| dc.description.abstract | Fast charging technology is crucial for improving consumer acceptance and rapid adoption of electric vehicles (EVs), but it also poses significant thermal management challenges such as reduced battery life when left uncontrolled, performance degradation, and most importantly, the possibility of thermal runaway. To address these challenges and further improve the competitive advantage of EVs against their internal combustion engine (ICE) counterparts, most EV manufacturers are equipping their vehicles with fast-charging capabilities. It is certain that temperature is a major limiting factor to the fast-charging capabilities of EVs. Therefore, this thesis addresses this challenge of fast-charging profile design by proposing an efficient electrothermal model to predict temperature rise for any fastcharging profile. The primary goal is to develop a method that generates the optimal fast-charging profile, while reducing charging time and minimising the battery temperature rise. The electrothermal model is designed using a second-order Thevenin equivalent circuit model (ECM) combined with a simplified electrical equivalent circuit thermal model, whose parameters are obtained from cell characterisation and extensive battery module testing. Using this model, a wide range of current profiles is solved, and the optimal profile is determined. Finally, selected profiles are verified through experimental testing on a battery module. Compared to the reference fast-charging profile used in the production EV, the fastest profile achieved a 3% reduction in charging time with a reduction of 0.7°C in maximum temperature. | en_US |

| dc.description.layabstract | Electric vehicles (EVs) are one of the most noteworthy ways the world is moving toward mitigating the impact of traditional internal combustion engine (ICE) vehicles on the environment. However, one major barrier to their adoption is the charging time, which is significantly longer than the time it takes to fill up a gas tank. Fast charging is one way to address this issue. However, fast charging also comes with the challenge of ensuring that the battery is still kept within safe operating temperatures. This thesis proposes a fast-charging profile for the Porsche Taycan battery module which beats its current fast-charging time designed by Porsche with a lower temperature rise. The method used to achieve this is easily replicated and could be used to design optimal fast charging profiles for other vehicles, enhancing the competitiveness of EVs and bolstering the argument for EVs over ICE vehicles. | en_US |
