A hybrid solar + storage facility comprised of 1,300 second-life EV battery packs is fully operational in California.
Los Angeles-based B2U Storage Solutions, which develops large-scale energy storage systems by reusing EV batteries, owns the system, which is sited north of LA, in Lancaster.
The system is called SEPV Sierra, and it uses B2U’s patented EV Pack Storage (EPS) technology. It’s made up of 1,300 reused EV battery packs that were sourced from Nissan and Honda. None of the EV batteries used need to be modified, and that virtually eliminates repurposing costs.
B2U says it’s also successfully tested Chevy Bolt and Tesla Model 3 battery packs with its EPS system, and that it can be configured to operate any EV battery.
The EPS system continuously monitors and controls each battery to ensure operating specifications are maintained. EPS cabinet controllers and ancillary equipment sense and manage the internal cabinet environment surrounding each battery pack. To mitigate any potential hazards, battery packs are automatically disconnected if any component deviates from its operating specifications and design limits.
SEPV Sierra’s 25 MWh of operational storage capacity is the largest operational UL 9540-certified energy storage system utilizing second-life EV batteries anywhere. (UL 9540 is a safety standard, if you’re wondering.)
SEPV Sierra started commercial operations in 2020, and B2U has been scaling its capacity in phases. SEPV Sierra is interconnected directly to the grid, selling power and grid services into California’s wholesale power market. It generated over $1 million in revenue in 2022 alone. B2U is developing additional projects to add to its operational project portfolio.

Genesis is preparing to shake things up with its most luxurious SUV yet, the GV90. Thanks to a new patent filing, we are getting a detailed look at how its Rolls-Royce-style coach doors will work.
New patent reveals Genesis GV90 coach door system
When Genesis first unveiled the full-size SUV at the NY Auto Show last March, it wasn’t the stunning design or advanced tech that caught everyone’s attention. It was the coach doors.
Although we were worried it wouldn’t make it to the production model, like many concepts, the Genesis GV90 will be offered with coach doors.
The ultra-luxe electric SUV was first caught with coach doors earlier this year on a car carrier in South Korea. Just last month, the GV90 was spotted in California with a hinge at the rear to open the coach doors.

After several new patents were filed with the United States Patent and Trademark Office for new door latching devices, we are getting a sneak peek at how they are expected to work.
The patents, titled “Cinching Device For Door Latches in Vehicle,” and “Door Latch Device for Vehicles,” give a pretty detailed explanation of how the Genesis GV90’s coach doors will operate. The “Door Latch Device” uses a door striker on the lower side of the door, which is opened or closed by a hinge unit.
Unlike traditional doors, which use the B-pillar for support, the device is attached directly to the door itself, allowing for hinge-like movement.
The cinching device works in a similar way. It’s also attached to the door and part of the vehicle. However, unlike most of its kind, Genesis found a way to use a single cinching device to control multiple units. Again, the device is used for B-pillarless doors that swing open.
Genesis already said that B-pillarless coach doors are now feasible in production vehicles. The patent reveals a glimpse into how the luxury automaker could make it a reality.

Although the Genesis GV90 is expected to be offered with coach doors, they will likely not be standard. Other variants, with traditional door handles, have also been spotted testing in the US and South Korea.
Genesis is expected to launch the GV90 in mid-2026. It will be built at Hyundai’s Ulsan plant in South Korea. The flagship Genesis SUV is scheduled to debut on Hyundai’s new eM platform, which the company said will “provide 50% improvement in driving range.” It will also be loaded with the latest technology, software, connectivity, and Level 3 or higher autonomous driving capabilities.

July EV sales looked strong on the surface, but the looming impact of tariffs and the end of EV tax credits reveal a more complicated picture, according to Cars.com’s new Industry Insights report.
New-vehicle sales jumped 6.6% year-over-year, even as dealer inventory fell for the first time since 2022. Much of the spike came from a “buy now” mindset as shoppers raced to lock in deals before tariffs and policy changes drive prices higher. For EVs in particular, the looming end of the federal $7,500 tax credit on September 30 added another layer of urgency.
EV inventory growth is slowing – for now
Shoppers technically have more EV options than ever, with 75 models on the market – a 27% jump from last year. But new EV inventory growth has slowed to just 9% year-over-year, the lowest since before the Inflation Reduction Act revived federal incentives. Analysts expect another wave of buying before the tax credit vanishes, but after that, higher prices could cool demand, especially with most new EVs still priced in the premium-to-luxury bracket.
Tariffs set to push prices higher
Automakers absorbed an estimated $12 billion in tariff costs in the second quarter alone to keep sticker prices steady. That’s not sustainable, and once those costs flow into 2026 models, EV buyers could be facing thousands more on the same car.

At current 25% tariff levels, the average new-vehicle price could jump from $48,000 to $54,400 – about $6,400 more. Even if trade deals trim tariffs to 15%, buyers would still see increases of more than $4,000. That’s a huge gap compared to household incomes, which grew only 1% last year.
The used EV market is heating up
While new EV prices are bracing for impact, the used EV market is gaining momentum. Inventory is up 33% year-over-year, while average prices dipped 2% to $36,000. Affordable used EVs under $25,000 – including the Tesla Model 3, Nissan Leaf, and Chevy Bolt EV – are selling 20% faster than average. Many also qualify for the $4,000 used-EV tax credit, which, like the new EV credit, ends September 30.
The 30% federal solar tax credit is ending this year. If you’ve ever considered going solar, now’s the time to act.
