Problems solved by technology

[0005] The traditional manufacturing of lead-acid battery plates for power cannot guarantee the consistency of the active material weight between each plate
If there is no good plate matching technology and the production process is not well controlled, the amount of active materials will be different
Moreover, the lead-acid batteries manufactured by the conventional weighing process have defects such as early capacity attenuation of the plates during use, single lagging phenomenon, and irregular changes in the utilization rate of active materials, which affect the battery life.
Many manufacturers have made improvements in the research on the ratio of the plate, but the plates produced by the current existing technology cannot meet the requirements of the consistency of the amount of active material on each plate and the flatness of the plate.

Embodiment 1

[0044] The power lead-acid battery pack of this embodiment is composed of 4 single batteries of the model 6-DZM-12. When matching the group, firstly weigh the polar plates after the externalization treatment, and make the mass difference less than the set value The polar plates are divided into a group and assembled into a single battery, and then assembled into a single battery such as 6V, 12V or 16V according to the needs, and then charge and discharge each single battery, according to the voltage characteristics during the charging and discharging process. Assembling, further assembling the obtained power lead-acid battery pack, specifically includes the following steps:

[0045] S1: Weigh all positive and negative plates, and make the following judgments:

[0046] Positive plate mass in m 1 Indicates that the mass of the negative plate is expressed in m 2 express,

[0047] If 41g≤m 1 ≤43g, it is judged that the positive plate is qualified, otherwise, it is judged that ...

Embodiment 2

[0067] The power lead-acid battery pack of this embodiment is composed of 4 single batteries of the model 6-DZM-20. When matching the group, firstly weigh the polar plates after the externalization treatment, and make the mass difference less than the set value The plates are divided into a group and assembled into a single battery, and then assembled into a single battery such as 6V, 12V or 16V according to the needs, and then charge and discharge each single battery according to the voltage characteristics during the charging and discharging process. Assembling, further assembling the obtained power lead-acid battery pack, the specific steps included are the same as in Example 1, the difference is that the charging and discharging process in step S3 includes:

[0068] (1) Stand still for the first time, and the standing time is 2 hours;

[0069] (2) For the first charge, the charging time is 3 hours, the charging current is 2.5A, and the charging capacity is 7.5Ah;

[0070]...

Embodiment 3

[0081] The power lead-acid battery pack of this embodiment is composed of 4 single batteries of the model 6-EVF-24. When matching the group, firstly weigh the polar plates after the externalization treatment, and make the mass difference less than the set value The polar plates are divided into a group and assembled into a single battery, and then according to the needs, select 6 single batteries and assemble them into a single battery such as 12V, and then charge and discharge each single battery, according to the voltage during the charging and discharging process The characteristics are matched and grouped, and the power lead-acid battery pack obtained is further assembled. The specific steps included are the same as those in Example 1, except that the charging and discharging process in step S3 includes:

[0082] (1) Stand still for the first time, and the standing time is 2 hours;

[0083] (2) For the first charge, the charging time is 3 hours, the charging current is 3A,...

Abstract

The invention discloses a sorting and grouping method for a power lead-acid storage battery set. The method comprises the following steps: firstly, pole plate sorting is performed according to the weight of pole plates so as to sort pole plates, the quality difference values of which are less than the set value, to assemble single body batteries, the consistency of weight of plate groups in each single body battery is ensured, then single body batteries are assembled to be single batteries according to requirements, charge-discharge is repeatedly performed on the single batteries obtained through assembly, and a plurality of single body batteries are selected for grouping so as to form the power lead-acid storage battery set through the voltage characteristic during the charge-discharge process. According to the sorting and grouping method for the power lead-acid storage battery set, compared with the original grouping ratio, the grouping ratio of the power lead-acid storage battery set is improved 5% through the combination of pole plate sorting and single battery grouping, the problem that the single battery is backward is solved to a certain degree, the probability that single battery is backward is reduced, and the service life of the power lead-acid storage battery pack is prolonged by15-20%.

Description

technical field [0001] The invention relates to the field of power lead-acid battery manufacturing, in particular to a method for sorting and grouping power lead-acid battery groups. Background technique [0002] Lead-acid battery is a widely used chemical power source. This product has the advantages of good reversibility, stable voltage characteristics, long service life, wide application range, abundant raw materials, renewable use, and low cost. In recent years, with the enhancement of environmental awareness and the seriousness of energy problems, lead-acid batteries play an extremely important role as a power source in electric vehicle systems. [0003] Due to the limited driving capability of a single battery, it is usually necessary to combine multiple single batteries together to form a power lead-acid battery pack, where a single battery includes multiple single cells, and each single cell should be understood as consisting of a group of Combination of plates and ...
