I;ve had a bit of a "Eureka Moment" about "Autobidder", it isn't just Autobidder that is powerful, it is Autobidder potentially combined with everything else Tesla is doing.
Specifically this patent:-
Tesla is working on technology to revolutionize the electrical grid with distributed solar power - Electrek
So Autobidder is the brains and the grid control patent is the nervous system...
Via that Autobidder control a lot of controlled loads, big batteries, home batteries, EV charging, home HVAC, home hot water.
Autobidder ensures all loads get electricity at the cheapest possible price.
When peak price arrive Autobidder dispatches stored energy, big batteries, home batteries. V2G EVs.
V2G now makes sense if new battery tech displayed on battery day allows regular charging to 80-100%.
For example if your daily travel requires 50% SOC, you can allow Autobidder to use the other 50% of your battery.
What is in it for the Tesla customer is Telsa would give you a cut of the Autobidder profits, so perhaps you car can make money for you just by simply being plugged in at home or work.
Individually some parts of the ecosystem don't seem to make sense, but when we look at the whole system it does.
Tesla will eventually own a fleet of Robo-taxis with million mile batteries, again an opportunity to make a bit of extra cash when plugged in after the shift.
