Abstract: Abstract:Distributed sensor networks can collaboratively collect multi-point operating parameters of power batteries, providing a data foundation for precise perception of health status. This article analyzes the core perception principle of distributed sensing networks, studies technologies such as voltage, temperature, and current acquisition, edge data preprocessing, health feature extraction and fusion, and online evaluation of battery status. A comparative experimental plan is proposed to improve the accuracy of power battery health status recognition, abnormal localization speed, and online monitoring reliability.
