Description:ENERGY STORAGE SYSTEM

Field of Invention
The present invention relates to the energy storage system. More particularly, an Energy Storage System (ESS) that utilizes advanced battery management and control techniques to optimize the performance of energy storage devices to maximize the efficiency of energy storage and release.

Background of the Invention
The Energy Storage System (ESS) captures energy from various sources and stores it for later use. ESSs can store energy in many forms, including chemical, mechanical, electrical, and thermal. They can help improve the reliability and stability of electrical grids by balancing energy supply and demand. In the field of energy storage systems (ESS), several studies have been conducted that focus on maximizing the efficiency of energy storage and release using advanced battery management and control techniques.
M. Zhang, Y. Wang, and H. Li, "Advanced Battery Management System for Optimizing Energy Storage Efficiency in Electric Vehicles," IEEE Transactions on Industrial Electronics, vol. 66, no. 11, pp. 8841-8850, 2019.
Technical Drawback: While this study presents an advanced battery management system for EVs, it primarily focuses on optimizing the battery's charge/discharge cycles without adequately addressing the integration of multiple energy storage devices (e.g., supercapacitors) for enhanced overall system performance. The lack of a comprehensive strategy for combining different storage technologies can limit the system's efficiency and reliability, especially in applications that require rapid energy release or absorption.
To address the prior art in relation to the proposed Energy Storage System (ESS), we can reference the following patents and published applications, along with their associated technical drawbacks:
US Patent No. 8,030,896 - "Battery management system and method for an energy storage device" Technical Drawback: This patent describes a battery management system that focuses on balancing the charge among cells in a battery pack. However, the system lacks the ability to optimize energy storage and release based on real-time energy demands and varying energy sources. The absence of advanced control algorithms limits its efficiency, particularly in scenarios where energy needs fluctuate dynamically, leading to potential energy waste.
US Patent No. 7,633,153 - "Method and system for managing the power of a hybrid energy storage system" Technical Drawback: This patent involves a hybrid energy storage system combining different types of energy storage devices, such as batteries and supercapacitors. While it addresses some aspects of energy management, it does not incorporate real-time monitoring or advanced control techniques to adaptively manage energy storage and release. The system's static control approach can result in suboptimal energy usage, especially when dealing with variable energy sources, leading to inefficiencies in energy management. Problem in Prior Art: The common problem across these prior arts is the absence of advanced, real-time control algorithms and dynamic monitoring capabilities that can adapt to varying energy demands and sources. This limitation results in inefficiencies in energy storage and release, potentially leading to energy waste and reduced overall reliability of the energy storage system.
The present invention addresses and overcomes the drawbacks and deficiencies of available energy storage solutions by implementing a multifaceted approach that enhances both the efficiency and reliability of energy storage and release.
