Abstract

The present application relates to a battery thermal runaway experiment device, which includes a box body, a uniform heater and an air circulation device. The uniform heater is arranged in the box for generating heat. The air circulation device is arranged in the box. The air circulation device is arranged opposite to the uniform heater at intervals, and is used to change the air flow direction in the box to make the heat in the box uniform. The battery thermal runaway experiment device provided in the present application accurately simulates the thermal runaway scenario induced by the overall uniform temperature of the battery to be tested, thereby improving the accuracy and reliability of the experimental results.

Description

technical field [0001] The present application relates to the field of battery safety, in particular to a battery thermal runaway experimental device and a system thereof. Background technique [0002] With the development of science and technology, power batteries have become common items in people's daily life and production. The power battery is prone to thermal runaway under certain inducing factors, thus causing safety accidents. Therefore, it has become an important topic to study the thermal runaway process of power batteries. [0003] At present, people's research on the process of battery thermal runaway is mainly through Accelerating Rate Calorimetry (ARC), adiabatic reaction heat energy meter (Vent Sizing Package 2, VSP2), Differential Scanning Calorimetry (Differential Scanning Calorimetry, DSC), cone calorimeter and other instruments to simulate the thermal runaway scene of the power battery, and conduct research on the heat production, jet, combustion and oth...
