Abstract
Description
Technical Field
[0001] The utility model relates to the field of power battery detection, in particular to an insulating detection device for the bottom of a module. Background Art
[0002] With the rapid development of the new energy industry, the role of battery systems in energy supply has become increasingly important. Compared with traditional energy sources, battery systems have the advantages of low noise, high energy utilization efficiency, and easy access, so they are highly favored in the fields of energy storage and vehicle manufacturing.
[0003] Compared with traditional energy supply methods, new energy is slightly inferior in terms of insulation safety performance. Among them, power batteries, as the main energy supply body, their insulation safety design has always been an important part of product design; modules, as the basic units of power batteries, their good insulation performance is also an important guarantee for the insulation safety of vehicle-mounted batteries or energy storage systems; module insulation detection needs to be achieved by measuring the conductivity and insulation resistance value between the positive and negative poles and the outer shell of the insulation area. The key area lies in the bottom of the module, mainly because the bottom of the module directly contacts electrical components such as metal boxes or heating films, and the severity of its insulation failure is higher. Therefore, the insulation detection of the bottom of the module is the focus of ensuring the safety of battery products. However, there are the following problems in actual production:
[0004] 1. The insulation detection of the bottom of the module usually requires a metal platform as the detection carrier. During the whole process of stacking, assembling, and welding of the module, the bottom tray structure must be made of insulating material. For insulation detection, an additional station needs to be set up and a test platform needs to be installed. Traditional test platforms require additional mechanisms and connection programs, resulting in high costs and additional consumption of human resources or kinetic energy.
[0005] 2. The purpose of module insulation detection is to screen out modules with damaged bottoms at the bottom of the module to avoid insulation failure safety accidents flowing into the back end. Foreign objects may fall during the long-term operation of traditional test platforms and cannot be manually confirmed. If foreign objects adhere, it will cause misjudgment to modules with normal insulation.
[0006] 3. Traditional test platforms use a metal platform as the detection carrier to screen for damage to the flat area at the bottom of the module through insulation detection, but the inclined areas at the intersections of the thickness, width, and height of the battery cells at the edge positions cannot be detected. If there is damage, there is a risk of creepage in a vibrating environment. Content of the Utility Model
