planet since 1963.

During this time, Jupiter will be visible to the naked eye (but binoculars can help). You can check where and when you can get a glimpse of the gas giant from this website.

Missing classic Mario?

One fan, who goes by the name Metroid Mike 64 on Twitter, just built a full-on 2D Mario game inside Super Mario Maker 2 complete with 40 levels and eight worlds.

Looking at the gameplay shared on Twitter is enough to make me want to break out my SNES, or at least buy Super Mario Maker 2 so I can play this epic retro revamp.

The US might still force TikTok into a data security deal with Oracle.

The New York Times says the White House is still working on TikTok’s Trump-era data security deal, which has been in a weird limbo for nearly two years now. The terms are basically the same: Oracle plays babysitter but the app doesn’t get banned. Maybe it will happen now, though?

Vietnam’s EV aspirant is giving big Potemkin village vibes

Idle equipment, absent workers, deserted villages, an empty swimming pool. VinFast is Vietnam’s answer to Tesla, with the goal of making 1 million EVs in the next 5-6 years to sell to customers US, Canada and Europe. With these lofty goals, the company invited a bunch of social media influencers, as well as some auto journalists, on a “a four-day, multicity extravaganza” that seemed more weird than convincing, according to Bloomberg.

Today, 39 years ago, the world didn’t end.

And it’s thanks to one man: Stanislav Petrov, a USSR military officer who, on September 26th, 1983, took the decision not to launch a retaliatory nuclear attack against the US. Petrov correctly guessed that satellite readings showing inbound nukes were faulty, and so likely saved the world from nuclear war. As journalist Tom Chivers put it on Twitter, “Happy Stanislav Petrov Day to those who celebrate!” Read more about Petrov’s life here.

Deepfakes were made for Disney.

You might have seen the news this weekend that the voice of James Earl Jones is being cloned using AI so his performance as Darth Vader in Star Wars can live on forever.

Reading the story, it struck me how perfect deepfakes are for Disney — a company that profits from original characters, fans' nostalgia, and an uncanny ability to twist copyright law to its liking. And now, with deepfakes, Disney’s most iconic performances will live on forever, ensuring the magic never dies.

They haven’t confirmed any connection with the GTA 6 leak or Uber hack, but the details line up with those incidents, as well as a suspect arrested this spring for the Lapsus$ breaches.
