| Abstract | ||
| Electrical power system is a main system for a Spacecraft. This system is responsible to provide the required power to all SC loads successfully until SC End-of-Life (EOL). Solar array (SA) is the primary power supply while the storage battery is the secondary one. A spacecraft Charging Analysis Tool with Battery Management Control Algorithm software program to examine spacecraft charging, has been developed. This paper has two objectives. The first objective is to develop a battery management control algorithm. The developed algorithm is to control the battery charging and discharging process during all modes of SC operation. The second objective is to develop a battery management environment to simulate the dynamic behaviour of the SC battery with the aid of the developed control algorithm to ensure the battery health. Also, the battery simulation with the developed control algorithm shall adequate the behaviour of the SC battery during the worst-case scenario and nominal operation of SC. The state of charge (SOC) of the battery, the thermal emission, voltage and pressure of the battery are calculated during worst-case scenario to prove that the battery operates well under the developed control algorithm. The dynamic behaviour of the battery together with the developed algorithms will be validated by ground tests and real telemetry. | ||
