Abstract
The application discloses a ground lock with battery charging safety monitoring function and a battery thermal runaway monitoring method, and relates to the field of battery safety state monitoring. The ground lock comprises a lifting device, a voiceprint sensing sensor, an infrared long-distance temperature sensor and a control mainboard. The voiceprint sensing sensor senses voiceprint data of a battery during charging of an electric vehicle above the lifting device, the infrared long-distance temperature sensor monitors the temperature of the battery during charging of the electric vehicle above the lifting device in real time, and the control mainboard controls the lifting state of the lifting device and can also determine whether the battery is in the early stage of thermal runaway according to the voiceprint data and the temperature. The application adds the battery charging safety monitoring function of the electric vehicle to the existing ground lock function, can find thermal runaway of the battery during charging in advance, and improves the charging safety of the electric vehicle.
