Hardware-in-the-Loop Modular Platform for Testing the Energy Management of Competitive & Highly-Efficient Hybrid-Electric Vehicles
Project no. PCCA191/2012, founding organism UEFISCDI
The project proposal entitled “Hardware-in-the-Loop Modular Platform for Testing the Energy Management of Competitive & Highly-Efficient Hybrid-Electric Vehicles” (HiTECH-HEV) has come to existence after several contacts with the industrial partners from Romania and based on the current trend of the research and social tendencies at international level. The hybrid vehicles can be seen on the streets these days, thus the era of using full electric automobiles is near. In this context, this project proposes the implementation and hardware in the loop testing of a high competitive hybrid-electric automobile. It is widely accepted that the main advantages of a fully electric car are: zero gas emissions, reduced noise and vibrations (increasing the comfort of the passengers). On the other hand, a fully electric automobile involves two major problems: the reduced autonomy and high cost. So, in order to be competitive with a thermal vehicle, the electric automobile should propose practically similar cost, mechanical (acceleration, maximum speed, cruise control, autonomy) and comfort performances. The 3rd task, related to the comfort issue is intrinsically respected by an electric automobile. Thus, our attention will be on the mechanical performances of the automobile, while keeping the cost within the market limits. It is true that the idea of having a similar platform, for testing electric vehicles, is not new, since other companies and research centers from Romania and abroad is spending important funds for testing the energy flow within an automobile. Two of these companies, which are interested into the construction of such a platform, have joined Technical University of Cluj-Napoca (the coordinator of this project proposal): ICPE-SA and WordPress-Romania. These two industrial actors have already a background in the field of electric/hybrid vehicles and wish to improve/develop their knowledge/products in this field. But what are the original elements of our proposal? Up to know, the scientific community has proposed motorization solutions of high power at low speeds. The common solution of electric propulsion supposes that the machine is designed for around 1,000 rpms for direct attack at the wheel (for in-wheel motors) or up to 8,000 rpm with gear. In this study we will exploit the maximum controllability of the speed, meaning that we will try to go way beyond the common speed: up to 40,000 rpm! Actually, we will try to find out the maximum controllability speed of our traction motor, knowing that, a classical motorization (with its auxiliaries) weights around 100 kg, while, for high speeds, even with a gear, the weight of the motorization could be much lighter (for permanent magnet machines).
