Description

Technical Field

[0001] The utility model relates to the technical field of battery testing, in particular to a comprehensive testing device for battery safety performance. Background Art

[0002] Power batteries, with their excellent properties such as high operating voltage, high energy density, and low self-discharge, are a key development project in my country's new energy sector and are being rapidly promoted and applied in areas such as electric vehicles. As power batteries increase in size, energy density, and operating environments become more severe, battery safety risks are becoming increasingly serious. Consequently, numerous scholars at home and abroad have conducted research on battery thermal characteristics and thermal runaway to deepen their understanding of the root causes of thermal runaway and fires, and to identify the main causes of battery unsafety. Furthermore, quantitatively evaluating the thermal safety performance of battery cells and modules, and quantitatively clarifying the manifestations and hazards of special phenomena such as thermal runaway, provide guidance for the development of high-safety battery systems, reduce the likelihood of battery safety accidents, and provide theoretical basis and technical support for the industrial application of large-scale batteries.

[0003] The Chinese authorized publication number is CN 209311655 U, a comprehensive battery safety performance test device. The bottom of the test box is wedge-shaped, with slide grooves on both sides of the wedge-shaped bottom. The battery can be easily moved up the wedge-shaped bottom under the fixation of the battery clamp. After moving to the specified position, the positioning rod is inserted into the horizontal groove in the slide groove to prevent the battery from moving. After the test is completed, the positioning rod is removed, and the battery can be moved downward, reducing the trouble of manual battery handling.

[0004] However, this patent still has certain shortcomings when in use. When the current test device clamps the battery, since the battery shell is mostly curved, it is easy for the battery to move or fall off during the test, which may damage the test equipment, thereby causing the test equipment to be unable to accurately measure the battery parameters, and it cannot flexibly clamp batteries of different shapes and sizes, which brings great inconvenience to the testing work. In addition, the existing test device does not have a protective device for the battery, and the high pressure during clamping may cause damage to the battery. Utility Model Content
