Kev loj hlob ntawm kev lag luam tsheb hluav taws xob yuav xav tias yuav tsis muaj: kev tsom mus rau txo CO2 emissions, kev nyab xeeb kev nom kev tswv tam sim no, kev nqis peev los ntawm tsoomfwv thiab kev lag luam tsheb, thiab kev nrhiav tsis tu ncua ntawm txhua lub zej zog hluav taws xob txhua qhov taw qhia rau cov khoom siv hluav taws xob. Txog rau tam sim no, txawm li cas los xij, kev siv hluav taws xob thoob plaws lub tsheb los ntawm cov neeg siv khoom tau cuam tshuam los ntawm lub sij hawm them nqi ntev thiab tsis muaj kev them nqi. Kev nce qib hauv EV kev them nyiaj thev naus laus zis tau daws cov teeb meem no, ua kom muaj kev nyab xeeb thiab them sai sai hauv tsev thiab ntawm txoj kev. Cov khoom siv them nqi thiab kev tsim vaj tsev tau nce siab kom ua tau raws li qhov xav tau ntawm kev lag luam EV loj hlob sai, ua rau txoj hauv kev rau kev loj hlob ntawm kev thauj mus los hauv hluav taws xob.
DRIVING FORCES tom qab EV MARKET
Kev nqis peev hauv tsheb hluav taws xob tau loj hlob tau ntau xyoo, tab sis muaj kev mloog zoo thiab kev xav tau ntau ntxiv los ntawm ntau lub zej zog. Kev loj hlob tsom mus rau kev daws teeb meem huab cua tau hais txog qhov tseem ceeb ntawm lub tsheb hluav taws xob - lub peev xwm los txo cov pa roj carbon emissions los ntawm cov tshuab hluav taws xob sab hauv thiab nqis peev hauv kev thauj mus los huv si tau dhau los ua lub hom phiaj dav rau tsoomfwv thiab kev lag luam ib yam nkaus. Qhov no tsom mus rau kev loj hlob ruaj khov thiab kev txuag ntawm cov peev txheej ntuj kuj tseem ua rau kev siv thev naus laus zis mus rau txhua lub zej zog hluav taws xob - lub ntiaj teb uas tsis muaj zog raws li cov peev txheej txuas mus ntxiv yam tsis muaj teeb meem emissions.
Cov tsav tsheb ib puag ncig thiab thev naus laus zis no tau cuam tshuam txog qhov tseem ceeb ntawm tsoomfwv txoj cai thiab kev nqis peev, tshwj xeeb tshaj yog nyob rau hauv 2021 Infrastructure Investment and Jobs Act, uas tau npaj $ 7.5 nphom rau EV infrastructure ntawm tsoomfwv qib, $ 2.5 billion rau EV them thiab refueling infrastructure nyiaj pab, thiab $ 5 nphom rau National Electric Vehicle Charging Program. Biden Administration tseem tab tom nrhiav lub hom phiaj ntawm kev tsim thiab txhim kho 500,000 DC them chaw nres tsheb thoob plaws tebchaws.
Cov qauv no kuj tuaj yeem pom ntawm lub xeev. Cov xeev suav nrog California, Massachusetts, thiab New Jersey tab tom nrhiav txoj cai los tuav txhua lub tsheb hluav taws xob. Cov qhab nia se, Electrify America kev txav, kev txhawb siab, thiab cov lus txib tseem cuam tshuam rau cov neeg siv khoom thiab cov tuam txhab tsim khoom los tuav lub zog EV.
Automakers koom nrog kev txav mus rau lub tsheb fais fab, ib yam nkaus. Cov tuam txhab tsim hluav taws xob qub qub suav nrog GM, Ford, Volkswagen, BMW, thiab Audi tsis tu ncua qhia cov qauv EV tshiab. Thaum kawg ntawm 2022, yuav tsum muaj ntau tshaj 80 EV qauv thiab plug-in hybrids muaj nyob rau hauv kev ua lag luam. Muaj ntau tus neeg tsim khoom tshiab EV koom nrog kev ua lag luam, suav nrog Tesla, Lucid, Nikola, thiab Rivian.
Cov tuam txhab siv hluav taws xob tseem tab tom npaj rau txhua lub zej zog hluav taws xob. Nws yog ib qho tseem ceeb uas cov khoom siv hluav taws xob nyob ua ntej ntawm qhov nkhaus thaum nws los txog rau kev siv hluav taws xob txhawm rau txhawm rau ua kom tau raws li qhov xav tau nce ntxiv, thiab cov txheej txheem tseem ceeb suav nrog microgrids yuav xav tau nyob rau hauv interstates kom haum rau cov chaw nres tsheb fais fab. Kev sib txuas lus tsheb-rau-Grid kuj tau txais kev sib tw raws txoj kev loj.
ROADBLOCKS rau kev loj hlob
Thaum lub zog nce ntxiv rau kev siv EV thoob plaws, cov kev cov nyom yuav tsum muaj kev loj hlob zoo. Thaum cov kev txhawb siab yuav txhawb kom cov neeg siv khoom lossis cov tsheb thauj mus los hloov mus rau lub tsheb hluav taws xob, lawv tuaj yeem tuaj nrog kev ntes - tej zaum yuav muaj kev txav mus rau EVs kom muaj peev xwm sib txuas lus nrog cov txheej txheem los taug qab mais, xav tau kev tsim kho thev naus laus zis thiab kev sib txuas lus sab nraum zoov.
