摘要: 以电动小车无线充电为主题,实现了以超级电容为基本储能装置的电动小车动态无线充电系统。该系统使用了将无线充电模块与超级电容组相结合的模式,通过把直流电转换成高频交流电,再通过电磁感应原理为超级电容无线充电,放电时通过Boost变换为小车提供电能。实验可实现小车在跑道上的某点充电时,充电指示灯点亮起;当外界电源切断,充电断电后,小车可自动启动并循迹行驶。最终证明了超级电容与无线充电模块组合装置可实现小车在行驶中,经过通电线圈时可以进行闪充,并沿着既定运行轨道继续行进。

Abstract: This design takes the electric car wireless charging as the theme and realizes the electric car dynamic wireless charging system with the supercapacitor as the basic energy storage device.The system uses the mode of combining the wireless charging module with the ultracapacitor set.By converting the direct current into highfrequency alternating current,the ultracapacitor is charged wirelessly through the principle of electromagnetic induction.The experiment can realize the charging indicator light to light up when the car is charging at a certain point on the track.When the external power supply is cut off and the charging power is cut off,the car can start automatically and follow the track.Finally,it is proved that the combination device of ultracapacitor and wireless charging module can realize the car can flash charge when passing the electrified coil and continue to travel along the established running track.
Key words : super capacitor;boost transformation;wireless charging;automatic tracking

目前,國(guó)內(nèi)外電子設(shè)備的常規(guī)充電方式通常是通過(guò)交流電源和電子設(shè)備的二次電池充電來(lái)實(shí)現(xiàn)的。使用這種頻繁的連接和斷開(kāi)模式可能會(huì)損壞線路并導(dǎo)致觸電。而另一方面,非接觸式感應(yīng)充電器由于運(yùn)輸方便、成本低、無(wú)需布線等優(yōu)點(diǎn),在現(xiàn)階段很快引起了各界的關(guān)注。無(wú)線充電也稱為感應(yīng)充電和非接觸式感應(yīng)充電。電器組合是一種通過(guò)供電設(shè)備(充電器)將能量傳遞給需要電能的裝置。利用設(shè)備在啟動(dòng)時(shí)用接收到的能量給電池充電。充電器與電氣設(shè)備之間的電感連接是這樣的,在能量傳遞過(guò)程中,兩臺(tái)機(jī)器之間沒(méi)有電氣連接,因此不用過(guò)多地?fù)?dān)心會(huì)存在充電器和電氣設(shè)備導(dǎo)線或接點(diǎn)外露的問(wèn)題。
