The invention discloses a vehicle storage battery charging method and device and a storage medium, and belongs to the technical field of vehicle control. The method comprises the steps of obtaining initial voltage of a storage battery of a vehicle; in response to the situation that the initial voltage is smaller than a first voltage threshold value, the temperature of the storage battery and the SOC of the power battery are obtained, and the SOC of the power battery is used for indicating the percentage of the remaining electric quantity of the power battery in the total electric quantity; heating the storage battery in response to the temperature of the storage battery being less than a first temperature threshold; when the temperature of the storage battery is larger than or equal to a first temperature threshold value and the SOC of the power battery is larger than a first percentage, the current voltage of the storage battery is obtained; and in response to the fact that the current voltage of the storage battery is smaller than a second voltage threshold, the power battery is controlled to charge the storage battery, and the first voltage threshold is larger than the second voltage threshold. Therefore, the intelligence of the charging operation of the storage battery is improved, the power shortage of the storage battery is avoided, the health of the storage battery is ensured, and the normal starting and driving of the vehicle are ensured.
