Chii chinonzi Bidirectional Charging?

NemaEV mazhinji, magetsi anoenda nenzira imwe chete - kubva pachaja, pamadziro kana kune rimwe simba rinopinda mubhatiri. Pane mutengo uri pachena kune mushandisi wemagetsi uye, nemutengo unodarika hafu wekutengesa mota dzese unotarisirwa kunge uri maEV pakupera kwemakore gumi, mutoro uri kuwedzera pamagetsi emagetsi akatove akawandisa.

Kuchaja magetsi nenzira mbiri kunoita kuti ufambise simba neimwe nzira, kubva pabhatiri kuenda kune chimwe chinhu chisiri mota inotyaira. Kana mota yadzima, EV yakabatana zvakanaka inogona kutumira magetsi kumba kana kubhizinesi uye kuchengetedza magetsi kwemazuva akati wandei, maitiro anozivikanwa semotokari kuenda kumba (V2H) kana mota kuenda kuvaka (V2B).

Zvikuru, EV yako inogonawo kupa simba kune network kana kudiwa kwacho kwakanyanya - ngatitii, panguva yekupisa apo munhu wese ari kushandisa ma air conditioner ake - uye kudzivirira kusagadzikana kana kudzimwa kwemagetsi. Izvi zvinozivikanwa se vehicle-to-grid (V2G).

Tichifunga kuti mota zhinji dzinogara dzakamiswa 95% yenguva, inzira inokwezva.

Asi kuva nemota ine simba rekufamba netsoka mbiri ingori chikamu cheequation yacho. Unodawo charger yakakosha inobvumira simba kufamba netsoka mbiri. Taigona kuona izvozvo kubva mugore rinouya: Muna Chikumi, dcbel iri kuMontreal yakazivisa kuti r16 Home Energy Station yayo yakanga yava charger yekutanga yemagetsi emagetsi maviri yakapihwa chitupa chekushandisa mudzimba muUS.

Imwe charger yemagetsi inoenda kumativi maviri, Quasar 2 kubva kuWallbox, ichavepo yeKia EV9 muhafu yekutanga ya2024.

Kunze kwemidziyo yemagetsi, muchadawo chibvumirano chekubatanidza magetsi kubva kukambani yenyu yemagetsi, ichiva nechokwadi chekuti kutumira magetsi kumusoro hakuzokanganisi grid.

Uye kana uchida kudzosa mari yawakadyara neV2G, uchada software inotungamira sisitimu kuti ichengetedze mwero wemari yaunonzwa wakasununguka nayo uku ichikupa mutengo wakanakisa wesimba raunodzosera. Mutambi mukuru munharaunda iyoyo iFermata Energy, kambani iri kuCharlottesville, Virginia yakavambwa muna 2010.

"Vatengi vanonyorera kupuratifomu yedu uye isu tinoita zvese izvozvo," anodaro muvambi David Slutzky. "Havafanirwe kufunga nezvazvo."

Fermata yakabatana mumakambani akawanda eV2G neV2H muUS yese. KuAlliance Center, nzvimbo yekushandira pamwe chete muDenver ine chinangwa chekuchengetedza nharaunda, Nissan Leaf inobatanidzirwa muFermata bidirectional charger kana isiri kufamba-famba. Nzvimbo iyi inoti software yeFermata yekufungidzira demand-peak inokwanisa kuchengetedza $300 pamwedzi pabhiri rayo remagetsi nezvinonzi behind-the-meter demand charge management.

MuBurrillville, Rhode Island, imwe nzvimbo yeLeaf yakapakwa pafekitori yekuchenesa mvura yakasviba yakawana mari inosvika $9,000 mumazhizha maviri, sekureva kwaFermata, nekudzosera magetsi kugrid panguva yezviitiko zvekupisa zvakanyanya.

Parizvino maV2G akawanda anoshandiswa mukuyedza mabhizimisi madiki. Asi Slutzky anoti mabasa ekuchengetedza dzimba achave aripo munguva pfupi iri kutevera.

"Izvi hazvisi mune ramangwana," anodaro. "Zviri kutoitika, zvechokwadi. Kungoti zvava kuda kukura."

Kuchaja divi rimwe nerimwe: mota kuenda kumba
Rudzi rwesimba riri nyore kwazvo rwema "bidirectional power" runozivikanwa se "vehicle to load", kana kuti V2L. Naro, unogona kuchaja michina yekukamba, maturusi emagetsi kana imwe mota yemagetsi (inozivikanwa seV2V). Kune mamwe mashandisirwo anoshamisa enyaya: Gore rapfuura, chiremba wezvematumbu wekuTexas Christopher Yang akazivisa kuti akanga apedza vasectomy panguva yekudzimwa kweropa nekushandisa bhatiri muRivian R1T pickup yake.

