Abstract

A method for determining charging profiles for device batteries of battery-operated devices. In one instance, the method includes selecting device batteries having the same usage-related load and the same aging state; dividing the selected device batteries into groups; assigning different charging profiles to the groups of device batteries, wherein the charging profiles indicate for a charging operation a maximum permissible charging current depending on a charge level range; operating the device batteries of all groups with the respectively assigned charging profiles for a predetermined period of time, so that charging operations are executed depending on the respectively assigned charging profile; detecting a change in the average aging state for each group of device batteries between the beginning of the predetermined time period and the end of the predetermined time period; and adjusting the charging profile depending on the change in the average aging state.
