It’s coming. With my solar, and more importantly battery, installation, I have signed up to be part of a VPP (virtual power plant). This means that some times the batteries will charge of the grid and sometimes discharge to the grid. This is controlled by “something” (don’t exactly know how it works) central that will make the VPP balance the grid - if there’s too much energy it will charge the batteries and not enough it will discharge. A few companies already got this going and you will be paired more than what you could sell to the grid (apparently). It’s not super often (apparently) that the VPP goes into action.
I’m in Denmark but would guess other countries are doing similar. It’s called Netbalance (Net Balance) and not sure what other countries call it.
Well that’s a software update. Software defined means more changes - like a software defined radio, it will change from being a Bluetooth device to a WiFi device. Can’t see how that will benefit a car. “Small” features, yes. My car suddenly a dump truck, no thanks.
