Aircraft energy storage system

What is the energy storage system of an eVTOL aircraft?

The energy storage system of an eVTOL aircraft is a core component of its power system, directly affecting the aircraft's range, stable operation, and safety. This system mainly consists of the Battery Management System (BMS), Energy Management System (EMS), Power Conversion System (PCS), and other related electrical equipment.

Why do aircraft use electrical energy storage systems?

In today’s aircraft, electrical energy storage systems, which are used only in certain situations, have become the main source of energy in aircraft where the propulsion system is also converted into electrical energy (Emadi & Ehsani, 2000).

How to determine the size of aircraft energy storage systems?

Based on the comprehensive analysis of hydrogen economy, FC aging cost, and aircraft stability, a multi-objective parameter optimization model is established to decide the size of aircraft energy storage systems and hyper-parameters in the power controller.

Can fuel cell and battery energy storage improve aircraft performance?

Recent developments in fuel cell (FC) and battery energy storage technologies bring a promising perspective for improving the economy and endurance of electric aircraft. However, aircraft power system configuration and power distribution strategies should be reasonably designed to enable this benefit.

Why do aircraft need solar energy storage?

In solar-powered aircraft, an energy storage system is needed to meet the intense power demand during takeoff, landing, and some maneuvers and to provide energy to continue uninterrupted flight at night or in conditions of insufficient solar radiation (Gang & Kwon, 2018).

Which energy storage systems are used in solar-powered air vehicles?

In solar hybrid systems, batteries or fuel cells are usually used as auxiliary energy storage systems (Mane et al., 2016). Lithium polymer (Li-Po), lithium ion (Li-ion), and lithium-sulfur (Li-S) batteries and fuel cells are the most preferred energy storage systems in solar-powered air vehicles (Elouarouar & Medromi, 2022).
