The invention discloses a battery state detection method, circuit and device, electronic equipment and a storage medium, and belongs to the technical field of battery detection. The method comprises the steps that a first voltage signal of a target detected battery pack in a plurality of battery packs to be detected is collected, a second voltage signal of a sampling resistor connected between an anode of the target detected battery pack and a constant current source in series is collected, and the constant current source is used for outputting an alternating current signal to the battery packs to be detected; calculating the internal resistance of the target tested battery pack according to the first voltage signal, the second voltage signal and the alternating current signal; detecting the current environment temperature of the battery pack to be detected, and obtaining the reference resistance of a reference battery at the current environment temperature; and according to the internal resistance and the re
