V2H V2G V2L Dab tsi yog siv ntawm kev them nyiaj bidirectional?

Dab tsi yog kev siv ntawm bidirectional charging?
Bidirectional chargers tuaj yeem siv rau ob daim ntawv thov sib txawv. Thawj thiab feem ntau tham txog yog Tsheb-rau-daim phiaj lossis V2G, tsim los xa lossis xa tawm lub zog rau hauv daim phiaj hluav taws xob thaum qhov kev thov siab. Yog tias ntau txhiab lub tsheb nrog V2G thev naus laus zis tau txuas thiab ua haujlwm, qhov no muaj peev xwm hloov pauv li cas hluav taws xob khaws cia thiab tsim tawm ntawm qhov loj. EVs muaj cov roj teeb loj, muaj zog, yog li kev sib xyaw ua ke ntawm ntau txhiab lub tsheb nrog V2G tuaj yeem loj heev. Nco ntsoov tias V2X yog ib lo lus uas qee zaum siv los piav txog peb qhov kev hloov pauv tau piav qhia hauv qab no.

Tsheb-rau-daim phiaj lossis V2G - EV xa tawm lub zog los txhawb txoj kab hluav taws xob.
Tsheb-rau-tsev lossis V2H - EV lub zog yog siv los ua lub zog hauv tsev lossis kev lag luam.
Lub tsheb-rau-load lossis V2L * - EV tuaj yeem siv rau cov khoom siv hluav taws xob lossis them lwm cov EVs
* V2L tsis xav tau lub charger bidirectional los ua haujlwm

Qhov thib ob siv ntawm bidirectional EV chargers yog rau Tsheb-rau-tsev lossis V2H. Raws li cov npe qhia, V2H ua kom lub EV siv tau zoo li lub tsev roj teeb hauv tsev kom khaws cov hnub ci ntau dhau thiab lub zog koj lub tsev. Piv txwv li, cov roj teeb hauv tsev ib txwm muaj, xws li Tesla Powerwall, muaj peev xwm ntawm 13.5kWh. Hauv qhov sib piv, qhov nruab nrab EV muaj peev xwm ntawm 65kWh, sib npaug li yuav luag tsib Tesla Powerwalls. Vim lub roj teeb muaj peev xwm loj, lub EV them tag nrho tuaj yeem txhawb nqa lub tsev nruab nrab rau ob peb hnub sib law liag lossis ntev dua thaum ua ke nrog lub hnub ci ru tsev.

tsheb-rau-grid - V2G
Tsheb-rau-daim phiaj (V2G) yog qhov chaw me me ntawm cov roj teeb EV khaws cia rau hauv daim phiaj hluav taws xob thaum xav tau, nyob ntawm qhov kev pabcuam. Txhawm rau koom nrog V2G cov kev pab cuam, yuav tsum muaj ob lub DC charger thiab EV sib xws. Tau kawg, muaj qee qhov kev txhawb nqa nyiaj txiag los ua qhov no thiab EV cov tswv tau txais qhab nia lossis txo nqi hluav taws xob. EVs nrog V2G tuaj yeem ua rau tus tswv tuaj yeem koom nrog hauv qhov kev pabcuam hluav taws xob virtual (VPP) txhawm rau txhim kho daim phiaj kev ruaj ntseg thiab muab lub zog thaum lub sijhawm xav tau. Tsuas yog ib tug puv tes ntawm EVs tam sim no muaj V2G thiab bidirectional DC them peev xwm; Cov no suav nrog cov qauv tom qab Nissan Leaf (ZE1) thiab Mitsubishi Outlander lossis Eclipse plug-in hybrids.

