Terminology: v2g - vehicle to grid v2h - vehicle to home v2l - vehicle to load (any kind, presumably, say at a construction or camping site) ====================from the article========= EV CHARGING Home is where the EV is Roschetzkyistockphoto/Getty Images It could prove difficult to convince EV owners to sell energy back to electric utilities for a few cents at a time, but using a car battery as backup power for a home seems like a no-brainer. While  pilot programs for vehicle-to-grid (V2G) technology  are beginning to pop up in several states, vehicle-to-home (V2H) applications seem poised to gain traction more quickly.

https://pv-magazine-usa.com/ Keeping up with the news on PV; lot of talk about storage and tying solar to grid to storage. A couple of recent articles: Alsym’s batteries, made from readily available materials without lithium or cobalt, will be produced for electric vehicles, stationary storage, and marine applications. Alsym Energy emerges from stealth mode to introduce non-flammable batteries – pv magazine USA and: Electric vehicle battery capable of 98% charge in less than ten minutes Enovix also demonstrated its US-made silicon anode lithium-ion batteries can charge 0% to 80% in five minutes. Electric vehicle battery capable of 98% charge in less than ten minutes – pv magazine USA Thanks DJ.

Maybe the controller circuits to manage these batteries will become more generally available and scaled for home use.  We can only hope.    https://www.wsj.com/articles/ old-electric-vehicle- batteries-are-getting-a- second-life-11655114401 Millions of electric vehicles will be scrapped in the coming years. For the batteries that power them, that won’t be the end of the road. Eventually, auto makers and recycling companies want to harvest valuable materials from old EV batteries to make new ones. But before they are recycled, used batteries could be given a second life on the electricity grid. Old Electric-Vehicle Batteries Are Getting a Second Life Auto makers like Nissan and Renault are using retired batteries to build large-scale energy-storage systems  A grid-storage unit in West Sussex, U.K., part of a project from Renault SA and Connected Energy using second-life EV batteries from Renault vehicles.
