The invention discloses an intelligent electricity supplementing method and system for an electric vehicle and a storage medium. The electricity supplementing method comprises the steps that the power supply voltage V1 of a power supply port Pin1 of a vehicle control unit VCU is detected; if V1 is greater than a preset charging voltage upper limit Vm, the VCU application layer sends next wake-up time T1 to the bottom layer; if an external wakeup source wakes up the VCU in the T1, the bottom layer firstly clears the originally given T1 and then gives an infinite wakeup waiting time; otherwise, the RTC timing clock will actively wake up the VCU after the time T1; detecting the power supply voltage V1 of the Pin1; if V1 is greater than Vm, the VCU application layer sends the next T1 to the bottom layer; otherwise, the VCU initiates a high-voltage request according to the collected low-voltage signal and sends the charging time according to the detected small battery voltage, the small battery voltage signal loss does not exist, meanwhile, signal interaction among components such as an EBS, a GWM and a Tbox is reduced, and the load rate of a CAN bus is reduced.

    本申请公开一种电动汽车智能补电方法、系统和存储介质,所述补电方法包括检测整车控制器VCU的供电口Pin1的供电电压V1的大小;若V1大于预设的补电电压上限Vm,则VCU应用层向底层发送下次唤醒时间T1;若T1内有外部唤醒源唤醒VCU,则底层会先清除原先给定的T1,再给定一个无穷大的等待唤醒时间;否则T1时间后RTC定时时钟会主动唤醒VCU;检测Pin1的供电电压V1的大小;若V1大于Vm,则VCU应用层向底层发送下次T1;否则VCU内部根据采集到的低电压信号发起上高压请求,并根据检测到的小电池电压发送补电时间,本申请不存在小电池电压信号丢失,同时减少了EBS,GWM,Tbox等部件之间的信号交互,降低了CAN总线的负载率。
