The invention discloses a power battery heating control method, a vehicle and a computer readable storage medium, and the power battery heating control method is used for a vehicle control unit and comprises the steps that when the vehicle is in a dormant state, an effective wake-up signal and a timed heating request which are regularly sent by an Internet of Vehicles system are received; determining that the timing heating switch is in an on state, and responding to the timing heating request; determining that the vehicle meets the constraint condition of entering the timed heating working condition, and controlling the vehicle to enter the timed heating working condition; a battery management system (BMS) wake-up signal and a parking heating instruction are sent to the battery management system, and the parking heating instruction is sent to the battery management system; in response to a battery self-heating request sent by the battery management system, controlling high-voltage power-on of the whole vehicle; and determining that the high-voltage power-on of the whole vehicle is successful, and sending a heating relay closing control request to a battery management system to control the power battery to start self-heating. After the whole vehicle is dormant, it can be reasonably and effectively guaranteed that the power battery is automatically heated in the low-temperature environment, and reliability is high.
本发明公开了一种动力电池加热控制方法、车辆和计算机可读存储介质,其中,动力电池加热控制方法,用于整车控制器,包括:车辆处于休眠状态下,接收到车联网系统定时发送的有效唤醒信号和定时加热请求;确定定时加热开关处于开启状态,响应定时加热请求;确定车辆满足进入定时加热工况约束条件,控制车辆进入定时加热工况;发送BMS(Battery Management System,电池管理系统)唤醒信号和驻车加热指令至电池管理系统;响应于电池管理系统发送的电池自加热请求,控制整车高压上电;确定整车高压上电成功,发送控制加热继电器闭合请求至电池管理系统,以控制动力电池开始自加热。能够在整车休眠后,合理有效地保障动力电池在低温环境下实现自动加热,可靠性高。
