Option to set Maximum charge level

There should be an option in the setting menu to set the maximum charging level. it is not a good habit to charge any lithium battery to 100% every day. it will reduce its life expectancy. right now if we charge at our home over night, there is no option of limiting the maximum charge level like 80% or 90%.

also there should be an option for very slow charging to charge our ev overnight. for example if we plug the charger at 9 P.M. it gets fully charged (or the max charge level we set in the settings) in the next morning 8 A.M.

this smart charging principle is implemented in many modern smartphones to extend battery health.
