V2G gets all the buzzword points, but... You don't even need V2G (which requires still-rare bidirectional charging hardware) to benefit from free/negative electricity prices. Simple V1G (AKA grid-interactive smart charging) will do the job, and since there's no extra hardware it's just a software update away for many existing EVs. 1. Charge your EVs for free during excessive generation. 2. There is no step 2. This avoids adding extra (relatively costly) cycles to your EV battery, since you only do charging you were already going to do anyway. This improves economics for the owner, because the price "spread" no longer needs to cover battery wear-and-tear. Even if you have onboard V2G hardware, there will be lots of cases where a "Just Do The Right Thing" algorithm would choose to only delay charging (no back-feeding to the grid), since the predicted price spread is less than the battery cycle cost.
