RISDesign of an Improved Modular Multilevel Converter Reconfigurable Equalization Scheme Based on Difference of Voltage Variation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to solve the problem of lower available capacity and shorter cycle life due to the barrel effect of series-connected batteries, as well as the problem of pseudo-equalization caused by battery aging, this paper ...
Online Measurement of Impedance Spectroscopy of Lithium-Ion Batteries Based on Equalized Current Harmonic Injection
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Impedance spectroscopy can characterize a variety of states within a battery and shows great potential for application in safety warning and condition assessment, but there is a lack of an effective online monitoring method. ...
An Active Equalization Method for Cascade Utilization Lithium-Ion Battery Pack With Online Measurement of Electrochemical Impedance Spectroscopy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the rapid development of new energy vehicles, a large number of lithium batteries have been produced, used, and then retired. The full utilization and safe use of the whole life cycle of the batteries have become a ...
Lithium-Ion Battery State of Health Estimation Based on Electrochemical Impedance Spectroscopy and Cuckoo Search Algorithm Optimized Elman Neural Network
