The invention discloses a battery charging circuit, an electric vehicle and a storage medium. The battery charging circuit comprises a heating module temperature acquisition module, a first switch module, a second switch module and a third switch module. The control method of the battery charging circuit comprises the following steps: the battery management module obtains the working temperature value of the heating module; when the temperature of the heating module is lower than a preset low-temperature protection threshold, the first switch module and the second switch module are controlledto be turned off; and the third switch module is turned on to heat the battery through the heating module; when the temperature of the heating module is lower than a preset low-temperature protectionthreshold, the first switch module and the second switch module are turned on. When the temperature of the heating module reaches a target temperature value, the first switch module and the second switch module are turned on, and the third switch module is controlled to turn off to stop heating the battery. When the temperature of the heating module is higher than a preset high temperature protection threshold, the first switch module, the second switch module and the third switch module are controlled to be turned off. The invention is used for solving the technical problem that the existingcharger is continuously heated when the temperature of the battery is abnormal.
