Storage battery connecting strip loosening early warning method and device and storage medium

The invention relates to a storage battery connecting strip loosening early warning method and device and a storage medium, the storage battery is formed by a plurality of battery monomers, the method comprises the following steps: obtaining the temperature of the battery monomers measured by a temperature sensor in the charging and discharging process, determining whether the temperature of the battery monomers is abnormal according to the temperature, and if yes, determining whether the battery monomers are abnormal; if yes, obtaining the time when the battery monomer works at the abnormal temperature; acquiring the internal resistance of the single battery acquired by the data acquisition module; obtaining the running time after the storage battery is started; calculating a connecting strip looseness index according to the internal resistance, the temperature, the time of working at the abnormal temperature and the operation time of the storage battery of the single battery with the abnormal temperature; w
