We are not talking about multiple 0-100% cycles daily. The places where pilot programs have been run always left the car with some amount of charge so it can be driven, and you don't normally charge NMC car batteries to 100%. Vehicle batteries have 8 year 100k mile warranties today, and those manufacturers who have spoken on this topic have said that utilizing your battery as grid storage will not violate the warranty (Ford said this about the Lightning, which can do V2G today.) Please stop spreading misinformation and go do some research before you spout FUD like this.

Posting a question in an internet forum counts as doing research, surely? It’s much more persuasive to allow reasonable-sounding questions to arise and receive polite, well-thought-out answers, as happened here, than to have everyone chanting in unison. The latter looks like a lie even when it’s actually the truth.

  Starting paragraphs of misinformation with a vague question is not a get out of jail free card. That comment was full of misinformed nonsense.

  V1G to the rescue! Existing Tesla cars can do V1G (grid-adaptive charging), but not V2G. https://news.ycombinator.com/item?id=34518188 https://news.ycombinator.com/item?id=34518188

How far down do they discharge the battery, then? Like, how much range would you expect to have at the deepest part of the discharge cycle?

  This is something pilot programs are helping to figure out. The ideal case is the driver can set minimum discharge as they can set a maximum charge (that's how it works on the Ford Lightning.) on top of that many EVs have the ability to set a departure time and the vehicle will ensure it is charged to your maximum level at the departure time.
