Abstract
With the rapid advancement of technology, we are moving towards a society that is increasingly driven by computer intelligence. At the same time, we are facing pressing environmental issues that are pushing us towards cleaner solutions. One industry that is heavily influenced by these two factors is the automotive industry, where autonomous electric vehicles are gaining more popularity. Audi AG, one of the biggest car manufacturer companies, is now trying to take a step forward in this market by implementing two low-voltage energy sources into the system to improve automation features. The main obstacle to the introduction of these energy sources is the strong influence that temperature has on them. Both high and low temperatures are detrimental to the battery's lifespan and performance and, in extreme conditions, they may completely impede the energy source from supplying energy or lead to thermal runaway. Therefore, effective thermal regulation of the energy source is fundamental to ensure battery availability and enhance efficiency. The objective of this research is to develop a new thermal regulating system for low-voltage energy sources in autonomous electric vehicles.
