As the core safeguard for stable operation of spacecrafts, the satellite power system has reliability that directly determines the sucess of orbit missions.Battery safety constitutes the ultimate line of defense during satellite energy crises.To evaluate power system security under abnormal conditions,a mathematical model for battery safety strategies has been developed,incorporating mechanisms such as over-voltage protection,current limiting, and hierarchical energy crisis management.And a hierarchical threshold calculation method for energy crisis is proposed. This model is integrated into the simulation framework of remote sensing satellite power systems. The developed approach enables real-time adjustment of satellite load, battery output current, and charging voltage based on battery status monitoring, while assessing the impact of energy crises under abnormal conditions. The results demonstrate that when battery state of charge falls below 15% or over-discharge protection is triggered, hierarchical management strategies can restore normal operations 1-2 orbital periods in advance. Hierarchical energy crisis management effectively shortens satellite energy anomaly persistence duration.
