Embodiment Construction

[0034] The embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the various embodiments in the present application and the various features therein may be arbitrarily combined with each other.

[0035] As mentioned above, due to the chemical reaction inside the pouch battery module, many gases will be generated, including flammable and explosive gases such as methane, and toxic gases such as carbon monoxide. Therefore, while applying the soft-pack lithium battery energy storage technology, it is also necessary to support the corresponding gas monitoring scheme to reduce safety accidents caused by gas leakage. However, in the related art, the pouch battery is only managed by the battery management system, and cannot effectively monitor the flammable and explosive gas of the pouch battery module.

[0036] In view of the above technical problems, the basic idea o...

Abstract

The invention discloses a soft package battery module and a manufacturing method thereof. In one embodiment of the invention, the soft package battery module comprises a soft package battery module body which comprises a soft package battery pack, a battery protection plate and a battery pack top plate; an optical fiber demodulator which is fixed on the battery pack top plate; and an optical fibergas sensor which is fixed at a position, close to the tab of the soft package battery in the soft package battery pack, on the battery protection plate and is connected with the optical fiber demodulator through the optical fiber of the optical fiber gas sensor. Real-time gas monitoring can be carried out on the independent soft package battery module, the signal interference resistance is high,the durability is good, the soft package battery module can be used in severe environments of high temperature, high voltage and the like, a sensitive and accurate monitoring effect is achieved, and safety accidents caused by toxic and harmful gas leakage of the soft package battery module can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a soft pack battery module and a manufacturing method thereof. Background technique [0002] Due to the advantages of good safety performance, light weight, large module capacity, and flexible technical solutions, soft pack battery modules are widely used in the field of new energy and energy storage. However, when there is a safety hazard in the soft pack battery module, due to the internal chemical reaction, flammable and explosive gases such as methane and toxic gases such as carbon monoxide will be generated. Therefore, while applying the soft pack battery, it is also necessary to support the corresponding gas monitoring scheme to reduce safety accidents caused by gas leakage. [0003] In the related art, the soft pack battery only manages the battery through the battery management system, and cannot effectively monitor the flammable and explosive gas. SUMMARY OF THE INV...
