Description

Technical Field

[0001] The present invention relates to the technical field of battery pack detection, and in particular to a battery pack automatic plug-in detection system and method. Background Art

[0002] With the rapid development of new energy vehicles, battery packs, as the power source of new energy vehicles, have also developed rapidly, evolving into different types of battery packs. For example, CTP battery packs have the advantages of high energy density, long battery life, and low cost of use, and the market demand is strong. After the battery pack is produced, it needs to undergo a series of tests. The tests require the use of connectors to connect the battery pack and the test tooling. Traditionally, the connection is done manually, which has the following disadvantages:

[0003] 1. The battery pack has a large number of connectors, which need to be plugged in before testing and unplugged after testing, and the manual operation is inefficient; 2. The connectors and testing tools are plugged in tightly and frequently, which is labor-intensive and affects the testing efficiency; 3. After the plug-in is completed, the test needs to be started manually, which is cumbersome; 4. Manual plug-in poses a safety hazard of electric shock.
