Aviation plug energy storage

What is a plug-in hybrid eVTOL aircraft?

Plug-in hybrid eVTOL aircrafts adopting fuel chemical energy storage for onboard electricity production, either by ICE and generator, or FCs stack, have huge advantages in terms of the total weight of the aircraft over a mission vs. battery-only eVTOL.

How do airport-based solar PV systems provide EA charging?

The EA charging is partially supplied by an airport-based solar PV system. There are three main types of PV plants: ground-mounted on airport land, canopy-supported in airport carparks, and rooftop-mounted on airport buildings . The power output of the PV plants can be calculated by (1).

What energy sources do airports use?

The energy sources from airport to grid include PV, ESS, and the EA batteries. The electricity will be sold back to the grid when exceeding the airport demand. Plug-in and battery swap charging systems will both apply the A2G strategy.

Can airport energy system planners determine different charging infrastructure based on EA?

Two charging systems are compared for five different penetration levels of EA fleet. A2G is designed to provide demand flexibility and generate revenue for airport charging system. Conclusion is drawn for airport energy system planners to determine different charging infrastructure based on the penetration levels of EA.

How can electric vertical takeoff and landing (eVTOL) aircraft be improved?

Range and efficiency for plug-in electric vertical takeoff and landing (eVTOL) aircraft can be enhanced. This involves using fuel chemical energy storage for electricity generation onboard. This electricity generation may occur by internal combustion engines (ICEs) and generators. Alternatively, it may occur by fuel cells (FCs).

Can EA charging system reduce peak-charging power?

Researchers have studied on the novel airport energy infrastructure design for EA charging system. The most common charging strategy is the battery swap. The optimized battery swap strategy for EA charging system could reduce peak-charging power to around 50% and the electricity costs by more than 20% .
