  2. 1. Development of a Novel Method for Lithium-Ion Battery Testing on Heavy-Duty Vehicles

    Author : Pontus Svens; Mårten Behm; Göran Lindbergh; Per Alvfors; Anders Malmqvist; KTH; []
    Keywords : Lithium-ion battery; HEV; field testing; heavy-duty vehicles;

    Abstract : Increasing demands for lower environmental impact from vehicles, including heavy-duty vehicles, have driven several vehicle manufacturers to consider adding hybrid electrical vehicles (HEV’s) to the product portfolio. Present research on batteries for HEV’s is mainly focused on lithium-ion battery chemistries, since lithium-ion batteries has the most promising technical potential compared to other types of batteries.

  5. 3. State-of-Health Estimation of Li-ion Batteries: Cycle Life Test Methods

    Author : Jens Groot; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EV; DVA; ICA; cycle life test; HEV; battery testing; State-of-health; battery model; PHEV; lithium-ion battery; impedance spectroscopy;

    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

  6. 4. State-of-Health Estimation of Li-ion Batteries: Ageing Models
