The United States Department of Energy announced that it will offer up to $45 million in funding to support the domestic development of advanced and more efficient electric vehicle batteries. The announcement comes just one day after the Biden Administration allocated over $3.1 billion to boost EV battery manufacturing in the United States.

“Advanced batteries are the heartbeat of the electric vehicle industry and investments to make them charge faster and last longer will be critical to accelerate the deployment of electric cars and trucks,” Jennifer Granholm, the U.S. Secretary of Energy said. “The benefits of an electrified transportation sector in America will be felt for generations to come — from directly combatting climate change to growing domestic manufacturing jobs and strengthening our overall energy independence.”

The DOE will fund the projects through the launch of the Electric Vehicles for American Low-Carbon Living (EVs4All) Program, which is made possible through the department’s Advanced Research Projects Agency-Energy. The plan is part of President Biden’s plan to have at least half of all passenger vehicle purchases be electric in the United States by 2030.

The EVs4All program will address three of the most heavily scrutinized portions of the EV ownership experience: Charging Speed, Efficiency, and Resilience.

Faster Charging: The DOE said that while at-home charging is preferred for many EV drivers as it can offer a fully-charged vehicle every morning, there are still issues with some owners who live in rented spaces or are in other situations where home charging is not necessarily possible. Advanced batteries are capable of safe, rapid charging that can eliminate the total time spent at a public EV stall. It will not only keep times at chargers to as little as five minutes, but it will also increase cost savings during each charge.

Increased Efficiency: Electric vehicle ranges can vary based on climate. Those who live in colder weather settings will tell you firsthand that they do not get the range they expected in their EVs. Current EV batteries lose performance when confronted with these situations, with some manufacturers using things like heat pumps to combat range loss. Developing new battery chemistries that will not be affected as much by cold temperatures is “key to ensuring batteries can power vehicles in the coldest parts of the country as well as motivating broader adoption amongst drivers who live in those regions,” the DOE said.

Improving Resilience: Range anxiety is one of the most common terms in the EV ownership experience. Battery resilience is needed to alleviate concerns from new EV owners, especially those who take long drives to work or for leisure. The DOE said this may be the most important thing to develop as two-thirds of Americans prefer the more economical option of purchasing used vehicles rather than leasing or buying new cars.

Elon Musk teases TSMC as potential Terafab partner

Published

Elon Musk has acknowledged that early discussions with Taiwan Semiconductor Manufacturing Company (TSMC) could bring the company into his ambitious Terafab semiconductor project, signaling a possible partnership with the world’s leading contract chipmaker.

Musk confirmed that early talks are underway, but as of right now, they are “just discussions.” There is no confirmation of a deal nor dismissal of the possibility of one, leaving open the prospect of one of the largest advanced-chip collaborations under discussion in the U.S.

The report that speculated on potential discussions between Terafab and TSMC comes from Tim Culpan, who outlined a few ways the collaboration could operate. One is TSMC using the project as an “anchor customer” for future facilities in Texas, potentially contributing process expertise, operational know-how, or capacity while Terafab provides capital, long-term purchase commitments, or both.

Tesla and SpaceX jointly developed the Terafab project, with Intel already participating on the tech side. Elon Musk announced the project in March, and it intends to produce more than one terawatt of AI compute capacity annually once fully built.

Elon Musk’s Terafab project locks up massive new partner

Company statements place the first phase at approximately $16.8 billion in cost, with later filings pointing to a total that could reach well into the tens of billions across multiple stages.

Intel joined the effort in April 2026 and is expected to supply its 14A manufacturing process for the full-scale plant.

Musk has said existing suppliers, including Samsung and TSMC, remain important for near-term needs; Tesla already has production arrangements with Samsung for AI5 and AI6 chips, but that future demand from Optimus robots, Cybercab vehicles, and planned space-based data centers will eventually exceed what the global industry can currently deliver.

