Diseño y construcción de un cargador universal de baterías con alimentación de la red eléctrica o fuente DC de 12 voltios de un automóvil

Abstract

This project presents the design and construction of a portable module of 60W that allows us to charge different types of batteries, such as lead acid batteries, nickel-cadmium, nickel-metal-hydride, Lithium-ion and Lithium-polymer. In addition, it allows load balancing to lithium batteries. Also it has a USB port for charging devices that use it. There is a brief description of the function and the model of the converters that are used to adapt the voltage and the current at the exit of it. Besides you can find the design of them. Finally, using the model of the converters we are able to design the controllers, which allow us to change the exit variables requested by the batteries. The module includes a graphic interface that allows the communication with the computer so we can check the process of charging and to obtain the data of the process.
