Add 'remaining KWh' field/summary at the top for completed charge based on charge limit.

Hi,

Would it be possible to add a 'remaining kwh' field at the top which calculated the amount of kwh required until the charge limit has been reached? It shows remaining time so kwh should be possible too I suppose. This would be quite handy to have to see if I can 'charge it fully' with the kwh I have made that day with solar panels.
