Abstract

The invention provides a battery diaphragm embedded with an optical fiber sensor, comprising: a battery diaphragm and a sensing-increasing optical fiber structure embedded in the battery diaphragm, and the sensing-increasing optical fiber structure includes a plurality of optical fiber sensors. The optical fiber sensor-embedded battery diaphragm of the present invention embeds the optical fiber sensor in the battery diaphragm, and can monitor the temperature inside the battery and the expansion of the casing, thereby improving the understanding and management of the battery state.

Description

technical field [0001] The invention relates to the application of the optical fiber sensing technology in the field of battery safety, in particular to the application of the optical fiber sensing technology in the battery diaphragm. Background technique [0002] With its unique advantages of environmental protection, energy saving and emission reduction, electric vehicles have become an important way to solve the two major problems of environmental pollution and energy crisis. As the power source of electric vehicles, the performance of batteries is of great significance to the safety and development prospects of electric vehicles. Therefore, it is very important to realize real-time monitoring of the working status of batteries. Traditional battery safety monitoring mainly focuses on the overall temperature change and deformation of the battery, while short circuit, overcharge and material degradation inside the battery will lead to overheating inside the battery and expa...
