The invention provides a storage battery electricity shortage prevention method, a controller thereof, an electricity shortage prevention control system and a pure electric engineering vehicle, and solves the technical problem of electricity shortage of a storage battery of a vehicle in the prior art. The invention provides a pure electric engineering vehicle storage battery electricity shortage prevention method. The method comprises the steps that a power supply main switch signal of a pure electric engineering vehicle is obtained; when the power supply main switch signal is a closing signal, a control signal is generated, and the control signal is used for controlling a power battery in the pure electric engineering vehicle to supply power to electronic equipment in the pure electric engineering vehicle. Namely, when the main power switch in the pure electric engineering vehicle is closed, the power battery supplies power to the electronic equipment in the pure electric engineering vehicle, and the electronic equipment does not use the electricity of the storage battery to supply power any more, so that the power consumption of the storage battery is reduced, and the probability of power shortage of the storage battery is reduced.

    本申请提供了蓄电池防亏电方法及其控制器、防亏电控制系统以及纯电动工程车辆,解决了现有技术中车辆的蓄电池出现亏电的技术问题。本申请提供的一种纯电动工程车辆蓄电池防亏电方法,包括:获取纯电动工程车辆的电源总开关信号;当所述电源总开关信号为闭合信号时,生成控制信号,所述控制信号用于控制纯电动工程车辆中的动力电池为所述纯电动工程车辆中的电子设备供电。即,在纯电动工程车辆车中的电源总开关一闭合,即让动力电池为纯电动工程车辆中的电子设备供电,电子设备即不再使用蓄电池的电供电,因此,降低了蓄电池的耗电量,减少了蓄电池亏电的概率。
