The invention discloses a batch electric energy meter multi-fault mode recent life prediction method. The fault electric energy meters are operated on site, fault types are different, the fault electric energy meters are classified according to fault modes, and fault mode classification tables are established; the stage failure rate and the cumulative failure rate of each fault mode of the electric energy meter are calculated; Weibull fitting on the single fault mode is carried out; a part of fault mode prediction results is optimized according to the goodness of fit; the stage failure rates of all fault modes are accumulated; an overall life prediction value of the batch electric energy meter is obtained. The method can provide reference for electric energy meter alternation in advance and risk early warning, and provides technical support for electric energy meter state replacement. 本发明公开了一种批次电能表多故障模式近期寿命预测方法。现场运行故障电能表，故障类型各有差异，本发明按照故障模式对故障电能表进行分类，建立各故障模式分类表；计算电能表各故障模式的阶段失效率和累积失效率；对单故障模式进行威布尔拟合；根据拟合优度情况，优化部