Ib qho ntawm cov teeb meem loj tshaj plaws rau EV kev saws me nyuam ntawm cov neeg siv khoom yog txhim khu kev qha thiab muaj txiaj ntsig kev them nqi. Kwv yees li 9.6 lab tus nqi chaw nres nkoj yuav xav tau los ntawm 2030 kom haum raws li kev kwv yees kev loj hlob ntawm EV lag luam. Yuav luag 80% ntawm cov chaw nres nkoj no yuav yog lub chargers hauv tsev, thiab kwv yees li 20% yuav yog cov chaw them nyiaj rau pej xeem lossis chaw ua haujlwm. Tam sim no, cov neeg siv khoom tsis txaus siab los yuav lub tsheb EV vim muaj kev ntxhov siab ntau - qhov kev txhawj xeeb tias lawv lub tsheb yuav tsis tuaj yeem taug kev ntev yam tsis tas yuav tsum tau them rov qab, thiab cov chaw them nyiaj yuav tsis muaj lossis siv tau thaum xav tau.
Pej xeem los yog sib koom chargers tshwj xeeb yuav tsum muaj peev xwm muab ze-qhov ceev ceev them peev xwm nyob ib ncig ntawm lub moos. Tus neeg tsav tsheb uas nres ntawm qhov chaw them nqi raws txoj kev loj yuav xav tau kev them nqi hluav taws xob sai - lub zog them hluav taws xob siab yuav tuaj yeem muab cov tsheb nyob ze rau lub roj teeb rov qab tag nrho tom qab tsuas yog ob peb feeb ntawm kev them nyiaj.
High-speed chargers xav tau kev tsim tshwj xeeb rau kev ua haujlwm kom ntseeg tau. Lub peev xwm ua kom txias yog tsim nyog los ua kom cov pins them nyiaj ntawm qhov kub thiab txias thiab ncua sij hawm lub tsheb tuaj yeem them nrog cov dej ntws siab dua. Nyob rau hauv lub tsheb-them them qhov chaw, ua kom cov pins tiv tauj txias yuav tsim kom muaj txiaj ntsig zoo thiab muaj kev ntseeg siab ruaj khov siab kom tau raws li qhov tsis tu ncua ntawm cov neeg siv khoom xav tau.
HIGH-POWERED CHARGER DESIGN CONSIDERATIONS
EV chargers tau nce zuj zus nrog kev tsom mus rau kev ua kom zoo dua qub thiab muaj peev xwm them lub zog siab kom ua tau raws li cov kev xav tau ntawm EV tsav tsheb thiab kov yeej ntau yam kev ntxhov siab. Lub tshuab hluav taws xob EV muaj zog nrog 500 amps yog ua tau nrog cov kua cua txias thiab kev saib xyuas - tus neeg nqa khoom sib txuas hauv cov khoom siv hluav taws xob muaj cov thermal conductivity thiab tseem ua haujlwm ua lub dab dej kub thaum lub coolant dissipates cua sov los ntawm kev sib xyaw ua ke cua txias ducts. Cov chargers no muaj ntau yam sensors, nrog rau cov coolant to sensors thiab xyuas qhov kub thiab txias ntawm txhua lub zog tiv tauj kom paub tseeb tias cov pins tsis tshaj 90 degrees Celsius. Yog hais tias qhov pib mus txog, lub charger nyob rau hauv lub chaw nres tsheb them yuav txo lub hwj chim tso zis kom tswj tau qhov kub thiab txias.
EV chargers kuj yuav tsum muaj peev xwm tiv taus hnav thiab tsim kua muag thiab yooj yim kho. EV charging handles yog tsim los rau hnav thiab tsim kua muag, kev tuav nruj dhau lub sijhawm cuam tshuam rau lub ntsej muag mating yog qhov kev zam. Ntau ntxiv, cov chargers tau tsim los nrog cov khoom siv modular, tso cai rau qhov yooj yim hloov ntawm lub ntsej muag mating.
Kev tswj cov kab hluav taws xob hauv cov chaw them nqi kuj yog ib qho tseem ceeb rau kev ua neej ntev thiab kev ntseeg siab. Cov kab hluav taws xob uas muaj hluav taws xob muaj zog muaj cov xov tooj tooj liab, cov kab ua kua dej txias, thiab cov kab hluav taws xob ua haujlwm tseem tseem yuav tsum tau tiv thaiv raug rub los yog tsav dhau. Lwm qhov kev txiav txim siab suav nrog cov lockable latches, uas tso cai rau tus neeg tsav tsheb tawm mus (Modularity ntawm lub ntsej muag mating nrog rau cov lus piav qhia ntawm cov dej txias ntws) lawv lub tsheb them ntawm qhov chaw nres tsheb pej xeem yam tsis muaj kev txhawj xeeb tias ib tus neeg tuaj yeem txiav lub cable.
