Various circuit technologies have been studied and developed. One of main streams concerns a soft switching technology to mitigate switching stress, leading to the reduction in switching losses or electro-magnetic noise. On the other hand, as a characterized orthodox technology, the existing chopper circuit is used for the electric vehicles, etc. Such technologies have a tendency to go out of v...

One promising technology to interface battery packs in electric and hybrid electric vehicles is the multilevel converter. In the work presented here, it is shown how the switching times (angles) in a multilevel inverter can be chosen to achieve a required fundamental voltage and not generate specific higher order harmonics. The method gives a complete solution to the problem in that all possibl...

In the last decade, a number of research works in electrified vehicles have been devoted to analysis electric consumption battery and evaluation main influencing factors. The literature reveals that motor size, efficiency, driving condition substantially affect energy stored vehicle battery. This paper studies degree sensitivity size its efficiency map characteristics. order accomplish this tas...

The freeFOClib (short for “free Field-Oriented Control library”) provides a framework for simulations of electric drives with different application purposes. The library can be used to simply build a field-oriented control system for existing machine models from the Modelica Standard Library, investigate the impact of electric faults (battery faults, inverter faults, machine faults) on a electr...

Lithium batteries are widely used in notebook computers, mobile phones, 3C electronic products, and electric vehicles. However, under a high charge/discharge rate, the internal temperature of lithium battery may rise sharply, thus causing safety problems. On the other hand, when the lithium battery is overcharged, the voltage and current may be affected, resulting in battery instability. This s...

Battery technology is an enabling technology for electric vehicles (EVs), and improving its safety and reliability while reducing its cost will benefit its application to EVs. In this paper, a method on the design and analysis of lithium-ion (Li-ion) battery pack from the reliability perspective is presented. The analysis is based on the degradation of the battery pack, which is related to the ...
