Abstract

A method for reducing a total charge loss of battery cells by equalizing states of charge includes making an initial check as to whether a temperature of at least one balancing unit lies below a preselectable temperature limit. Thereupon a check takes place as to whether a charging process of the battery cells has completed and the state of charge of the battery cells is >90%. A determination then follows as to whether a maximum state of charge difference between battery cells lies above an adjustable limit (DELTA_SoC).
