Electric vehicles are, nowadays, taking more space in both the private and public transport mobility industry. They represent an old technology since their invention is dated in 1867, but over the last two decades, thanks to technological improvements, they have become an interesting and competitive alternative. The core of an electric vehicle is its battery, which is composed of a stack of cells. Each cell contributes to the overall performance of the whole system, so it is fundamental to ensure that each element works in the proper optimal conditions. One of the most important aspects, in this sense, is the thermal management of the cells: they have to work in a limited temperature window, to maximize the available power and the life of the battery pack itself.
