Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, specifically to a testing device for energy storage products. Background Technology

[0002] In the battery pack production line, it is necessary to test key parameters such as the open-circuit voltage of the cells under no-load conditions, and adjust the position of the battery pack according to the polarity of the cells.

[0003] Chinese patent CN213813886U discloses an OCV testing device. This device consists of a base, tray, frame kit, and probe module. Because the positive electrode probe kit is divided into voltage probe and current probe sleeve, voltage detection and current detection are not integrated into the same component, which can improve the accuracy of OCV detection and reduce the likelihood of misjudgment during subsequent battery performance analysis. In addition, since there are guide holes on the top plate, the guide holes play a guiding role, and the voltage probe and current probe sleeve are located in the guide holes, which can ensure stable contact between the positive electrode probe kit and the negative electrode probe with the battery. However, this testing device is difficult to meet the continuous testing requirements of mass-produced battery packs.

[0004] Based on this, the present invention designs a testing device for energy storage products to solve the above problems. Utility Model Content

[0029] In this invention, the feeding conveyor 1, the testing mechanism 2, and the positioning and transfer mechanism 3 work together to continuously test the voltage internal resistance of the battery pack 9 and simultaneously measure the polarity of the battery pack 9. Then, the sorting and adjusting discharge mechanism 4 places the battery packs 9 with voltage internal resistance values ​​in the same range onto different discharge conveyors 5, achieving automated sorting and discharge of battery packs 9 of different qualities. Furthermore, the orientation of the battery packs 9 is adjusted during the transfer process to ensure that the polarity of all battery packs 9 is consistent.
