Embodiment 1

[0031] The 6-DZM-12 type of battery to be mixed is subjected to a large-scale battery mixing process, which is successively carried out through battery charge and discharge and detection, free acid extraction, acid extraction sampling inspection, online charging verification, and battery assembly process to form a battery pack. The battery pack that has undergone the large-scale battery mixing process and the battery pack that has not undergone the large-scale battery mixing process of this model are detected, and the data graphs of discharge time, termination voltage and cycle times are obtained. The battery pack of the 6-DZM-12 model in this embodiment The cycle life data picture before the large-scale mixing is implemented figure 1 As shown, the cycle life data of the 6-DZM-12 battery pack after the large-scale mixing is implemented is as follows figure 2 shown.

[0032] refer to figure 1 and figure 2, by comparison, the 6-DZM-12 type battery before the implementation ...

Abstract

The invention discloses a battery large-mixing technology. The battery large-mixing technology comprises the steps of charging and discharging of batteries, free acid extraction, spot check of acid extraction, online charging verification and battery matching, batteries to be mixed are placed on a charging rack to be charged and discharged, four measurements are conducted in the charging and discharging process, the batteries which do not meet technological requirements are not involved in mixing, the batteries which pass through detection, spot check and verification, are off the shelf at the same time in the same production region and have the same types are mixed to form a battery pack. According to the battery large-mixing technology, the processing steps are simple and reasonable; by means of the four measurements, the differences of single batteries in the battery pack are reduced, the consistency of the battery pack is improved, and the service life of the batteries is prolonged; by means of free acid extraction and spot check of acid extraction, residual check of the batteries capable of being involved in large mixing is made to be qualified, and the safety of the batteries and the battery quality are improved; meanwhile, needed staff numbers are greatly reduced, the economic benefit is improved, and the labor cost is reduced simultaneously.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery large-scale mixing process. Background technique [0002] With the development of the electronics industry, it is required to use the same manufacturer, same batch, and same type of battery. However, due to factors such as the battery manufacturer's technology, production batch, and management, there is a certain degree of discreteness in the performance of the actual product. It is hoped that batteries with similar performances should be combined together so that the average discharge capacity of the combined battery pack can reach the minimum average discharge capacity value of the single battery to ensure the performance and life of the battery pack. However, due to the accuracy of production equipment and material characteristics , manufacturing environment differences, process consistency and other reasons, the performance of the battery cells cannot be completel...
