Old EV batteries are being reused as energy storage devices in CA
Electric vehicles are here to stay, and the subject of what to do with their battery packs once they are no longer suitable for the road remains a key concern among skeptics. A response to these concerns is currently being demonstrated in California by B2U Storage Solutions Inc, a Los Angeles-based startup that’s using second-hand EV batteries as energy storage systems that can support the grid.
B2U noted that its use of old EV batteries can significantly lower the cost of carbon-free energy storage. The company also noted that so far, it has 25 MWh of storage capacity tied to a solar energy site in Lancaster, California. The battery storage system, which is composed of 1,300 old electric car batteries, is believed to be the first of its kind.
The system is promising, with B2U CEO Freeman Hall stating that the batteries earned $1 million last year selling power into the wholesale energy market. Hall also estimates that the use of old EV batteries could reduce the costs of grid-scale battery installations by about 40%. So far, B2U’s system uses batteries from old Honda and Nissan electric vehicles, and some are up to eight years old.
“Second life and re-use helps the overall lifecycle be more energy efficient, given all the efforts that go into making that battery. So you’re getting maximum value out of it,” Hall told Reuters.
What’s especially admirable about B2U’s technology is that its solution doesn’t even require old EV batteries to be disassembled or reconfigured. The batteries themselves are connected into a climate-controlled storage pod sized like a shipping container, and they’re used with their existing casings. The batteries are managed through their existing onboard management software as well.
Electric vehicle leader Tesla is ramping the production of its energy storage devices like the Megapack, which is also designed to support the grid. In the company’s Q4 and FY 2022 Update Letter, Tesla noted that it was able to deploy 6.5 GWh of energy storage in 2022, the highest it has accomplished to date. But despite this, Tesla cannot usher in sustainability alone, so companies like B2U could provide a well-needed boost that could further accelerate the growth of the energy storage market.

Tesla Fremont Factory celebrates 15 years of electric vehicle production
Since opening in 2010, the Fremont Factory has produced all four “S3XY” models while creating tens of thousands of jobs.
Tesla is marking the 15-year anniversary of its Fremont Factory in California, the first automotive mass-manufacturing plant acquired by the electric car maker.
Since opening in 2010, the Fremont Factory has produced all four “S3XY” models while creating tens of thousands of jobs and investing billions of dollars in the region.
Celebrating 15 years of EV production
The Fremont Factory’s milestone was celebrated by the official Tesla Manufacturing account on X, which posted a photo of several Teslas forming a “15” in front of the facility’s iconic white facade. As per the electric vehicle maker, the Fremont Factory has now produced 3.6 million vehicles so far, and it has also created over 20,000 jobs in the state.
“15 years ago, we opened Fremont factory. Today, the Fremont team is producing all 4 S3XY models, totaling 3.6M vehicles made so far. 20k+ California jobs created w/ billions of dollars invested,” the official Tesla Manufacturing account on X wrote in its post.
The Fremont Factory’s transformation
Tesla acquired the Fremont Factory from the defunct NUMMI joint venture between General Motors and Toyota in May 2010 for $42 million. The facility had produced more than 8 million vehicles under GM and Toyota over 26 years. Following its acquisition, Tesla retooled the 5.3-million-square-foot plant to support the production of the Model S sedan.
Over the past 15 years, the factory has evolved into Tesla’s primary North American production hub, assembling the Model S, 3, X, and Y. Annual output has exceeded 550,000 vehicles, including nearly 560,000 produced in 2023 alone. Expectations are high that other products, such as the next-generation Roadster and Optimus, might be produced in the Fremont Factory as well.

Tesla posts job opening for next-generation Roadster production
Elon Musk teased a major demonstration at the Tesla Design Studio in Hawthorne, scheduled for the end of the year.
Tesla has opened its first job listing specifically for the next-generation Roadster, hinting at some substantial progress on the company’s long-awaited flagship all-electric supercar.
The company is looking for a Manufacturing Engineer to support the development and launch of new battery manufacturing equipment, which would likely be pivotal to the Roaster, considering its teased performance and range.
Tesla’s next-generation Roadster batteries
As per Tesla’s Careers website, the Roadster Manufacturing Engineer’s tasks would include ideating equipment concepts, developing specifications, validating processes, and addressing production bottlenecks. Tesla emphasized that the position involves collaboration across domestic and international sites, supporting equipment factory acceptance tests and assisting operations teams, with expected travel under 50 percent.
“In this role, you will take large-scale manufacturing systems for new battery products and architectures from the early concept development stage through equipment launch, optimization, and handover to local operations teams. Battery development is at the heart of our company, and this is an exciting opportunity to work directly on the central challenges for the all-new Roadster product architecture while still in its early development stages,” the job listing noted.
The opening marks one of the first public hiring efforts explicitly tied to the next-gen Roadster, suggesting that the vehicle’s development might be approaching its initial manufacturing phase. The fact that the new Roadster’s first job opening is related to its battery is interesting, as the vehicle was unveiled with a range of 620 miles way back in late 2018. Though at the time, Elon Musk also noted that the Roadster would be fitted with a 200 kWh battery, twice the size of the batteries used in the Model S and Model X.
Musk teases “most epic demo ever” and fuels Roadster speculation
Back in July, Elon Musk teased a major demonstration at the Tesla Design Studio in Hawthorne, California, scheduled for the end of the year. Musk shared on X that he had just visited the studio, calling the upcoming event the “most epic demo ever by one of year. Ever.”
The statement immediately prompted speculations that Tesla may finally be ready to reveal the production version of the next-generation Roadster. Originally unveiled alongside the Semi in 2018, the Roadster has remained under wraps while the company scaled production of other models. Since its unveiling, however, the Roadster’s rollout has been pushed back in favor of the original Model Y, the refreshed Model S and X, the Cybertruck, the refreshed Model 3, the Semi, and the new Model Y.
At the time of its unveiling, the next-generation Roadster was teased to be nothing short of a monster, with a 0-60 mph time of 1.99 seconds and a top speed of over 250 mph. Elon Musk also teased that the next-generation Roadster would have a range of 620 miles per charge. Later, the CEO noted that the Roadster should be able to achieve a 0-60 mph launch of less than 1 second, thanks to the vehicle’s SpaceX package. Musk has also noted recently that the next-generation Roadster would be “beyond a car.”
