[0002] The new energy automobile battery detection tool test bench integrates core functions such as electrical performance detection, safety performance testing, and working condition simulation. Through charge and discharge equipment, temperature control systems, mechanical tooling, and high-precision sensors, it realizes accurate measurement and monitoring of battery voltage, current, capacity, internal resistance, and other parameters. It can simulate extreme working conditions such as overcharging, over-discharging, high and low temperatures, and vibration, while collecting and analyzing data in real time. It is widely used in battery research and development, production quality inspection, and after-sales maintenance, providing key support for improving battery performance, ensuring safety, and promoting technology iteration.

[0003] During the production and research and development of new energy automobile batteries, it is necessary to detect the batteries for subsequent production processes. During this process, detection test benches are often used. Existing new energy automobile battery detection tool test benches cover single / module detection, battery pack comprehensive performance testing, environmental simulation, safety performance verification, working condition aging test, and automatic production line detection. Through high-precision measurement, energy recovery, and intelligent control technology, the detection of battery full-cycle performance, safety, and reliability is realized. However, there is a lack of battery detection tool test benches that can disassemble and assemble different batteries according to different needs. It is not possible to flexibly combine single battery packs for detection according to detection needs. When simulating battery pack vehicle detection, the entire battery pack needs to be combined for detection, making it difficult to simulate the cooling and operation detection of battery packs according to the combination needs. There is a problem of high overall cost and low efficiency, and the heat dissipation efficiency is low when simulating driving conditions. Therefore, a new energy automobile battery detection tool test bench is proposed. SUMMARY
