Development of a 3kWh Battery-Supercapacitor Hybrid Energy Storage System

As the concern of climate change and environmental issues escalates, the demand for renewable and sustainable energy increases. The energy generation through wind turbines, Solar panel, and other methods of energy generation requires a reliable energy storage system to efficiently store the surplus energy for usage where energy generation would otherwise be unavailable. This paper introduces the development of a 3kWh Battery-super-capacitor Hybrid Energy Storage system, the outcome, and potential improvements for future development. It is built using lithium-iron-phosphate (LFP) batteries with prismatic lithium-ion capacitors (LIC). Additionally, the built-in battery management system (BMS) allows data visualization and provides the necessary protection for the system.
