J1772 doesn\'t allow bidirectional charging anyway so it\'s not an issue - there wouldn\'t be any discharge.
CCS does not currently provide the control for V2X (bidirectional charging) but the fact that VW, Hyundai and others have already announced support in their cars indicates it is on the way. It doesn\'t require any hardware modifications as a bidirectional datalink already exists in CCS.
I suspect that Chademo may have virtually died out by then.
2025 is the date that\'s mentioned in this article for bidirectional charging support in CCS.

Yes, it\'s possible to do it all from the EVSE side, but the problem is that the EVSE does not know what car is connected to it. For example, i might allow a Tesla to discharge (feeding the grid) to 50%, but would not want a Leaf to do that. ChaDeMo can tell the EVSE what is connected to it, CCS or J1772 can\'t.
