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.

    本申请公开了一种电池预加热方法及电池预加热系统,属于车辆技术领域。电池预加热方法包括:服务器在唤醒时刻唤醒远程信息处理器,其中,唤醒时刻基于用户设置的用车时间以及预设加热时长确定。远程信息处理器唤醒控制器和电池管理系统。电池管理系统获取电池的当前温度,并将电池的当前温度发送至控制器。控制器基于电池的当前温度以及电池加热MAP,确定目标加热时长,其中,电池加热MAP为加热时长、电池的当前温度与电池的加热截止温度之间的函数关系图。控制器基于目标加热时长以及用户的用车时间,控制电池管理系统对电池进行预加热。采用本申请的技术方案,能够提高电池的续航能力。
