The power consumption of the spacecraft may be affected by many factors, such as multiple working modes, large load power, the alternation of shadow and light, slow charging and fast discharging. Too much task planning may lead to the risk of over discharge of the battery pack, while less mission planning may lead to low utilization rate and limited application efficiency of the spacecraft. Therefore, the energy balance should be taken into account while planning the on-orbit tasks. The traditional spacecraft energy system formulates the task time constraint according to the maximum constraint conditions at the end of its life. There is no quantitative prediction about energy balance for specific tasks. There will be a large power surplus in the actual use of the on-orbit spacecraft, leading to the low energy utilization efficiency. To solve this problem, an energy estimation method based on task sequence and power model is proposed, which combines the orbit, power supply system mechanism, power consumption and lighting conditions during the task period, to simulate the battery state of charge throughout the task sequence. The simulation results can be applied to estimate the energy supply capacity for the planned tasks, according to which effective mission adjustment strategies can be made to effectively improve the on-orbit utilization rate of the high-power spacecraft payloads.
