Abstract

Disclosed are a soft pack battery module and a manufacturing method thereof. In an embodiment of the present application, the pouch battery module includes: a pouch battery module body, including a pouch battery pack, a battery heat conducting separator, and a battery pack top plate, and adjacent pouch batteries in the pouch battery pack Separated by the battery heat-conducting separator; the optical fiber demodulator is fixed on the top plate of the battery pack; the optical fiber liquid leakage sensor is fixed on the side of the battery heat-conducting separator surface and connected with the optical fiber through its optical fiber Modem connection. The embodiment of the present application can not only monitor the ground leakage in real time for the independent pouch battery module, but also has strong anti-signal interference performance and good durability, can be used in harsh environments such as high temperature and high voltage, and has sensitive and accurate monitoring effect , can greatly reduce the safety accidents caused by the leakage of the pouch battery module.

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, the pouch battery module has gradually been widely used in the field of new energy and energy storage. However, the pouch battery may still leak when it is working, and when the leakage is serious, it will cause safety accidents such as battery explosion. Therefore, while realizing the soft-pack battery, it is also necessary to provide a liquid leakage monitoring solution for the soft-pack battery to monitor the battery condition in real time and reduce safety accidents caused by battery leakage. [0003] In the related art, the pouch battery only manages the battery through the battery management system, and cannot effectively monitor the battery leakage. Contents...
