Storage battery liquid leakage on-line detection system and method

The invention relates to an on-line detection system and method for liquid leakage of a storage battery, and the system comprises a liquid induction belt which is fixedly connected to a combination position of a pole of a single storage battery and a battery cover, and is used for detecting the liquid leakage amount at the position of the pole and outputting the resistance variation; the information acquisition module is electrically connected to the liquid sensing belt and is used for judging the liquid leakage condition of the single storage battery and outputting a judgment result; the information acquisition module further comprises a matching sub-module which is used for receiving the resistance variation output by the liquid induction belt, converting the resistance variation into voltage and outputting the voltage after voltage matching. The collection module is in communication connection with the information acquisition module and is used for acquiring a judgment result of the information acquisition
