Abstract

The invention provides a method for measuring the grid current distribution of a lead-acid storage battery, and belongs to the technical field of storage batteries. The method comprises the steps of connecting the plate lug of a to-be-measured grid with a battery charging and discharging system; connecting a wire to the intersection of the transverse rib strip and the longitudinal rib strip of theto-be-measured grid; connecting a storage battery between the other end of the wire and the battery charging and discharging system; measuring and discharging the storage battery by means of the battery charging and discharging system; measuring and recording the current value on each wire. According to the invention, by means of the method for measuring the grid current distribution of the lead-acid storage battery, the grid current distribution of a to-be-measured grid can be accurately measured. Therefore, according to the current distribution condition, the structure of the grid and the size of rib strips can be designed, so that the purpose of reasonably designing the grid is achieved. As a result, the starting capacity and the corrosion resistance of the battery are improved, and the service life of the battery is prolonged. The cost can be reasonably controlled, and the performance of the battery is further improved. The service life of the storage battery is prolonged.

Description

technical field [0001] The invention belongs to the technical field of accumulators, and more specifically relates to a grid current distribution measurement method for lead-acid accumulators. Background technique [0002] Lead-acid batteries are used in automobile starting, industrial energy storage and other fields, and are closely related to human life. As a product of the industrial revolution, automobiles have been used all over the world, and lead-acid batteries have been used as the power source for starting, ignition, and lighting of automobiles. The starting ability and life expectancy requirements are getting higher and higher, and the frequency of high-temperature use of vehicle-mounted lead-acid batteries is increasing, resulting in a sharp increase in the proportion of defects in lead-acid battery plate decay and failure, and plate decay is mainly used to support active materials. Grid corrosion. [0003] Lead-acid batteries for energy storage require a servic...
