"Tesla will not initiate patent lawsuits against anyone who, in good faith, wants to use our technology." The words "public domain" are never used, although there is some handwaving about "open source".
. . . . . snip . . . .
In any case, it's at best tangential to the subject at hand ... snip....
agreed it's tangential - & that's good ... if we move past the picky-uni dialogue of open-source/licensing distinctions - I won't have to remind who brought it up in the 1st place -
Let's say a Tesla outdoor SC costs (for equipment, permits, insurance, install-construction, property lease/purchase, materials, etc.) > $40k - which may be high or low ... remembering, we're not going to get picky uni. Now you have to give value to monthly / yearly maintenance costs, especially after any warranty expires .... and, equally important here in So Cal (&other areas too), one has to factor in what utility companies refer to as "demand fees".
In short, commercial rates for a large draw on electricity can easily run in 4 to 5 figures if during ANY billing cycle, your instantaneous usage exceeds a given amount. That's no big deal, if you're a hospital or a Nordstroms or a theme park, because your already paying the demand fee. But if you run a Starbucks? ... or some other mom n pop business? You won't be able to afford to loose money for the 3 to 5 dozen possible users per week.
Now what some private CHAdeMO commercial owners do, is program down the unit's draw, to say ...
50kW's max. Limiting a DC quick charger output can save a lot on demand fees .... especially for a business that isn't in the quick charge business anyway. But it still may give rise to bringing in the EV owner's patronage.
Either way you slice it, you are looking at a large cost .... startup, maintenance, & power usage. That brings me full circle back to the aftermarket supercharger. Innovative people look at a product, and try to figure a cheaper way to build the mousetrap - so that they can make money on the same item. If Elon Musk isn't going to chase after manufacturers for building cheaper superchargers, then it seems like all sides win ... more businesses may consider adding a supercharger to draw in customers, Tesla's format gets expanded, and the cheap manufacturers profit as well.
