Tesla proudly hides ‘Octovalve’ insignia in Model Y, hints at next-gen thermal system
A number of the Tesla Model Y’s secrets are now coming to the surface, as auto veteran and teardown expert Sandy Munro continues his disassembly and analysis of the all-electric crossover. Among the most noteworthy of these secrets is the vehicle’s “Octovalve,” which could very well be an upgraded version of the Model 3’s unique “Superbottle,” which serves as the heart of the all-electric sedan’s thermal management system.
The Model 3 broke all conventions when it became evident that instead of using a different cooling system for the vehicle’s battery pack, cabin, and electronics, the all-electric sedan used one compact centralized thermal management system. Traditional automakers usually install several cooling systems in a car, since components are outsourced to different companies. Tesla opted for a different strategy with the Model 3, thanks to its vertically-integrated approach to its vehicles’ design.

Based on recent photographs taken by auto teardown expert Sandy Munro, the Model Y is also equipped with a novel thermal management system. But instead of a Superbottle, Tesla appears to have provided its latest vehicle with an “Octovalve” instead. Munro is yet to tear down and analyze the Octovalve, but just like its predecessor, it seems to be the heart of the Model Y’s cooling and heating system.
Interestingly enough, the use of the Octovalve instead of the Superbottle in the Model Y may be due to the all-electric crossover’s heat pump. Prior Teslas like the Model S, Model 3, and Model X have used electronic resistive heating systems, which are quick but less efficient than heat pumps.

This is speculation of course, but it appears that the Octovalve may be a novel way for Tesla to combine all heating and cooling systems in the Model Y in one unit. To make this possible, Tesla needed a customized, smart valve system that can perform all the cooling and heating tasks for the Model Y. Based on Munro’s previews, this definitely seems to be the case, as hinted at by the Octovalve’s own badge — an octopus with a snowflake on its head.
Elon Musk has mentioned the Octovalve in a previous tweet, while responding to a Tesla community member who inquired if the Model Y had a solution that is better than the Superbottle. Musk noted in his tweet that the Octovalve is pretty special on its own right, though he was quick to emphasize that all credit for the creation of the system is to the Tesla team, not himself.
“Yes. PCB design techniques applied to create a heat exchanger that is physically impossible by normal means. Heat pump also has a local heating loop to spool up fast & extend usable temperature range. Octavalve is pretty special too. Team did great work. No credit to me,” Musk wrote.
While discussing the Superbottle during the Model 3’s teardown, Sandy Munro stated that device, apart from giving serious technical and cost advantages for Tesla, is the very representation of the electric car maker’s vertical integration. By adopting such a device, Tesla pretty much saved on space, assembly costs, and final assembly time. Such is just not possible with other EVs such as the Chevy Bolt, an otherwise great electric car that utilizes three separate cooling systems.

“The Superbottle is a great example of how the normal automotive companies don’t work together, and Tesla does. That Superbottle crosses many lines that you can’t cross here (in Detroit). If I’m in charge of engine cooling or battery cooling, I don’t want nothing to do with cooling the cabin. And yet, we’ve got the motor cooling, the battery cooling, and electronics, all going through one little bottle that’s got some clever little ball valves that open and close to make sure that everything’s getting heated or everything’s being cooled to where it needs to be. We all thought that was the best thing in the whole damn car,” Munro commented.
Very little is known about the Octovalve and its actual functions for now, but if speculations are correct, it appears that Tesla has created something novel for its newest vehicle’s cooling and heating system once more. This bodes well for the company’s next vehicles as well, such as the Plaid Model S and Model X, the Cybertruck, the Semi, and the next-generation Roadster. Needless to say, it would be very interesting to see what vertically integrated solution Tesla creates for its next electric cars.

Tesla Megapacks chosen for 548 MWh energy storage project in Japan
Tesla plans to supply over 100 Megapack units to support a large stationary storage project in Japan, making it one of the country’s largest energy storage facilities.

Tesla’s Megapack grid-scale batteries have been selected to back an energy storage project in Japan, coming as the latest of the company’s continued deployment of the hardware.
As detailed in a report from Nikkei this week, Tesla plans to supply 142 Megapack units to support a 548 MWh storage project in Japan, set to become one of the country’s largest energy storage facilities. The project is being overseen by financial firm Orix, and it will be located at a facility Maibara in central Japan’s Shiga prefecture, and it aims to come online in early 2027.
The deal is just the latest of several Megapack deployments over the past few years, as the company continues to ramp production of the units. Tesla currently produces the Megapack at a facility in Lathrop, California, though the company also recently completed construction on its second so-called “Megafactory” in Shanghai China and is expected to begin production in the coming weeks.

Tesla’s production of the Megapack has been ramping up at the Lathrop facility since initially opening in 2022, and both this site and the Shanghai Megafactory are aiming to eventually reach a volume production of 10,000 Megapack units per year. The company surpassed its 10,000th Megapack unit produced at Lathrop in November.
During Tesla’s Q4 earnings call last week, CEO Elon Musk also said that the company is looking to construct a third Megafactory, though he did not disclose where.
Last year, Tesla Energy also had record deployments of its Megapack and Powerwall home batteries with a total of 31.4 GWh of energy products deployed for a 114-percent increase from 2023.
Other recently deployed or announced Megapack projects include a massive 600 MW/1,600 MWh facility in Melbourne, a 75 MW/300 MWh energy storage site in Belgium, and a 228 MW/912 MWh storage project in Chile, along with many others still.

Elon Musk responds to Ontario canceling $100M Starlink deal amid tariff drama
Ontario Premier Doug Ford said, opens new tab on February 3 that he was “ripping up” his province’s CA$100 million agreement with Starlink in response to the U.S. imposing tariffs on Canadian goods.

Elon Musk company SpaceX is set to lose a $100 million deal with the Canadian province of Ontario following a response to the Trump administration’s decision to apply 25 percent tariffs to the country.
Starlink, a satellite-based internet service launched by the Musk entity SpaceX, will lose a $100 million deal it had with Ontario, Premier Doug Ford announced today.
Starting today and until U.S. tariffs are removed, Ontario is banning American companies from provincial contracts.
Every year, the Ontario government and its agencies spend $30 billion on procurement, alongside our $200 billion plan to build Ontario. U.S.-based businesses will…

Ford said on X today that Ontario is banning American companies from provincial contracts:
“We’ll be ripping up the province’s contract with Starlink. Ontario won’t do business with people hellbent on destroying our economy. Canada didn’t start this fight with the U.S., but you better believe we’re ready to win it.”
It is a blow to the citizens of the province more than anything, as the Starlink internet constellation has provided people in rural areas across the globe stable and reliable access for several years.
Musk responded in simple terms, stating, “Oh well.”
Oh well https://t.co/1jpMu55T6s
— Elon Musk (@elonmusk) February 3, 2025
It seems Musk is less than enthused about the fact that Starlink is being eliminated from the province, but it does not seem like all that big of a blow either.
As previously mentioned, this impacts citizens more than Starlink itself, which has established itself as a main player in reliable internet access. Starlink has signed several contracts with various airlines and maritime companies.
It is also expanding to new territories across the globe on an almost daily basis.
With Mexico already working to avoid the tariff situation with the United States, it will be interesting to see if Canada does the same.
The two have shared a pleasant relationship, but President Trump is putting his foot down in terms of what comes across the border, which could impact Americans in the short term.
