Abstract

Disclosed is a method for reconstructing complete charging-discharging data based on partial charging-discharging data of a battery. The method includes following steps: obtaining a partial charging-discharging measured data curve, including multiple pieces of discrete sampling-point data, of the battery; determining a starting point, relative to a preset global center reference data curve, of the partial charging-discharging measured data curve; and determining an approximation curve by means of linear reconstruction or least square reconstruction, and supplementing a charging-discharging measured data curve of a remaining part other than the partial charging-discharging measured data curve according to the approximation curve and the starting point, relative to the preset global center reference data curve, of the partial charging-discharging measured data curve, to reconstruct a complete charging-discharging measured data curve. In the method, the complete charging-discharging data curve can be reconstructed with high precision by using the partial charging-discharging measured data.
