The invention relates to a battery preheating control method and system, an electric vehicle and a readable medium. The method comprises the steps that when it is detected that the battery preheating device is connected with a vehicle, battery state information of a power battery of the vehicle is obtained; determining a target pulse current according to the battery state information; and controlling the battery preheating device and the power battery to alternately charge and discharge by adopting the target pulse current so as to preheat the power battery. According to the scheme, the problem that the low-temperature preheating time of the battery is too long can be solved.
