Embodiment 1

[0042] see figure 1 , is a schematic flowchart of a battery system detection method provided in Embodiment 1 of the present invention, and the method includes steps S101 to S104 .

[0043]Specifically, the battery system detection method is a comprehensive test method of temperature and humidity, vibration, and charge-discharge stress on the same time axis. The comprehensive test method of the same time axis refers to the comprehensive use of temperature and humidity test equipment with linkage function, vibration test equipment, charge and discharge test equipment and other equipment with linkage function. Apply temperature, humidity, vibration and electrical stress conditions to form a complete test method.

[0044] see figure 2 , is a schematic diagram of the connection between the temperature and humidity test equipment, vibration test equipment, charge and discharge test equipment provided in the first embodiment of the present invention and the battery system to be te...

Embodiment 2

[0074] see Image 6 , is a schematic structural diagram of a battery system detection device provided in Embodiment 2 of the present invention. The temperature stress application module 201 is used to send a temperature stress signal corresponding to a preset temperature to the temperature and humidity test equipment, so that the temperature and humidity test equipment controls The internal temperature of the battery system to be tested reaches the preset temperature;

[0075] The humidity stress applying module 202 is configured to, in response to the temperature balance signal sent by the battery system to be tested, send a humidity stress signal corresponding to the preset ambient humidity to the temperature and humidity testing device, so that the temperature and humidity testing device controls the current humidity to the preset ambient humidity;

[0076] The vibration stress applying module 203 is used to send the vibration stress signal corresponding to the preset vibr...

Embodiment 3

[0096] see Figure 7 , is a schematic structural diagram of a battery system detection terminal device provided in Embodiment 3 of the present invention. The battery system detection terminal device of this embodiment includes: a processor 301, a memory 302, and a computer program stored in the memory 302 and executable on the processor 301, such as a battery system detection program. When the processor 301 executes the computer program, the steps in each of the foregoing battery system detection method embodiments are implemented. Alternatively, when the processor 301 executes the computer program, the functions of the modules / units in the foregoing device embodiments are implemented.

[0097] Wherein, if the modules / units integrated in the battery system detection terminal equipment are implemented in the form of software functional units and sold or used as independent products, they may be stored in a computer-readable storage medium. Based on this understanding, the pre...

Abstract

The invention discloses a battery system detection method and device, terminal equipment and a storage medium. The method comprises the steps: transmitting a temperature stress signal corresponding tothe preset temperature to temperature and humidity test equipment, and enabling the temperature and humidity test equipment to control the internal temperature of a to-be-tested battery system to reach the preset temperature; responding to the temperature and humidity stable state signal transmitted by the to-be-tested battery system and sending a vibration stress signal corresponding to the preset vibration road spectrum condition to vibration test equipment so that the vibration test equipment simulates a driving condition corresponding to the vibration road spectrum condition; responding to the driving state signal transmitted by the to-be-tested battery system and sending an electric stress signal corresponding to the preset electric stress profile condition to charging and discharging test equipment so that the charging and discharging test equipment controls the to-be-tested battery system to simulate the battery working condition operation under the driving working condition. The problem that the battery system is not comprehensively evaluated under a single stress condition can be effectively solved, and the real characteristics of the battery system can be accurately andcomprehensively reflected.

Description

technical field [0001] The present invention relates to the technical field of battery systems, and in particular, to a battery system detection method, device, terminal device and storage medium. Background technique [0002] At present, the testing specifications and standards for the reliability, safety and electrical performance of the battery system are mainly single-factor loading methods; the comprehensive stress conditions under actual driving conditions are lacking. Only evaluating the characteristics of the battery system under the test conditions of a single stress cannot fully reflect the actual performance of the vehicle. However, in the actual driving process, the battery system products that have multiple elements independent of each other and pass the series inspection often have a high failure rate after being subjected to temperature and humidity, vibration and electrical stress at the same time. SUMMARY OF THE INVENTION [0003] The embodiments of the p...
