Power supply and a vehicle using the same

An object of the present invention is to allow the setting of the ID information more flexible. The A plurality of battery cells and battery blocks 12 connected in series and / or parallel, a communication interface 16 for data communication with other functional modules 10 or the main controller 2, the communication via the communication interface 16 that a data recordable memory unit 18, a current of the battery block 12, a voltage, or a detectable battery state detecting unit 14 at least one of temperature, and a plurality of functional modules 10 including a plurality of functional modules 10 It is connected to, a power supply device comprising a main controller 2, the controlling these, each functional module 10, when connected to the main controller 2, granted a unique address information from the main controller 2 cage, functional module 10, specific granted from the main controller 2 add The scan information, recorded in the memory unit 18, based on the address information, and data communication. .Field
