Automobile braking energy recovery hybrid system test bench

Abstract

The invention discloses an automobile braking energy recovery hybrid system experiment bench, which comprises a control cabinet, an energy supply system, a commutator, a data acquisition system, a hydraulic braking energy recovery system and a hub motor braking energy recovery system, wherein the energy supply system is respectively connected with the hydraulic braking energy recovery system and the hub motor braking energy recovery system; and the energy supply system comprises a motor and a flywheel, the motor is connected with a spindle, one end of the spindle is connected with a first electromagnetic clutch and the other end is connected with a flywheel shaft sleeved with the flywheel, and the spindle is sleeved with a braking disc. When the energy supply system and the hydraulic braking energy recovery system are connected and braked through a second electromagnetic clutch, the flywheel drives a pump / motor to rotate, and energy is punched and stored to a hydraulic accumulator; and when the energy supply system and the hub motor braking energy recovery system are connected and braked through a third electromagnetic clutch, the flywheel drives a hub motor to rotate to generate power, and the generated power is stored to a super capacitor.

Description

technical field [0001] The invention relates to an experimental bench for an automobile braking energy recovery hybrid system. Background technique [0002] In recent years, with the rapid development of my country's economy, the national demand for automobiles has continued to increase, and the total number of automobiles in my country has continued to grow. The resulting energy crisis and environmental protection issues have also become increasingly severe. How to maximize the energy utilization efficiency of automobiles has become a direction of our current research. Studies have shown that in urban driving conditions, about 1 / 3-1 / 2 of the energy is consumed in the braking process. Take the representative Japanese 1015 cycle working condition as an example. At the end of the cycle, 50% of the driving energy of the car is consumed in the braking process. If a large amount of braking energy can be recycled, the energy utilization efficiency of the car will be greatly impr...

AI Technical Summary

Problems solved by technology

In order to study and compare the two braking energy recovery methods from multiple angles, it is necessary to build two experimental benches, which is very costly, and it is impossible to study the energy recovery status when the two braking energy is mixed, resulting in insufficient research.
