Tesla’s liquid-cooled charging connector patent paves way for the Semi’s Megachargers
A recently published patent application from Tesla suggests that the electric car maker is continuing in its efforts to improve its already-stellar Supercharger Network. The design outlined in the document, which features a liquid-cooled charging connector, can potentially pave the way for a more ambitious charging infrastructure, perhaps one that can specifically cater to the all-electric Semi’s Megacharger Network.
During the all-electric truck’s unveiling, CEO Elon Musk mentioned that the Semi will be able to replenish as much as 400 miles of range in as little as 30 minutes thanks to a network of Megachargers. Neither Musk nor Tesla provided the specs of the Megacharger during the vehicle’s unveiling, though speculations were high that network might provide a power output that is several times more powerful than the company’s Supercharger V2 Network, which had an output of around 120 kW then (Supercharger V2 stations have since been improved to 150 kW).
Being a large vehicle, the Semi requires a lot of power for its charging needs, involving the rapid transfer of mass amounts of electricity in a very short period of time without encountering any heating issues. This is a key concept outlined by Tesla in its recently published patent, titled “Liquid-Cooled Charging Connector,” which involves the use of a liquid cooling system on a charging connector itself. Tesla describes its concept in the discussion below.
“To transfer energy faster and decrease charging times, the cable and charging connector must be capable of withstanding high current loads. Current charging connectors are limited in the current loads that they can support as their ability to dissipate heat is limited. Thus, there is a need for a new charging connector to solve the aforementioned problems.
“The present disclosure related to a new charging connector. The charging connector has a first electrical socket and a second electrical socket. A first sleeve is concentrically coupled to the first electrical socket and a second sleeve is concentrically coupled to the second electrical socket. A manifold assembly encloses the first and second electrical sockets and the first and second sleeves, such that the first and second sleeves and manifold assembly create a hollow interior space there between. The manifold assembly has an inlet conduit and an outlet conduit such that inlet conduit, interior space, and outlet conduit together create a fluid flow path.
“Cooling fluid flows through the fluid flow path and cools the charging connector. During operation, the cooling fluid bifurcates into a first fluid stream which flows around the first sleeve, and a second fluid stream which flows around the second sleeve. The first and second fluid streams combine upstream of the outlet conduit. The first sleeve encloses the first electrical socket, and the second sleeve encloses the second electrical socket. The cooling sleeves are made from a thermally conducting material such that heat generated by electrical sockets can be removed by the cooling fluid. In embodiments, this thermally conducting material is a thermally conductive plastic material.”
Tesla notes that its liquid-cooled supercharger connector does not only allow faster charging; it also makes the routing of wires in a charging connector much more efficient. This means that Tesla’s Supercharger connectors could eventually be smaller and more compact despite being capable of greater output. An example of this appears to be hinted at by Supercharger V3’s liquid-cooled cables, which are smaller and more compact than those used in Tesla’s V2 Network.
“Cooling fluid absorbs thermal energy from heat in the electrical sockets 404, 406. Sleeves 410, 412 are made of a thermally conducting, electrically insulating material. Heat from the electrical sockets 404, 406 is transferred to cooling fluid through sleeves 410, 412. After flowing around hollow interior space 416, the first fluid stream 804 and the second fluid stream 806 combine together upstream of outlet conduit 514 and flow outside of manifold assembly 414 through outlet conduit 514. Cooling fluid flowing out of manifold assembly 414 through outlet conduit 514 may be received by a reservoir (not shown) which may provide for heat exchanging arrangements. A heat exchanger may be provided to take away heat absorbed by cooling fluid. After rejecting absorbed heat, the cooling fluid may be recirculated back to inlet conduit 512 for further cooling of charging connector 210.
“FIG. 9 shows another component included by charging connector 210. A Printed Circuit Board Assembly (PCBA) 902 is thermally coupled to charging connector 210. In embodiments, PCBA 902 is a two-part structure. A first part of PCBA 904 is coupled to charging connector 210 such that the first part of PCBA 904 sits on top of electrical sockets 404, 406. A second part of PCBA 908 is connected to the first part of PCBA 904 through a rigid-flex PCB construction, or other similar interconnects. The two-part structure of PCB A 902 allows for a more efficient routing of electrical wires of charging connector 210, and overall size of charging connector 210 may be conveniently reduced.”
Tesla’s Superchargers are among the fastest and most expansive electric vehicle charging infrastructures in the auto industry. In keeping with its spirit, the company has made it a point to never stop innovating, as exhibited by the company’s debut and ongoing ramp of its Supercharger V3 Network. This could ultimately pay off for Tesla, whose lead in the electric vehicle race might potentially increase even more.
Such innovations appear to be required of the company, especially with the rollout of ambitious EVs such as the Semi, a vehicle with a different charging infrastructure compared to Tesla’s existing lineup of electric cars. That being said, Tesla nevertheless deserves credit for pushing the envelope and staying on top of its innovations. In the electric vehicle race, after all, a liquid-cooled charging connector could end up making the difference between the fast-charging capabilities of the Tesla Semi and rivals from Daimler and Nikola.

