Elon Musk posts Tesla Battery Day update, hints at mid-May event
Those who have been waiting for Tesla’s 2020 Battery Day will now have to wait a little longer. Tesla CEO Elon Musk announced that the event would “most likely” take place in mid-May, roughly one month after its originally intended date. “Hard to predict dates right now. Most likely postponed to mid May,” Musk wrote on Twitter as a response to a Tesla community member asking about the event.
The reason for the delay in the event seems to be related to the COVID-19 pandemic. This virus has halted production lines in Fremont and Buffalo and has caused the company to adapt to new delivery processes to deliver new electric cars to their customers. Considering that Tesla events usually involve presentations to groups of people, Battery Day may involve viewers being packed in a large room. Such does not conform to current social distancing suggestions to prevent the spread of the virus.
Tesla’s Battery Day will outline the company’s plans for battery development for future vehicles and energy solutions. Musk stated the event would be geared toward a review of Tesla’s cell chemistry, module and pack, architecture, and the company’s manufacturing plan that will detail how it can reach a terawatt-hour per year of battery production. “We have a very compelling strategy. I mean, we are super deep in cell. Super deep. Cell through battery,” Musk said.

Tesla’s ultimate goal with its cars is to reach price parity with its gas counterparts as soon as possible. Battery improvements would decrease the cost of vehicles tremendously, as the production of battery packs is one of the most expensive stages in EV manufacturing. Expectations suggest that Tesla has gotten its battery costs down to $100 per kWh, and Battery Day was widely speculated to be an event that discusses such a milestone.
Tesla has crafted a relationship with many cell manufacturers across the world, like Panasonic, which supplies the company’s lithium-ion vehicle batteries. In China, LG Chem and CATL are responsible for the task. The company has also made several acquisitions of battery research companies whose technologies can improve the quality of cells in the long term. One of these companies is Maxwell Technologies, whose research with ultracapacitors and dry electrode technologies could very well improve Tesla’s batteries in terms of quality and longevity.
This could lead to the development a “1-million mile battery,” which Tesla has predicted for its vehicles in the future. Researcher Jeff Dahn, a world-renowned battery specialist whose team at Dalhousie University, says that a battery capable of 1-million miles is more than feasible. This battery goal is attainable, especially considering the Dahn team’s development of pouch cells that have extended life.
Tesla held a similar event in 2019, called “Tesla Autonomy Day,” that outlined the company’s plans to complete its Full Self-Driving suite. However, it seems Tesla’s plans for 2020 are primarily focused on battery and energy storage, starting with Battery Day.
Fremont and Giga New York are poised to reopen on May 4, ending an over one-month shutdown. It is safe to assume that if this date is pushed back into late May or even early June, Battery Day could once again be delayed to ensure the safety of its attendees.
The Tesla Model X has always been one of the company’s most loved vehicles, despite its low sales figures, which can be attributed to its high price tag.
However, the Model X has been a signature item on Tesla’s menu of cars, most notably recognized by its Falcon Wing Doors, which are aware of its surroundings and open according to what’s around it.
But recent improvements to the Model X were looking slim to none, but it appears most of the fixes actually happened under the body, at least according to Tesla’s Vice President of Powertrain, Lars Moravy.
In a recent interview with Car and Driver, Moravy detailed all of the changes to the 2026 iteration of the vehicle, which was about 400 pounds lighter than it was originally. The biggest change is a modification with the rear motor, switching from an induction-type motor to a permanent-magnet design and optimizing the half-shafts, which shed about 100 pounds.
Tesla also got “almost 80 pounds out of the interior bits and pieces,” which “included making parts thinner, different manufacturing process choices, and incorporating airbag-deployment requirements into the headliner fabric,” the report said.
Additionally, the standard five-passenger, bench seat configuration saved 50 pounds by ditching pedestal mounting. This also helped with practicality, as it helped the seat fold flat. Engineers at Tesla also saved 44 pounds from the high-voltage wiring through optimizing the wiring from the charge-port DC/DC converter and switching from copper to aluminum wiring.

