The invention discloses a battery preheating method and a battery preheating system, and belongs to the technical field of vehicles. The battery preheating method comprises the steps that the server awakens the remote information processor at the awakening moment, and the awakening moment is determined based on the vehicle using time set by a user and the preset heating duration. The telematics processor wakes up the controller and the battery management system. The battery management system obtains the current temperature of the battery and sends the current temperature of the battery to the controller. The controller determines the target heating duration based on the current temperature of the battery and the battery heating MAP, and the battery heating MAP is a function relation graph among the heating duration, the current temperature of the battery and the heating cut-off temperature of the battery. And the controller controls the battery management system to preheat the battery based on the target heating duration and the vehicle using time of the user. By adopting the technical scheme of the invention, the cruising ability of the battery can be improved.
