Technical Field

[0001] The utility model belongs to the field of automobile battery detection devices, and specifically relates to an aging function detection device for an automobile BMS. Background Art

[0002] With the attention paid to clean energy issues by people, the development of electric vehicles has received unprecedented attention. As one of the three major components of new energy vehicles, the battery pack has also attracted much attention. The battery pack mainly consists of a housing made of metal material, battery cells, and a battery management controller. The Battery Management System (BMS) can detect the voltage of each single battery cell and the temperature of each battery module, and can prevent abnormal conditions such as overvoltage, overcharge, over-discharge, and over-temperature of the battery pack. With the development of electric vehicles, many functions have been gradually added, such as leakage current detection, battery balancing management, and calculation of the remaining capacity (SOC), etc. As one of the core components of new energy vehicles, the quality monitoring and performance testing of BMS have become an indispensable part.

[0003] The BMS system is relatively complex and consists of thousands of components, and the control circuit or functional circuit is composed of different electronic components. After the BMS is manufactured, a complete product has been formed and can play the value of the product. However, various problems often occur during practical use. It is found that the vast majority of problems can occur in a short time. Therefore, corresponding aging equipment is made to screen in advance, leaving the problems in the factory and submitting the products without problems to customers to ensure that the products given to users are reliable or have fewer problems. This is the significance of product aging. Long-term aging testing can expose the reliability of production processes, electronic components, and designs in advance, and further improve product performance.

[0004] The defect of the existing technology is that the existing BMS aging system targets a single module and has a relatively single function test, and cannot perform aging detection on the entire BMS system. Summary of the Invention

[0005] Aiming at the problem that the existing BMS aging system targets a single module and has a relatively single function test and cannot perform aging detection on the entire BMS system, the utility model provides an aging function detection device for an automobile BMS.

[0007] An aging function detection device for an automobile BMS includes an intelligent control main board, a high-voltage power supply module, and an insulating housing;

[0008] The intelligent control module analyzes the collected data to judge whether the BMS is abnormal, and sends the error data to the upper computer through CAN;

[0009] The high-voltage power supply module provides a high-voltage load for the BMS system;

[0010] Inside the insulating housing, the intelligent control main board and the high-voltage power supply module are separately installed. The intelligent control main board is built-in with an intelligent control module.

[0012] Further, the intelligent control main board is installed above the bottom cover.

[0013] Further, the high-voltage power supply module is installed on the right cover and is arranged at an interval from the intelligent control main board.

[0014] Further, the whole insulating housing is made of a high-insulation and static-resistant material.

[0015] Further, the output port of the high-voltage power supply module uses a high-voltage insulating joint, and the high-voltage insulating joint is arranged on the back cover. The control circuit on the aging tooling is connected to the high-voltage insulating joint to switch the power supply of the whole system.

[0016] Further, the intelligent control module processes the load CC signal, the relay analog load, the PWM signal, and the analog signal input, controls the high-voltage output, and communicates with the BMS product.
