Step S2, traversing and counting out the problem battery cells 1 in a preset working link, and replacing the problem battery cells 1 by adopting a reasonable charging and discharging rule to form a latest link; specifically, the link is formed by connecting a plurality of battery cells 1. The selection of the link is determined according to the actual load size; this step includes the following multiple sub-steps.
Step S21, counting the problem battery cells 1 in a preset working link, performing secondary determination after counting, and arranging according to the sequence of the links to be used as a data set to be processed; specifically, in the secondary confirmation process, preliminary screening and elimination are performed, and a data set to be processed is formed.
Step S22, a screening model is established according to reasonable charging and discharging rules, and the screening model is based on electric quantity information and position information and is matched with an optimal replacement criterion as an auxiliary; inputting a data set to be processed, and outputting an optimal non-working link battery monomer 1; specifically, firstly, a screening model is trained, a historical data set to be processed and a historical non-working link battery monomer 1 are used as training samples, training is performed, and a corresponding mapping relation is established.
Step S23, establishing a latest link, wherein the latest link is used as a basic working link of the next cycle; in particular, the process may be cycled.
In this embodiment, firstly, after counting the problem battery cells, performing secondary determination, performing primary screening and removing, forming a data set to be processed, taking the data set to be processed as input, taking the best non-working link circuit cell as output, and building a screening model according to reasonable charging and discharging rules, wherein the screening model has a deep learning function, and the accuracy and timeliness of data are ensured.
The reasonable rule of charging and discharging in the invention comprises the following specific processes: firstly, a plurality of non-working link battery cells 1 closest to the real-time electric quantity information related data of the problem battery cells 1 are found out through inspection; then, the specific position of the battery cell 1 in question is determined, the same battery module 2 and the same row and column are used as the optimal replacement criteria, and the optimal non-working link battery cell 1 is determined by considering the lowest cost principle. In this embodiment, the number of non-working links closest to the real-time power information related data is preferably 10, and may be changed according to the actual computing capability or situation. Judging whether the battery module is the same as the battery monomer in question in the selected non-working link, if so, selecting and replacing the battery module preferentially; if not, judging whether the battery monomer is in the same row and column with the battery monomer in question, if so, selecting the battery monomer in question preferentially, and if the battery monomer is in the same row or column, selecting the battery monomer in question for replacement according to the lowest cost; if the two rows are not in the same row, the selection and replacement are directly carried out according to the principle of lowest cost.
