摘要
随着共享电单车以及家用电动自行车的普及,电动自行车的续航里程问题迎来了广泛的关注。目前电动自行车的充电主要以有线充电为主,但有线充电有着许多的不便与隐患。而无线充电可以很好地解决这一问题。阐述了电动自行车的无线充电原理以及发展趋势:无线充电主要利用电磁感应技术进行电能的传输,与传统的有线充电方式相比较电动自行车的无线充电在潮湿环境下更加安全可靠,对充电来说也是更加方便快捷。介绍了无线充电技术发展的过程和所面临的问题,针对无线充电系统的电能损耗较高,提出了通过对粒子群等智能算法的优化从而实现追踪系统的工作频率并进行智能判断进行调节使无线输电系统一直工作在谐振状态,从而降低了无线充电系统在非谐振状态下的充电损耗。
With the introduction of the concept of"carbon peaks and carbon neutrality",clean energy such as wind power and solar power began to enter the public’s vision.Electric energy has become the choice of the vast majority of manufacturers and users.With the popularity of shared electric bikes and household electric bikes,the range of electric bikes has attracted wide attention.At present,electric bicycles charging is mainly based on wired charging,but wired charging has many inconveniences and hidden dangers.Wireless charging can solve this problem well,so the application of wireless charging in the field of electric bicycle has a good prospect.Wireless charging mainly uses electromagnetic induction technology to transfer electric energy.Compared with the traditional wired charging method,the wireless charging of electric bicycles is safer and more reliable in wet environment,and it is also more convenient and fast for charging.Literature[1]to Literature[5]gives a detailed introduction to the development process and problems of wireless charging technology.It is pointed out in the literature that the power loss of wireless charging system is high.Therefore,by optimizing intelligent algorithms such as particle swarm optimization,the working frequency of the system can be tracked and intelligent judgment and adjustment can be made to make the wireless transmission system always work in the resonant state,so as to reduce the charging loss of the wireless charging system in the non-resonant state.The paper mainly expounds the wireless charging principles and development trend of electric bicycles.
