Embodiment 1

[0031] This embodiment is a long-life valve-regulated lead-acid battery with a nominal capacity of 300Ah. There are three manifestations of the end of life of this type of battery product. The first is that the positive plate grid has been corroded, and the second is that the interior has lost water and dried up. The third is active substance failure. As long as any of the above-mentioned failure modes occurs in the long-life valve-regulated lead-acid battery in use, it can be determined that the product life is terminated. Under normal working conditions, the failure of the product is mainly determined by the application conditions. The short life is only one year, and the long life is 6-8 years. In order to accurately obtain product life data as soon as possible, the present invention proposes a quick detection method for the life of long-life valve-regulated lead-acid batteries. The method first randomly samples the same batch of products. In this embodiment, a total of 6 s...

Abstract

The invention discloses a long-life valve regulation type sealed lead acid battery life quick detection method. The long-life valve regulation type sealed lead acid battery life quick detection method includes the steps: performing random sampling in the same batch of products, equally dividing the samples into two groups, in the same detection environment, applying a circulating charging and discharging detection method to one group, applying a constant current charging detection method to the other group, converting the two groups of detection data into the life of products, and taking the minimum life value as the life of the product. The long-life valve regulation type sealed lead acid battery life quick detection method can accelerate verification of the life of the product by increasing the discharging and charging currents and increasing the discharging depth of a battery. The long-life valve regulation type sealed lead acid battery life quick detection method can greatly reduce the life detection time, thus saving the detection cost of the manufacture party, enabling the demand party to know about the product life as soon as possible, and being convenient for arranging an ordering contract practically.

Description

technical field [0001] The invention relates to a method for detecting the life of a lead-acid battery, in particular to a method for quickly detecting the life of a long-life valve-controlled sealed lead-acid battery. Background technique [0002] Valve-regulated sealed lead-acid battery is a kind of traditional energy storage product, and the market has a large amount. Valve-regulated sealed lead-acid batteries can be divided into three types according to the application occasions: starting type, floating charge standby type and recycling type. The starting type products are specially used for starting vehicles or equipment, and their working conditions require high-current discharge performance, and the lifespan stipulated in the quality standards of this type of products is only one year. Float-charge backup products are emergency batteries, which are usually in a charging state and can be discharged when needed. The working condition requires the battery to have good o...
