Abstract

This paper deals with the influence of the shape of the discharge curve of Lithium Ion battery cells on the wiring harness of electrical vertical take-off and landing aircraft. A simulation framework is presented which enables a detailed simulation of the wiring harness performance over the complete mission of an aircraft. Three common reference aircraft configurations are used for the simulation to compare different harness architectures. Different possible models for predicting the voltage of single battery cells are introduced. With the selected battery model, a sensitivity study to the simulation outcome of the model coefficients is performed and discussed. The paper concludes with the general discussion about how the shape of the discharge curve of the battery influences the wiring harness performance.
