Reaproveitamento de células 18650 oriundas de baterias de notebook para aplicação em sistema fotovoltaico off-grid residencial: teste, estudo de caso e viabilidade econômica

Abstract

Aspects related to environmental preservation are discussed daily in different sectors of society and industry. Given the importance and limitation of natural resources, the search for alternative energy sources, such as wind and photovoltaic, becomes an emerging movement of globally known importance. Among them, photovoltaic energy plays a prominent role, due to the abundance of its source. The object of study of this dissertation is the design of a battery to power a residential off-grid system, combined with its main construction aspects. To this end, the components that characterize this system were surveyed and described, including the types of batteries normally used. From a technical and environmental point of view, the lithium-ion battery has great importance, since many electronic equipments work with devices of this nature. One of these devices is the laptop, whose battery is made up of a set of 18650 cells, which are disposed of by electronic waste companies. However, most of them offer conditions for reuse, allowing them to be applied in projects that can contribute to reducing the disposal of these objects, featuring an advantage point from the perspective of environmental preservation, combining two extremely important factors: an off-grid photovoltaic system -grid and reuse of laptop batteries.
