A Review of Battery Charging - Discharging Management Controller: A Proposed Conceptual Battery Storage Charging – Discharging Centralized Controller

Abstract

This paper describes the development of a centralized controller to charge or discharge the battery storages that are connected to renewable energy sources. The centralized controller is able to assist, control, and manage the battery storage charging when excessive power is available from renewable energy sources. At the same time, the centralized controller also performs battery storage discharging when the connected load requires a power source, especially when the renewable energy sources are unavailable. Background studies regarding battery storage charging-discharging are presented in the introduction section. Also, generally developed charging-discharging methods or techniques were applied at the system level and not specifically to the battery storage system level. Due to the limited study on battery storage system charging-discharging, this paper reviews some of the similar studies in order to understand the battery storage charging–discharging characteristics as well as to propose a new conceptual methodology for the proposed centralized controller. The battery storage State-of-Charge (SoC) is used as the criterion to develop the conceptual centralized controller, which is also used as a switching characteristic between charging or discharging when only the battery energy storages are supplying the output power to the connected load. Therefore, this paper mainly focuses on the conceptual methodology as well as explaining the functionality and operationality of the proposed centralized controller. A summarized comparison based on the studied charging–discharging systems with the proposed centralized controller is presented to indicate the validity of the proposed centralized controller.

Energy Consumption Analysis for the Prediction of Battery Residual Energy in Electric Vehicles

“…), vehicle (auxiliary usage), traffic (congested roads), and battery (State of Charge-SoC, capacity, etc.). The battery health and degradation form an important factor determining the energy efficiency of an EV [1][2][3][4][5][6][7][8][9]. Parts of an EV.…”

“…Authors in [4] used the vehicle dynamics equation to calculate the required mechanical energy and have also included added a temperature and time-dependent term to study auxiliaries and temperature-dependent efficiencies. The physical relations in the vehicle dynamics equation are used to construct three models for EV energy consumption prediction in [5]. In [6], multiple linear regression method is applied to a real-world trip and energy consumption data.…”
