Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] The present invention adopts a novel battery group screening method, installs a corresponding measurement module on the battery screening system, measures the corresponding data through the measurement module, processes the obtained data, and recalculates according to the K-means algorithm based on the genetic algorithm Classification, at the same time, the results of different calculation rounds of the same batch of batteries are retained and compared, and the best result is selected, that is, the individual with the greatest fitness, and the signal is transmitted to the classification control system, and the classification control system executes Classification operation, and at the same time output the classification results to the human-computer interaction interface.

Abstract

The invention discloses a novel battery grouping screening method. The novel battery grouping screening method comprises the following steps: adding a corresponding measuring module to a battery screening system, measuring corresponding data through the measuring module, processing the obtained data, and recalculating a category according to a K-means algorithm based on a genetic algorithm while results of different operation circles of the same batch of batteries are reserved and compared, and then selecting an optimal result, namely, selecting an individual with the maximum fitness, and transmitting a signal to a classification control system, wherein the classification control system executes classification operation while the classification result is output to a human-computer interaction interface. For the novel battery grouping screening method, the advantages of factor analysis, the genetic algorithm and the K-means algorithm are combined; the battery cells with similar consistency are accurately classified into the same category, so that the problem that the later battery grouping is difficult due to different performances of the battery cells is solved; and the novel battery grouping screening method has the advantages of being higher in accuracy, high in operation speed and high in convergence speed.

Description

technical field [0001] The invention belongs to the technical field of battery processing, and in particular relates to a novel battery group screening method. Background technique [0002] Since entering the 21st century, the battery industry has developed rapidly. With the country's strong support for the battery industry, a large number of battery products will be put on the market in the next 10 years, but problems will follow. Among them, how to deal with the consistency of the single battery is an important issue. Especially for the screening of retired batteries with the same consistency, the power battery of an electric vehicle contains hundreds or even thousands of single cells. The inconsistency is obvious. However, these single batteries are not completely scrapped, and there is residual value. Therefore, how to screen these decommissioned power batteries is particularly critical. [0003] At present, the method of battery classification by enterprises is rela...
