The MHIHHO algorithm optimizes the charging pile''s discharge power and discharge time, as well as the energy storage''s charging and discharging rates and times, to maximize the charging pile''s revenue and minimize the user''s charging costs.
And for stationary energy storage, it means the battery can store less energy and thus generate less revenue. How fast the capacity decreases depends on a number of factors including the type of battery, the charging and discharge rates, the temperatures it is exposed to, and the number of cycles it has undergone.
