Tesla “Battery Day” event date is looking like April 2020, says Elon Musk

Published

on

Tesla CEO Elon Musk said the company is preparing to host a Battery Day for shareholders sometime after the first quarter, possibly in April. The announcement came during the earnings call following Tesla’s release of its Q4 2019 Update Letter.

Responding to a question from a participating investor about where Tesla stands in growing its battery capacity, Musk said that the company has already demonstrated massive improvement in growing the capacity of the cells, modules, and batteries it uses for its all-electric vehicles.

The CEO attributed part of the improvements to Tesla’s relationships with various battery partners, such as Panasonic, which is Tesla’s in-house supplier of lithium-ion batteries at Giga Nevada. Tesla also teamed up with other partners such as LG and CATL to produce battery packs for its cars produced in China. Aside from that, Musk declined to provide additional details on future plans for improving its battery technology, leaving investors to look forward to the upcoming Battery Day event later this year.

“We have a lot more to talk about this in detail in Battery Day probably April. We have a very compelling strategy. I mean, we are super deep in cell. Super deep. Cell through battery,” he said.

Tesla’s efforts to upgrade its batteries include the acquisition of California-based energy storage firm Maxwell Technologies, which was completed in May last year. Tesla’s interest in Maxwell primarily lies in the latter’s innovations in ultracapacitors and dry electrode technologies, which could potentially improve the company’s batteries.

Prior to the acquisition, Tesla also submitted a patent for an idea to use electrolyte additives to improve the performance and lengthen the lifespan of lithium-ion cells. The patent, titled “Dioxazolones and Nitrile Sulfites as Electrolyte Additives for Lithium-ion Batteries,” provided details on how Tesla can significantly increase the lifespan and performance of its batteries by adding electrolyte additives such as lithium salt. Tesla also submitted another patent for using cold plates and heat pipes to reduce heat generated by the battery, thereby increasing the longevity of its energy storage systems.

The latest developments appear to be moving Tesla toward the completion of a 1-million mile battery. In April last year, Musk said that Tesla owners will soon be able to drive their cars for up to 1 million miles over the lifespan of their vehicles. This is equivalent to 20 years if the cells are used for energy storage systems. Tesla lead researcher Jeff Dahn and a team from the Dalhousie University physics and atmospheric science department have also developed pouch cells that can last 1 million miles or 20 years in a grid storage system.

Tesla’s huge lead in the electric vehicle market is due in part to its constant efforts to improve its battery technology. In fact, its batteries have improved so much over the years that the Model S is nearing a range of 400 miles. The published range for the luxury sedan is 373 miles, but Musk said during the earnings call that the actual range is somewhere in the 380s.

“S and X actually have more range than we are currently stating on the website. We just haven’t gotten around to updating the EPA […] number, but the actual range of the Model S and X are above what the website says they are,” he said. “Somewhere in the 380s, something like that.”

He also added that the 18650 lithium-ion cells that power the Model S and X have largely improved over the years, adding that further developments could raise the range of the Model S to 400 miles.

“I think we’re pretty happy with the energy content of the cell and the improvements in the efficiency of the vehicle,” he said. “We’re rapidly approaching a 400-mile range for the Model S, for example.”

Battery Day is expected to be similar to Autonomy Day, which was held in April last year. The event, which was attended by investors and also available via livestream, was a full three-hour technical discussion of Tesla’s work on autonomous driving technology and how the company plans to achieve its goal of delivering fully self-driving cars.

Investor's Corner

SpaceX’s biggest earnings test yet lands Tuesday, and Tesla shareholders should be watching

SpaceX reports earnings Tuesday as Wall Street watches AI spending, Starlink growth and Tesla merger

Published

on

By

SpaceX reports third quarter results after the market closes Tuesday, with a webcast at 4:30 p.m. ET streamed on X, and Tesla follows a day later. Bloomberg consensus, cited by Pepperstone, calls for revenue of $12.89 billion, adjusted EBITDA of $6.62 billion and adjusted EPS near $0.15. That would be about 65% growth from the second quarter and SpaceX’s first profitable quarter since its IPO. Analysts expect roughly $6.4 billion from AI and $4.9 billion from Starlink, which is projected to reach 14.3 million consumer subscribers. Capital spending is forecast at $19.6 billion, leaving free cash flow near negative $11.6 billion.

The numbers matter because SpaceX has spent months trying to win over a skeptical market. It priced its record IPO at $135, spiked to $225.64, then sank near $105 in early August. Friday’s close of $146.03 sits about 28% below the June high. The Q2 report beat on revenue at $7.8 billion and put Starlink at 12 million subscribers, but $18.4 billion of capex hurt the stock. Since then SpaceX reached orbit on Starship Flight 14 with 26 Starlink V3 satellites, agreed to buy 800 MHz spectrum for about $8 billion as part of its Starlink Mobile push, and signed a fourth compute hosting deal in four months worth roughly $13 billion a year from December. Management is targeting more than 2 gigawatts of compute by year end and a $100 billion annualized revenue run rate. Evercore ISI, which raised its target to $275, said the quarter may be judged more on those targets than the reported figures

All of this sits under the Tesla merger question. Barclays analyst Dan Levy expects an all stock deal in which SpaceX buys Tesla at a premium, using reference values of $2.1 trillion and $1.5 trillion, and said an announcement would need to come by late October or early November to be voted on at Tesla’s December 6 annual meeting. Barclays estimates Musk would hold about 37% of the combined company and 56% of the votes. Musk said in July that combining companies cannot be discussed on an earnings call, but an investor question asking when SpaceX will merge with Tesla is sitting on SpaceX’s Q&A platform, and Teslarati has tracked how the Roadster demo revived the talk.