V2G bidirectional charging

Txawm hais tias muaj kev tshaj tawm, ib qho ntawm cov teeb meem nrog kev dov tawm ntawm V2G thev naus laus zis yog qhov kev sib tw ntawm kev tswj hwm thiab tsis muaj cov txheej txheem kev them nyiaj thib ob thiab cov khoom sib txuas. Bidirectional chargers, zoo li hnub ci inverters, yog suav tias yog lwm hom kev tsim hluav taws xob thiab yuav tsum ua kom tau raws li txhua qhov kev tswj hwm kev nyab xeeb thiab kaw cov qauv hauv qhov xwm txheej ntawm daim phiaj tsis ua haujlwm. Txhawm rau kov yeej cov kev nyuaj no, qee lub tuam txhab tsheb, xws li Ford, tau tsim cov txheej txheem AC bidirectional charging yooj yim uas tsuas yog ua haujlwm nrog Ford EVs los muab lub zog rau hauv tsev es tsis xa tawm mus rau hauv daim phiaj. Lwm tus, xws li Nissan, ua haujlwm siv universal bidirectional chargers xws li Wallbox Quasar, tau piav qhia hauv qab no. Kawm paub ntxiv txog cov txiaj ntsig ntawm V2G thev naus laus zis.
Tam sim no, feem ntau EVs tau nruab nrog tus qauv CCS DC charge port. Tam sim no, tsuas yog EV uas siv CCS chaw nres nkoj rau kev them nyiaj bidirectional yog qhov nyuam qhuav tso tawm Ford F-150 Lightning EV. Txawm li cas los xij, ntau EVs nrog CCS cov chaw nres nkoj sib txuas yuav muaj nrog V2H thiab V2G muaj peev xwm nyob rau yav tom ntej, nrog VW tshaj tawm nws cov tsheb hluav taws xob ID tuaj yeem muab kev them nyiaj ob lub sijhawm hauv 2023.
2. Tsheb mus tsev – V2H
Tsheb-rau-tsev (V2H) zoo ib yam li V2G, tab sis lub zog yog siv hauv zos los txhawb lub tsev es tsis txhob pub rau hauv daim phiaj hluav taws xob. Qhov no ua rau EV ua haujlwm zoo li cov roj teeb hauv tsev ib txwm muaj los pab txhawb tus kheej kom txaus, tshwj xeeb tshaj yog thaum ua ke nrog lub hnub ci ntsa iab. Txawm li cas los xij, qhov txiaj ntsig pom tseeb tshaj plaws ntawm V2H yog lub peev xwm los muab lub zog thaub qab thaum lub teeb hluav taws xob.

V2H bidirectional charger

Rau V2H ua haujlwm, nws yuav tsum tau siv lub tshuab hluav taws xob bidirectional EV thiab cov khoom siv ntxiv, suav nrog lub ntsuas hluav taws xob (CT meter) ntsia ntawm lub ntsiab lus sib txuas. CT meter saib xyuas lub zog ntws mus rau thiab los ntawm daim phiaj. Thaum lub kaw lus pom daim phiaj siv hluav taws xob siv los ntawm koj lub tsev, nws qhia lub bidirectional EV charger kom tso tawm tus nqi sib npaug, yog li offsetting lub zog los ntawm daim phiaj. Ib yam li ntawd, thaum lub kaw lus pom lub zog raug xa tawm los ntawm lub hnub ci ru tsev, nws cuam tshuam qhov no kom them EV, uas zoo ib yam li qhov ntse EV chargers ua haujlwm. Txhawm rau ua kom lub zog thaub qab thaum muaj kev kub ntxhov lossis kev kub ntxhov, V2H system yuav tsum tuaj yeem ntes cov kab hluav taws xob hluav taws xob thiab cais tawm ntawm lub network siv lub tshuab hluav taws xob tsis siv neeg (hloov). Qhov no yog lub npe hu ua Islanding, thiab lub bidirectional inverter tseem ceeb ua hauj lwm raws li ib tug off-grid inverter siv lub EV roj teeb. Daim phiaj sib cais cov cuab yeej yuav tsum tau ua kom muaj kev ua haujlwm thaub qab, zoo li hybrid inverters siv hauv cov roj teeb thaub qab.
