   Sammanfattning : 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. LÄS MER

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

   Författare :Jens Groot; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER
