Development of a Hybrid Energy Storage System using Batteries and Supercapacitors
Year: 2025
Type: article
Abstract: The development of hybrid energy storage systems (HESS), which combine batteries and supercapacitors, has accelerated due to the need for dependable and efficient energy storage. Batteries have a high energy density, but their lifespan and charge/discharge rates are limited. Supercapacitors, on the other hand, have a lower energy capacity but offer long life and quick charging. This paper presents a low-cost, practical HESS for real-time energy delivery that uses inverter output control, supercapacitor buffering, and voltage regulation based on the LM317. Improved efficiency (up to 96%), thermal stability, and voltage regulation under variable load conditions are confirmed by experimental results. Applications for the system include solar-integrated energy units, UPS systems, and EVs.
