Abstract： In order to increase the regenerative braking energy recovery and the dynamic performance of vehicle start and acceleration in the stage of brake，the hydraulic braking energy recovery system was used with the storage battery braking energy recovery system after comparing kinds of regenerative braking recovery plan and energy storage method. The system was used to do simulation and analysis in vehicle dynamic performance and energy recovery efficiency under the PID control and ECE-15 cycle. The system simulation and analysis results show that， using hydraulic regenerative braking system in pure electric vehicle，it can significantly improve the ability of vehicle's start-acceleration and increase the vehicle driving range around 28%.
