The embodiment of the invention provides an electric energy data collection method and device. A concentrator calculates a collection task of each collector according to the collection needs and issues the collection tasks to a plurality of collectors to enable the collectors to issue collection messages to an electric energy meter according to the collection tasks to collect electric energy data of the electric energy meter; when a collection time is achieved, the concentrator sends a collection command to each collector to enable each collector to pack the multiple collected electric energy data into a data block and upload the data block, then receives the data block and processes the data; so that the process that the data is collected from the electric energy meter is separated from the process that the data is reported to the concentrator, meanwhile, in the process that the data is collected from the electric energy meter, a plurality of collectors carry out meter reading concurrently without mutual inference; and in the process that the data is reported to the concentrator, the electric energy data is packed into the data block, the data block is upward sent to the concentrator through a frame of message, the whole interaction time is shortened, and the whole collection efficiency is improved.
