Embodiment Construction

[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0045] Based on the technical problems existing in the existing working condition formulation method, the present invention analyzes the output power curve of the energy storage battery as a function of time according to the statistical data of the actual operation of the energy storage battery, continuously divides the segments from the original data, and analyzes the The performance parameters of these fragments such as power, power change rate, running time and energy are factored, because although each parameter represents certain information, there is a certain correlation between some parameters, that is, there is no correlation between parameters. are independent of each other, so that the information provided by these parameters overlaps to some extent. It is necessary to find mutually independent elements among these parameters, and obtain a small nu...
