Researchers at WMG, University of Warwick have announced that they have found a way to repurpose old Jaguar I-PACE batteries as potential off-grid small energy storage systems. The repurposed units will contain about 2 kWh of energy capacity, and will likely be enough to power a small shop, a farm holding, or a residential unit.
The Warwick University researchers faced a number of challenges in its project, particularly when it came to preserving the used I-PACE batteries to retain their charge capacities. The lithium-ion cells, for one, had to be protected from overcharging, and the researchers had to design the system in such a way that it could be compatible with cells and modules from other manufacturers. A custom management interface was also developed to make the energy storage system more user-friendly.
WMG’s Professor James Marco, the lead researcher in the initiative, explained the project in a press release.
“When an electric vehicle’s battery reaches the end of its useful life it is by no means massively depleted. It has simply reached the end of its useful life in a vehicle. It is generally accepted that an EV battery has reached end of life when its capacity drops to 80% of a fresh battery. While this is no longer enough to satisfy drivers, it remains immensely useful for anyone who seeks to use the battery in a static situation,” he said.
For now, Professor Marco and his research unit will be focusing on further developments to the energy storage systems, as well as initial testing in remote locations. If successful, Jaguar could end up joining other carmakers such as Rivian, which has also expressed its intention to repurpose its vehicles’ retired batteries as energy storage devices.
Just last June, Rivian announced that it will be utilizing its old 135 kWh battery packs from its development vehicles as stationary energy units in a microgrid project in Adjuntas, Puerto Rico. In a press release, Rivian CEO RJ Scaringe noted that “second-life” batteries are a key factor in the adoption of electric vehicles and renewable energy.
“Second-life batteries are a big enabler to accelerating widespread adoption of renewable energy, and it’s exciting to envision this system contributing importantly to a community. This project allows us to model a customized energy storage solution that takes into account space constraints, disaster resiliency, and energy independence,” Scaringe said.

Tesla bear Guggenheim sees nearly 50% drop off in stock price in new note
Tesla bear Guggenheim does not see any upside in Robotaxi.

Tesla bear Guggenheim is still among the biggest non-believers in the company’s overall mission and its devotion to solving self-driving.
In a new note to investors on Thursday, analyst Ronald Jewsikow reiterated his price target of $175, a nearly 50 percent drop off, with a ‘Sell’ rating, all based on skepticism regarding Tesla’s execution of the Robotaxi platform.
A few days ago, Tesla CEO Elon Musk said the company’s Robotaxi platform would open to the public in September, offering driverless rides to anyone in the Austin area within its geofence, which is roughly 90 square miles large.
Tesla CEO Elon Musk confirms Robotaxi is opening to the public: here’s when
However, Jewsikow’s skepticism regarding this timeline has to do with what’s going on inside of the vehicles. The analyst was willing to give props to Robotaxi, saying that Musk’s estimation of a September public launch would be a “key step” in offering the service to a broader population.
Where Jewsikow’s real issue lies is with Tesla’s lack of transparency on the Safety Monitors, and how bulls are willing to overlook their importance.
Much of this bullish mentality comes from the fact that the Monitors are not sitting in the driver’s seat, and they don’t have anything to do with the overall operation of the vehicle.
Musk also said last month that reducing Safety Monitors could come “in a month or two.”
Instead, they’re just there to make sure everything runs smoothly.
Jewsikow said:
“While safety drivers will remain, and no timeline has been provided for their removal, bulls have been willing to overlook the optics of safety drivers in TSLA vehicles, and we see no reason why that would change now.”
He also commented on Musk’s recent indication that Tesla was working on a 10x parameter count that could help make Full Self-Driving even more accurate. It could be one of the pieces to Tesla solving autonomy.
Jewsikow added:
“Perhaps most importantly for investors bullish on TSLA for the fleet of potential FSD-enabled vehicles today, the 10x higher parameter count will be able to run on the current generation of FSD hardware and inference compute.”

Tesla Model 3 hits quarter million miles with original battery and motor
The Model 3’s Battery Management System (BMS) shows a State of Health between 88% and 90%.

A Western Australian Tesla Model 3 has captured global attention after racking up an impressive 410,000 kilometers (254,000 miles) on its original battery and motor, while still retaining around 90% of its original battery health.
Long-term Model 3
The 2021 Model 3 Standard Plus, equipped with a 60 kWh lithium iron phosphate (LFP) battery, has been in constant use as an Uber rideshare vehicle. According to Port Kennedy EV specialist EV Workz, the car’s Battery Management System (BMS) shows a State of Health between 88% and 90%.
EV Workz owner Edi Gutmanis shared the findings on Facebook’s Electric Vehicles For Australia page on August 8, and the post quickly went viral. As per Gutmanis, the Model 3’s charging history shows 15,556 kWh delivered via DC fast charging (29% of the total) and 38,012 kWh via AC charging (71% of the total).
Gutmanis also broke down the fuel savings for the Model 3. A petrol car covering the same 410,000 km at 7L/100km and $1.70 per liter would cost an estimated AU$50,000 in fuel. By comparison, charging the Tesla using average commercial rates would be about AU$20,737 and just AU$13,000 if using Western Australia’s EV tariff. That’s a potential refueling saving of roughly $37,000, not including the avoided maintenance costs of an internal combustion engine.
Simple fix
The car came into EV Workz for a driveline “judder” issue, as per a report form EV Central Australia. Gutmanis found the real cause was simply worn motor mount bushes. After seven hours of labor and $130 in parts, “the car drives just as good as the first day it left the dealership,” Gutmanis said.
Gutmanis, whose business also performs EV conversions on classics and 4x4s, says the results aren’t surprising. “We expect this sort of longevity with EV batteries,” he explained, though this is the highest-mileage Model 3 he has encountered in Australia.

Mysterious covered Tesla Model Y fleet spotted in Giga Berlin
The vehicles were sighted during a recent drone flyover of the Germany-based Model Y production site.

A fleet of mysterious covered Model Y units has been spotted at the Giga Berlin complex. The vehicles were sighted during a recent drone flyover of the Germany-based Model Y production site.
A mysterious fleet
The mysterious Model Y fleet was sighted by longtime Giga Berlin watcher Tobias Lindh, who has been chronicling the progress and activities of Tesla’s German factory complex for years. During his flyover on August 12, 2025, Lindh noted that he was able to spot a fleet of fully covered Model Y units being gathered in one section of the Giga Berlin site.
The presence of the covered Model Y units caught a lot of attention online, with numerous Tesla watchers speculating if the vehicles were the Model Y L or the yet-to-be-released Model Y Performance. Giga Berlin only produces Model Y units, after all, and both the Model Y L and Model Y Performance are yet to be rolled out by the electric vehicle maker.
Tesla Model Y Performance the Model Y L
The Model Y is Tesla’s best-selling vehicle by a mile, selling so well that it was able to become the world’s best-selling car by volume in 2023. With the changeover to the new Model Y this year, Tesla has only released the vehicle’s updated RWD and AWD versions. The updated Model Y Performance is yet to be released as of writing, though sightings of apparent Model Y Performance units have been reported on social media.
In recent weeks, however, the Model Y news cycle has been dominated by the upcoming release of the Model Y L, an extended wheelbase, six-seat version of the best-selling all-electric crossover. The Model Y L is expected to be produced in Giga Shanghai initially, though Giga Berlin, the Fremont Factory, and Giga Texas are also expected to produce the variant in the near future.
Check out Giga Berlin’s mysterious Model Y fleet in the video below.
