Abstract

The invention relates to a heat insulation experiment bin and a thermal runaway experiment method.The heat insulation experiment bin comprises a bin body, a heating device, at least one first temperature sensor and at least one second temperature sensor, the bin body comprises an inner shell and an outer shell, and an interlayer cavity is formed between the outer shell and the inner shell; the inner shell is provided with an experiment inner cavity, the experiment inner cavity is configured to be used for placing a target object, the bin body is provided with a bin opening communicated with the experiment inner cavity, the bin opening is provided with a bin door, a heating device is arranged in the interlayer cavity, at least one first temperature sensor is arranged in the experiment inner cavity, and a second temperature sensor is arranged in the experiment inner cavity. The first temperature sensor is configured to be used for acquiring temperature information of a target object, the at least one second temperature sensor is arranged in the experiment inner cavity, and the second temperature sensor is configured to be used for acquiring environment temperature information of the experiment inner cavity. Therefore, the thermal runaway scene can be effectively simulated, and the existing experimental research requirements are met.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to an adiabatic experiment cabin and a thermal runaway experiment method. Background technique [0002] Since the invention of lithium cobalt oxide batteries in the early 1980s, the continuous advancement of lithium battery technology has made transportation electrification possible. At the same time, the demand for lithium batteries from new energy vehicles (trams) has further accelerated the development of lithium batteries in the direction of high specific energy. Rapid development. At present, the energy density of the world's mainstream new energy vehicle systems is above 150W / kg. In order to meet the development needs of new energy vehicles, the energy density of lithium battery cells needs to reach 350W / kg, and the energy density of the system is 280W / kg. Therefore, it is necessary to strengthen the analysis of the causes of new energy vehicle fires and the understan...
