A method of detecting the type of a battery pack in a mobile electronic device is provided, which detects the type of a battery pack connected in a mobile electronic device even if no dedicated terminals are provided to a battery pack. (a) A first battery pack connectable to the body is provided. (b
A method of detecting the type of a battery pack in a mobile electronic device is provided, which detects the type of a battery pack connected in a mobile electronic device even if no dedicated terminals are provided to a battery pack. (a) A first battery pack connectable to the body is provided. (b) A second battery pack connectable to the body and different in characteristic from the first pack is provided. Each of the first and second packs has a battery cell, first and second terminals respectively connected to high- and low-potential side terminals of the cell, a third terminal, and a temperature detection element connected across the first and second terminals. (c) The body is provided with fourth, fifth, and sixth terminals connectable respectively to the first, second, and third terminals of the first or second battery pack. The body has a resistive voltage divider circuit connected among the fourth, fifth, and sixth terminals. (d) The first or second pack is connected to the body in such a way that the fourth, fifth, and sixth terminals of the body are connected to the first, second, and third terminals of the first or second battery pack, respectively. (c) An output voltage of the divider is detected to thereby generate a detection result. (f) Whether the first or second pack is connected to the body is detected based on the detection result.

The arrangement according to claim 1, wherein said at least one equipment is one or several of modems, telephones battery rechargers, facsimile apparatus, computers and/or power supply of them. 6. The arrangement according to claim 1, wherein said subscriber location includes a local power backup. 7. The arrangement according to claim 1, wherein said power supply is substantially continuous. 8. The arrangement according to claim 1, wherein said network is one of a Public Switched Telephone Network (PSTN), Integrated Services Digital Network (ISDN) or Asymmetrical Digital Subscriber Line (ADSL). 9. The arrangement according to claim 1, wherein the arrangement is adapted to connect a mobile station of a wireless communication network to said communications network such that the mobile station supplies said communications network with power. 10. A method for supplying power in a communications network comprising a subscriber side and a provider side, said provider side being connected to nodes of said subscriber side through one or more Line Terminals and at least one equipment at said subscriber side being connected to said provider side through at least one Net Terminal, comprising the steps of supplying said communications network with power at least during a period of time through said at least one Net Terminal by means of said at least one equipment. 11. The method according to claim 10, further comprising supplying power during a power supply failure period. 12. The method according to claim 10, further comprising supplying power substantially continuously. 13. The method according to claim 10, comprising a further step of creating an attraction value for a subscriber of the communications network to connect a device for supplying the communications network.
