Abstract

The invention discloses a method for testing the equi-voltage curve of a plate grid of a storage battery and relates to the field of storage batteries. The method is used for solving the technical problem that expected performance cannot be achieved during the design of the plate grid. According to the testing method disclosed by the invention, the plate grid is connected into a circuit of a testing device, a first testing point of a voltage measuring instrument is fixedly connected with the plate grid, a second testing point of the voltage measuring instrument tests voltages of different positions of the plate grid, test results are recorded, and the equi-voltage curve is drawn on a plate grid drawing. The test results can serve as an important basis for the design of the plate grid, so that the improvement on the design of the plate grid is facilitated, and the performance of products is improved.

Description

【Technical field】 [0001] The invention relates to a method for testing battery grids, in particular to a testing method for equal voltage curves of battery grids. 【Background technique】 [0002] The pole plates in the battery are composed of grids and active materials, both of which are key components that determine the capacity and life of the battery. The grid plays the role of conducting current and corrosion resistance in the battery, and plays an important role in the charging and receiving capacity, discharge performance and cycle life of the battery. In the traditional grid design, the lead consumption is first determined and then divided into several grids according to the product performance. The vertical ribs and horizontal ribs of the grid are designed differently to meet the product performance requirements. However, during the use of the battery, the changes in the electrical properties of the grid in the height and width directions are inconsistent, so there i...
