Research on energy management strategy of aviation high-power battery auxiliary power supply system

Abstract

Aiming at the increasing demand for the load power of more electric aircraft, this paper proposes an energy storage system based on battery. Through the modeling of the battery and the analysis of the charging and discharging characteristics, combined with the various working conditions of the aircraft, a complete energy management strategy is designed to realize the coordinated operation of the energy storage system and the generator. Finally, a semi-physical simulation platform is built based on Plecs RT Box, and the feasibility of the proposed scheme is verified by experiments.
