249 Tesla Patents – 104 Related To Battery, 28 To Charging, 13 To Motor And 10 To User Interface


With Tesla Motors making all of its patents open source, as long as used in “good faith,” the logical question on everyone’s minds is how many patents does Tesla hold?

Here’s the answer:

Which patents would interest other automakers? InsideEVs had this discussion and we conclude that Tesla’s battery patents (BIG battery stuffed into BIG electric vehicle) are likely of no value to other automakers. However, Tesla’s charging patents (Supercharger) and coolant patents (battery coolant) likely are.

And lastly, we’d be wrong to assume other automakers aren’t interested in some of Tesla user interface patents, especially those linked to the 17-inch touchscreen.

I think it would be interesting to know exactly what aspect of “supercharging” has been patented. I wouldn’t think you could simply patent a general idea of charging a car at a high power……or could you? I don’t know I’m not a patent attorney.

Once you get into the details of how you should go about delivering 135kW into up to 8 cars at a time, I’m sure there is PLENTY of room for novel ideas.

Is it possible they’re giving up the battery patents because they have some better up their sleeve? Like dual carbon?

No. Currently, carbon – carbon isn’t as energy dense as typical li-ons.

As I always suspected . . . Tesla’s main innovation has been in battery packs, battery cooling/heating, battery management, battery packing, battery module isolation, battery charging, battery cost-reduction, battery pack as part of the car structure. etc.

I don’t think anyone expect some car maker in China is going to give Tesla a run for their money in terms of battery size and range for a while even if they did post all their stuff on the internet.

Of course BMW and others are extremely interested in big batteries to be put in big cars! They know that’s the way already NOW (and actually since a few years) for big, high end cars, at least.
They are already suffering a lot from Tesla’s competition.
And that’s why they should be interested in Tesla’s battery pack technology (unless they already have something better under development). (Actually, Musk specifically said “That is something I would recommend”, referring to other automakers assembling small cells into big pack the Tesla way, together with BMW building their own Giga-factory to cut costs).
And also that’s why (I mean, that they’re interest in big batteries for big cars) they’re interested in Superchargers’ access.
If they were not interested in building big cars (and later on also smaller cars) with big battery packs they would not be interested in the Superchargers thing, simply because (among other reasons) Tesla would not allow them to use them (see minimum charging power requirement).
That’s my take… 🙂

Tesla NEEDS other automakers to have access to their patents for a few obvious reasons:

1. Tesla will need other automakers to switch to large underbody battery packs as quickly as possible that require Supercharging(that Tesla will provide for a free) for interstate travel.

2. Tesla expects to be a primary global supplier of large underbody battery packs for next generation 200+ mile EVs manufactured by other manufacturers.

Musk, who only plans to be with Tesla Motors for the next 3-4 years has a long game, and it’s not in selling cars, but in his other two businesses providing battery packs and Supercharging to ALL auto manufacturers and EV owners on a global scale.

The faster other automakers get up to speed with 200+ mile EVs, the more profitable Tesla’s battery and fueling stations will be.

So this is no good will gesture, but part of a long term business plan.

Musk has said he will remain CEO for at least 4 – 5 years. Through the ramp up of Gen III. Then he will evaluate with the board if he will continue.

Musk is still the chairman of the board of Tesla. He will not be giving up that role. So don’t expect the long term vision of Tesla to change, even if he appoints another CEO. It will just be up to someone to deliver on the execution of Musk’s plans.
