Tesla Wants To Use Liquid Fluid For Next-Gen Heated And Cooled Seats

Tesla has patented an innovative new way to heat and cool car seats, Car and Driver reports.

Heated and cooled seats aren’t a new invention. Usually, the heated function of a car seat works thanks to a host of resistors that heat up when an electric current is passed through them. Vehicles with cooled seats – that also require perforated upholstery – use fans to blow air out of the seat. Tesla thinks things can be done differently.

A patent from the electric car manufacturer reveals how heated and cooled seats could feature a layer of fluid under where an occupant sits that is surrounded by another layer to contain this fluid. Also found within this intermediate layer is a heating and cooling element as well as a small pump that sends the heated or cooled fluid around the seat.

The patent doesn’t describe what kind of fluid could be used but Car and Driver suggests it is most likely to be some kind of aqueous gel. It also remains to be seen what kind of element will be used to heat and cool the seat. Detailed in the patent are a number of measures to ensure the system wouldn’t spring a leak, including supports that ensure proper flow throughout the system.

No mention is made in the patent as to whether or not such a system will find its way into the production line but considering Tesla’s penchant for doing things a little differently, it certainly wouldn’t be a surprise to see such a system in Tesla vehicles in the future.

    “Liquid fluid”? I’m confused. Are there solid fluids?

    • Ciprian Rogoz

      Of course there is. Sand is a fluid. Flour also. But they are solids.

      • krusshall

        …can behave like a fluid is the more appropriate descriptor.

      • Nick

        No, sand is a solid. It may exhibit fluid-like characteristics under certain circumstances, but it is still a solid.

  • Reformed Alchemist

    They should design it to also be a fire suppression system….

    “Difficult to puncture” laugh out loud!!!

    These small gimmicks keep Tesla loyalist happy, but is it truly building their business advantage? At the moment, Tesla is the EV leader. Keep the innovation going on what brought you to the party. Stop worrying about videogames while parked, jelly seats and Netflix & Drive. I want to hear breakthroughs, such as “Tesla has the lightest EVs around and here’s how they did it.”

      Every small innovation is an innovation. I’m pretty sure they are thinking outside of the box to save energy for heating and cooling seats. Why would you accept the good old way when there could be better solutions? Seems like a very narrow minded thinking. Btw, the video games are great fun too, especially for kids, especially when it rains and you have to charge 30-40 minutes.

        Heated jelly seats may be nice, but what’s the cost of time and effort engineering them? Could that time, an asset, be used more effectively somewhere else that would be more meaningful to the brand. How much are those jelly seats going to cost in research and development hours?

        These small gimmicky features do pull people in, no doubt about that. However, they need to develop more meaningful innovations if they wish to stay in the EV elite for the next 10+ years. Engineering lighter EV models should be the number one goal of every EV maker. Tesla should be leading the charge on this front or more established brands might beat them to it.

      They do have the lightest EVs around. Compare a Model 3 Performance and a Taycan Turbo, which have similar sized interiors and performance. The Tesla weighs over 1000lbs less, uses a smaller battery, and still has considerably more range…and costs 1/3 the price.

      • Ben

        Comparing a Taycan to a model 3? C’mon now. You think they’re marketed to the same people? Do you believe their ethos is the same?

        • TheNovanglus

          They are very similar in size and very similar in performance. For $100k, you would think you would get more than just a nicer interior…like, maybe, lighter weight. Colin Chapman was noted for saying that to go faster, you should simplify and add lightness. For a sports car manufacturer, Porsche most certainly didn’t take that path.

          • Ben

            Again, both vehicles are targeted towards different people and have different ethos in mind when built. We can mismatch vehicles and compare them due to a few similarities, but that won’t hold water with the actual buying public.

            I’ve actually commented on the price gap of the Porsche and it’s actual competition, the Model S. I mentioned the best way to defeat a product/service juggernaut is to clip into their customer’s varied desires, not to take them head on. What this means is, Porsche is only apparently only aiming for the high end market, people who want something else other than Model S.

            In short, the Taycan isn’t going for Tesla Model S’ typical buyer, only the ones with fat bank accounts and/or desire to drive something exclusive. Economics shows us people won’t care about range or cabin space as long as they’re reasonable. Attributes such as exclusivity and brand appeal will play larger roles.

            Lastly, you and I both know the Taycan isn’t a sports car. Can it be sporty? Sure, but lets not act like Porsche doesn’t know the impact of weight savings in the name of performance.

          • TheNovanglus

            Look, dude, you’re going off topic. This what I responded to:

            “Engineering lighter EV models should be the number one goal of every EV maker. Tesla should be leading the charge on this front or more established brands might beat them to it.”

            I compared two models of comparable interior size and performance, while noting the Tesla was more than a 1000lbs lighter…and the other maker was a sports car maker who literally touted Porsche’s focus on light weight in its marketing, and even called the Taycan “the 911 of e-cars.”

            So, obviously Tesla IS leading the charge on light weight EVs. That is the point…Tesla built a car with equivalent performance and size to “the 911 of e-cars” that weighs over 1000lbs less without using exotic materials; consequently it can be purchased for 1/3 the price.

            Now, you can go on underling and bolding statements all you want, but those are the facts on the ground in the real world.

            I’m done with your fantastical argument. Have a good day.

          • Ben

            It seems like you took my highlighting of certain portions as an offensive or aggressive push of my opinion. In fact, I did it as a courtesy to you. I’m aware that you and I both have been typing a wall of text. Highlighting acts as a summary, tl;dr, of my opinion.

            You compared the Model 3 to the Taycan for examples of Tesla weight savings. I pointed out they’re not competing vehicles, but have a few similarities in capacity. Simple. Where the Model 3’s ethos is to be affordable and a family sedan, the Taycan is supposed to be an executive sport’s sedan with performance that is extremely reliable. This results in different weights.

            By comparing the weights of EV vs EV, its like comparing the weights of contestants of the Biggest Loser to determine who’s healthier. Tesla shouldn’t be competing with other EVs if they’re the leader, should they? Tesla should be focused on lower weight to be similar(or lower) to ICE vehicles. That was my point. Developing jelly seats doesn’t fix one of the biggest issues of EVs, weight.

    Maybe Tesla should use Paraffin? At least that way when their cars spontaneously combust, you’ll go out even quicker.

    Liquid fluid
    err, as apposed to what other type of fluid? 🤦‍♀️

    • Aeromann

      Yes solid fluid.

  • :/ Yurr

    Oh great , more fires in bound 🤦🏽‍♂️

    • Six_Tymes

      no offence, but you didn’t get it, this no doubt is an attempt to suppress flames.

  • Six_Tymes

    something to hopefully suppress the instant ULTRA HOT flames that incinerate people when EV’s are in accidents.

  • surfshop

    Liquid fluid? as opposed to?

    • Knotmyrealname

      Solid fluid!!
      …or liquid solids…

      • ChicagoBlah

        The same as solid diarrhea

        • Knotmyrealname


  • Craig

    What a colossal waste of time.

  • charlotteharry57

    But of course, the system will be punctured, probably by the sharp nails of a pet doggie. Soon after the system is introed. And here come the huge lawsuits…like the McD one with the spilled hot coffee. Anyone at Tesla have brains? Didn’t think so.

  • Aeromann

    It will burn even faster. 😀

  • Nick

    Liquid Fluid huh, really, a fluid that’s a liquid, amazing.
    Did it take you long to think of that?

  • sidewaysspin

    Perfect minimalism.
