Design and Experiment of Compound Vibration Energy Regeneration System for Electric Tractor
For recovering and utilizing the vibration energy generated during the driving of the electric tractor,a piezoelec-tric-mechanical-electromagnetic compound vibration energy regeneration system was proposed based on the floating battery pack.Then,based on the voltage output characteristics of the device,an electric energy extraction circuit inclu-ding the rectifier filter,LM317 voltage regulator,supercapacitor energy storage and Boost modules was constructed to meet the battery charging requirements.Finally,an actual vehicle test of the compound vibration energy regeneration system was conducted.The results showed that the maximum output voltage of the device was 34.80 V and the average output power was 0.57 W when the speed of the electric tractor was 4 km/h.After the equivalent calculation,the electric power recovered by the compound vibration energy regeneration system can extend the endurance time of the electric tractor by 0.784 7 h,which will provide theoretical and technical support for the electrical energy replenishment and the extension of working hours of China's electric tractors.
