Household use of autonomous power sources in conditions of limited resources: blackout experience

During power outages, the use of universal mobile batteries, also known as power banks, has become extremely relevant. The prices of such devices have increased dramatically, and there have also been problems with the supply of these devices. Questions remain open regarding the correspondence of the declared characteristics with the real possibilities of universal mobile batteries, since some suppliers install demolished power cells, which make it possible to reduce the price of the battery for the final purchase. The article provides information on the possibilities of reusing power elements from laptop batteries in conditions of limited resources. The processes of creating universal mobile batteries for powering mobile phones, laptops, network equipment (ONU terminal and router), just like providing emergency lighting are considered. The object of research is lithium-ion batteries. The subject of research is the processes of reusing batteries in everyday life. The operation method is to increase the duration of operation and increase the efficiency of the use of laptop batteries. The author concludes that the proposed implementation is more energy-efficient due to a larger number of current converters. The reproducibility of the proposed implementations is also noted.
