متن کاملA New Cell Balancing Architecture for Li-ion Battery Packs Based on Cell Redundancy
Li-ion batteries are promoting the development of more and more performing electric vehicles (EVs) and hybrid EVs (HEVs). Thanks to their high energy density and increased current capabilities which permit to use a relative light and space saving battery packthese batteries are replacing almost all older battery chemistries in vehicle applications. Despite the advantages these cells provide, be...
متن کاملA New Optimization Algorithm for a Li-ion Battery Equivalent Electrical Circuit Identification
An equivalent electrical circuit (EEC) is commonly used to model the electrochemical aspect of a battery. Its structure can be more or less complicated depending on the needs of the application. Impedance measurements obtained by electrochemical impedance spectroscopy need non integer order impedance in order to correctly model passivation film and diffusion phenomena. Identification of the par...
متن کاملA high-gain adaptive observer for detecting Li-ion battery terminal voltage collapse
We use a high-gain adaptive observer and a trend filtering algorithm to detect early stages that lead to terminal voltage collapses in Li-ion batteries. This approach allows accurate detection without having sophisticated battery models. Theoretical analysis proves that the physical Li-ion battery becomes unstable when the estimated states of the observer enters instability. The trend filtering...
متن کاملModelling Li Ion Battery Electrode Properties
In recent years, interest in using lithium-ion (Li-ion) batteries as power sources for a wide range of devices (particularly portable devices) has grown significantly. There is thus a real need to understand at a fundamental level a wide range of battery performance criteria (energy density, power density, safety, durability, cost). Our working group considered how to model the fundamental elec...
