Embodiment 1

[0049] like figure 1 As shown, this embodiment provides a safety control method for a battery vibration test. The vibration test is performed on the battery by using a vibration device. The vibration device includes at least one clamp for clamping the battery. The safety control method includes the following steps:

[0050] S110. Acquire parameter information of the BMS system of the battery; the parameter information includes a thermal runaway signal, a maximum voltage and a minimum voltage, a total voltage, all cell temperatures and all cell voltages.

[0051] Among them, the BMS system of the battery can monitor the status of the battery in real time, including the voltage of the battery and the voltage and temperature of all cells. The BMS system can also monitor whether the battery has thermal runaway, and will report a thermal runaway signal when the battery has thermal runaway.

[0052] S120. Acquire status information of the battery; the status information includes the...

Abstract

The invention discloses a safety control method and a safety control system for a battery vibration test, and belongs to the technical field of batteries. The safety control method comprises the following steps: acquiring parameter information of a BMS system of a battery; acquiring the state information of the battery; acquiring laboratory environment temperature information; according to the parameter information, the state information of the battery and the laboratory environment temperature information, diagnosing the battery to obtain a diagnosis result; and according to the diagnosis result, selecting whether to loosen a clamp, turn off vibration equipment, give an alarm and spray water to the battery. According to the invention, in a battery vibration test process, the state and parameters of a battery are automatically monitored in real time, and when potential safety hazards exist in the battery, a clamp can be automatically loosened, so that the purpose of quickly detaching the battery from vibration equipment can be achieved; and compared with the prior art, in the whole test process, testers do not need to be on duty, and the personal safety of the testers can be protected.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a safety control method and a safety control system for battery vibration test. Background technique [0002] Vibration test is an important link in the process of battery product development to test the quality of battery products. In the prior art, the vibration test of the battery requires the use of a fixture to fix the battery on the vibration table of the vibration equipment, and the test personnel are required to be on duty throughout the entire test process and check the status of the battery in real time, so as to find out in time when the battery is in danger. . This test method cannot guarantee the safety of test personnel and equipment, and there is a great potential safety hazard. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a safety control method and a safety control system for battery vibration test, so as to improve t...
