Problems solved by technology
[0003] At present, the test methods for the performance of thermal insulation materials in the market are relatively rough. Place the thermal insulation material directly on the sample rack, place a high-temperature spray gun at the bottom of the rack, use the high-temperature spray gun to heat the thermal insulation material, and then use a hand-held thermocouple to measure To detect the temperature on the upper surface of the heat insulation material, many values cannot be quantified in the current test method, the surrounding operating environment is not controlled, and the heat insulation material is not fixed, making the test results unstable, and many results are far from the time. Efficiently derive the thermal insulation performance of insulation materials through existing tests

Description
technical field [0001] The invention belongs to the technical field of performance detection, and in particular relates to a device and method for testing the thermal insulation performance of a thermal insulation material for batteries. Background technique [0002] As the proportion of new energy vehicles in the market continues to increase, and there are also more and more cases of self-ignition and self-explosion of new energy vehicles, OEMs are also paying more and more attention to battery thermal runaway. Insulation material is a common method for OEMs to prevent continuous thermal runaway. The principle is that when one of the cells is thermally out of control, the material in the middle can prevent the heat generated by the explosion of the thermally runaway battery from being transferred to the next cell, thereby preventing the phenomenon of continuous thermal runaway. [0003] At present, the test methods for the performance of thermal insulation materials on the...
