Nws nyob deb npaum li cas ntawm lub zog hluav taws xob wireless charging thiab "them thaum taug kev"?

Musk ib zaug hais tias piv nrogsuper charging chaw nres tshebnrog 250 kilowatt thiab 350 kilowatt fais fab, wireless charging ntawm hluav taws xob tsheb yog "tsis muaj txiaj ntsig thiab tsis muaj peev xwm." Qhov cuam tshuam yog tias kev them nyiaj wireless yuav tsis raug xa mus rau lub sijhawm luv.

Tab sis tsis ntev tom qab cov lus poob, Tesla tshaj tawm qhov kev yuav ntawm Wiferion, lub tuam txhab German wireless charging, rau tus nqi siab txog US $ 76 lab, txog 540 lab yuan. Founded hauv 2016, lub tuam txhab tsom mus rau autonomous tsheb thauj mus los thiab wireless charging daws teeb meem rau kev lag luam ib puag ncig. Lub tuam txhab tau tshaj tawm tias tau siv ntau dua 8,000 lub chargers hauv kev lag luam.

Tsis xav txog, tab sis kuj xav tau.

Nyob rau hnub ua lag luam dhau los, Rebecca Tinucci, Tesla lub taub hau ntawm lub ntiaj tebthem infrastructure, tau tshaj tawm lub tswv yim ntawm cov peev txheej them nyiaj wireless rau cov tsev thiab chaw ua haujlwm. Xav txog nws thiab nkag siab tias kev them nyiaj wireless yog ib feem tseem ceeb ntawm lub zog ntxiv thiab yuav loj hlob sai lossis tom qab. Yog li ntawd, nws tsim nyog rau Tesla kom tau Wiferion thiab tau txais lub rooj zaum ua ntej. Kev txiav txim siab los ntawm pej xeem cov ntaub ntawv, Wiferion thev naus laus zis tau siv ntau dua hauv cov cuab yeej siv thiab cov neeg hlau, thiab tej zaum yuav raug teeb tsa rau Tesla cov khoom tsim tsheb lossis cov neeg hlau "Optimus Prime" yav tom ntej.

Tesla tsis yog ib leeg. Tuam Tshoj, uas tswj hwm lub ntiaj teb kev coj noj coj ua hauv kev lag luam tsheb hluav taws xob, tseem tab tom tshawb nrhiav wireless charging technology. Thaum kawg ntawm Lub Xya Hli 2023, ntawm 120-meter-ntev-ntev high-power dynamic wireless charging txoj kev hauv Changchun, Jilin, lub tsheb tsis muaj zog tshiab tau tsav tsheb zoo ntawm txoj kev tshwj xeeb hauv kev. Lub dashboard nyob rau hauv lub tsheb tso tawm "Charging". nruab nrab". Raws li kev suav, tus nqi hluav taws xob tau them los ntawm lub tsheb tshiab lub zog tom qab tsav tsheb tuaj yeem tso cai rau nws tsav tsheb mus ntxiv rau 1.3 mais. Thaum Lub Ib Hlis Ntuj xyoo tas los, Chengdu kuj tau qhib Tuam Tshoj thawj lub tsheb npav wireless charging kab.

Hauv kev lag luam hluav taws xob tshiab, Tesla muaj kev ua qauv qhia. Los ntawm kev sib xyaw tshuab tuag-casting mus rau 4680 cov roj teeb loj cylindrical, txawm tias nws yog kev siv tshuab, thev naus laus zis lossis cov khoom lag luam tshiab, txhua qhov kev txav mus los feem ntau suav tias yog tus qauv. Qhov kev xa tawm ntawm wireless charging technology rau lub tsheb hluav taws xob puas tuaj yeem pab ua kom tiav daim teb no thiab txhawb nqa wireless charging technology rau hauv cov tsev ntawm tib neeg?

Electromagnetic induction VS magnetic teb resonance, uas wireless charging technology zoo dua?

Qhov tseeb, wireless charging thev naus laus zis tsis yog tshiab, thiab tsis muaj qhov pib ua haujlwm siab.

Nyob rau hauv txoj cai, wireless charging feem ntau yog electromagnetic induction fais fab kis, sib nqus resonance fais fab kis, microwave fais fab kis, thiab hluav taws xob teb coupling wireless fais fab kis.. Cov khoom siv hauv tsheb feem ntau yog hom electromagnetic induction thiab magnetic teb resonance hom, uas tau muab faib ua ob hom: static wireless charging thiab dynamic wireless charging. Thawj yog hom electromagnetic induction, uas feem ntau suav nrog ob ntu: lub zog xa hluav taws xob thiab lub zog txais kauj. Lub qub yog ntsia rau ntawm txoj kev nto, thiab tom kawg yog kev koom ua ke ntawm lub tsheb chassis. Thaum lub tsheb hluav taws xob tsav tsheb mus rau qhov chaw, lub roj teeb tuaj yeem raug them. Txij li thaum lub zog kis tau los ntawm qhov chaw sib nqus, tsis tas yuav tsum muaj cov xov hlau txuas, yog li tsis muaj kev sib cuag nrog cov khoom siv tau.

Tam sim no, cov thev naus laus zis saum toj no tau siv dav rau kev them nyiaj wireless ntawm lub xov tooj ntawm tes, tab sis qhov tsis zoo yog qhov kev sib kis luv luv, qhov xav tau ntawm qhov chaw nruj, thiab lub zog loj poob, yog li nws yuav tsis haum rau lub tsheb yav tom ntej. Txawm hais tias qhov kev ncua deb tau nce los ntawm 1CM mus rau 10CM, lub zog xa hluav taws xob yuav poob ntawm 80% mus rau 60%, uas ua rau muaj hluav taws xob pov tseg. Lub magnetic teb resonancewireless chargingthev naus laus zis muaj cov khoom siv hluav taws xob, hluav taws xob xa hluav taws xob, lub tsheb txais vaj huam sib luag thiab tus tswj hwm. Thaum lub zog xa hluav taws xob kawg ntawm cov khoom siv hluav taws xob pom lub zog hluav taws xob ntawm lub tsheb tau txais qhov kawg nrog tib lub zog resonant, lub zog tau xa mus los ntawm huab cua los ntawm co-frequency resonance ntawm lub magnetic teb.
