The embodiment of the invention relates to the technical field of electric vehicles, and discloses a battery power shortage early warning method and device, electronic equipment and a readable storage medium, and the method comprises the steps: when a vehicle is powered off, obtaining an environment parameter of the vehicle, a power-off parameter of the vehicle and a target charge state; wherein the power-off parameters comprise the power-off moment of the vehicle and battery parameters, and the battery parameters comprise the power-off charging state, the battery health state and the battery output voltage; according to the environment parameters, the power-off parameters, the target charge state and a target power-lack duration prediction model, determining a target battery power-lack duration of the vehicle; timing is started when the vehicle is powered off, and if the timing duration reaches the target battery power shortage duration, power shortage early warning information is sent to terminal equipment associated with the vehicle. By applying the technical scheme of the invention, the battery power shortage early warning can be carried out when the vehicle is in the non-use state, and the prediction accuracy can be improved according to the actual use scene of the vehicle and the attenuation condition of the battery.

    本发明实施例涉及电动汽车技术领域,公开了一种电池亏电预警方法、装置、电子设备及可读存储介质,该方法包括:在车辆下电时,获取车辆所处的环境参数、车辆的下电参数和目标荷电状态;其中,下电参数包括车辆的下电时刻和电池参数,电池参数包括下电荷电状态、电池健康状态和电池输出电压;根据环境参数、下电参数、目标荷电状态和目标亏电时长预测模型,确定车辆的目标电池亏电时长;从车辆下电开始计时,若计时时长达到目标电池亏电时长,则向与车辆关联的终端设备发送亏电预警信息。应用本发明的技术方案,能够在车辆处于非使用状态下进行电池亏电预警,再者,根据车辆的实际使用场景和电池的衰减情况,可以提高预测的准确性。
