The invention discloses an electricity lack prevention control method and device for a new energy automobile, and the method comprises the steps: responding to the received hardwire wake-up information sent by a wake-up source, and entering a working mode from a low-power-consumption mode; identifying whether the vehicle is in an abnormal wake-up condition currently; if yes, continuously monitoring the voltage of the storage battery; and if the voltage of the storage battery is lower than the threshold value, the power-on process is executed under the condition that the whole vehicle has no high-voltage-on-forbidding fault, the direct-current converter is controlled to be started, and the storage battery is charged through the power battery. The voltage of the storage battery is continuously monitored when the vehicle is in the abnormal wake-up working condition, the storage battery is charged when the voltage is lower than the threshold value, and the storage battery is prevented from being lack of electricity and damaged.

    本申请公开了一种新能源汽车的防亏电控制方法及装置,方法包括:响应于接收到唤醒源发出的硬线唤醒信息,从低功耗模式进入工作模式;识别车辆当前是否处于异常唤醒工况;若是,则持续监控蓄电池的电压;若蓄电池的电压低于阈值,则在整车无禁止上高压故障的情况下执行上电流程,控制直流转换器启动,通过动力电池为蓄电池补电。本申请在车辆处于异常唤醒工况时持续监控蓄电池的电压,在电压低于阈值时对蓄电池进行补电,避免蓄电池亏电和损伤。
