Power battery detection method, system and device and medium

Abstract

The invention discloses a power battery detection method, system and device and a medium. The method comprises the following steps: acquiring a real vehicle signal simulated by a rapid control prototype system; outputting the real vehicle signal to a power battery control management system, and obtaining an output result fed back by the power battery control management system; detecting a physical signal in the power battery; and uploading the output result and the physical signal to an upper computer, and carrying out defect detection on the output result and the physical signal. According to the method, the detection of the power battery is developed based on the rapid control prototype system, the comprehensive test of the product quality of the power battery system is realized through the automatic test sequence, and the inspection result is automatically output, so that the detection efficiency can be effectively improved, and the safety of the battery is ensured. The power battery detection method, system and device can be widely applied to the technical field of automobiles.

Description

technical field [0001] The present application relates to the technical field of automobiles, and in particular, to a power battery detection method, system, device and medium. Background technique [0002] As the energy storage device of the whole vehicle, the power battery directly determines the cruising range and safety performance of the whole vehicle. Based on the electrochemical characteristics of the power battery, in the process of manufacturing, transportation, storage and use, if the quality is poor, it is easy to cause explosions and fires, etc. Security risks. Therefore, in the process of automobile production, it is necessary to check the quality of the power battery to confirm its quality status and ensure its performance and safety performance. [0003] At present, OEMs and parts suppliers mainly use CAN or other communication tools to read the power battery software version, status detection and other information through the host computer, but this method c...

AI Technical Summary

Problems solved by technology

[0003] At present, vehicle manufacturers and parts suppliers mainly use CAN or other communication tools to read information such as power battery software version and status detection through the host computer, but this method cannot realize incentive testing, control strategy of power battery management system, Electrical performance cannot be effectively guaranteed

However, large-scale EOL testing equipment is used to test the power battery system. Although the power battery system can be tested for status detection, insulation withstand voltage test, etc., the equipment used needs to be integrated in the cabinet, which occupies a large area and cannot be carried. Under the environment, it is impossible to quickly and accurately check the power battery, so the use effect is severely limited
