1. State-of-Health Estimation of Li-ion Batteries: Ageing Models
Abstract : Significant research efforts are being made to understand, and ultimately mitigate, thedegradation of Li-ion batteries upon usage. Currently, battery ageing models are used inorder to optimise the battery usage and to achieve robust battery solutions. READ MORE

2. State-of-Health Estimation of Li-ion Batteries: Cycle Life Test Methods
Abstract : Despite a rapid development, cost, performance and durability of the energy storage system are still a hindrance for a wide commercialisation of heavy-duty hybrid electric vehicles (HEV). The purpose of the work presented in this thesis is to investigate how different load cycle properties affect the cycle life and ageing processes of Li-ion cells developed for use in HEVs. READ MORE

3. Towards Low-Voltage, High-Current : A pioneering drive concept for battery electric vehicles
Abstract : The first electric low-voltage vehicles were constructed in the mid-19th century, but by the early 20th century they were progressively replacedby successors with internal combustion engines. As the consequences ofusing fossil fuels are better understood, our society is now transitioning back. READ MORE

4. Cars in Transition - An Assessment of Future Vehicle Technologies
Abstract : The transport sector is facing serious challenges in meeting long-term sustainability criteria. Radical changes in the design of vehicles to attain competitive vehicles with substantially better environmental performance will probably constitute an important part in a future sustainable transport sector.
