Battery Simulation and Investigation Utilizing Matlab Simulink
MetadataShow full item record
As a self-sufficient power system, a satellite has to be equipped with an electrical energy storage system enabled with a rechargeable battery. To improve the quality of the energy supply at space satellite systems the new high performance battery cell technology, lithium iron phosphate (LiFePO4), is presented and investigated in this work. Evaluation factors of battery cells for an assessment of the technology are explained and the data of the lithium iron phosphate battery cell are demonstrated. Experimental tests of the cell are performed with MACCOR, a battery test system software. Additionally, a power supply system simulation of the currently used lithium ion battery in the NPSAT1 implemented in Matlab Simulink is investigated for a battery consisting of lithium iron phosphate cells.
