The frame of this project is the design and assembling of a competition electric motorcycle by the MotoSpirit Team. MotoSpirit is competing in MotoStudent, a university competition at worldwide level in which engineering student test their skills and knowledge gained during their studies. The electric automobile industry is in clear uprising nowadays, with more regulations in terms of emissions for the vehicle sector, the society gaining knowledge on the global and local environmental challenges that it faces and the emergence of new technologies that point to a more sustainable future, with the electric vehicle being the clearest and closest example to the citizen. MotoSpirit’s vision is aligned with this change. The team takes part in MotoStudent in its electric category betting for the new and sustainable technologies. As Steve Jobs once said "The only way for people to do great at work, is to get them to do work they love" and, if on top of that this work helps in making the world a little more sustainable than the day before, this is the purpose of any human being achieved. The batteries are the heart of electric vehicles, as a motor assembled in a car is useless without them. Batteries are able to store energy to then power vehicles with no emissions. Nevertheless, the battery is a complicated system containing chemicals and hazardous substances. This is why the management of the batteries is of main importance. The industry not only has to produce batteries to store the energy produced with renewable sources, but the batteries have to be studied and perfected so they can have a longer life cycle, and once they are dead, reuse them and recycle all of their parts to create second generation batteries minimizg waste. The thermal management of a battery plays a very important role in this aspect, as its role is to keep the battery working under the safety constraints and the best thermal conditions possible for obtaining better performance and longevity. The principal goal of this thesis is to study the thermodynamics of the electric motorcycle designed by MotoSpirit under different conditions and find out which and where are the points that can originate problems in the behaviour and life of the battery, being similar to an report of the thermal ability or capacity of the battery and where should it be improved. For this, the thesis starts with the collection of the theoretical principles behind the battery system and the examples of how the problem of thermal management of a battery is handled nowadays by the battery and electric vehicle manufacturers. Following is the presentation and more importantly the thermodynamics study of MotoSpirit’s battery pack, where the simulations made are explained. The discussion of the result points out the information collected during the sim- ulations and the results obtained. Finally, the conclusions list the most important aspects found, problems and ideas of the solutions to be adopted by MotoSpirit’s team in its final battery design.
