The invention discloses a low-static-power-consumption power management method and system for a whole commercial vehicle, and relates to the technical field of commercial vehicles. The commercial vehicle low-static-power-consumption power management method comprises the steps that relevant parameters of a vehicle low-voltage power source are obtained; re-classifying the related parameters according to a preset classification rule to obtain a plurality of target classification groups; and performing power-on and power-off operation on the plurality of target classification groups based on a preset vehicle power-on and power-off rule, and controlling the whole commercial vehicle to perform corresponding equipment power supply or power failure in a preset state according to the operation instruction, so that the low static power consumption of the whole commercial vehicle is within a preset range. The invention solves the problems that the static current of the whole new energy commercial vehicle is about 50mA and is far higher than the static current of about 15mA of a passenger vehicle at present, so that the possibility of power shortage of a storage battery is caused when the vehicle is parked for a long time, the vehicle cannot be started finally, the service life of the storage battery is greatly reduced after the power shortage of the storage battery, and the fire probability is increased accordingly.

    本发明公开了商用车整车低静态功耗电源管理方法及系统,涉及商用车技术领域。其中,该商用车整车低静态功耗电源管理方法,包括:获取整车低压电源的相关参数;按照预设分类规则对相关参数进行重新分类,以获得若干目标分类组别;基于预设车辆上下电规则对若干目标分类组别进行上下电操作,并依据操作指令控制商用车整车在预设状态下进行相应的设备供电或断电,以使商用车整车的低静态功耗处于预设范围内。本发明,解决目前新能源商用车整车静态电流在50mA左右,远远高于乘用车15mA左右的静态电流,这就会导致车辆在长期停放时,蓄电池有亏电的可能,最终导致车辆无法启动,而且蓄电池亏电后,其寿命会大打折扣,起火概率也会随之增加的问题。
