Method and device for evaluating comprehensive performance of power battery

The invention relates to a power battery comprehensive performance evaluation method and device, and relates to the technical field of new energy automobiles. The method comprises the steps that a power battery to-be-evaluated request generated based on power battery input data is acquired, the power battery input data comprises first-level parameters and user requirement indexes, and the first-level parameters are used for representing simulation environment conditions; in response to the to-be-evaluated request of the power battery, constructing a corresponding simulation model according to the primary parameters; whole vehicle simulation analysis is carried out through the simulation model, secondary parameters are obtained, and the secondary parameters are used for representing the adaptation degree between the battery and the vehicle; and comparing the user requirement indexes with the secondary parameters to obtain suggested optimization parameters of the battery. By adopting the method, the comprehensi
