Electro-optical system for evaluation of dynamic inductive wireless power transfer to electric vehicles
Inductive lanes that can wirelessly transfer power to moving electric vehicles is a research theme of worldwide interest. The goal is to provide on-the-road recharg-ing, thus extending vehicle’s autonomy and reducing battery capacity require-ments. These lanes share, however, a common limitation: the power transfer is af-fected by the lateral displacement of the vehicle, with respect to the center of the lane. In the case of two-wheeled vehicles, such as electric scooters and bicycles, lateral inclination can also be pronounced enough as to interfere with power cou-pling. In order to experimentally evaluate the characteristics of such vehicular dy-namic power transfer schemes, it is then necessary to synchronously log the ve-hicle’s electric data, lateral displacement and attitude. In this paper, the design and implementation of an electro-optical measuring system with these capabilities, based on Light Detection and Ranging (LIDAR) technology and inertial sensors, is reported. A testing range with specific reference geometry, consisting of a cor-ridor of parallel walls, is used to simplify the continuous and accurate estimation of lateral displacement. The design was validated by statistical characterization of the measurement errors, using simulated trajectories. A prototype was built and mounted on a non-electric bicycle, with the first tests confirming its positioning measurement qualities. ; This research was partially supported by grant SFRH/BD/52349/2013 and project ESGRIDS – Enhancing Smart GRIDs for Sustainability, POCI-01-0145-FEDER-016434, both from FCT, the Portuguese funding agency supporting science, technology and innovation, and the MIT-Portugal Program. The authors are also thankful to R. Wiken, for his support with the mechanical implementation of the prototype at the MIT-CSAIL Machine Shop, to M. Brennan, for her generous donation of the bike used in the tests, and to L. Zvereva, who volunteered as a pilot in the first runs.
