Identification method for improving single-battery capacity consistency in storage battery pack

Abstract

The invention aims to provide an identification method for improving single-battery capacity consistency in a storage battery pack. The identification method includes the following steps: (a) codes representing the battery gears and the battery capacities are assigned for single batteries, wherein the codes can be numbers, letters or a combination of numbers and letters and are used as distinguishing logos in a production process; (b) after determination of the gears and the capacities of the single batteries is finished, the codes corresponding to the battery gears and the battery capacities are respectively scrawled on shells of the single batteries, the single batteries having the same codes are subjected to unified circulation, and the codes are used for distinguishing in subsequent operation and storage; and (c) in a preorder of making the single batteries marked with the same codes into a storage battery, the codes are cleared firstly, then cover pressing is carried out, and the single batteries are assembled into the storage battery. The method is simple, allows the gears and the capacities of the single batteries in the production process to be identified through the codes, is beneficial for workshop operating personnel to identify and operate, is easy to operate, and ensures the gears and the capacities of a plurality of single batteries in the produced storage battery pack are consistent.

Description

technical field [0001] The invention relates to the technical field of storage battery manufacturing, in particular to a production identification method for improving the capacity consistency of a single battery in a battery pack. Background technique [0002] In order to provide sufficient driving force for electric mopeds, it is necessary to combine multiple single batteries to form a power lead-acid battery pack with high driving capacity. If the capacity of multiple single batteries that make up the power lead-acid battery pack is inconsistent, the performance of a single battery will lag behind (generally lagging in gear and capacity), and the greater the difference in capacity of a single battery, the lagging of a single battery will occur. The higher the probability. If there is a slight difference between a single battery and other batteries in a group of batteries, after several cycles, the difference will become larger, and finally the capacity of the whole group...

However, the existing marking method is to paste stickers. Since the stickers are easy to soak and fall off in an acidic environment, the model of a single battery is unclear, and it needs to be re-tested and judged, which wastes manpower, and even causes the wrong model to be used, affecting the battery. Therefore, how to improve the consistency of the capacity of a single battery in the battery pack is particularly important
