Abstract

The invention discloses an anti-explosion valve which is arranged on a battery box body and comprises a valve body, a pressure relief mechanism movably arranged on the valve body, a detecting switch in contact with the pressure relief mechanism in the normal state; and when the pressure value in the battery box body is greater than the set anti-explosion pressure value, the pressure relief mechanism is separated from the detecting switch, and the detecting switch outputs a signal and transmits the signal to a control system for early warning. According to the anti-explosion valve, the detecting switch is arranged in the valve body, and the pressure relief mechanism is cooperated with the detecting switch to realize the early warming purpose and easily meet the safety standards of various new energy automobiles.

Description

technical field [0001] The invention relates to the technical field of new energy safety, in particular to an explosion-proof valve used in new energy electric vehicles. Background technique [0002] Under the trend of electrification of automobiles in recent years, the volume of electric vehicles in my country has grown rapidly, but with some electric vehicle fires and explosion accidents, the safety of electric vehicles has also been paid more and more attention, and has gradually become the focus of consumers. The focus is also the foundation for the sustainable and healthy development of the new energy automobile industry. It is clearly mentioned in the "Safety Requirements for Power Batteries for Electric Vehicles" standard: "When the battery thermal runaway occurs, the battery system will not fire or explode within five minutes to ensure that passengers have sufficient time to escape"; the national mandatory standard " The Safety Requirements for Electric Vehicles main...
