Tesla “Battery Day” event date is looking like April 2020, says Elon Musk
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.
There are a lot of Tesla bulls out there who have astronomical expectations for the company, especially as its arm of reach has gone well past automotive and energy and entered artificial intelligence and robotics.
However, some of the most bullish Tesla investors believe the company could become worth $100 trillion, and CEO Elon Musk does not believe that number is completely out of the question, even if it sounds almost ridiculous.
To put that number into perspective, the top ten most valuable companies in the world — NVIDIA, Apple, Alphabet, Microsoft, Amazon, TSMC, Meta, Saudi Aramco, Broadcom, and Tesla — are worth roughly $26 trillion.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
Cathie Wood of ARK Invest believes the number is reasonable considering Tesla’s long-reaching industry ambitions:
“…in the world of AI, what do you have to have to win? You have to have proprietary data, and think about all the proprietary data he has, different kinds of proprietary data. Tesla, the language of the road; Neuralink, multiomics data; nobody else has that data. X, nobody else has that data either. I could see $100 trillion. I think it’s going to happen because of convergence. I think Tesla is the leading candidate [for $100 trillion] for the reason I just said.”
Musk said late last year that all of his companies seem to be “heading toward convergence,” and it’s started to come to fruition. Tesla invested in xAI, as revealed in its Q4 Earnings Shareholder Deck, and SpaceX recently acquired xAI, marking the first step in the potential for a massive umbrella of companies under Musk’s watch.

Now that it is happening, it seems Musk is even more enthusiastic about a massive valuation that would swell to nearly four-times the value of the top ten most valuable companies in the world currently, as he said on X, the idea of a $100 trillion valuation is “not impossible.”

Tesla is not just a car company. With its many projects, including the launch of Robotaxi, the progress of the Optimus robot, and its AI ambitions, it has the potential to continue gaining value at an accelerating rate.
Musk’s comments show his confidence in Tesla’s numerous projects, especially as some begin to mature and some head toward their initial stages.

Celebrating SpaceX’s Falcon Heavy Tesla Roadster launch, seven years later (Op-Ed)
Seven years later, the question is no longer “What if this works?” It’s “How far does this go?”
When Falcon Heavy lifted off in February 2018 with Elon Musk’s personal Tesla Roadster as its payload, SpaceX was at a much different place. So was Tesla. It was unclear whether Falcon Heavy was feasible at all, and Tesla was in the depths of Model 3 production hell.
At the time, Tesla’s market capitalization hovered around $55–60 billion, an amount critics argued was already grossly overvalued. SpaceX, on the other hand, was an aggressive private launch provider known for taking risks that traditional aerospace companies avoided.
The Roadster launch was bold by design. Falcon Heavy’s maiden mission carried no paying payload, no government satellite, just a car drifting past Earth with David Bowie playing in the background. To many, it looked like a stunt. For Elon Musk and the SpaceX team, it was a bold statement: there should be some things in the world that simply inspire people.
Inspire it did, and seven years later, SpaceX and Tesla’s results speak for themselves.
Today, Tesla is the world’s most valuable automaker, with a market capitalization of roughly $1.54 trillion. The Model Y has become the best-selling car in the world by volume for three consecutive years, a scenario that would have sounded insane in 2018. Tesla has also pushed autonomy to a point where its vehicles can navigate complex real-world environments using vision alone.
And then there is Optimus. What began as a literal man in a suit has evolved into a humanoid robot program that Musk now describes as potential Von Neumann machines: systems capable of building civilizations beyond Earth. Whether that vision takes decades or less, one thing is evident: Tesla is no longer just a car company. It is positioning itself at the intersection of AI, robotics, and manufacturing.
SpaceX’s trajectory has been just as dramatic.
The Falcon 9 has become the undisputed workhorse of the global launch industry, having completed more than 600 missions to date. Of those, SpaceX has successfully landed a Falcon booster more than 560 times. The Falcon 9 flies more often than all other active launch vehicles combined, routinely lifting off multiple times per week.
Falcon 9 has ferried astronauts to and from the International Space Station via Crew Dragon, restored U.S. human spaceflight capability, and even stepped in to safely return NASA astronauts Butch Wilmore and Suni Williams when circumstances demanded it.
Starlink, once a controversial idea, now dominates the satellite communications industry, providing broadband connectivity across the globe and reshaping how space-based networks are deployed. SpaceX itself, following its merger with xAI, is now valued at roughly $1.25 trillion and is widely expected to pursue what could become the largest IPO in history.
And then there is Starship, Elon Musk’s fully reusable launch system designed not just to reach orbit, but to make humans multiplanetary. In 2018, the idea was still aspirational. Today, it is under active development, flight-tested in public view, and central to NASA’s future lunar plans.
In hindsight, Falcon Heavy’s maiden flight with Elon Musk’s personal Tesla Roadster was never really about a car in space. It was a signal that SpaceX and Tesla were willing to think bigger, move faster, and accept risks others wouldn’t.
The Roadster is still out there, orbiting the Sun. Seven years later, the question is no longer “What if this works?” It’s “How far does this go?”

Tesla launches Cybertruck vehicle-to-grid program in Texas
The initiative was announced by the official Tesla Energy account on social media platform X.
Tesla has launched a vehicle-to-grid (V2G) program in Texas, allowing eligible Cybertruck owners to send energy back to the grid during high-demand events and receive compensation on their utility bills.
The initiative, dubbed Powershare Grid Support, was announced by the official Tesla Energy account on social media platform X.
Texas’ Cybertruck V2G program
In its post on X, Tesla Energy confirmed that vehicle-to-grid functionality is “coming soon,” starting with select Texas markets. Under the new Powershare Grid Support program, owners of the Cybertruck equipped with Powershare home backup hardware can opt in through the Tesla app and participate in short-notice grid stress events.
During these events, the Cybertruck automatically discharges excess energy back to the grid, supporting local utilities such as CenterPoint Energy and Oncor. In return, participants receive compensation in the form of bill credits. Tesla noted that the program is currently invitation-only as part of an early adopter rollout.
The launch builds on the Cybertruck’s existing Powershare capability, which allows the vehicle to provide up to 11.5 kW of power for home backup. Tesla added that the program is expected to expand to California next, with eligibility tied to utilities such as PG&E, SCE, and SDG&E.
Powershare Grid Support
To participate in Texas, Cybertruck owners must live in areas served by CenterPoint Energy or Oncor, have Powershare equipment installed, enroll in the Tesla Electric Drive plan, and opt in through the Tesla app. Once enrolled, vehicles would be able to contribute power during high-demand events, helping stabilize the grid.
Tesla noted that events may occur with little notice, so participants are encouraged to keep their Cybertrucks plugged in when at home and to manage their discharge limits based on personal needs. Compensation varies depending on the electricity plan, similar to how Powerwall owners in some regions have earned substantial credits by participating in Virtual Power Plant (VPP) programs.
