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 homes 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. 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.

Amazon Go’s ‘just walk out’ tech comes to the LA suburbs.
The new Amazon Go Whittier location is enticing locals with $3 made-to-order Avocado Toast, kombucha on tap, and local beers from Smog City and Three Weavers brewing companies. Torrance location coming soon.
Yummy Google potato chips land in Japan.
You can now enter an official Google Store lottery in Japan to win boxes of Snow Cheese, Hazel Onion, Salty Lemon, or Obsidian Pepper flavored “Google Original Chips.” Get it? Original chips… because the Pixel 7 phones launching on October 6th will be powered by Google’s own Tensor G2 silicon.
Mmm, cheese made from snow.
You can now listen to podcasts inside Twitter.
If you pay Twitter, at least. The latest feature to join the Twitter Blue subscription is early access to the redesigned Spaces tab on iOS, which includes support for tuning into podcasts.
I am not entirely convinced this will take off (short-form social network + long-form audio = ?), but I can see a compelling use case if Twitter eventually lets podcasters promote clips from their shows. My colleague Ariel Shapiro wrote about the launch last month:

I hope every app adds support for Apple’s “Focus filters.” I’d love a future where I can split work and personal stuff between Focus Modes, rather than having to use different apps.
What does it mean to have “brain fog?” Scientists are finally looking into it.
Long COVID isn’t the only thing that can cause brain fog — other culprits include chemotherapy, hormone trouble, and multiple sclerosis — but it’s nice to see that people are starting to take it seriously.

We have the technology to view TV from our wrists, but where is the feature?

The electrical grid has a lot of problems, but EV charging is not one of them — for now.
The Union of Concerned Scientists says that the US electrical grid is up to the EV challenge, even in states like California with a lot of grid problems and a lot of EVs. The group even has high hopes for the future, as EVs grow more prevalent on the road. Utilities and grid operators will need to invest in more capacity and better transmission, though, if and when EVs become the dominant vehicle type on the road.
I bet the 64GB iPhone 12 will be the most popular model this year.
There’s a report from analyst Ming-Chi Kuo going around stating that demand for the iPhone 14 is less than demand for the 13 was last year during the first pre-order weekend. Given how little has changed with the 14, I’m tempted to say “duh” and that we shouldn’t really think about this gen’s performance until the 14 Plus is released, at the very least.
But it also made me think that the 64GB iPhone 12 is going to be this year’s iPhone XR. It’s got what the people want: modern look, lots of colors, and the cheapest price on the shelf.
The iPhone 14 Pro gets a handy feature if you have an Apple Watch.
The new iPhone’s always-on display will apparently turn off if you walk away from it while wearing an Apple Watch. That could save some battery in the long run.
