Abstract

The invention, which belongs to the technical field of soft package battery testing, discloses a single soft package battery testing device and method. The testing device comprises a left sliding block and a right sliding block which are connected in a sliding manner, four upper pressing blocks with the same structures, charging and discharging testing connecting wires and an insulating anti-bulging clamp. Four upper pressing blocks are connected to the left sliding block or the right sliding block in a sliding mode through respective brackets, thereby realizing size adjustment of the testingdevice in an X direction and a Y direction. One end of each charging and discharging testing connecting wire is fixed at the position facing the corresponding upper pressing block on each rack and theother ends of the charging and discharging testing connecting wires are connected with testing equipment. The insulating anti-bulging clamp is arranged on the left sliding block and the right slidingblock; and a K-type thermocouple is adhered to the central point of the insulating anti-bulging clamp. On the basis of an integrated design, the steps of the testing method are simplified, the damagecaused by tab punching is avoided; and the compatibility with testing of soft package batteries with different sizes and tab arrangement modes is realized.

Description

technical field [0001] The invention relates to the technical field of pouch battery testing, in particular to a pouch battery unit testing device and testing method. Background technique [0002] The pouch battery refers to covering the liquid battery with a polymer shell. The pouch battery not only has the advantages of light structure weight and high energy density, but also has a small internal resistance of the pouch battery and has a flexible envelope structure design. The three-dimensional size and layout of the pouch battery can be adjusted according to the layout requirements, and it is safe High performance, therefore, widely used in new energy vehicles. [0003] Based on the high requirements for the safety performance and reliability of automobiles, the performance test of pouch batteries is becoming more and more important. At present, when testing pouch batteries, the method of punching tabs is often used. Firstly, the tabs are connected to the charge and dis...
