Abstract

A server for allocating a rechargeable battery among a plurality of roles performed by a group of devices removably connectable with the rechargeable battery, receives for each role from a subgroup of devices, data sets corresponding to respective operational periods. Each data set includes an identifier of the rechargeable battery; a measured capacity; and a measured energy consumption during the operational period. The server: determines and stores, based on the measured capacities, a predicted capacity of the rechargeable battery; determines and stores, for each role, a predicted energy consumption per role based on the measured energy consumptions; obtains an allocation defined by the identifier of the rechargeable battery and an identifier of one of the roles; compares the predicted capacity with the predicted energy consumption corresponding to the obtained role; and when the predicted energy consumption corresponding to the one of the roles exceeds the predicted capacity, generates an alert.