Ferrari unveiled its Luce EV over the weekend, and so far, its reception has been an absolute disaster, gathering negative reactions from a wide variety of people, including former executives.
The stock even took a hit on its first day of trading following the unveiling, dropping over 7 percent at one point.
Ferrari moving to EVs from its traditional V12s and mid-engine sports cars is a massive move. It was designed by Sir Jony Ive and Marc Newsom’s LoveFrom studio, which is known for design work for tech giant Apple. “Luce” means “light” in Italian, so Ferrari drew inspiration for its name from its sleek design, characterized by a smooth, sculpted body with rounded edges.
But its reception has been far from what Ferrari expected. The overall design has drawn some harsh criticism since its reveal, and it is simply stunning that such a storied company, with a rich history of beautiful, powerful cars has revealed a design that many are not a fan of.
Ferrari unveiled its all-electric Luce over the weekend, and it has truly gotten some attention…not for the right reasons.
From an Italian legend that has built some beautiful cars in its history, this almost feels like a ploy to inevitably cancel its electric program. pic.twitter.com/rczSSb3pJx

Responses to the design were widely negative, with some saying, “Enzo is rolling in his grave,” and “This looks like a Nissan LEAF with a bad body kit.”
Former Ferrari Chairman Luca di Montezemolo said:
“If I said what I really think, I’d harm Ferrari. We’re risking the destruction of a myth, I’m very sorry about that. I hope they at least remove the Prancing Horse from that car.”
🚨 Luca di Montezemolo former Ferrari chairman reacts to the new electric Ferrari Luce:
“I’ve seen the project has already been delayed more than two years. I don’t like commenting from the stands—when I was in the game, it annoyed me when people did that. I think for now the… https://t.co/TzIDxFzHso

Ferrari has scaled back EV commitments in the past, primarily in response to weaker-than-expected demand for its electric powertrains.
Priced at roughly $640,000 in the U.S., it is tough to see how this car will ever truly live up to the massive expectations many had for it. It almost feels like, to a certain extent, Ferrari is looking for a way to get out of building EVs.
Tesla unveiled a juicy new detail on the Roadster, its long-delayed supercar project, and additionally hinted at a new unveiling timeline, as it appears yet another month will pass without seeing the capabilities of the vehicle.
Vice President of Vehicle Engineering at Tesla, Lars Moravy, revealed on the Ride the Lightning podcast that the Roadster will be built at Gigafactory Texas, adding that “you’ll start to see a lot of things unfold in the next months.”
While we get a good detail on the plant of manufacture, we also get another letdown, as it appears the unveiling event will not take place in May, as CEO Elon Musk hinted during the Earnings Call.

The Roadster was first unveiled back in 2017, alongside the Semi, which entered production earlier this year. It was Tesla’s attempt at a true supercar; it would be rare, expensive, and lightning quick, among other incredible capabilities, like potentially hovering for a short period thanks to a collaboration project with SpaceX.
However, the vehicle was set to be delivered in 2020. Parts and supply chain issues due to the COVID-19 pandemic started these delays, and since then, Tesla, and specifically Musk, have wanted to push the capabilities of the Roadster to somewhere the human mind may not be able to currently comprehend.
Both Chief Designer Franz von Holzhausen and Moravy have said many things about the Roadster over the past few years, hinting that the car truly could be worth the wait. However, the continuous delays we’ve seen have undoubtedly been discouraging.
With that being said, it’s not like Tesla has been doing nothing. Instead, the company has been focusing on revamping current models, phasing out others, and working on developing the cars of the future, specifically, the Cybercab, which entered production at Giga Texas in April.
Despite the Roadster’s delays, there is still a ton of anticipation for the vehicle to be released. It will have a steering wheel, as Musk said it will be “the best of the last of the human-driven cars.”
NASA has filed a procurement notice announcing its intent to add six post-certification missions to SpaceX’s existing Commercial Crew Transportation Capability contract. The agency said it would order up to three of those missions immediately upon adding them to the contract, with the remaining three available as needed through the end of the International Space Station’s planned operations in 2030.
The reason for the expansion is straightforward. NASA cited recently shortened ISS mission durations, technical issues and schedule delays encountered by Boeing, the allocation of missions between Boeing and SpaceX, and the ongoing technical challenges of maintaining a reliable crew transportation capability as the driving factors behind the decision. Boeing’s CST-100 Starliner has still not been certified for crewed flights, and a cargo-only Starliner mission was not included on NASA’s most recent mission manifest. With Boeing effectively sidelined for the foreseeable future, SpaceX is the only American company capable of rotating crews to the station.
The history behind this contract tells the fuller story of how SpaceX got here. NASA originally awarded SpaceX its Commercial Crew contract in 2014 for $2.6 billion. In 2022 NASA modified the contract to add five missions covering Crew-10 through Crew-14, worth $1.436 billion, bringing the total contract value at that point to $4.9 billion. The recent May 18 filing by NASA extends that runway further, with Crew-12 currently docked at the station and Crew-13 assigned and targeting a mid-September 2026 launch.
According to a report by SpaceNews, NASA stated in its filing: “It is necessary to award additional PCMs to SpaceX given the recently shortened ISS mission durations, technical issues and schedule delays encountered by Boeing, the allocation of missions between Boeing and SpaceX, NASA’s projections for when an alternative crew transportation system may become available, and the ongoing technical challenges of maintaining a reliable capability for crewed flights to ISS.”
No dollar value for the new six missions has been publicly confirmed yet, but based on the 2022 precedent of roughly $287 million per mission, the new block could represent close to $1.7 billion in additional contract value. With SpaceX simultaneously preparing Starship as NASA’s Artemis lunar lander, filing its S-1 for a June IPO, and now absorbing more ISS crew rotation work, the company’s role as the primary contractor for American human spaceflight is no longer a matter of circumstance. It is NASA policy.
