Solution Approach 1:

The power supply system is segmented into multiple independent power paths, each serving specific function modules. The battery module is divided into multiple battery groups (first battery group, second battery group, etc.), with each group connected to different function modules through separate power paths. This segmentation allows independent control and selection of power paths, enhancing flexibility while managing complexity through modular organization.
