Bidirectional Charging yog dab tsi?

Nrog rau feem ntau EVs, hluav taws xob mus rau ib txoj kev - los ntawm lub charger, phab ntsa qhov hluav taws xob los yog lwm yam hwj chim qhov chaw rau hauv lub roj teeb. Muaj tus nqi pom tseeb rau cov neeg siv hluav taws xob thiab, nrog ntau tshaj li ib nrab ntawm tag nrho cov tsheb muag khoom xav tias yuav yog EVs los ntawm qhov kawg ntawm lub xyoo caum, ib qho kev nce ntxiv ntawm cov nqi hluav taws xob ntau dhau lawm.

Bidirectional charging cia koj txav zog mus rau lwm txoj kev, los ntawm lub roj teeb mus rau lwm yam uas tsis yog lub tsheb tsav tsheb. Thaum muaj hluav taws xob, EV txuas tau zoo tuaj yeem xa hluav taws xob rov qab mus rau lub tsev lossis kev lag luam thiab khaws lub zog rau ob peb hnub, txheej txheem hu ua tsheb-rau-tsev (V2H) lossis tsheb-rau-tsev (V2B).

Ntau lub siab xav, koj lub EV tseem tuaj yeem muab lub zog rau lub network thaum qhov kev thov siab - hais tias, thaum muaj cua sov thaum sawv daws tab tom khiav lawv lub tshuab cua txias - thiab zam kev tsis ruaj khov lossis tsaus muag. Qhov ntawd hu ua tsheb-rau-grid (V2G).

Xav tias feem ntau cov tsheb zaum nres 95% ntawm lub sijhawm, nws yog lub tswv yim ntxias.

Tab sis muaj ib lub tsheb uas muaj peev xwm bidirectional tsuas yog ib feem ntawm qhov sib npaug. Koj kuj xav tau lub charger tshwj xeeb uas tso cai rau lub zog ntws mus rau ob txoj hauv kev. Peb tuaj yeem pom tias thaum ntxov xyoo tom ntej: Lub Rau Hli, Montreal-based dcbel tshaj tawm tias nws qhov chaw nres tsheb r16 Lub Tsev Hluav Taws Xob tau dhau los ua thawj qhov kev sib tw EV charger tau ntawv pov thawj rau kev siv nyob hauv Asmeskas.

Lwm lub charger bidirectional, Quasar 2 los ntawm Wallbox, yuav muaj rau Kia EV9 hauv thawj ib nrab ntawm 2024.

Ib cag ntawm cov khoom siv kho vajtse, koj tseem yuav xav tau daim ntawv cog lus sib cuam tshuam los ntawm koj lub tuam txhab hluav taws xob, kom ntseeg tau tias kev xa hluav taws xob xa hluav taws xob yuav tsis dhau ntawm daim phiaj.

Thiab yog tias koj xav rov qab qee qhov ntawm koj cov peev txheej nrog V2G, koj yuav xav tau software uas tswj hwm lub kaw lus kom tswj tau qib ntawm tus nqi koj nyiam thaum tau txais koj tus nqi zoo tshaj plaws rau lub zog koj muag rov qab. Cov neeg ua si loj hauv thaj chaw ntawd yog Fermata Energy, Charlottesville, Virginia-based tuam txhab tsim hauv 2010.

"Cov neeg siv khoom sau npe rau peb lub platform thiab peb ua txhua yam khoom siv," hais tias tus tsim David Slutzky. "Lawv tsis tas yuav xav txog nws."

Fermata tau koom tes nrog ntau tus neeg tsav dav hlau V2G thiab V2H thoob plaws Asmeskas. Nyob rau ntawm Alliance Center, qhov chaw ua haujlwm sib koom ua ke nyob rau hauv Denver, Nissan Leaf yog ntsaws rau hauv Fermata bidirectional charger thaum nws tsis tau tsav ncig. Lub chaw hais tias Fermata qhov kev thov-peak twv ua ntej software muaj peev xwm txuag tau $ 300 ib hlis ntawm nws daim nqi hluav taws xob nrog dab tsi hu ua tom qab-tus-meter xav tau kev tswj hwm.

Nyob rau hauv Burrillville, Rhode Island, ib nplooj nres ntawm qhov chaw kho dej khib nyiab tau txais yuav luag $ 9,000 nyob rau ob lub caij ntuj sov, raws li Fermata, los ntawm kev tso hluav taws xob rov qab rau hauv kab sib chaws thaum lub caij ntuj sov.

Tam sim no feem ntau cov teeb tsa V2G yog qhov kev sim ua lag luam me me. Tab sis Slutzky hais tias kev pabcuam hauv vaj tse yuav sai sai no txhua qhov chaw.

"Qhov no tsis yog yav tom ntej," nws hais. “Nws twb tshwm sim lawm, tiag tiag. Nws tsuas yog hais tias nws tab tom yuav ntsuas. "

Bidirectional charging: tsheb mus tsev
Daim ntawv yooj yim tshaj plaws ntawm lub zog bidirectional hu ua tsheb thauj khoom, lossis V2L. Nrog nws, koj tuaj yeem them cov khoom siv mus pw hav zoov, cov cuab yeej hluav taws xob lossis lwm lub tsheb hluav taws xob (hu ua V2V). Muaj cov ntaub ntawv siv ntau dua: Xyoo tas los, Texas urologist Christopher Yang tshaj tawm tias nws tau ua tiav kev phais mob thaum lub sijhawm muaj hluav taws xob los ntawm kev siv nws cov cuab yeej nrog lub roj teeb hauv nws lub Rivian R1T khaws.

