Gas production rate measurement and gas collection device for thermal runaway process of lithium ion battery

The invention, which belongs to the technical field of safety control, particularly relates to a gas production rate measurement and gas collection device for the thermal runaway process of a lithiumion battery. The device comprises a pressure explosion-proof container, a heating device, a battery suspension device, an inert gas circulation device, a battery charge and discharge module, a detection device, an explosion-proof pressure relief module, a control system, and a gas collection module. Compared with the prior art, the gas production rate measurement and gas collection device has thefollowing beneficial effects: gas production rate measurement and gas collection are carried out on gas generated by the thermal runaway triggered by the high-temperature, over-charging, and over-discharge problems of the lithium-ion battery; the temperature and voltage changing situations of the thermal runaway process of the lithium ion battery are monitored in real time; and the reliable data support is provided for the
