METHOD AND SYSTEM FOR RECONSTRUCTING COMPLETE CHARGE/DISCHARGE DATA ON BASIS OF PARTIAL BATTERY CHARGE/DISCHARGE DATA

摘要

A method and system for reconstructing complete charge/discharge data on the basis of partial battery charge/discharge data. The battery especially refers to a lithium battery. Said method comprises the following steps: A, obtaining a partial battery charge/discharge measurement data curve containing data of multiple discrete sample points; B, determining the starting point of the partial charge/discharge measurement data curve relative to a pre-set complete central reference data curve; C, determining an approximate curve using the partial charge/discharge measurement data curve and multiple pre-set graded central reference data curves by means of linear reconstruction or least squares reconstruction, and complete the remaining part of the charge/discharge measurement data curve outside of the partial charge/discharge measurement data curve on the basis of the approximate curve and the starting point of the partial charge/discharge measurement data curve relative to the pre-set complete central reference data curve, thereby reconstructing a complete charge/discharge measurement data curve. The present method reconstructs a complete charge/discharge data curve with high precision using only partial charge/discharge measurement data.
