Tshiab wireless charging technology los ntawm Chalmers University tuaj yeem muab tau txog 500kW ntawm lub zog nrog tsawg dua 2% poob.
Cov kws tshawb fawb ntawm Chalmers University hauv Sweden hais tias lawv tau tsim lub tshuab them nyiaj wireless uas tuaj yeem them cov roj teeb txog li 500 kilowatts yam tsis tau txuas rau lub charger nrog cables.Lawv hais tias cov khoom siv them nyiaj tshiab tau ua tiav thiab npaj rau kev tsim tawm series.Cov thev naus laus zis no yuav tsis tas yuav raug siv los them tus kheej cov tsheb thauj neeg, tab sis nws tuaj yeem siv rau hauv hluav taws xob ferries, tsheb npav, lossis tsheb tsis muaj neeg siv hauv kev tsuas lossis kev ua liaj ua teb kom them nyiaj yam tsis siv lub caj npab lossis txuas rau lub zog.
Yujing Liu, xibfwb ntawm Hluav Taws Xob Engineering hauv Lub Tsev Haujlwm Saib Xyuas Hluav Taws Xob ntawm Chalmers University, tsom mus rau kev hloov pauv hluav taws xob txuas ntxiv thiab kev siv hluav taws xob ntawm kev thauj mus los."Lub marina tuaj yeem muaj lub kaw lus tsim los them tus ferry ntawm qee qhov chaw nres tsheb thaum cov neeg caij tsheb nce thiab tawm ntawm lub nkoj.Tsis siv neeg thiab tsis muaj kev ywj pheej ntawm huab cua thiab cua, lub kaw lus tuaj yeem them 30 mus rau 40 zaug hauv ib hnub.Cov tsheb thauj khoom hluav taws xob yuav tsum tau them lub zog siab.charging cables tuaj yeem ua tuab thiab hnyav thiab nyuaj rau kev ua haujlwm. "
Liu tau hais tias kev txhim kho sai ntawm qee yam khoom siv thiab cov khoom siv hauv xyoo tas los no tau qhib qhov rooj rau qhov muaj peev xwm them nyiaj tshiab."Qhov tseem ceeb tshaj plaws yog tias tam sim no peb tau nkag mus rau lub zog loj silicon carbide semiconductors, hu ua SiC Cheebtsam.Hais txog hluav taws xob hluav taws xob, lawv tsuas yog nyob rau hauv kev ua lag luam rau ob peb xyoos.Lawv tso cai rau peb siv ntau dua qhov hluav taws xob, qhov kub thiab txias ntau dua, "nws hais.Qhov no yog ib qho tseem ceeb vim hais tias qhov zaus ntawm lub magnetic teb txwv lub zog uas yuav kis tau ntawm ob coils ntawm ib tug muab me me.
"Thaum dhau los wireless charging tshuab rau tsheb siv zaus nyob ib ncig ntawm 20kHz, ib yam li cov pa ncu.Lawv tau dhau los ua qhov loj thiab lub zog hloov pauv tsis muaj txiaj ntsig.Tam sim no peb tab tom ua haujlwm ntawm zaus plaub zaug siab dua.Tom qab ntawd induction mam li nco dheev ua txaus nyiam, "piav qhia Liu.Nws hais ntxiv tias nws pab neeg tshawb fawb tswj hwm kev sib raug zoo nrog ob lub ntiaj teb ua lag luam ntawm SiC modules, ib qho hauv Asmeskas thiab ib qho hauv lub teb chaws Yelemees.
"Nrog lawv, kev txhim kho sai ntawm cov khoom lag luam yuav raug coj mus rau ntau dua tam sim no, voltages thiab cov teebmeem.Txhua ob lossis peb xyoos, cov ntawv tshiab yuav raug nthuav tawm uas ua rau siab ntev dua.Cov khoom siv no yog qhov tseem ceeb, muaj ntau yam kev siv hauv tsheb hluav taws xob, tsis yog kev them nyiaj inductive xwb. "".
Lwm qhov kev siv thev naus laus zis tsis ntev los no suav nrog cov xov tooj tooj liab hauv cov coils uas feem xa thiab tau txais qhov oscillating magnetic teb uas tsim ib tus choj virtual rau qhov ntws ntawm lub zog hla qhov sib txawv ntawm huab cua.Lub hom phiaj ntawm no yog siv cov zaus ntau tshaj plaws.“Tom qab ntawd nws tsis ua haujlwm nrog cov coils ncig los ntawm cov hlau tsis tu ncua.Qhov no ua rau poob loj heev ntawm cov zaus siab, "Liu hais.
