Musk Will Open Up Tesla Supercharger Patents To Spur Development

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.'"

The same connector is electrically compatible with both J1772 and the J1772 combo plug..

      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 200RPM, hence more fuel. When the motor is drawing power, the engine supplements the battery; when the motor draws less power (or none), the engine charges the battery.

      This setup allows for plug-in charging, as well as high density fuel usage. We can use excess capacity at hydroelectric dams, solar plants, and wind farms to generate diesel fuel, both direct from air and by fermented waste, e.g, grease fryer oil, corn stalks, or wood pulp. This provides a zero-emission hydrocarbon fuel source which we can pipeline across the country. Combustible waste can go straight into a Fischer-Tropsch process used for gas-to-liquid or coal-to-liquid in modern applications.

      These conversions have high amounts of loss, but are suitable for reclamation. Hydro plants dump millions of gallons of water without power generation when under-utilized; wind farms and solar plants ground their production. Even at 50% efficiency, conversion into fuel provides a valuable commodity.

    I doubt that you could use a Tesla-like Supercharger to charge a battery other than one made by Tesla.

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).

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.

      As long as my car can handle the voltage, draws an appropriate amount of current and (possibly) provides some identification for payment or statistics, I can take that power and charge 18650's, NiCds, SLAs, caps or just run a big stereo for a block party.