Terafab is positioned as the long-term answer to that projected shortfall, and Tesla did something similar during COVID to avoid a chip shortage. This is just a much larger-scale solution.

If the partnership were to materialize, it would add TSMC’s industry-leading strategies to a project that already combines Tesla’s and SpaceX’s capital and offtake with Intel’s process technology. For now, the only public confirmation is Musk’s brief acknowledgement that conversations are occurring.

Tesla reveals early Robotaxi charging strategy, showing scrappy DNA

Tesla’s early strategy for charging units operating within its Robotaxi fleet reveals that the company surely has not lost any of that scrappy DNA that took it from an unlikely success story to the most valuable carmaker in the world.

An observer at a Tesla Supercharger in Austin spotted ten total Robotaxi vehicles arrive: one Cybercab and nine Model Y units. A Tesla employee was waiting at the lot and allowed each unit to park itself; every car that arrived had nobody in it.

It’s a very interesting strategy, but extremely understandable at this early point in the Robotaxi program. It’s only been out for about 15 months, and Cybercab just entered the fleet in early September.

On top of that, Tesla is still working tirelessly on its wireless charging apparatus, and a new patent was just published regarding that product last week.

However, this is just another example of how Tesla still has plenty of that scrappy DNA leftover from the “production hell” days, when CEO Elon Musk slept on the floor of the factory, employees were working crazy hours, Tesla was building Sprung Structures to build cars in, and the company was tiptoeing on the brink of bankruptcy.

For now, Tesla is utilizing a simple system for recharging its ride-hailing vehicles, and that is a Tesla employee doing it manually until another solution presents itself. Sure, it’s not the most high-tech thing, and it certainly is not what people might have expected at this point in time, but it works, and it’s keeping the entire suite running.

Tesla Robotaxi expands hours, Musk explains why it’s been a challenge

Tesla is expanding its Robotaxi service hours by pushing the time back by one hour, keeping the ride-hailing service operational until 11 p.m., one hour later than previously.

CEO Elon Musk confirmed the change and offered a specific reason the expansion has been gradual: the system still needs to reliably avoid small pets that are difficult to see after dark, as they commonly blend into the color of the road, especially when they’re grey.

The latest adjustment restores only a fraction of the operating window the service once held. When paid Robotaxi rides began in Austin on June 22, 2025, vehicles ran from 6 a.m. to midnight.

Tesla Robotaxi will be a 24/7 service: here’s when

In September 2025, Tesla lengthened the day to a 2 a.m. close, producing a 20-hour window that stayed in place for most of the following year. By early August of this year, the cutoff had already been pulled back; an August 26 update formalized hours of 6 a.m. to 10 p.m. across Austin and several other markets.

The October move to 11 p.m. therefore leaves the Austin day one hour shorter than the original launch schedule and three hours shorter than the 2025 peak.

Musk addressed the constraint directly after the announcement. “The main thing we’re trying to solve is making sure that we don’t run over pets when they’re hard to see at night,” he wrote. “Literally trying to avoid grey kittens on grey tarmac in the dark.”

The example points to a low-contrast perception problem in which a small animal can blend into the road surface under limited lighting.

Tesla’s vehicles rely on cameras and neural-network processing rather than lidar; Musk has previously argued that advanced vision software can extract useful information even in low light by analyzing photon counts, but the pet-detection case remains the stated limiter in later hours.

The modest schedule change arrives alongside faster growth in the purpose-built Cybercab fleet. Texas registration data tracked by observers showed the Austin Cybercab count rising sharply in recent weeks, reaching 169 vehicles after more than 100 were added in a short span.

Tesla has indicated that a broader shift toward 24-hour operation is tied to the upcoming FSD v15 software release expected this month on Robotaxi vehicles. Until that capability is validated for the edge cases Musk described, the company continues to add service time incrementally rather than jumping straight to overnight coverage.

The one-hour extension gives Austin riders a later option for evening trips while the underlying detection work continues.
