【 摘 要 】

The mathematical model is established by using the sampling data of the discharge curve of different batteries and the recording data of different attenuation state discharge of the same cell. Analysis of the same batch of new battery at different discharge current intensity test complete discharge curve of sampling data, based on quadratic function model, through matlab simulation, get the current strength of the corresponding function. In order to find the residual discharge time of the battery and the higher accuracy of MRE, select the relation between the time and voltage of the exponential function. Finally, in the model improvement, the turning point of the discharge curve is the segmentation point, and the discharge curve is fitted with the.
