An intelligent current sharing function control method and system for power devices used in automobiles

Abstract

This invention proposes an intelligent current sharing function control method and system for automotive power devices, belonging to the field of current sharing function control technology. It collects data from each parallel power device using a pre-set sensor group, performs current health analysis on the parallel power devices based on the collected data, and generates a current health profile based on the current health analysis data. It then generates adjacent health profiles based on these profiles, analyzes and determines the status of adjacent devices based on these profiles, and performs current distribution analysis and control based on the adjacent device status analysis and determination information. Finally, it performs current sharing analysis and control based on the current distribution control data, obtaining device current sharing analysis and control data. This invention achieves precise matching between the health status of parallel power devices in automobiles and load distribution, balancing dynamic current sharing effect and long-term system reliability, effectively avoiding device overload premature aging and resource waste.