Tej zaum koj kuj yuav hnov ​​lo lus V2X, lossis tsheb rau txhua yam. Nws yog me ntsis ntawm qhov tsis meej pem catchall uas tuaj yeem yog lub ntsiab lus rau V2H lossis V2G lossis txawm tias tsuas yog tswj kev them nyiaj, hu ua V1G. Tab sis lwm tus neeg hauv kev lag luam tsheb siv cov ntawv luv luv, hauv cov ntsiab lus sib txawv, txhais tau tias txhua yam kev sib txuas lus ntawm lub tsheb thiab lwm qhov chaw, suav nrog cov neeg taug kev, teeb pom kev zoo lossis cov chaw khiav tsheb.

Ntawm qhov sib txawv ntawm kev them nyiaj bidirectional, V2H muaj kev txhawb nqa dav tshaj plaws, raws li tib neeg kev hloov pauv huab cua thiab cov kab hluav taws xob tswj tsis zoo tau ua rau muaj kev cuam tshuam ntau dua. Muaj ntau dua 180 qhov kev cuam tshuam cuam tshuam thoob plaws hauv Asmeskas xyoo 2020, raws li Wall Street Journal tshuaj xyuas ntawm tsoomfwv cov ntaub ntawv, nce los ntawm tsawg dua ob lub kaum os hauv 2000.

EV roj teeb cia muaj ntau yam txiaj ntsig ntawm cov tshuab hluav taws xob diesel lossis propane, suav nrog qhov ntawd, tom qab muaj kev puas tsuaj, hluav taws xob feem ntau rov qab sai dua li lwm cov khoom siv roj. Thiab cov tshuab hluav taws xob ib txwm muaj suab nrov thiab cumbersome thiab hnoos tsis muaj pa phem.

Ib cag ntawm kev muab lub zog thaum muaj xwm txheej ceev, V2H tuaj yeem txuag tau koj cov nyiaj: Yog tias koj siv lub zog khaws cia rau lub zog koj lub tsev thaum hluav taws xob ntau dua, koj tuaj yeem txo koj cov nqi hluav taws xob. Thiab koj tsis xav tau daim ntawv cog lus sib txuas vim tias koj tsis thawb hluav taws xob rov qab rau hauv daim phiaj.

Tab sis siv V2H nyob rau hauv ib tug blackout tsuas yog ua rau lub ntsiab lus, hais tias lub zog kws tshuaj ntsuam Eisler.

Nws hais tias "Yog tias koj tab tom saib qhov xwm txheej uas daim phiaj xwm tsis tuaj yeem ntseeg tau thiab tseem tuaj yeem tsoo, koj yuav tsum nug koj tus kheej, qhov kev sib tsoo yuav kav ntev npaum li cas," nws hais. "Koj puas yuav tuaj yeem them rov qab EV thaum koj xav tau?"

Ib qho kev thuam zoo sib xws los ntawm Tesla - thaum tib lub sijhawm cov tub ua lag luam hnub sib tham hauv lub Peb Hlis uas nws tshaj tawm tias nws yuav ntxiv kev ua haujlwm bidirectional. Ntawm qhov xwm txheej ntawd, CEO Elon Musk downplayed lub feature li "tsis yooj yim heev."

"Yog tias koj tshem koj lub tsheb, koj lub tsev yuav tsaus," nws hais. Tau kawg, V2H yuav yog tus neeg sib tw ncaj qha rau Tesla Powerwall, Musk tus tswv lub hnub ci roj teeb.

Bidirectional charging: tsheb rau daim phiaj

Cov tswv tsev nyob hauv ntau lub xeev tuaj yeem muag cov khoom siv hluav taws xob ntau ntxiv uas lawv tsim nrog cov hnub ci vaj huam sib luag ru tsev rov qab rau hauv daim phiaj. Yuav ua li cas yog tias ntau tshaj 1 lab EVs xav tias yuav muag hauv Asmeskas xyoo no tuaj yeem ua tau zoo ib yam?

Raws li cov kws tshawb fawb ntawm University of Rochester, cov neeg tsav tsheb tuaj yeem txuag tau ntawm $ 120 thiab $ 150 ib xyoos ntawm lawv daim nqi hluav taws xob.

V2G tseem nyob rau hauv nws cov me nyuam mos - cov tuam txhab hluav taws xob tseem tab tom nrhiav seb yuav npaj cov phiaj xwm li cas thiab yuav ua li cas them cov neeg siv khoom muag lawv kilowatt teev. Tab sis cov phiaj xwm tsav tsheb tau pib thoob ntiaj teb: California's Pacific Gas thiab Hluav Taws Xob, Asmeskas cov khoom siv loj tshaj plaws, tau pib tso npe rau cov neeg siv khoom hauv $ 11.7 lab tus kws tsav dav hlau los txiav txim seb nws yuav ua li cas thaum kawg ua ke ob txoj kev.

Raws li txoj kev npaj, cov neeg siv khoom nyob hauv tsev yuav tau txais txog li $ 2,500 rau tus nqi ntawm kev txhim kho lub tshuab hluav taws xob bidirectional thiab yuav raug them kom xa hluav taws xob rov qab rau hauv kab sib chaws thaum muaj kev xav tsis txaus. Nyob ntawm qhov hnyav ntawm qhov xav tau thiab lub peev xwm cov neeg txaus siab tso tawm, cov neeg tuaj koom tuaj yeem khwv tau li ntawm $ 10 thiab $ 50 rau ib qho kev tshwm sim, PG&E tus cev lus Paul Doherty hais rau dot.LA thaum Lub Kaum Ob Hlis,

PG&E tau teeb tsa lub hom phiaj ntawm kev txhawb nqa 3 lab EVs hauv nws qhov chaw pabcuam los ntawm 2030, nrog ntau dua 2 lab ntawm lawv muaj peev xwm txhawb nqa V2G.
