Working principle of the energy storage system of aircraft carrier no 003

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.

How much power does a hydrogen storage system use?

To ensure aircraft safety, the maximum power of the FC system is designed as 100 kW, the same as the aircraft's main propulsion system rated power. The energy density of a hydrogen storage system (2.3 kWh/kg) is around 20 times higher than that of the battery pack.

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.

Why do aircraft use hybrid energy storage technology?

In (a), the FC works under idle and heavy load states in 23% and 65% more time, the reason is that it should cover all the power requirements of the aircraft in the whole voyage. Compared to FC aircraft, the use of hybrid energy storage technology can significantly relieve the working pressure of FC stack.

How to optimize aircraft power system configuration & energy management strategy?

To summary, both the optimal power system configuration and energy management strategy can be derived with the developed integrated optimization method, aircraft hydrogen economy and FC anti-aging performance can be significantly improved.

How can aircraft battery size and algorithm hyper-parameters improve the economy?

With the derived optimal battery size and algorithm hyper-parameters, the economy of aircraft can be improved while the stability of the power system can be guaranteed.
