Formulation and Enhancement of an Innovative Plug-in Parallel Hybrid Power System

Abstract

This research focuses on the development of a novel plug-in parallel hybrid power system that integrates multiple power drive devices and incorporates various driving and braking modes. The system includes a power battery system, two drive motor systems, an engine, a clutch, and a transmission. The objective of this study is to enhance the power performance, efficiency, and fuel economy of the vehicle by optimizing the power drive modes and brake energy recycling. The proposed hybrid power system offers seven power driving modes and three brake energy recycling modes, enabling improved vehicle performance and energy efficiency. The engine operates solely for vehicle propulsion, eliminating energy losses during power generation. The research aims to analyze and optimize the system's performance under different operating conditions.
