NOVELTY - The utility model claims a lithium battery thermal runaway pre-warning system based on graphene MEMS gas sensor, comprising a graphene MEMS gas sensor, a data pre-processing module, a main control chip, a wireless transmission module, a control terminal; The utility model through MEMS multiple gas sensor real time collecting gas data signal of lithium battery surrounding environment to calculate the concentration value, judging whether the lithium battery thermal runaway, once the thermal runaway caused fire, immediately starting control terminal of the fire control device control thermal runaway expansion, the risk caused by thermal runaway is reduced to the lowest, it can sensitively detect the lithium battery thermal runaway fire risk and take pre-warning measures in time.
