The invention relates to a battery preheating control method which comprises the following steps: receiving a reservation time request sent by a vehicle-mounted communication module, awakening the reservation time request, and triggering a preheating control process based on reservation time; vehicle state parameters are collected, and whether preheating can be executed or not is judged according to the vehicle state parameters; the preheating duration is determined based on the vehicle state parameters; starting a fuel oil heating device according to the preheating duration, and heating the battery; and monitoring the communication connection state with the vehicle-mounted communication module, and determining the termination condition of the preheating process based on the current preheating state when detecting that the communication connection is interrupted. According to the method, the preheating process can be subjected to staged control before the vehicle is used, three independent wake-up messages are adopted to correspond to the check, calculation and execution stages respectively, accurate control over the wake-up time of the vehicle control unit is achieved, and system energy consumption is effectively reduced.
本发明涉及一种电池预加热控制方法,该方法包括:接收车载通信模块发送的预约时间请求并被唤醒,基于预约时间触发预加热控制流程;采集车辆状态参数,根据车辆状态参数判断是否可执行预加热;基于车辆状态参数确定预加热时长;根据预加热时长启动燃油加热装置,执行电池加热;监测与车载通信模块的通信连接状态,当检测到通信连接中断时,基于当前预加热状态确定预加热流程的终止条件。本发明在用车前能够对预加热的过程进行分阶段控制,采用三次独立的唤醒报文分别对应检查、计算和执行阶段,实现了对整车控制器唤醒时机的精确控制,有效降低了系统能耗。