If a deal happens, Tuesday’s result would effectively set the price Tesla holders would receive. Their shares would convert into SpaceX stock, along with exposure to a company with a heavy investment on AI, while Tesla itself expects 2026 capex above $25 billion. A strong quarter and calmer spending would make that exchange easier to sell. Another round of heavy capex and a falling stock would make it harder.

SpaceX’s Gwynne Shotwell just made a quiet gesture toward Tesla

SpaceX president Gwynne Shotwell quietly followed Tesla on X, and merger watchers noticed right away.

Published

SpaceX President and COO Gwynne Shotwell has started following Tesla’s official account on X, a small change that landed in the middle of a very loud merger conversation. Whole Mars Catalog joked about it on Sunday.

A follow is not an announcement, and neither company has said anything about a deal. What gives the moment weight is the timing. Barclays analyst Dan Levy has told clients that an agreement could come before Tesla’s annual meeting, which must be held by December 6, with SpaceX as the buyer in an all stock deal, as we reported after the Roadster unveiling. Wedbush’s Dan Ives has stuck with a 2027 timeline.

Shotwell is the executive most worth watching if the two companies do move closer. When Musk was asked at the All In Summit why Tesla and SpaceX remain separate, Shotwell sat next to him and said SpaceX personnel had already moved into xAI to fill leadership and engineering gaps. The businesses were integrating “faster than I thought,” she said, though “not fully integrated yet.” Her responsibilities have also grown since SpaceX absorbed xAI, and she now oversees operations that include Grok and the company’s AI compute buildout.

The financial links are already there. Tesla’s $2 billion xAI investment turned into a stake of less than one percent in SpaceX, the two share the Terafab chip project in Austin, and Musk exercised his 2018 Tesla options a week after SpaceX began trading, a sequence analysts flagged as giving SpaceX public shares to use in a deal. Musk holds about 20 percent of Tesla and controls 85.1 percent of SpaceX’s voting power, according to our earlier breakdown.

The next test is close at hand. SpaceX reports its second earnings as a public company on Tuesday after the close, and Tesla follows on Wednesday. Musk told analysts in July that “we can’t talk about combining companies and that kind of thing on an earnings call,” so a direct answer is unlikely from either stage. Tesla shareholders can still submit and vote on questions through the Say portal until 4 p.m. EDT on Monday, and the merger is a recurring theme in the queue.

Tesla Roadster owners to get “Flying Stunt Mode” and looping track access

Musk says Roadster owners can command the unveiling stunts autonomously, with a Texas looping track.

Elon Musk says owners of the new Tesla Roadster will be able to ask the car to perform the stunts Tesla showed at its unveiling, with the car doing the driving itself. Musk made the comment Saturday in a reply on X to tech blogger Robert Scoble, and he added a promise of a looping track at Tesla’s Texas headquarters.

Scoble had argued that the person in the Roadster is not really driving it. In his description, the driver operates a computer that tells another computer what to do, with steering, braking and acceleration all handled by wire. Musk answered, “True. You will be able to ask the Roadster to perform any of the tricks shown autonomously, as it will be sentient. Also, we will have a wild looping track (crazier even than Hot Wheels) at our Texas HQ where you can test out your Roadster.”

At the October 15 event outside Waco, the car drove up a curved ramp until it was upside down, flew off on cold gas thrusters, flipped and landed. It also hovered over a Cybercab, Cybertruck, Semi, Model Y and Model 3 while moving. As we noted in our breakdown of the three Roadster configurations, Musk said at the event that the car “literally is just going to puff itself up” to perform the maneuvers whenever an owner wants. Saturday’s reply adds that the car would run them on its own.

Tesla has described some of the hardware that would make that possible. The Roadster uses steer by wire with a yoke, and its cold gas thrusters rely on electric actuators for small adjustments in flight. A fan system under the car creates suction, which Tesla says is strong enough to hold it upside down, a setup we covered in our look at the Roadster’s fan system and thrusters.

Musk did not say when an autonomous stunt feature might arrive, how it would work, or what he means by sentient. He also gave no size, location or opening date for the Texas track. Production is planned for Giga Texas in 2027 or 2028, and Tesla says the car is not approved for public road use. The Rocket version, the one built to fly, is invite only.

The comment follows a week of Musk teasing the event, including his claim that the demo would be a banger, which we covered before the stream. Tesla reports third quarter earnings on October 21, and shareholders can submit and vote on questions through the Say portal until 4 p.m. EDT on October 20, according to our earnings Q&A preview. A question about autonomous Roadster stunts and the Texas track would be a quick way to get specifics from management.
