Objectives
The goal of our research project is to instal a modular platform for testing light hybrid-electric vehicles (HEV) by using the Hardware-in-the-Loop (HiL) concept. The elements which are under study here are the propulsion and the main auxiliaries (steering, ventilation and braking systems). The hybrid character of the vehicle is at power suply level, meaning that we will test the HEV’s suply based on battery and ultracapacitor; also, the use of fuel cell suply can be taken into consideration.
The modular character of the platform is seen at all levels of the power train: the supply (we will be able to test different types of batteries, ultracapacitors, of different materials and configurations – even fuel cells could be integrated in our testing platform), the controller (which contains the control unit and the power converter – function of the electrical machine type we will have different power static converters) and the motorization (high speed and low speed structures could be integrated, as well as the with-transmission or without-transmission – in-wheel – variants; also, the magnetic or mechanical gear, with different gear ratios could be integrated).
Another degree of modularity will be applied to the auxiliaries. Based on a programmable power load we could consider a generic auxiliary consumer, which will be consider as a global consumer, or we will consider real auxiliaries, for a lower voltage level, like the auxiliaries, ventilation and braking systems, to which we could add others – like the compressor for fuel cells, micromotors for electric windows and sits etc.
In order to explain the main energy flow in our testing platform see figure below, where the motorization and the main studied auxiliaries are considered.
(A supplementary battery, of low voltage, could be used for auxiliaries, especially since their presence, when the amount of installed power is increased, could affect the vehicle’s authonomy.)
