Educational project
Cordless e-bike charging system

The project, carried out by the Institute of Systems and Applied Electronics in collaboration with Electronic AG, involved a Master of Science in Engineering - Electrical Engineering student as part of his thesis work.
The project led to the development of a wireless battery charging system for an e-bike, capable of transmitting power in the range of 200W-250W.
The advantage of this solution, designed for the city bicycle fleet, is that the user only needs to place his or her bicycle on top of a charging station for the charging process to begin, without any wired connection between the bicycle and the power grid.

The advantage of this solution, designed for the city bicycle fleet, is that the user only needs to place his or her bicycle on top of a charging station for the charging process to begin, without any wired connection between the bicycle and the power grid.
The student involved made both components (stationary primary and secondary on the bicycle) that make up the wireless charging system. He was in charge of both the theoretical part of the project (feasibility study) and its practical implementation (realization of a prototype meeting the requirements).
In the course of the project, he dealt in particular with:
In the course of the project, he dealt in particular with:
- magnetically coupled energy transmission system, consisting of a source (charging station) and a receiver (on board the bicycle);
- energy conversion in high-frequency resonant mode;
- optimization of conversion efficiency;
- reduction of the system's own consumption;
- development of printed circuit boards;
- construction and testing of a prototype.
