Energy management control strategies for energy storage

4 ENERGY STORAGE DEVICES. The onboard energy storage system (ESS) is highly subject to the fuel economy and all-electric range (AER) of EVs. The energy storage devices are continuously charging and discharging based on the power demands of a vehicle and also act as catalysts to provide an energy boost. 44. Classification of ESS:

Kinetic Energy Recovery from a Landing Aircraft: Energy

kinetic energy of the aircraft is harvested and temporarily stored so that it then enables engine-less taxiing to the gate. At the gate, the energy storage device can be recharged through the grid, allowing the aircraft to perform also an engine-less taxi-out process. The main engines would only be turned on for the warm up time before take-off.