Tesla also simplified the cooling system by reducing the number of radiators. It also incorporated Nürburgring cooling requirements for the Plaid variant, which saved nearly 30 pounds.
Many Tesla fans will be familiar with the megacastings, manufactured in-house by presses from IDRA, which also saves more than 20 pounds and boosts torsional stiffness by around 10 percent. Tweaks to the suspension also saved 10 pounds.
People were truly disappointed with what Tesla did with the Model S and Model X, arguing that the cars needed a more severe exterior overhaul, which might be true. However, Tesla really did a lot to reduce the weight of the vehicle, which helps increase range and efficiency. According to Grok, every 200 pounds removed adds between 7 and 15 percent to range estimations.
This makes sense considering the range estimations both increased by 7 percent from the Model X’s 2025 configuration to the 2026 builds. Range increased on the All-Wheel-Drive trim from 329 miles to 352 miles, while the Plaid went from 314 miles to 335 miles.
Tesla has officially launched its first branded Supercharger just months after initiating a new program that allows third-party companies to brand their own charging piles.
The site opened in Land O’ Lakes, Florida, and features eight V4 Supercharging stalls offering up to 325 kW of charging speed. It appears it was purchased by a company called Suncoast Credit Union. This particular branch is located Northeast of Tampa, which is on the Gulf of Mexico.
It features graphics of Florida animals, like alligators:

Tesla launched this program back in September, and it basically was a way to expand its Supercharger presence and also allow companies to pay for the infrastructure. Tesla maintains it. When it announced the “Supercharger for Business,” it said:
“Purchase and install Superchargers at your business. Superchargers are compatible with all electric vehicles, bringing EV drivers to your business by offering convenient, reliable charging.”
The program does a few things. Initially, it expands EV charging infrastructure and makes charging solutions more readily available for drivers. It can also attract people to those businesses specifically.

The chargers can also be branded with any logo that the business chooses, which makes them more personalized and also acts as an advertisement.
The best part is that the customers do not have to maintain anything about the Supercharger. Tesla still takes care of it and resolves any issues:
“We treat your site like we treat our sites. By providing you with a full-service package that includes network operations, preventative maintenance, and driver support, we’re able to guarantee 97% uptime–the highest in the industry.”
It appears the Superchargers will also appear within the in-car nav during routing, so they’ll be publicly available to anyone who needs to use them. They are still available to all EVs that have worked with Tesla to utilize its infrastructure, and they are not restricted to people who are only visiting the business.
Tesla has revealed its Cybertruck light bar installation fix after a recall exposed a serious issue with the accessory.
Tesla and the National Highway Traffic Safety Administration (NHTSA) initiated a recall of 6,197 Cybertrucks back in October to resolve an issue with the Cybertruck light bar accessory. It was an issue with the adhesive that was provided by a Romanian company called Hella Romania S.R.L.
Tesla recalls 6,197 Cybertrucks for light bar adhesive issue
The issue was with the primer quality, as the recall report from the NHTSA had stated the light bar had “inadvertently attached to the windshield using the incorrect surface primer.”
Instead of trying to adhere the light bar to the Cybertruck with an adhesive, Tesla is now going to attach it with a bracketing system, which will physically mount it to the vehicle instead of relying on adhesive strips or glue.
Tesla outlines this in its new Service Bulletin, labeled SB-25-90-001, (spotted by Not a Tesla App) where it shows the light bar will be remounted more securely:
The entire process will take a few hours, but it can be completed by the Mobile Service techs, so if you have a Cybertruck that needs a light bar adjustment, it can be done without taking the vehicle to the Service Center for repair.
However, the repair will only happen if there is no delamination or damage present; then Tesla could “retrofit the service-installed optional off-road light bar accessory with a positive mechanical attachment.”
The company said it would repair the light bar at no charge to customers. The light bar issue was one that did not result in any accidents or injuries, according to the NHTSA’s report.
This was the third recall on Cybertruck this year, as one was highlighted in March for exterior trim panels detaching during operation. Another had to do with front parking lights being too bright, which was fixed with an Over-the-Air update last month.
