Summary:The invention discloses a lithium ion battery fractional order modeling method based on an improved immune algorithm, and belongs to the technical field of lithium ion batteries. The method comprises the following steps: firstly, respectively establishing fractional order models of the lithium ion battery in a working state and a static state; then determining an OCV-SOC polynomial of the lithium ion battery; then, constructing an improved immune algorithm aiming at lithium ion battery model parameter identification; and finally, identifying each parameter in the fractional order model by using an improved immune algorithm and establishing a complete model. According to the method, the problem that a traditional battery model is not suitable for a lithium ion battery in a standing state is solved, the established fractional order model is more accurate, the identification expression of the fractional order model is established, identification is carried out by using the improved immune algorithm, model parame
