Multi-input portable power station design using lithium-ion battery

Abstract

A portable power station is a power station that can be easily transported to meet the electricity needs of outbound activities, night-time fishing, merchants at night markets, and refugee tents. When natural disasters such as earthquakes, landslides, tsunamis, and floods occur, the electricity network and communication networks are disrupted, despite the urgent need for electricity to supply basic things at the disaster site, such as lighting, charging cellphones, and providing other electronic equipment. This study designed and implemented a portable power station using lithium-ion batteries as a source of electrical energy, with solar modules and the State Electricity Company (PLN) power grid for recharging the batteries. The research method is experimental quantitative, and the power station is intended to generate 300 Wh of electrical energy. Tests performed include: 1) The charging process uses a 1 x 50 Wp solar module and the PLN electricity network; 2). The process of discharging involves a 50-Watt ac-led lamp and a 4.000-mAh smartphone. As a result, the portable power station can function effectively, can provide electrical energy for one 50-watt ac-led lamp for t = 6.27 hours, and can recharge a smartphone six times. While the process of recharging using a solar module took t = 8 hours, it took t = 4 hours when using the State Electricity Company (PLN) power grid.
