Embodiment Construction

[0026] The present invention will be further described below through the performance evaluation of lead-acid batteries with different designs for over-abuse and over-discharge.

[0027] Select A design scheme and B design scheme to prepare samples respectively before evaluation, and sample specification is 2V, 200AH lead-acid storage battery in the present embodiment, and quantity is each 9, has 6 to be used for lead-acid storage battery abuse of the present invention in each scheme Over-discharge performance evaluation and capacity recovery method, the remaining 3 of each solution are used for 100% DOD cycle life test.

[0028] For lead-acid battery abuse over-discharge performance evaluation, samples are prepared using design scheme A and design scheme B respectively, and the evaluation environment is 25°C±2°C. The specific steps are as follows:

[0029] 1.1. According to the conventional configuration, 6 lead-acid batteries of the same specification are selected in series t...

Abstract

The invention discloses a lead-acid battery abuse over-discharge performance evaluation. In the evaluation, through a abuse over-discharge performance test, a abuse over-discharge capacity rate Caod is acquired; and then, through a cyclic over-discharge test, a over-discharge capacity attenuation rate Caoc is acquired so as to pre-evaluate the pros and cons of a related design scheme and an over-discharge capability. The invention also discloses a capacity recovery method after lead-acid battery abuse over-discharge. In the method, through deep discharge, a built-in active substance is activated so as to promote the recovery of a backward battery capacity. As a whole, a quantitative evaluation method which is adopted in the invention is simple and accurate, timeliness is good, the method is good for guidance and designing, and a research and development period and cost can be greatly shortened and reduced. A user can timely optimize and adjust the operation efficiency of a matching battery through using the method of the invention.

Description

technical field [0001] The invention belongs to the technical field of lead-acid storage batteries. Specifically, the invention relates to performance evaluation of a lead-acid storage battery overdischarge due to abuse, and also relates to a method for recovering the capacity of outdated batteries caused by overdischarge due to abuse. Background technique [0002] There is a "bucket effect" in the use of lead-acid battery packs, that is, lagging batteries lower the performance indicators of other batteries. Due to the lack of pre-assessment methods for outdated batteries in this industry, especially for over-discharge evaluation of lead-acid batteries, there is also no method for capacity recovery of outdated batteries. Therefore, it happens from time to time that the battery packs used in the project fail to meet the expected performance indicators. If such technical problems are not solved well, it will easily lead to conflicts between the supply and demand sides. In rea...
