2. 1. Modelling, parameter identification and aging-sensitive management of lithium-ion batteries in heavy-duty electric vehicles

   Author : Malin Andersson; Mikael Johansson; Davide Raimondo; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The battery is a component with significant impact on both the cost and environmental footprint of a full electric vehicle (EV). Consequently, there is a strong motivation to maximize its degree of utilization. Usage limits are enforced by the battery management system (BMS) to ensure safe operation and limit battery degradation. READ MORE

4. 2. Modeling and Analysis of the Interaction of Batteries and Power Electronic Converters

   Author : Rúdi Soares; Oskar Wallmark; Remus Teodorescu; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alternating current; aging; electric vehicles; harmonics; lithium-ion batteries; power converter; resonant filters; ripple; temperature control.; Electrical Engineering; Elektro- och systemteknik;

   Abstract : This thesis deals with the interaction of batteries and power electronic converters in automotive applications. Even if the additional heating caused by (unwanted) alternating currents is disregarded, there has been a concern that alternating currents can be harmful for batteries. READ MORE

5. 3. Optimization of Plug-in Hybrid Electric Vehicles

   Author : Mitra Pourabdollah; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The rising concerns about the global warming and emissions on one hand,and the limited resources of fossil fuels on the other hand, have made electrificationof vehicles a necessary topic among researchers and companies.Hybrid electric vehicles (HEV), which in addition to a primary power source,such as internal combustion engine or fuel cell, have an electric motor andan electric energy storage, such as a battery, have proved to decrease thefuel consumption.

6. 4. Electrochemical Investigation of the Reaction Mechanism in Lithium-Oxygen Batteries

   Author : Jonas Lindberg; Göran Lindbergh; Ann M. Cornell; Bryan McCloskey; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-Oxygen Batteries; Lithium Mass Transport; Oxygen Solubility; Reaction Rate Law; Reaction Mechanism; Electrode Passivation; Ultramicroelectrodes; Electrochemical Quartz Crystal Microbalance; EQCM; Chemical Engineering; Kemiteknik;

   Abstract : Lithium-oxygen batteries, also known as Lithium-air batteries, could possibly revolutionize energy storage as we know. By letting lithium react with ambient oxygen gas very large theoretical energy densities are possible. READ MORE

7. 5. On Power-system Benefits, Main-circuit Design, and Control of StatComs with Energy Storage

   Author : Hailian Xie; Hans-Peter Nee; Lennart Ängquist; Timothy Green; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy storage; Voltage source converter; VSC; Static synchronous compensation; StatCom; Active power compensation; Phase jump; Voltage dip; Weak network; Flux modulation; Deadbeat current control; Transformer saturation; Dual thyristor converter; dc interface; Electrical engineering; Elektroteknik; Electric power engineering; Elkraftteknik;

   Abstract : Static synchronous compensation (StatCom) is an application that utilizes a voltage source converter (VSC) to provide instantaneous reactive power support to the connected power system. Conventionally, StatComs are employed for reactive power support only. READ MORE
