The invention provides a method for determining the remaining life of an intelligent electric energy meter. The method comprises the following steps of sampling from the Y intelligent electric energymeters of a production batch to be tested to determine an intelligent electric energy meter sample carrying out a multi-level constant stress acceleration test; acquiring the performance parameter values of the intelligent electric energy meter sample when carrying out the multi-level constant stress acceleration test at a plurality of preset monitoring moments; determining the pseudo life value of each intelligent electric energy meter in all the M*Q intelligent electric energy meters of the intelligent electric energy meter sample at a normal stress level according to the obtained performance parameter value of the intelligent electric energy meter sample, a bivariate constant stress acceleration model and an exponential performance degradation model; determining the reliable life valueof the intelligent electric energy meters of the production batch to be tested under a specified reliability value r according to the pseudo life value of the intelligent electric energy meter sample;and determining the remaining life value of the intelligent electric energy meters of the production batch to be tested after being used for N years. By using method, a condition that a large numberof intelligent electric energy meters which have not expired are terminated early can be avoided.
