The invention relates to an electric energy meter with independent metering part and management part. The electric energy meter comprises a metering control module and a management control module. The metering control module is used for acquiring and calculating electric energy data and sending the acquired and calculated electric energy data to the management control module; and the management control module is used for realizing rate control and calculating charging data according to the rate and the received electric energy data. According to the electric energy meter, the problems that a management function of an intelligent electric energy meter needs to be continuously improved and the management part and the metering part are influenced mutually in the prior art are solved; an existing mode of replacing the electric energy meter is overcome to meet the function change demand of a customer on the electric energy meter; the defects of high updating cost and tedious upgrading process of the electric energy meter are overcome; and the running stability of the electric energy meter and the data reliability and traceability of the metering part are improved.
