This work analyzes the effect of the BMS on the performance of a Li-ion battery module by means of charge, discharge and frequency response tests. A model considering BMS effects is carried out and compared with a model based on a single cell approach. Experimental validation shows that single-cell based approach gives very poor results, and that overall accuracy can be significantly improved by considering...
This paper deals with the static electrical modeling of the super-gain BJT which is dedicated to an innovative 600V AC switch solution which it gives birth to. As power bipolar component, its electrical modeling is based on the Gummel-Poon model which is widely accepted and used by researchers as well as circuit simulators such as Pspice. All of the model parameters are extracted from device characterization...
This paper presents the supercapacitor characterization for hybrid vehicle applications. This characterization takes into account frequency, voltage and temperature variations. The frequencies dependence is mainly caused by the dynamics of the ions in the electrolyte. With high frequencies, the ions do not have time to reach the surfaces not easily accessible, located deeply in the pores which causes...
