介绍了利用液压传动和电磁发电等技术研制的一种新型实用的发电系统,目的在于收集产生车辆在减速等场合产生的闲散动能;讨论了该系统的设计思路及部件选型,并对研制的系统进行了相关实验。实验结果表明:一辆小汽车通过所研制系统时,一次可以获得4.5 W左右的电能,能量收集效率约为3%。 The paper introduces a new type of practical power generation system which is developed by using hydraulic transmission and electromagnetic power generation technology. The purpose is to collect the idle kinetic energy which generated when the vehicle is decelerating and so on. The design ideas and components selection of the system are discussed. System related experiments. Experimental results show that when a car passes through the system under development, it can obtain about 4.5 W of electric energy at a time, and the energy collection efficiency is about 3%.
