Thiab Lawv Yuav Tsum Tau Txais Kev Xav Tau Ib puag ncig
Kev ua lag luam rau cov hluav taws xob tsheb chargers yog qhov txaus nyiam heev rau thawj tsib mus rau xya xyoo, tom qab ntawd kev sib tw yuav sov thiab kev ua lag luam yuav paub tab. Cov uas xav kom ciaj sia yuav tsum tau sib sau ua ke los yog nrhiav ib lub niche. Ib qho ua tau yog tshwj xeeb hauv kev tsim kho tsheb lag luam. Nyob ntawd, koj yuav tsum ua kom koj lub charger plua plav-resistant thiab kub-resistant.
Wireless charging
Kev them nyiaj wireless muaj peev xwm txuas tau lub neej ntawm cov khoom siv txawb. Nws yog qhov tshwj xeeb tshaj yog rau cov tsheb uas taug kev los ntawm kev txiav txim siab ua ntej lossis nres ntawm cov ntsiab lus tshwj xeeb. Ib yam li ntawd, kev them nyiaj wireless yog tsim nyog rau kev siv hauv tsev, qhov twg lub zog qis dua. Kev them nyiaj wireless tau dhau los ua neeg nyiam hauv kev lag luam. Apple tab tom koom nrog kev them nyiaj wireless rau hauv nws cov qauv tshiab iPhone X thiab iPhone 8.
Wireless chargers kuj txo qhov xav tau rau ntau lub cables. Piv txwv li, ntsaws rau hauv lub charger cable tuaj yeem ua rau muaj cua sov ntau, uas yog nkim zog. Ib tsab ntawv ceeb toom tsis ntev los no los ntawm OneZero kwv yees tias wireless chargers tuaj yeem nkim 21 Wh ntawm lub zog.
Wireless charging transmitters yog siv los ntawm DC rail ntawm tsib mus rau 19 V, feem ntau muab los ntawm AC / DC fais fab adapter lossis USB chaw nres nkoj. Cov transmitters muaj ib tug coil thiab ib tug series capacitor. Cov coils hloov lub zog los ntawm electromagnetic induction. Qee lub wireless charging transmitters txhawb ntau lub coil arrays. Lub zog tso zis yog txiav txim siab xaiv nyob ntawm qhov sib txuas lub zog ntawm cov coils.
Wireless charging technology tau tsim rau lub tsheb, maus taus thiab lwm yam khoom siv txawb. Tam sim no, nws muaj peev xwm siv wireless charging technology hauv tsheb thiab hauv tsheb. Wireless chargers tau siv ntau hauv kev lag luam thiab kev lag luam. Piv txwv li, qee lub tsev noj mov McDonald tau teeb tsa lub chaw them nyiaj wireless.
Lub wireless charging technology yog ib qho kev daws teeb meem yooj yim rau kev them nyiaj hluav taws xob tsheb. Nws tseem tuaj yeem pab txhim kho lub tsheb fais fab. Qhov no tshem tawm qhov xav tau ntawm lub zog loj khaws cia thiab ua rau lub tsheb hluav taws xob sib zog thiab ntau dua.
Sic MOSFETs
Onboard chargers yuav tsum dissipate ntau pua watts ntawm lub hwj chim nyob rau hauv ib tug compact vaj tse. Qhov no feem ntau yuav tsum tau heatsinking lossis kua txias. Ib qho kev xav tseem ceeb ntawm kev tsim qauv yog yuav ua li cas koom ua ke cov keyboards nrog cov txheej txheem heatsinking. SiC FETs nrog TO-247-4L pob khoom zoo haum rau cov khoom siv hauv lub nkoj. Siv wafer-thinning thev naus laus zis, nyiaj-sinter tuag, thiab cov khoom siv hluav taws xob cais tawm, UnitedSiC's SiC FETs muaj kev ua haujlwm zoo heev.
Silicon carbide thev naus laus zis tuaj yeem hloov kho rau ntau qhov chaw xav tau. Onboard chargers yog ib qho piv txwv zoo, thiab cov khoom siv silicon carbide tau siv rau hauv kev siv tsheb ntau tshaj kaum xyoo. Raws li cov roj teeb tsheb tsheb tau nrov dua, qhov kev thov rau SiC MOSFETs yuav nce ntxiv.
Hauv tsheb fais fab, SiC MOSFETs tuaj yeem hloov IGBTs, muab qhov ntsuas hluav taws xob siab. Cov thev naus laus zis tshiab no tseem muaj ob txoj kev siv hluav taws xob ntws, ua rau nws muaj txiaj ntsig zoo rau cov khoom siv hluav taws xob thiab tsheb-rau-txhua yam kev siv. Tsis tas li ntawd, cov khoom siv silicon carbide tuaj yeem pab cov neeg tsim qauv txhim kho lub zog tsim qauv thiab txo qhov loj thiab qhov hnyav ntawm lawv cov khoom.