Unogonawo kunzwa izwi rekuti V2X, kana kuti mota kuzvinhu zvese. Ishoko rinovhiringidza rinogona kushandiswa kureva V2H kana V2G kana kungochaja chete, rinozivikanwa seV1G. Asi vamwe vari muindasitiri yemotokari vanoshandisa chidimbu ichi, mune imwe nzira, kureva chero rudzi rwekutaurirana pakati pemotokari nechimwe chinhu, kusanganisira vanofamba netsoka, mwenje yemumugwagwa kana nzvimbo dzeruzivo rwemigwagwa.

Pakusiyana-siyana kwekuchaja kwemagetsi munzira mbiri, V2H ndiyo inonyanya kutsigirwa, sezvo shanduko yemamiriro ekunze inokonzerwa nevanhu uye magrid emagetsi asina kutarisirwa zvakanaka zvakaita kuti magetsi adzime zvakanyanya. Pakave nekukanganiswa kwakapararira kunopfuura 180 muUS muna 2020, zvichienderana neongororo yeWall Street Journal yedata rehurumende, kubva pasi pemakumi maviri nemana muna 2000.

Kuchengetedza mabhatiri emagetsi (EV) kune mabhenefiti akati wandei pane majenareta edhiziri kana propane, kusanganisira kuti, mushure menjodzi, magetsi anowanzo dzorerwa nekukurumidza kupfuura mamwe mafuta. Uye majenareta echinyakare ane ruzha uye anorema uye anoburitsa utsi hune chepfu.

Kunze kwekupa magetsi ekukurumidza, V2H inogona kukubatsira kuchengetedza mari: Kana ukashandisa magetsi akachengetwa kuendesa magetsi kumba kwako kana mitengo yemagetsi yakakwira, unogona kuderedza mabhiri ako emagetsi. Uye haudi chibvumirano chekubatanidza magetsi nekuti hausi kudzosera magetsi kugrid.

Asi kushandisa V2H panguva yekudzima magetsi kunongonzwisisika kusvika padanho rimwe chete, anodaro nyanzvi yezvemagetsi Eisler.

"Kana uri kutarisa mamiriro ezvinhu apo grid isingavimbike uye ingatodonha, unofanira kuzvibvunza kuti, tsaona iyoyo icharamba kwenguva yakareba sei," anodaro. "Uchakwanisa here kuchaja EV iyoyo kana uchida?"

Kutsoropodzwa kwakafanana kwakabva kuna Tesla - panguva yemusangano wevatori venhau wezuva rimwe chete wevanoisa mari munaKurume apo yakazivisa kuti yaizowedzera mashandiro maviri. Pachiitiko ichocho, CEO Elon Musk haana kuratidza kuti chiitiko ichi "chakanyanya kuomera."

“Kana ukabvisa plug yemotokari yako, imba yako inosviba,” akadaro. Ehe, V2H yaizokwikwidza zvakananga neTesla Powerwall, bhatiri rezuva raMusk.

Kuchaja divi rimwe nerimwe: mota kuenda kugrid

Varidzi vedzimba mumatunhu mazhinji vanogona kutotengesa simba rakawanda ravanogadzira vachishandisa ma solar panels edenga kugrid. Ko kana ma EV anopfuura miriyoni imwe anotarisirwa kutengeswa muUS gore rino aigona kuita zvimwe chetezvo?

Sekureva kwevaongorori vekuYunivhesiti yeRochester, vatyairi vanogona kuchengetedza mari iri pakati pemadhora zana nemakumi maviri kusvika zana nemakumi mashanu pagore pabhiri ravo remagetsi.

V2G ichiri kutanga — makambani emagetsi achiri kutsvaga nzira yekugadzirira grid uye nzira yekubhadhara vatengi vanovatengesa ma kilowatt hours. Asi mapurogiramu ekuedza ari kutanga pasi rose: Pacific Gas and Electric yekuCalifornia, kambani huru muUS, yatanga kunyoresa vatengi muchirongwa chekuedza chinodhura $11.7 miriyoni kuti vaone kuti chichazobatanidza sei nzira mbiri idzi.

Pasi pechirongwa ichi, vatengi vedzimba vachawana mari inosvika $2,500 yekuisa charger yemagetsi maviri uye vachabhadharwa kuti vadzosere magetsi kugrid kana paine kushomeka kunotarisirwa. Zvichienderana nekuoma kwezvinodiwa uye kugona kwevanhu kuburitsa magetsi, vatori vechikamu vanogona kuwana mari iri pakati pe $10 ne $50 pachiitiko chimwe nechimwe, mutauriri wePG&E Paul Doherty akaudza dot.LA muna Zvita,

PG&E yakaisa chinangwa chekutsigira maEV emagetsi mamiriyoni matatu munzvimbo yayo yekushandira panosvika gore ra2030, uye anopfuura mamiriyoni maviri acho anokwanisa kutsigira V2G.
