聊聊電動(dòng)汽車無(wú)線充電
2.無(wú)線充電(Wireless Charging)
Wireless changing is different from inductive charging, and information transmission, such as radio signal。Wireless means transferring power and energy in a great distance.It is typically done through electromagnetic resonance。其實(shí)與感應(yīng)充電相比,其特點(diǎn)就是相隔的距離大了很多,采用的原理也并不相同。
無(wú)線充電的SAE標(biāo)準(zhǔn)SAE J2954TIR(technical information reference),有著眾多的參與者,很奇怪這個(gè)工作組竟然是BMW來(lái)lead的:
有個(gè)項(xiàng)目介紹挺詳細(xì)的,見參考文獻(xiàn)2,項(xiàng)目預(yù)算為$400K,我在網(wǎng)上搜到一個(gè)類似的國(guó)內(nèi)項(xiàng)目,不過(guò)我一點(diǎn)都不報(bào)希望,這位先生只會(huì)扯淡,但是預(yù)算估計(jì)相若。
其結(jié)構(gòu)為,關(guān)于天線的照片挺清晰的
