<p>The device (D) has a radio frequency identification type storage unit (MS) integrated with a battery (BA) and storing information data representing characteristic of the battery, where the characteristic is selected from size, capacity, amperage and traceability information. A reading unit (ML) i.e. near field communication, is arranged to determine the stored information data when the reading unit is located in the immediate vicinity of the storage unit to allow estimation of a load state of the battery based on the characteristic represented by the determined information data.</p> |
