Currently optimized battery life tries to charge to 100% soc every day, leaving no headroom for unexpected sunny days with lot of solar energy.
A setting to set active soc headroom in percent would solve this issue.
When the soc reaches 100% minus the active soc headroom this would be the signal to the optimized battery life algorithm that the fully charge of that day has been reached and the minimum soc level will be subtracted with 5% as like optimized battery life works. If the soc doesn’t reach this level 5% is added like normal.
Also the minium soc headroom should be subtracted from the maximum active soc limit.
Thus when active soc headroom is 10% the maximum active soc level will be 70%.
