Identification method and device of battery management system sub-module

The invention discloses an identification method and device of a battery management system sub-module. In the method, a plurality of dial switches are used as the input ends of address pins of the battery management system sub-module; and the state sequences of different dial switches are set for different battery management system sub-module, so that machine identification and artificial identification of the battery management system sub-module are realized. The method and the device have the advantages of simplicity, practicality, intuition, universality and the like.
