[0002] Since there is no gas detection solution proposed for a single battery module, when the lithium iron phosphate battery integrated in the battery module is damaged or leaks, flammable and explosive gases such as methane and acetylene appear; hydrogen fluoride, carbon monoxide, etc. When the toxic gas leaks, the corresponding management system inside the energy storage container cannot detect in real time
This will not only bring hidden dangers to the personal safety of the inspection personnel, but also cause major safety accidents such as combustion or explosion, resulting in environmental pollution and large economic losses. Based on this, this application proposes a gas for a single battery module Detection method

The invention discloses a gas detection method for a single battery module. The gas detection method includes a battery module and a detection device; the battery module is composed of an energy storage battery module; the energy storage battery module is an energy storage battery pack of an internal integrated lithium battery; and the detection device is composed of a gas detection device, a bypass pipeline and a main pipeline. The invention has the following beneficial effects: the gas detection method for the single battery module is reasonable in design, and monitors an internal gas flow in real time when the single battery module works; when the lithium battery is abnormal, whether flammable and explosive gas, and poisonous gas are generated may be detected; by controlling a gas flowentering an inside of the detection device, the response speed of the whole gas detection device is very fast, so that a signal may be transmitted to a central control management system quickly, to implement an early alarm function. Not only can the personal safety of an inspection personnel be effectively guaranteed, but also the occurrence of a safety accident can be prevented and the huge economic loss caused by the safety accident is reduced.
Description
technical field [0001] The invention relates to a gas detection method, in particular to a gas detection method for a single battery module, and belongs to the technical field of energy storage battery module monitoring. Background technique [0002] Since there is no gas detection solution proposed for a single battery module, when the lithium iron phosphate battery integrated in the battery module is damaged or leaks, flammable and explosive gases such as methane and acetylene appear; hydrogen fluoride, carbon monoxide, etc. When the toxic gas leaks, the corresponding management system inside the energy storage container cannot detect it in real time. This will not only bring hidden dangers to the personal safety of the inspection personnel, but also cause major safety accidents such as combustion or explosion, resulting in environmental pollution and large economic losses. Based on this, this application proposes a gas for a single battery module Detection method. Cont...