Nyob rau hauv bidirectional onboard charger, ob 60 mO MOSFET yog siv nyob rau hauv txhua txoj hauj lwm, thiab ib tug 25 mO MOSFET yog siv nyob rau hauv DCDC txoj hauj lwm. Lub bidirectional onboard charger siv tus qauv tsim los ntawm Wolfspeed siv Wolfspeed SiC MOSFET thiab Wolfspeed lub zog-tsim tshuab los daws cov teeb meem tsim hluav taws xob. Qhov tshwm sim yog qhov qis dua cov suav thiab qhov loj me, thiab nce qhov system zog ceev.
Kev lag luam automotive kev lag luam rau SiC fais fab kev daws teeb meem yog kwv yees kom tshaj $ 1 nphom los ntawm 2025. Nws xav tias yuav loj hlob ntawm qhov nruab nrab ntawm 38 feem pua ntawm ib xyoos. Qhov kev thov yog tsav los ntawm SiC-raws li onboard chargers, DC-DC converters, thiab traction inverters. Tsis ntev los no, UnitedSiC tau tshaj tawm tshiab 750V tiam 4 (G4) SiC FET thev naus laus zis, uas muaj peev xwm xa cov khoom siv hluav taws xob zoo dua qub, txo qis hluav taws xob, thiab txhim kho cov nqi ntsuas kev ua tau zoo.
Diodes
Hluav taws xob tsheb chargers yuav yog lub neej yav tom ntej ntawm kev thauj mus los thiab yuav tsum muaj peev xwm ua tau raws li qhov xav tau ntawm cov neeg siv khoom hauv ntau qhov chaw sib txawv. Kev sib tw rau cov tuam ntxhab thiab cov muag khoom yog nrhiav txoj hauv kev los nqis peev hauv kev lag luam loj hlob no thiab xyuas kom lawv muaj peev xwm nyob twj ywm. Qhov no yog qhov yuav tsum tau ua kom zoo thiab ceev tuaj.
Cov thev naus laus zis tau ua rau nws muaj peev xwm los tsim kev daws teeb meem ntawm cov hluav taws xob tsis sib xws. Lub tshuab no kuj yog ib qho kev daws teeb meem zoo rau cov zej zog uas xav tsim cov khoom siv hluav taws xob txuas ntxiv mus. Nyob rau hauv txoj kev no, cov peev txheej hluav taws xob ntawm lub zej zog muaj peev xwm tuaj yeem faib tau.
Kev ua lag luam onboard charger xav tias yuav loj hlob ntawm qhov nrawm nrawm hauv xyoo tom ntej. Kev lag luam loj hlob rau EVs yog tsav kev loj hlob hauv kev lag luam. Tsis tas li ntawd, kev txhim kho hauv kev them nyiaj yog ua kom lub zog ceev thiab txuag hluav taws xob. Raws li qhov tshwm sim, lub lag luam thoob ntiaj teb onboard charger xav kom ncav cuag US $ 6.5 nphom los ntawm 2030. Qhov no txhais tau tias kev ua lag luam yuav loj hlob ntawm 16 feem pua CAGR ntawm 2021 thiab 2030.
Lub neej yav tom ntej ntawm kev them nyiaj infrastructure nyob ntawm kev hloov pauv ntawm tsoomfwv txoj cai thiab cov qauv. Cov tsheb hluav taws xob yuav dhau los ua ntau dua hauv peb lub neej, thiab qhov no txhais tau tias peb yuav tsum tau hloov kho cov kev them nqi hluav taws xob kom tau raws li lawv cov kev xav tau. Tus yuam sij rau kev vam meej hauv qhov no yog xav txog cov kev xav tau ntawm cov neeg muaj feem cuam tshuam thiab tsim cov thev naus laus zis thev naus laus zis.
Onboard chargers yuav tsum muaj peev xwm daws tau qhov kev xav tau ntawm lub tsheb fais fab thiab cov teeb meem uas lawv ntsib. Kev tshawb fawb tam sim no tsom rau kev txo qis lawv qhov loj thiab qhov hnyav thaum tuav lub zog siab ceev. Lawv kuj yuav tsum muaj peev xwm tiv taus qhov kub thiab txias, kev co, thiab hluav taws xob nrov.
Sensor hlau
Sensor xov hlau rau onboard chargers yog cov khoom tseem ceeb ntawm onboard charging chaw nres tsheb. Cov chaw them nqi no feem ntau yog nruab nrog kev sib txuas thiab kev ntsuas tam sim no los saib xyuas cov hluav taws xob siv. Cov xov hlau muab cov lus qhia tawm tswv yim thiab feem ntau tau teev tseg los ntawm SAE J1772 lossis IEC 62196 schemes. Cov xaim hluav taws xob feem ntau yog yooj yim rau kev tsim thiab siv tsawg dua li cov khoom siv ntsaws ntsaws. Lawv kuj xav tau kev saib xyuas tsawg dua thiab feem ntau pheej yig dua los tsim.
Greenfield qhov chaw
Yog tias koj tab tom nrhiav los tsim lub chaw them nyiaj tshiab rau koj lub tsheb hluav taws xob, lub nroog Greenfield tau ua rau nws ua tau nrog kev pab los ntawm Western Massachusetts Electric Company. Qhov chaw nres tsheb them nyiaj no nyob ze ntawm GCC sab qaum teb kawg thawj pem teb nkag thiab koj tuaj yeem nkag mus rau nws siv tus lej nkag uas tau muab.
