Problems solved by technology
[0003] The attenuation speed of power battery life is also affected by the current health, the individual quality difference of power batteries and the use load; however, direct comparison of the attenuation speed cannot well distinguish the weight of these factors on the life of power batteries, so it is necessary to calculate other value to analyze the impact of the power battery usage on the service life separately

The invention discloses a method, a device and equipment for predicting the service life of a power battery and a storage medium. The method comprises the following steps: acquiring operation data of a vehicle; processing the operation data to obtain a plurality of operation parameters; determining a load index of the power battery based on the operation parameters; and determining the residual life of the power battery based on the load index. According to the technical scheme, the load index is obtained based on the multiple operation parameters, and the residual life of the power battery is analyzed based on the load index, so that the problem that the calculation amount is large due to the fact that different operation parameters are analyzed respectively can be avoided, meanwhile, the situation that the influence weights of different operation parameters on the life of the battery are different is avoided, and the service life of the power battery is prolonged. Therefore, the problem that the calculation result is inaccurate is solved, and the accuracy of the result is improved.
Description
technical field [0001] The invention belongs to the technical field of power batteries, and in particular relates to a method, device, equipment and storage medium for predicting the service life of a power battery. Background technique [0002] At present, power batteries are all secondary batteries, that is to say, they can continue to be used by charging; the life of this secondary battery is divided into two types, namely, charge-discharge cycle life and wet shelf life. The so-called charge-discharge cycle life means that after a power battery goes through "how many times" charging and discharging cycles, its battery capacity will drop to a certain value, and this "how many times" is its charge-discharge cycle life. Of course, the longer the charge-discharge cycle life, the better the performance of the battery. [0003] The attenuation speed of power battery life is affected by the current health, the individual quality difference of power batteries and the load at the...
