Tesla’s new battery expert will do “whatever it takes” to improve battery performance

World renowned battery research Jeff Dahn will join forces with Tesla Motors on June 8. His mission is to do “whatever it takes” to improve the science behind the batteries Tesla relies on for its cars and energy storage devices.

Jeff Dahn is a world renowned battery researcher who teaches at Dalhousie University in Nova Scotia. According to the university’s website, he “is recognized as one of the pioneering developers of the lithium-ion battery that is now used worldwide in laptop computers and cell-phones. Dahn’s recent work has concentrated on the application of Combinatorial Materials Science methods to battery and fuel cell materials problems. He is the author of over 500 refereed journal papers and co-inventor of 58 inventions with patents issued or filed.”

Up until know, Dahn has been working exclusively doing research for 3M and the Natural Sciences and Engineering Research Council of Canada to develop longer-lasting, lower cost lithium-ion battery cells, but his agreement ends on June 7. On June 8, he will join forces with Tesla Motors and work exclusively for it. He says his mandate is to do “whatever it takes” to improve the company’s battery performance.

Dahn is a proponent of a different form of battery chemistry than Tesla currently uses. Called lithium nickel manganese cobalt oxide, or NMC, it has lower capacity than lithium cobalt batteries but higher specific power and longer life, according to Battery University. Elon Musk has publicly ridiculed NMC chemistry. Tesla is firmly committed to lithium nickel cobalt aluminum oxide chemistry, or NCA.

Does hiring Dahn indicate that Tesla may be considering a shift in its core battery technology? Dahn told Quartz recently that his mission at Tesla is the same as every other battery researcher in the world — low cost, high energy density, and long battery life. But “whatever it takes,” an operational mantra he said he picked up in conversation with Kurt Kelty, Telsa’s battery director, will be his rule. “Those are the goals, and that’s how we’re going to do it,” Dahn said. “We’re open to anything that makes sense.”

A willingness to consider all possible options is a characteristic that defines Elon Musk. It’s astonishing that Musk and Tesla would consider options that challenge the battery technology they have been committed to for years, but if that’s what it takes to keep Tesla ahead of the competition, that’s what they are prepared to do.

Tesla Model 3 filings in China show interesting hardware addition

The addition of a front bumper camera to the Tesla Model 3 is a big upgrade from a hardware perspective.

Tesla Model 3 filings in China are showing the vehicle could get a very interesting hardware addition, one that was not included on the “Highland” update when it rolled out to customers a year and a half ago.

The Model 3 Highland is Tesla’s updated version of the all-electric sedan, and was launched across the world in early 2024. It featured a variety of updates, including new exterior and interior designs.

However, there were a few things missing from the update that surprised Tesla fans because they were included on other cars.

One of them was the lack of a front bumper camera, a hardware piece that was included on other vehicles within the company’s lineup, including the Model Y Juniper, an updated version of the all-electric crossover that launched earlier this year.

Now, it seems Tesla is preparing to implement that front camera on the Model 3, as new filings with China’s Ministry of Industry and Information Technology (MIIT) showed the car with the addition:

The front bumper camera is a small but powerful addition to Tesla vehicles. It not only enhances visibility for simple tasks like parking, helping avoid things like curbs, but it also helps provide a wider field of view directly in front of the car.

It is also a crucial part of the Full Self-Driving and Autopilot suites, helping provide yet another angle of vision for the vehicle as Tesla makes its suite more robust. It is already improving through software upgrades and data collection, but it could always use additional hardware to enhance accuracy.

A Model 3 Highland test mule was spotted near Boston, Massachusetts, back in May with a variety of additional cameras equipped. Some believed this was a vehicle that was assisting with collecting training data.

Tesla is testing a Model 3 with some mysterious cameras in the U.S.

However, it could be a sign of Tesla planning to add this piece of hardware to a slightly updated version of the new Model 3 that could come to production in various markets in the near future.

Tesla CEO Elon Musk details massive FSD update set for September release

“This will substantially reduce the need for driver attention, but some complex intersections, heavy weather or unusual events will still require attention.”

Tesla CEO Elon Musk detailed the changes that are expected to come with a massive Full Self-Driving (FSD) update, which is set to roll out sometime in September, he revealed earlier this week.

Tesla has been refining its FSD suite for years, but it has never been as good as it is now. The focus is to get the suite to a point where interventions are no longer needed and drivers simply become passengers, as they will not be responsible for paying attention to the road.

Elon Musk teases crazy new Tesla FSD model: here’s when it’s coming

That version of FSD will come eventually, but not next month. However, there are dramatic improvements that will come with next month’s FSD update that will roll out to the public, Musk said:

“The FSD software update next month will be a major step-change improvement for rare conditions.”

Additionally, he provided specific details on what would change, hinting that the need for a driver to pay attention will be “substantially reduced,” but there are some “complex intersections, heavy weather, or unusual events” that will still require drivers to assume responsibility for the car:

“This will substantially reduce the need for driver attention, but some complex intersections, heavy weather or unusual events will still require attention.”

We have been teased about these types of updates before, but usually they involve some kind of mention of FSD being ready for unsupervised driving “by the end of the year.” Musk did not mention that here.

There is also the fact that Tesla has another FSD build in Austin for the Robotaxi suite that is more advanced than what is available to the public. It has performed well, Musk says, making claims that there are times when it feels “eerily human.”

The improvements in FSD capabilities in subsequent releases are usually very evident. As Tesla continues to refine the suite for the public, it gains more confidence and becomes smarter through the collection of data and the use of neural networks.

The only thing left to wait for is the release itself, and we are hopeful it will roll out to the public in September, as Musk says.

The specs of the upcoming Tesla Model Y L has appeared in new Chinese regulatory filings, revealing key specifications including a six-seat layout and an extended range of up to 751 kilometers. The variant is expected to launch later this year alongside a new long-range Model 3 variant rated at 830 kilometers.

The updates were listed on the China Ministry of Industry and Information Technology’s (MIIT) latest batch of new energy vehicle models that are eligible for vehicle purchase tax exemptions.

Model Y L to debut with larger battery, six-seat layout

Listed under the model code TSL6500BEVBA0, the Model Y L will feature dual motors producing 142 kW at the front and 198 kW at the rear. It will be powered by a 465-kilogram 82.0-kWh lithium-ion battery from LG Energy Solution, with a pack energy density of 176 Wh/kg, as noted in a CNEV Post report. The long-range crossover achieves 751 km on the lenient CLTC cycle, making it Tesla’s highest-range Model Y to date in China despite its curb weight of 2,088 kg.

The “L” designation is believed to refer to the vehicle’s larger size and seating configuration, as the new variant is listed with six seats. It builds on Tesla’s strategy to diversify offerings in the Model Y lineup, which currently includes both RWD and AWD five-seat versions.

Model 3+ breaks record with 830 km CLTC range

Alongside the Model Y L, Tesla China also registered a new rear-wheel-drive Model 3, which was designated with the model code TSL7000BEVBR1. The vehicle boasts either 800 or 830 km of range on the CLTC cycle, depending on its trim. This marks the highest range yet for any Tesla vehicle in China.

The variant will use a 448-kilogram, 78.4-kWh LG-supplied battery with an energy density of 175 Wh/kg and a peak motor output of 225 kW. The vehicle’s curb weight is listed at 1,760 kg. The model was previously identified in filings as “Model 3+,” hinting at a possible tier above the existing long-range variant, which tops out at 753 km CLTC.
