Description

Technical Field

[0001] The present invention relates to the technical field of battery detection equipment, and in particular to a method and system for matrix control of external connected devices. Background Art

[0002] The rapid development of new energy vehicles has driven innovation in power battery technology. As a core component of new energy vehicles, power batteries' performance directly impacts vehicle range, safety, and service life. Power batteries are temperature-sensitive, significantly impacting not only their overall performance but also posing a direct threat to their service life and safety. To ensure the reliability and stability of power batteries in various complex environments, rigorous environmental testing is essential. High-temperature testing simulates battery operation in high-temperature environments to assess their heat resistance and thermal stability; low-temperature testing simulates battery operation in low-temperature environments to evaluate their low-temperature starting performance and discharge capacity. Temperature testing is crucial for ensuring proper operation of batteries in diverse climates. Humidity testing simulates battery operation in humid environments to assess their moisture resistance and corrosion resistance. High humidity can easily lead to moisture contamination of internal battery components, impacting performance and even causing safety incidents. Much of the temperature and humidity data for these simulated environments is based on actual battery measurements, which are both voluminous and complex. Traditional processing methods include: one is to disassemble the data, edit the corresponding control steps based on the disassembled data in the step test process, and realize the temperature and humidity settings through the control steps. This method requires editing a large number of control steps; another method is to control the temperature and humidity separately by the temperature and humidity control equipment. This method will cause the battery detection equipment and the temperature and humidity control equipment to be unable to work together. A test needs to control both devices at the same time. These problems have a great impact on the simulated environment test. Summary of the Invention
