Currently, battery electric vehicles are the most popular EV commercially available. However, there is a growing interest for fuel cell electric vehicles (FCVs) because the latest battery technologies do not ensure a comparable range to that of conventional vehicles. Nevertheless, due to the unidirectional nature of energy transformation in a FCV, auxiliary storage systems are necessary to recover...
This paper treats the sizing and Energy Management (EM) of Fuel Cell/battery source for automotive application. The fuel cell system is used as the main source and batteries pack is the auxiliary one. A bidirectional DC/DC converter is used to connect the batteries to the DC bus and a DC/DC boost converter associates the fuel cell stack with DC link. A sizing algorithm is developed to determine the...
This research aims at developing an active energy management system for an experimental platform of the multi-energy-source electric vehicle (EV). The main purposes are to deal with the shortages of long charging time, short battery life cycles, and insufficient mileage of EVs. Hence, this research was separated into three segments: (1) active power distribution hardware, and (2) performance verification...
The credentials of fuel cell (FC) as an alternative source for electric vehicle are not encouraged by many due to its high cost and slow dynamics. Moreover, due to slow dynamics of FC dominated by temperature of fuel delivery system, fast load demand will cause a large voltage drop in a short time, which is recognized as a fuel starvation phenomenon. To overcome this problem, an energy storage system...
Fuel cell vehicle was featured with no pollution. And the energy conversion efficiency of its fuel cell was 2∼3 times higher than that of internal combustion engine. So, from the energy utilization and environment protection perspectives, fuel cell vehicle would be the ideal vehicle type in the future. The development status of fuel cell vehicles were discussed in this paper from the following aspects,...
Energy saving technologies based on the use of electricity are in many cases an alternative to thermal energy from fuels. They are lighting, electrical drives, heat pumps, microwave, induction heating, mechanical recompression of vapor, distributed control system in industry and buildings, energy storage, renewable energy sources, electric and hybrid vehicles, smart grid applications. A wider use...
