Conception et réalisation d’un kit à source hybride pour la charge de batterie de laptop

Abstract

This project concerns the design and production of a hybrid source kit for laptop charging. This project aims to charge a laptop from two sources. To achieve this goal, we conducted a study of the operation of a laptop charger, noted the current, voltage, power characteristics, in order to determine the electrical power required to charge a laptop. We then carried out a brief inventory of existing sources for recharging laptops, also known as "External battery", we studied their operation and principle of recharging. At the end of this study, we determined the type of power supply to be implemented in our project, we opted for the use of an alternative source which is present in schools, homes and offices and a solar source which is free, available to everyone at any time of the day. Then we sized the power source, modeled and simulated using CAD software. Finally we realized and implemented it in a handbag to facilitate its transport. From this work a satisfactory result emerges; the hybrid source kit worked, it accomplished its primary mission, which is first of all recharging from a solar panel and a mains socket, and it recharged a laptop during the test phase. The project was not perfect, so improvements are needed in order to perfect the hybrid source kit
