I used ChatGPT to research the background of KERS (Kinetic energy recovery systems) and how it functions in vehicles. With the specific keywords "Describe the functions of a KERS in cars", I got the information. Next, I used Google's search engine and gAI to give me the background info on Ampaire and their EEL aircraft. The background information was crucial for me to think about which kind of KERS is good to put in the EEL-aircraft, based on its weight, simplicity and effectiveness.  Updated on 1/11/2024 by Ashutosh Kumar

The 2017 Porsche 919 Hybrid LMP1 is powered by an advanced power unit with an internal combustion engine, a turbocharged 2.0-litre V4, and an electric system (Goodwin, 2017). The 2 engines combined produce a total output of over 900 HP. Fuel is directly injected into the ICE, which produces 500 HP. The rest comes from 2 energy recovery systems (ERS) that are stored in lithium-ion batteries (Brownell, 2017). The ERS-K (Kinetic) recovers almost 60% of the energy generated during the deceleration at the front wheel, which provides all-wheel drive functionality whenever necessary. The ERS-H (Heat) creates energy by utilising the heat from exhaust gases (Porsche AG, 2017). According to Goodwin in 2017, with the regulations set by the governing body of the Le Mans 24, the race car was allowed to consume up to 8 MJ of the energy recovered by the ERSs to cover as many laps as possible in the 24 hours of racing. This made the 919 Hybrid the most energy-efficient car on the track. With the combi
