چکیده :

In this paper, a portable renewable energy storage system has been designed and implemented. This energy storage system has 1039 watts capacity, enabling it to supply electrical energy for various electronic devices and applications, including lighting systems, laptops, and numerous other applications. The system is equipped with inputs that facilitate connection to solar energy sources, various voltage converters, or the electrical grid. Ongoing monitoring is continuously performed on critical parameters of lithium-based batteries, including over-voltage protection, over-current protection, short-circuit protection, and battery thermal management. Experimental results show that the fast charge technology in the proposed energy storage system reduces charging time by 52.38 percent compared to normal charging and by 90.90 percent compared to standard charging. Besides, the temperature of the battery pack remained within the stable and standard range during the charging operation, improving both the battery and system performance. Additionally, charge efficiency increased by 3.10 percent and 9.30 percent compared to the normal charging and standard charging methods, respectively. Furthermore, the operation of the system is also verified through the correct operation of each block and the execution of various charging operations. This indicates higher power, efficiency, speed, and precision in this field. The capability of charging through renewable energy sources continuously provides sustainable and cost-effective power.
