This paper primarily relies on a laboratory thermal runaway experimental platform to simulate lithium battery thermal runaway scenarios in a semi-sealed gas chamber for early warning detection. During the experiments, overcharging and overheating conditions were used to replicate fault scenarios that may occur in actual battery operation, while collecting data on voltage, surface temperature, and gas sensor resistance. Four types of gas sensors were selected for this study, and a sensor deployment method was designed and implemented on the thermal runaway experimental platform. After conducting the experiments, the four stages of lithium battery thermal runaway were validated, and the response data of the gas sensors were collected to analyze their early warning performance and deployment methodology.

摘要

This paper primarily relies on a laboratory thermal runaway experimental platform to simulate lithium battery thermal runaway scenarios in a semi-sealed gas chamber for early warning detection. During the experiments, overcharging and overheating conditions were used to replicate fault scenarios that may occur in actual battery operation, while collecting data on voltage, surface temperature, and gas sensor resistance. Four types of gas sensors were selected for this study, and a sensor deployment method was designed and implemented on the thermal runaway experimental platform. After conducting the experiments, the four stages of lithium battery thermal runaway were validated, and the response data of the gas sensors were collected to analyze their early warning performance and deployment methodology.
