The modeling and design of an active battery cell balancing system using MultiLevel Converter (MLC) for EV/HEV/PHEV is studied. The MLC allows to independently switch ON/OFF each battery cell in a battery pack . This extra degree-of-freedom (DoF) can be exploited to optimally use each cell in order to balance among them the temperature and state-of-charge (SoC). This study has shown that the co...

This paper presents a design method of a torque control strategy for parallel hybrid electric vehicles (PHEV) by using fuzzy logic. Taking the driver command, the state of charge (SOC) of the battery, and the motor/generator speed as inputs, a fuzzy controller and relevant fuzzy rules have been developed to effectively determine the torque distribution between electric motor (EM) and internal c...

The continued increase of gas prices and concerns on greenhouse gas emissions in recent years have led to the steadily increasing acceptance of electric vehicles (EVs), especially the plug-in hybrid electric vehicles (PHEVs), by consumers. It seems that PHEVs are poised to become a serious contender for a noticeable share of the car market in the near future. As PHEV draws power through power e...

Plug-in Hybrid Electric Vehicles (PHEVs) are the vehicles that depend on energy from power grid. When such vehicles are deployed in large scale, there will be great demand for energy in peakhours. There will be different levels of usage based on time. Towards this end, optimizing the supplydemand and also pricing for PHEVs is very challenging problem to be addressed. Recently there was a soluti...
