In recent times, rapid development has been taking place in the field of batteries, which has also advanced wireless charging technology, providing battery-powered devices with greater portability and ease of use. Lithium-polymer batteries, due to their high energy density, are frequently used in mobile phones, drones, and mobile robots. The objective of the master’s thesis is to design a receiver for an inductive charging system for the wireless charging of a lithium-polymer battery in a mobile robot. In the master’s thesis, a literature review was conducted on the topic of wireless charging of lithium-polymer batteries. Appropriate electronic components were selected for the receiver of the inductive charging system intended for charging a single-cell battery. The system design and circuit planning were performed using the open-source software tool KiCad. A prototype was built, calibrated using resistive loads, and tested for efficient and safe charging. Measurements were carried out and analyzed to evaluate the influence of the mutual positioning of the coils during charging on its efficiency.
