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

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

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

    Author : Jens Groot; Chalmers University of Technology; []
    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
