Abstract

The present disclosure relates to a system with a household appliance, a charging station and a plurality of battery units. A control of the system is configured so that a battery unit connected to the charging station can be charged in dependence on a discharge of a battery unit which is connected to the household appliance for operating the household appliance to perform a use operation. The present disclosure further concerns a household appliance and a charging station. It is thereby made possible to perform particularly long use operations with only two battery units or at least a reduced number of battery units without an interruption for charging a battery, and at the same time to achieve the longest possible service life of the battery units.
