1. 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

2. Assessment of safety characteristics for Li-ion battery cells by abuse testing
Abstract : Despite the many advantages with lithium-ion batteries there can be disadvantages in form of safetyissues. In an abuse situation a Li-ion cell can undergo a thermal runaway releasing excessive heat,flammable and toxic gas emissions and eventually accompanied by dissembling/explosion and fire. READ MORE

3. Battery thermal management for electric vehicles operating in cold climates
Abstract : Electromobility has gained significance over recent years in an attempt to reduce greenhouse gas emissions which contribute to climate change. The requirements on the performance and efficiency of electric vehicles are high to make them an attractive alternative to the conventional fossil-fuel driven vehicles. READ MORE

5. Towards sustainable urban transportation : Test, demonstration and development of fuel cell and hybrid-electric buses
Abstract : Several aspects make today’s transport system non-sustainable: • Production, transport and combustion of fossil fuels lead to global and local environmental problems. • Oil dependency in the transport sector may lead to economical and political instability. READ MORE
