  1. 1. State Estimation of Lithium-ion Batteries

    Author : Xiaolei Bian; Longcheng Liu; Jinying Yan; Huazhen Fang; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Lithium-ion battery; State of charge; State of health; Model-based method; Extended Kalman filter; Filter tuning; Fusion model; Chemical Engineering; Kemiteknik;

    Abstract : To guarantee the safety operation, the key states of lithium-ion battery, e.g., the state of charge and the state of health, must be estimated and monitored accurately. This thesis is mainly to develop models and algorithms to accurately and robustly estimate the key battery states, based on the available measurements i. READ MORE

  2. 2. Structural Composite Lithium-Ion Battery : Effect of Intercalation induced volumetric changes on micro-damage

    Author : Johanna Xu; Janis Varna; Andrejs Pupurs; Göran Lindbergh; Kenneth Runesson; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera kompositmaterial;

    Abstract : The quest for lighter materials and structures to reduce climate impacts in the automotive industry has paved the way for multifunctional solutions. Mass saving on a system level can be achieved by materials or structures having more than one primary function, thus reducing the number of components used. READ MORE

  3. 3. Lithium-ion batteries for off-grid PV-systems
