Abstract
High-performance Energy Storage System Using Low-cost Sensors for a Photovoltaic and Battery Hybrid System
Highlights
There is a rapid rise in electricity price as a consequence of the upcoming global oil crisis, and the search for and the development of alterative energy sources, green energy sources, become a critical issue
Solar energy has long been seen as a promising candidate energy source to resolve the threat of oil crisis, but a disadvantage is that the generated solar power cannot be well regulated owing to a number of factors, e.g., time-varying solar radiation, climate uncertainty, and so forth
Gradually take the place of lead-acid and Ni-hydrogen batteries in the long term; LiFePO4 batteries rank first among a wide variety of Li-ion batteries owing to their high capacity and long service time.[2]. In addition, a LiFePO4 battery does not require a high current charger, indicating that it can be charged by a solar-powered battery charger even at low levels of solar radiation
Summary
There is a rapid rise in electricity price as a consequence of the upcoming global oil crisis, and the search for and the development of alterative energy sources, green energy sources, become a critical issue. Solar energy has long been seen as a promising candidate energy source to resolve the threat of oil crisis, but a disadvantage is that the generated solar power cannot be well regulated owing to a number of factors, e.g., time-varying solar radiation, climate uncertainty, and so forth. It is a significant and urgent issue to improve the performance of solar power generators in practical uses.[1]. For the performance testing of this presented two-stage battery charging strategy, high current charge/discharge characteristic curves of a LiFePO4 battery, i.e., plots of the battery voltage, current, and state of charge (SOC) against time, are obtained for the behavioral analysis of batteries