Hloov chaw, cov coils tam sim no suav nrog braided "txoj hlua tooj liab" ua los ntawm 10,000 tooj liab fibers tsuas yog 70 mus rau 100 microns tuab - txog qhov loj ntawm ib txoj hlua ntawm tib neeg cov plaub hau.Xws li hu ua litz hlau braids, haum rau cov dej ntws siab thiab siab zaus, kuj tau tshwm sim tsis ntev los no.Ib qho piv txwv thib peb ntawm cov thev naus laus zis tshiab uas ua rau muaj zog wireless charging yog hom tshiab capacitor uas ua rau kom lub zog reactive xav tau los ntawm kauj los tsim kom muaj zog txaus sib nqus.
Liu tau hais tias kev them nyiaj hluav taws xob tsheb yuav tsum muaj ntau yam kev hloov pauv ntawm DC thiab AC, nrog rau qhov sib txawv ntawm qhov sib txawv."Yog li thaum peb hais tias peb tau ua tiav 98 feem pua ntawm qhov ua tau zoo ntawm DC ntawm qhov chaw them nyiaj rau lub roj teeb, tus lej ntawd yuav tsis muaj teeb meem ntau tshwj tsis yog koj paub meej txog qhov koj ntsuas.Tab sis koj hais tau tib yam., Txawm hais tias koj siv Losses tshwm sim nrog cov pa hluav taws xob them lossis nrog kev them nyiaj inductive.Qhov kev ua tau zoo uas peb tau ua tiav tam sim no txhais tau hais tias qhov kev poob hauv inductive charging tuaj yeem yuav luag qis li hauv cov khoom siv hluav taws xob.Qhov sib txawv me me heev uas nyob rau hauv kev xyaum nws yog negligible, txog ib los yog ob feem pua. "
Cov neeg nyeem CleanTechnica nyiam specs, yog li ntawm no yog qhov peb paub los ntawm Electrive.Chalmers cov kws tshawb fawb tau lees tias nws qhov kev them nyiaj wireless yog 98 feem pua ntau thiab muaj peev xwm xa mus txog 500kW ntawm qhov ncaj qha tam sim no ib ob square metres nrog 15cm huab cua sib txawv ntawm av thiab onboard pads.Qhov no sib raug rau qhov poob ntawm tsuas yog 10 kW lossis 2% ntawm qhov theoretical siab tshaj them lub zog.
Liu zoo siab txog qhov tshiab wireless charging technology.Piv txwv li, nws tsis xav tias nws yuav hloov txoj kev uas peb them hluav taws xob tsheb."Kuv tsav tsheb hluav taws xob rau kuv tus kheej, thiab kuv tsis xav tias kev them nyiaj inductive yuav ua rau muaj qhov txawv txav yav tom ntej.Kuv tsav tsev, ntsaws rau hauv… tsis muaj teeb meem. ”ntawm kab.“Tej zaum nws yuav tsum tsis txhob sib cav tias thev naus laus zis nws tus kheej muaj kev ruaj ntseg dua.Tab sis nws tuaj yeem ua rau nws yooj yim dua rau hluav taws xob tsheb loj, uas tuaj yeem ua kom nrawm rau theem-tawm ntawm cov khoom xws li diesel-powered ferries, "nws hais.
Them lub tsheb txawv heev ntawm kev them lub ferry, dav hlau, tsheb ciav hlau, lossis roj rig.Feem ntau cov tsheb nres 95% ntawm lub sijhawm.Cov cuab yeej ua lag luam feem ntau yog nyob rau hauv qhov kev pabcuam tas li thiab tsis tuaj yeem tos kom them rov qab.Liu pom cov txiaj ntsig ntawm cov thev naus laus zis tshiab inductive rau cov xwm txheej lag luam no.Tsis muaj leej twg yuav tsum tau them 500 kW hluav taws xob tsheb hauv chaw nres tsheb.
Lub hom phiaj ntawm txoj kev tshawb no tsis yog nyob rau hauv wireless charging per se, tab sis yuav ua li cas cov thev naus laus zis txuas ntxiv qhia cov tshiab, pheej yig dua, thiab muaj txiaj ntsig ntau dua ntawm kev ua tej yam uas tuaj yeem ua kom lub zog hluav taws xob hloov pauv.Xav txog nws zoo li lub hnub qub ntawm PC, thaum lub tshuab tshiab thiab zoo tshaj plaws tau dhau los ua ntej koj txawm mus tsev los ntawm Circuit City.(Nco ntsoov lawv?) Niaj hnub no, cov tsheb hluav taws xob tau ntsib qhov zoo sib xws ntawm kev muaj tswv yim.Zoo nkauj kawg li os!
Steve sau txog kev sib raug zoo ntawm thev naus laus zis thiab kev ruaj ntseg los ntawm nws lub tsev hauv Florida lossis nyob qhov twg lub Force coj nws.Nws txaus siab rau nws tus kheej ntawm "sawv" thiab tsis quav ntsej vim li cas lub khob tawg.Nws ntseeg qhov uas Socrates tau hais 3,000 xyoo dhau los: "Qhov zais cia ntawm kev hloov pauv yog tsom tag nrho koj lub zog ntawm kev tsim cov tshiab, tsis yog tawm tsam cov qub."
