Abstract
A multiparameter integrated online monitoring system and method for at least one energy storage battery based on Fiber Bragg grating (FBG) are provided. The system includes multiple sensors based on the FBG including a temperature, a strain, a pressure, a current, a voltage and a gas sensor, a FBG demodulator, a computer, and transmission optical fibers. The multiple sensors are connected in series on one transmission optical fiber and can be multiplexed to establish the multiparameter integrated and distributed optical fiber sensing monitoring network from single battery to module, or from single battery to cluster, or from single battery to energy storage system. The system has advantages of simple structure, small occupied space, anti-electromagnetic interference, corrosion resistance, multiparameter integration and distributed simultaneous measurement. It can monitor the status of the multiple parameters in real time, so as to judge the charge, health status and remaining life of the battery.
