Evaluating the Potential of Multitype Energy Harvesting in New Energy Vehicles: A Systematic Review and Quantitative Analysis

Abstract

This review presents an overview in the context of the current state of the art in energy harvesting technologies for new energy vehicles (NEVs) and delves into the significant energy losses experienced by NEVs during driving, braking, and overcoming wind resistance. Based on the different forms of energy losses, the prevalent energy harvesting technologies in the NEV domain are elucidated, with a focus on the fundamental principles of vibration energy, braking energy, wind energy harvesting, and their recent advancements in practical implementations. Vibration energy harvesting involves the conversion of mechanical energy from the suspension system into electrical energy, while brake energy harvesting captures a portion of the brake friction loss as electrical energy during braking, and wind energy harvesting utilizes wind power generators on the vehicle surface to produce electricity. By quantitatively evaluating the recovery effects of different types of systems, the report demonstrates the great potential of energy harvesting technologies to improve energy efficiency and extend the range of NEVs. Furthermore, it explores the future trajectory of energy harvesting technology, envisioning its integration as a standard feature in NEVs and heralding transformative progress in the global energy and transportation sectors.
