Not sure that's worth it. Cooling batteries is tricky, and cars are designed for high loads with high airflow. Draining a car when it's in a hot garage isn't going to be battery friendly. Adding extra cooling, DC -> AC inverter, and related infrastructure is going to cost weight, space, and money. Not sure it's worth the wear and tear for peak clipping, especially since charging off peak is a form of peak clipping. Instead of having the grid pay to wear down EV batteries, seems like there's better places to put that money that will have more benefits. Obvious choices being solar, wind, grid scale batteries, incentives for covering parking lots with solar panels, etc.
