Problems solved by technology

However, the prediction of the number of remaining battery cycles is a relatively complicated process. The existing battery life prediction usually has a long test cycle and low efficiency, which is not suitable for engineering applications. Moreover, it is impossible to make a comprehensive prediction. Therefore, how to quickly and comprehensively predict Battery Life Becomes a More Concern

Abstract

The invention provides a battery life prediction method, device and equipment, and the method comprises the steps: obtaining a to-be-processed battery, determining an evaluation condition corresponding to the to-be-processed battery, carrying out the charge-discharge cycle test of the to-be-processed battery according to the evaluation condition, and obtaining the attenuation rate of the battery, thereby achieving the prediction of the life of the battery. And determining the service life of the to-be-processed battery based on the relation curve of the cycle index and the attenuation rate, thereby solving the problems of relatively long test period and relatively low efficiency of the existing battery service life prediction, and being suitable for engineering application. Moreover, according to the embodiment of the invention, the battery life under different attenuation rates can be predicted based on the relation curve of the cycle index and the attenuation rate, so that the battery life prediction is more comprehensive. In addition, according to the embodiment of the invention, the service life of the battery under different evaluation conditions can be predicted, and various application requirements are met.

Description

technical field [0001] The present application relates to the field of battery technology, and in particular, to a battery life prediction method, device, and device. Background technique [0002] With the gradual industrialization of electric vehicles, a large number of automotive batteries will be eliminated in the next few years. Although power cells cannot continue to be used in electric vehicles, they can also be used in other occasions with lower requirements for cells, such as energy storage systems. [0003] In the related art, when the capacity of the vehicle power battery attenuates to below a certain percentage of the initial capacity, for example, below 80%, the cruising range on a single charge is significantly reduced, which means the end of the on-board mission of the vehicle power battery. However, for energy storage applications with low specific energy requirements, power batteries still have great use value. Through cascade utilization, not only the perfo...
