Musk Will Open Up Tesla Supercharger Patents To Spur Development 230

Posted by samzenpus from the here-you-go dept.
redletterdave (2493036) writes "Elon Musk has said repeatedly he wants to 'do something controversial' with Tesla's collection of electric car patents, but he finally offered specifics at the UK launch of his Tesla Model S on Sunday. The Tesla Motors CEO said he would like to open up the designs for his Supercharger systems — the free fast-charging stations designed to quickly refuel Tesla's electric cars — to create a standard for other car makers to use. Musk previously said he didn't want Superchargers to become a 'walled garden.'"

    1. Build an electric car that's heads and shoulders above the competition.
    2. Build an innovative charging infrastructure to allow for long distance driving.
    3. Open up the technology for that charging infrastructure so that gas stations and the like can start getting in on the action and making some profit.
    4. With charging infrastructure becoming ubiquitous, that takes away many people's concerns about buying your car.
    5. Also, with charging infrastructure becoming ubiquitous, that may encourage other auto manufacturers to move past compliance cars and actually start selling quality vehicles.
    6. Tout competition's success as your own success, as it's built on your platform. Competition isn't only good PR in this context, but it carries with it the subtext that electric cars are a product category that is here to stay.

    To some degree, I still like the idea of plug-in hybrids for the time being. But if this "open supercharger" thing is as successful as I think it's going to be, there could be a sea change in the consumer automotive market.

    • Plug-in diesel hybrids would probably be better, especially with an all-electric drive train.

      An all-electric drive train allows a light diesel engine to run in its most efficient operating range continuously, under variable load. The engine could be a single-piston diesel pegged to 200RPM, getting more fuel when the battery charge is below 85% and when there is current draw by the motor.. The increased load (by charging or supplying power) would require more torque output for the engine to maintain 200

    but...

    I doubt that you could use a Tesla-like Supercharger to charge a battery other than one made by Tesla. I'm not talking about DRM, I'm talking about the architecture of the battery pack itself - its charging characteristics, its safety features, its cooling system, and so on down to the level of the individual 18650 cells. Those aspects are still heavily protected - licensing and manufacturing the packs and powertrain is a side business for Tesla. So what looks like a move to open up the world could, like other standards, become a way to lock in a particular proprietary design.

    I still think it's pretty cool, though. If it sheds more light on how Tesla has designed and constructed their pack, which is a fine technology, as well as directly showing ways to charge Li-Ion packs quickly, then I think this is a benefit to anyone interested in how electricity is used and stored (i.e., everyone). But I also like to keep in mind that Musk, for all his altruism, is still a capitalist and wants his vision of the future to be the one to succeed.

        Actually, battery chargers are kinda like networking standards. Yes, you have voltage and heavy gauge wire, but you also have two-way communication between the pack and the charger. Most of that is contained within the car itself, but it extends to external charge sources, too. Have a look at the SAE charging standard for EVs [wikipedia.org]. Tesla does not adhere to this standard, either for its connector or communications, which I will guess

      Disclaimer: I know nothing about the Tesla Supercharger.

      But I do know generally how chargers work - specifically multi-cell lithium chargers. Each cell requires a charge management circuit. I don't think the Supercharger actively manages the cell level charging. It is highly unlikely that given 10s or 100s of cells in a Tesla pack that there is going to be anything other than voltage, current and maybe a serial data line for that can be used for metering and financial charging.

    • All you have to do on the charging side is supply power in a certain standard way (AC vs. DC, high voltage vs. high current) and let the car decide how much current to pull. A standard interface between charger and battery controller is also important, otherwise there's a need to drop down to lowest common denominator charging (kinda like incompatible USB charging standards).

      Tesla's superchargers use the same signalling standard as the J1772 combo plug. The car tells the charger what voltage and current to put into the battery so the charger is not tied to any one type of battery.

  • It's a nice gesture but AFAIK none of the other currently available designs can handle the amount of current that supercharger provides. Perhaps in 3-5 years when the other auto companies revamp their existing lineup with new designs they might decide to design around the supercharger 'standard' but I'm not holding my breath.

    Electric cars are not ubiquitous because range and ability to charge is a concern. Charging stations are not ubiquitous because electric cars are not ubiquitous.

    Gasoline automobiles were able to take off when they were invented because the liquid fuel infrastructure was in largely in place prior to their invention. Kerosene for lamps was distributed by metered pumps that were easily converted to dispense gasoline.

    Establishing a standard charging station would allow companies to make the investment in charging infrastructure, confident that it would be widely applicable to different vehicles and would not disappear overnight. When you can pull into the CircleK and purchase a few kWh of juice while grabbing a burrito, that's when electric cars will really take off.

    Tesla isn't just a car company, they are a technology firm. The *real* value of Tesla (hence the stock price) is in the technology they own and control.

    If Teslas chargers become "the standard", then the rest of the world will likely have to license Tesla's other technology to be compatible. This is akin to; anyone can build an ARM-based chip, but you have to license that right from the ARM group, which makes their stock (currently) more valuable then Intels.

    Tesla running gear may also become the defacto standard for electric cars, and once the price drops, near unbiquitous -- which will make Musk extremely wealthy. Tesla won't have to make cars anymore, simply license the tech to everyone else to build.

    They then can pour that money into more R&D and build even better and better running gear which in turn, all other manufacturers will need to license to keep up with the competition.... Which of course, will keep them very wealthy.

    • It's not that I don't agree with your general point, but the ARM vs. Intel example is absurd.

      The price of an individual share is meaningless (unless it's 0). ARM's stock price might be more than 30 times higher than Intel's, but Intel is still worth more than 10 times more than ARM.
