Asset management of electrical transportation systems using alternative charging technologies: case study Stockholm Arlanda Airport

Abstract: In order to tackle the increasing problem of emitting greenhouse gases, electricityhas been seen as one way forward. The ability to provide energy from renewablesources is something that has to be made universal in the very near future. One ofthe larger parts of the problem is the transportation industry. Big ships, trucks andairplanes travel many times around the world each day and in order to give the environmenta chance to stop deteriorating goals and frameworks have been set in placefrom different organizations and countries. One road forward is by way of electrification.An electrified transportation system can satisfy the need for heavy and fasttransportation and doing so while not spewing out emissions. A difficult section ofthe transportation industry to electrify is the aviation. Airplanes can not afford theextra weight of the enormous battery packs required to make a transatlantic flight.We must however begin somewhere. This thesis considers an electrification of theground vehicles that service the airplane while on the ground. This project is part ofa group containing five interlinked parts concerning (1) electrification of airplane, (2)LCC of electrified ground vehicle fleet, (3) how the aging of lithium ion batteries isaffected by charging strategies, (4) LCC of a lithium ion battery with regards to theaging and (5) what an electrified ground vehicle fleet means in terms of grid connectionrequirements. These five different objectives are applied on the same caseof Stockholm Arlanda Airport. The conclusions regarding the grid connection arethat an electrification of the ground vehicle fleet itself might not require an upgradeto the existing grid connection. This however depends on the charging strategyadopted and the degree to which the aviation transportation system in its entirety iselectrified.
