The invention discloses a battery performance acquisition method and device, equipment, a storage medium and a vehicle. The method comprises the following steps: acquiring a first actually measured external characteristic parameter value of a first battery in a first aging state; inputting the first actually measured external characteristic parameter value into a trained first electrochemical model to obtain a first internal physical parameter value of the first battery in the first aging state, the trained first electrochemical model is obtained by training on the basis of historical actually-measured external characteristic parameter values of at least one battery in different historical aging states; and determining a performance parameter value of the first battery in the first aging state by using the first internal physical parameter value. According to the invention, the acquisition accuracy of the battery aging performance can be improved.
