Title:
INTELLIGENT HEALTH-MONITORING METHOD AND SYSTEM FOR BIDIRECTIONAL LITHIUM-ION BATTERY
Document Type and Number:
WIPO Patent Application WO/2024/066052
Kind Code:
A1
Abstract:
Disclosed in the present invention are an intelligent health-monitoring method and system for a bidirectional lithium-ion battery. The method comprises: collecting, on the basis of a sensor, historical charging and discharging data of a bidirectional lithium battery within different time periods, uploading the data to a cloud database, and simulating real-time charging and discharging data of the bidirectional lithium battery on the basis of a digital twin system; determining historical fault data in the historical charging and discharging data, and generating sample fault data on the basis of a conditional generative adversarial network and a preset data label; according to the sample fault data, performing training to obtain a fault prediction model, and performing fault prediction on the real-time charging and discharging data, so as to obtain a fault prediction result; and if the fault prediction result indicates that there is fault data in the real-time charging and discharging data, classifying the fault data, determining corresponding fault category information, and feeding back a fault category in the digital twin system. By means of the present invention, the health state of a bidirectional lithium-ion battery can be monitored, and online early warning is facilitated.
