The present invention provides a battery state of health assessment method, a battery state of health assessment device, a storage medium and an electronic device. The method includes the following steps that: the battery parameters of a target battery are determined, wherein the battery parameters include the capacity increment of the target battery, the discharge capacity of the target battery and the battery internal resistance of the target battery; the battery parameters are analyzed with a first model, so that the state of health of the target battery can be determined, wherein the firstmodel is obtained by means of training through machine learning on the basis of a plurality of sets of data, wherein each set of data in the plurality of sets of data include the battery parameters and the states of health of batteries; and identification information for identifying the state of health of the target battery is outputted. With the battery state of health assessment method, the battery state of health assessment device, the storage medium and the electronic device of the invention adopted, the problem of failure to evaluate the state of health of a battery in real time and comprehensively in the prior art can be solved.
