Research on Hydraulic Regenerative Braking System for Pure Electric Vehicle Based on AMESim

摘要

In order to increase the regenerative braking energy recovery and the dynamic performance of vehicle, the hydraulic braking energy recovery system is confirmed to use with the storage battery braking energy recovery system after comparing kinds of regenerative braking recovery plan and energy storage methods. Through PID control, simulation under ECE-15 cycle working mode and analysis of vehicle dynamic performance and energy recovery efficiency are conducted. The system simulation and analysis results show that using hydraulic regenerative braking system in pure electric vehicle can significantly improve the ability of vehicle's start-acceleration and the increase in vehicle driving range reaches around 28%.
