Abstract: A carbon emission assessment system for recycling of decommissioned battery includes: an information module configured to obtain operation stages of the recycling of decommissioned battery and an input inventory corresponding to each of the operation stages, an instruction module configured to store a carbon dioxide emission calculation formula and carbon dioxide emission factors of different substances, an accounting module, and an analysis module configured to compare the carbon emission results obtained by the accounting module with a pre-stored standard carbon emission to obtain a comparison result, wherein the accounting module is configured to retrieve the carbon emission calculation formula and the carbon emission factors of different substances in the instruction module, in response to the operation stages and the input inventory in the information module inputted by a user, and to obtain carbon emission results for different operation stages.

Abstract: A method and device for defining a carbon emission accounting boundary for recycling of power batteries are provided. The method includes: setting an overall process flow range for the recycling of a decommissioned power battery; according to the overall process flow range, and in combination with an evaluation need corresponding to the carbon emissions accounting, generating a corresponding boundary; according to the boundary, outputting unit processes and an inventory structure corresponding to the recycling of the retired power battery.
