Hybrid electric vehicles and regenerative braking

Abstract

With the rapid development of the automotive industry, the fossil fuel crisis and environmental pollution issues have become increasingly severe. The demand for low energy consumption and low emissions has become an inevitable trend in automotive development. Hybrid electric vehicles effectively address the issues of driving range and emissions reduction, making them an important branch of new energy vehicle technology. Electric vehicles have long faced the challenge of limited driving range, particularly in urban driving conditions with frequent start-stop processes. This study focuses on new-energy electric vehicles and proposes an energy recovery control strategy for regenerative braking. Considering various related influencing factors, the strategy accurately allocates the regenerative braking force of the drive motor during vehicle coasting, deceleration, and braking processes. This improves the energy recovery efficiency of the vehicle while ensuring driving safety. This article introduces the operating principles and classification of hybrid electric vehicles and provides an overview of the regenerative braking technology in current hybrid electric vehicles.
