Research of Acoustic Emission Testing Method to Detected the Large Scale BES

AE testing is one of the most effective means to detected battery performance, and routine maintenance and testing work has a very important significance. Through domestic and international testing standards, and combined with the actual needs of the scene, a practical capacity storage battery string field test method has been concluded. The current test method has been used in the field, and the specific test details perfect the test in future capacity. The capacity of the proposed test method has practical guidance, not only for energy storage battery field maintenance work, but also for the safe and efficient operation of energy storage power station. It is based on the adaptive changing principle of the discovering level of detection of the useful signal while performing non-standard parameters valuation of danger degree of acoustic emission impulse sources.
