METHOD FOR OPERATION OF AN ELECTRONIC DEVICE EQUIPPED WITH TWO OR MORE BATTERY PACKS AND RESPECTIVE ELECTRONIC DEVICE

The invention refers to an electronic device () comprising two or more battery packs (), an electric motor () which is operated by electric energy from at least one of the battery packs () at a time, and an electronic control unit () for controlling operation of the electric motor (). It is suggested that the electronic control unit () is adapted for switching operation of the electric motor () cyclically and consecutively from at least one battery pack () to at least one other battery pack (). Switching form one operation cycle to the next operation cycle may be effected depending on the current temperature (T) of the at least one battery pack (), on an electric current () drawn from the at least one battery pack () during the current operation cycle, or on a duration (t) of continuous operation of the at least one battery pack () during the current operation cycle.
