1. A battery pack (8) comprising:

  • a number of battery cells connected to two or more terminals (8a) for establishing an electrical power connection with a power source (7), the two or more terminals also for establishing an electrical rower connection with a battery-driven apparatus (9);

    an electronic system (10) comprisinga) a first electronic system (4) for measuring one or more parameters of the battery cells,b) a second electronic system (2) for controlling the charging, discharging, or both charging and discharging of the battery cells in the battery pack (8), andc) a third electronic system (6) for controlling functional modules of the battery-driven apparatus (9) that cause the battery-driven apparatus (9) to perform corresponding functions related to operation of the battery-driven apparatus (9); and

    a communications interface for communicating via one or more communication paths with;

    a) the power source (7) when the charging, discharging, or both charging and discharging of the battery cells is controlled by the second electronic system (2),b) the battery-driven apparatus (9) when the operation of the battery-driven apparatus (9) is controlled by the third electronic system (9) to perform the corresponding functions of the functional modules related to the operation of the battery-driven apparatus (9), andc) at least one other battery pack (8) of a number of battery packs when an electrical power connection is established between, the battery pack and the number of battery packs including the at least one other battery pack (8) and the power source (7) or the battery-driven apparatus (9), or both the power source (7) and the battery-driven apparatus (9), wherein the battery pack (8) exchanges charging or discharging information, or both, with the number of battery packs including the at least one other battery pack (8) and generates a charging or discharging list, the order of battery packs on the list being prioritized according to a number of criteria selected from the group consisting of discharge status, actual temperature, capacity size, cell technology, age, and internal impedance.
