Off‐board electric vehicle battery charger using PV array

Abstract

During the recent decade, the automobile industry is booming with the evolution of electric vehicle (EV). Battery charging system plays a major role in the development of EVs. Charging of EV battery from the grid increases its load demand. This leads to propose a photovoltaic (PV) array-based off-board EV battery charging system in this study. Irrespective of solar irradiations, the EV battery is to be charged constantly which is achieved by employing a backup battery bank in addition to the PV array. Using the sepic converter and three-phase bidirectional DC-DC converter, the proposed system is capable of charging the EV battery during both sunshine hours and non-sunshine hours. During peak sunshine hours, the backup battery gets charged along with the EV battery and during non-sunshine hours, the backup battery supports the charging of EV battery. The proposed charging system is simulated using Simulink in the MATLAB software and an experimental prototype is fabricated and tested in the laboratory and the results are furnished in this study.

Energy management strategy for photovoltaic powered hybrid energy storage systems in electric vehicles

“…where, V refers voltage across the block, 𝑁 𝑠𝑒𝑟𝑖𝑒𝑠 refers number of cells in series, branch number is referred as 𝑛 = [1,2,3]. The current via 𝑛 𝑡ℎ branch refers 𝑖 𝑛 and resistance in 𝑛 𝑡ℎ branch refers 𝑅 𝑛 .…”

“…In electric vehicle (EV), the battery has been deliberated as the most important component which has grown significantly in recent years as a result of power electronic converters [1], [2]. These difficulties present in EVs was lessened by combining high energy density sources like battery, ultra-capacitor (UC), superconducting magnetic energy storage (SMES) and flywheels storage devices [3]. The most attractive design for EVs is the battery-UC hybrid energy storage systems (battery-UC HESSs) [4].…”

A review on unidirectional converters for on-board chargers in electric vehicle

“…The aforementioned converters can be made in either unidirectional topology (G2V) or bidirectional topology (G2V and V2G) (Chaurasiya and Singh, 2019). According to the study of Nachinarkiniyan and Subramanian (2020), solar PV enabled a fast-charging station, steadily charging the battery irrespective of the radiation.…”
