Battery monitoring system and method based on battery cycle data similarity analysis

The invention discloses a battery monitoring system and method based on battery cycle data similarity analysis. The system comprises a plurality of pieces of battery testing equipment, an upper computer, a loudspeaker, short message sending equipment, and a short message receiving terminal of a tester, wherein the battery testing equipment is used for testing the cycle performance of a battery, each battery testing equipment is connected with the upper computer and sends battery test data to the upper computer in real time, the short message sending equipment and the loudspeaker are respectively connected with the upper computer, and the upper computer is used for reading the battery test data, intercepting and normalizing the test data in the latest cycle range, taking the test data of the normal first cycle as a reference, carrying out similarity analysis on the test data of each new cycle, judging whether the test data of the new cycle is abnormal, and under the abnormal condition,sending an alarm through
