Charging Forward on Petroleum Alternatives

2011-12-14
The pace of replacement of petroleum-based fuels as the primary fuel supply for transportation may still be a point of debate. However, the need to find a viable replacement fuel or group of fuels is no longer a major point of debate. The panel will outline what has changed on the journey during the past few years and what the future holds. Viewpoints from government, the military, fuel suppliers and academia will be presented.

Spotlight on Design: Fuel Efficiency: Racing Toward CAFE 2025

2015-04-15
“Spotlight on Design” features video interviews and case study segments, focusing on the latest technology breakthroughs. Viewers are virtually taken to labs and research centers to learn how design engineers are enhancing product performance/reliability, reducing cost, improving quality, safety or environmental impact, and achieving regulatory compliance. Fuel efficiency, or simply put, how to get more mileage out of the same amount of fuel has become one of the main goals to be achieved by new automotive technologies in the future, thanks in part to new government regulations. In the episode “Fuel Efficiency: Racing toward CAFE 2025” (21:24) AVL engineers show simulation and testing being used to design more fuel efficient vehicles, including the equipment that actually analyzes fuel economy.

With the continuous development of the electrical vehicles (EVs), the electric power network and transportation network are interconnected by EVs which require a coordinated operation of the two networks. In view of these coupled networks, this paper proposes a charging navigation strategy for EVs based on charging power adjustment, which can not only provide the navigation path with the shortest total operational time for EVs from the origin node to the completion of charging, but also effectively reduce load fluctuations in the electric power system. In the electric power system, an innovative optimization strategy for adjusting the EV charging power distribution is proposed, which can adjust the charging power in a timely and effective manner according to the response of EV charging. The multi-objective particle swarm optimization (MOPSO) algorithm and the improved Dijkstra algorithm are used for solving the obtained the EV charging power adjustment plan and charging paths.

Pure electric vehicles are recognized as one of the most important new energy vehicle types to meet the increasingly stringent standards in energy saving and environment protection. To meet the control demands, China Automotive Technology & Research Center(CATARC) plan to develop an advanced Vehicle Control Platform(VCP) for pure electric vehicles. The developed VCP is well structured on both hardware and software and can be adapted to different pure electric vehicles easily. This paper describes the design of the hardware, the software architecture, the base software and the control strategy applied in the VCP in detail. A matching method is proposed to configure the VCP to a real VCU for the specific application by modifying the hardware channel definition and the control parameters. The paper shows successful application of the VCP on several types of pure electric vehicles.
