Lub ntsiab kom zoo dua ntawm lub charger nyob rau hauv lub tsheb yog hais tias nws siv off-the-shelf AC fais fab tuag, uas yuav tsum tau ntsaws rau hauv ib qho ntawm cov billions ntawm qhov hluav taws xob teeb tsa nyob rau hauv txhua lub tsev los ntawm ib tug ib tug hlau.
Theem 1 AC them nyiaj siv hluav taws xob ib zaug, 120V fais fab mov yog li 1.9KW, 220V-240V fais fab mov yog li 3.7KW.Qhov no yog txoj hauv kev tshaj plaws ntawm kev them nyiaj hauv tsev ntiag tug.
Txawm li cas los xij, cov tuam txhab feem ntau siv lub zog peb-theem rau kev them nyiaj, uas tuaj yeem ua kom muaj zog ntawm cov khoom siv hluav taws xob rau ntawm 20kW, sai dua li thawj theem ntawm kev them nyiaj.
AC charging yog txoj hauv kev yooj yim tshaj plaws los them, vim tias lub chaw them nyiaj tuaj yeem muab ntau yam kev xav tau them raws li tus neeg siv txoj kev ua neej thiab kev siv tsheb.Yog tias lub tsheb tsuas yog siv rau kev taug kev thaum nruab hnub, kev them nyiaj thaum hmo ntuj yog qhov yooj yim heev.Kev them nyiaj AC tsis zoo rau kev them nyiaj txuas ntxiv vim tias lub sijhawm them nyiaj ntev dhau lawm thiab qhov kev ncua deb yuav tsum dhau ntawm lub tsheb ntau.
Passive Cheebtsam rau lub tsheb chargers
Cov khoom siv Passive xws li cov khoom sib nqus thiab cov khoom siv hluav taws xob ua lub luag haujlwm tseem ceeb hauv txhua yam ntawm cov khoom siv hluav taws xob.Lub boost converter uas ua rau pem hauv ntej kawg ntawm PFC theem yuav muaj xws li ib hom EMC lim, lim capacitors, PFC coils, thiab ib tug DC txuas capacitor uas muab kev them nyiaj cia ntawm lub boost theem thiab on-board charger.
LLC converters tau siv dav hauv kev lag luam thiab cov neeg siv khoom siv.Txawm hais tias tsis muaj qhov tshwj xeeb tso zis choke yog siv, cov khoom sib nqus tau siv los cais cov transformers thiab tso zis EMC lim, nrog rau ntau yam capacitors.
Lub peev xwm rau kev siv lub wireless charging tau ua rau muaj kev xav tau dav dua rau cov khoom siv passive, suav nrog cov coils rau lub zog xa hluav taws xob (xa thiab txais), raws li qhia nyob rau sab xis, thiab cov khoom sib thooj kom ntseeg tau tias lub tsheb ua haujlwm zoo nrog lub charger.
Txawm hais tias muaj ntau qhov kev nce qib tsis ntev los no tau tsom mus rau cov khoom siv hluav taws xob hluav taws xob semiconductor xws li MOSFET thiab IGBT thiab lawv cov kev tswj hwm cuam tshuam, ob peb ntawm cov cuab yeej no tau paub txog lawv lub peev xwm hauv cov khoom siv tsis muaj kev txhim kho hauv lawv cov kev ua tau zoo raws li cov khoom sib txuas thiab cov cables.
Nyob rau hauv ntau daim ntawv thov, ntau yam resistors tsuas yog siv nyob rau hauv parallel los daws qhov yuav tsum tau lub zog poob.Thaum qhov no muab kev daws teeb meem ntawm theem Circuit Court, nws nce tus naj npawb ntawm cov khoom, tus nqi, thiab qhov xav tau ntawm pawg thawj coj saib - tsis muaj qhov zoo tagnrho hauv ib puag ncig hauv tsheb.Kev tsim kho tshiab tsis ntev los no yog thawj lub zog hluav taws xob muaj zog nrog AEC-Q200 kev tsim nyog (sab laug).Cov 1% kam rau ua cov cuab yeej no tau muab rau hauv cov khoom siv hluav taws xob insulated kom txuas ncaj qha mus rau lub tshuab hluav taws xob, qhov uas lawv tau ntsuas txog 800W.Lub zog hluav taws xob siab no tso cai rau ntau yam khoom siv hluav taws xob qis kom hloov tau los ntawm ib qho kev tiv thaiv ib leeg, lossis (vim nws lub peev xwm mem tes) qhov loj dua hlau-hloov resistor tuaj yeem hloov tau, txuag chaw board.
Ib qho inductor yog ib qho khoom siv uas, yog tias tsis ua tib zoo xaiv, yuav raug puas tsuaj los ntawm kev raug tshav kub thiab kev vibration ntev.Txawm li cas los xij, tus qauv rugged ua tau raws li AEC-Q200 cov qauv, xws li hlau sib xyaw fais fab choke boost thiab puck khiav thiab lim.Cov qauv tshiab kawg no muaj kev vibration siab ua haujlwm thiab muaj peev xwm ua haujlwm ntawm qhov kub txog li 150 ° C (suav nrog nws tus kheej cua sov), thaum tswj kev ruaj ntseg zoo tshaj plaws ntawm qhov ntsuas kub ntev.Lub shielding qauv zoo tshem tawm cov hlau nplaum to, yog li txo cov teeb meem electromagnetic cuam tshuam.
EVon-board charger tsum
DCNEon-board chargerFeem ntau yog siv rau hybrid tsheb, lub tsheb fais fab, tsheb npav hluav taws xob, tsheb thauj khoom hluav taws xob thiab lwm lub tsheb tshiab, thiab tsim nyog rau kev them nyiaj lithium hlau phosphate, lithium manganese acid, lead acid thiab lwm lub tsheb fais fab roj teeb.Pib koj lub chaw nres tsheb EV them cov lag luam nrogDCNE.
Rau qhov tsis muaj kev lav phib xaub nqe lus kawg ntawm on-board charger lossis kev txhawb nqa, thovtiv tauj pebthiab sau koj cov ntsiab lus, thiab peb yuav rov qab rau koj hauv 24 teev.
