At present charge anytime attempts to charge to the limit set on the car. For me this frequently results in a fully charged car long before I need to disconnect, which is of no use to OVO or the grid, and I probably didn’t need a full charge anyway.
Could consideration be given to allow the minimum charge needed to be specified or perhaps option buttons(low, medium, high) for the priority the user has attached to needing a fully charged car. This would leave room for “supporting the grid” instead of just draining my 12volt battery while the car is fully charged and idle.
