The invention relates to the field of battery management, and the embodiment of the invention provides a method for inhibiting thermal runaway of a lithium battery. The method comprises the steps of obtaining thermal runaway parameters of the lithium battery; and according to the relationship between the thermal runaway parameters and preset safety threshold values, protection threshold values andfault threshold values, executing a corresponding inhibition measure. The thermal runaway parameters comprise a battery voltage, and selectively comprise a battery internal pressure value and/or a battery temperature; a plurality of safety thresholds, a plurality of protection thresholds and a plurality of fault thresholds are provided and correspond to the selected thermal runaway parameters. Meanwhile, the invention further provides corresponding equipment for inhibiting thermal runaway of the lithium battery and an electric vehicle. According to the embodiment provided by the invention, the possibility of thermal runaway of the lithium battery under an abuse condition can be effectively reduced.
