Pure electric vehicle lithium battery pack power conversion efficiency performance test assembly

Abstract

The invention relates to the technical field of automobile lithium battery packs. The invention particularly relates to a pure electric vehicle lithium battery pack power conversion efficiency performance test assembly. The lower surface of a workbench is fixedly connected with a base. A through cavity is formed in the surface of the workbench. A rotating shaft is rotationally connected to the interior of the workbench and located in the through cavity; one end of the rotating shaft is fixedly connected with a threaded column; the other end of the threaded column is rotationally connected witha clamping seat; the inner wall of the workbench is fixedly connected with a supporting column, the inner wall of the workbench is fixedly connected with a bearing seat, one side of the bearing seatis movably connected with a telescopic column; the outer surface of the telescopic column is sleeved with a telescopic spring; one end of the telescopic column is fixedly connected with a jacking column; and the other end of the jacking column is movably connected with a mounting plate. According to the invention, lithium battery packs with different diameters and sizes can be fixed, the lithium battery packs cannot be damaged, the subsequent test of the lithium battery packs is ensured, and the use is more convenient.

Description

technical field [0001] The invention relates to the technical field of lithium battery packs for automobiles, in particular to a power conversion efficiency performance test component of lithium battery packs for pure electric vehicles. Background technique [0002] The rapid development of the automobile industry has promoted the development of important industries such as machinery, energy, rubber, and steel, but at the same time it is increasingly facing serious problems of environmental protection and energy shortage. In order to solve these problems, electric vehicles have achieved considerable development and great technological progress. At the same time, electric vehicles have made great progress in battery systems, electric drive systems, and vehicle control. In electric vehicles, the battery system is a key core component. As a power source, the battery requires high energy density, high output power density, wide operating temperature range, long cycle life, no me...

Problems solved by technology

[0003] Before the lithium battery pack is used, it is often necessary to test its power conversion efficiency. During the test, the staff usually take the lithium battery pack by themselves, then place it on the side of the test bench, and then test it, so that not only The operation is more troublesome, and the lithium battery pack is not fixed, which affects the test effect, and the workload is also relatively large. Therefore, in view of this, research and improvement are made for the existing structure and defects, and a pure electric vehicle lithium battery is provided. Group power conversion efficiency performance test components, in order to achieve more practical value
