Ukushaja Okwabelwana Ngayo: Izindlela Zokuhweba ze-DC V2G

Impendulo Esheshayo

Indlela yezentengiselwano yeImoto-ukuya-kuGridi (V2G)Ukukhokhisa kuyashintsha kusuka ekuhlolweni kokuhlola kuya kumamodeli emali engenayo angandiswa. NgokusebenzisaI-ISO 15118-20Amashaja e-DC ahambisana nezinhlangothi ezimbili, izindiza ze-EV kanye nabanikazi abazimele bangathengisa amandla emuva kugridi ngesikhathi samahora aphezulu noma banikeze izinsizakalo zokulawula imvamisa. Le modeli "Yokushaja Okwabelwana Ngayo" iguqula ama-EV abe yizimpahla zokugcina amandla eselula, okunciphisa kakhulu Izindleko Zobunikazi (i-TCO) zabaqhubi bezindiza futhi inikeze ithuluzi elibalulekile lokuzinzisa izinsiza.

Izinto Ezibalulekile Okufanele Uzicabangele

• Ukudluliswa Kwamandla Okuqondiswa Kwezinhlangothi Zombili (i-BPT): Inika amandla ama-EV kokubili ukudonsa nokukhipha amandla, okuhambisana ne-ISO 15118-20.
• Ukukhiqizwa Kwemali Engenayo: Abasebenzi bangazuza ngokushefa okuphezulu, impendulo yesidingo, kanye nokulawulwa kwemvamisa yegridi.
• Ukuzinza kweGridi: I-V2G isiza ukulinganisela igridi njengoba ukungena kwamandla avuselelekayo (umoya/ilanga) kukhuphuka.
• Ukulungela Kobuchwepheshe: Amamojula amabili asekelwe ku-SiC afinyelela ukusebenza kahle okuphezulu kokubili emijikelezweni yokushaja kanye nokukhipha ishaja.
• Ukuthuthukiswa Kwezikebhe: I-V2B (Imoto Eya Esakhiweni) inciphisa izindleko zesidingo sezentengiselwano ngokusebenzisa amabhethri e-EV njengezipele zesakhiwo.
• Amazinga: Kusekelwa yi-IEC 61851-23:2023 kanye nezinqubo zakamuva ze-CCS2/NACS.
• Isimiso sezinto eziphilayo: Kudinga ukubambisana phakathi kwabakhiqizi be-EV, ama-OEM amashaja (njenge-MIDA), kanye nezinsiza.

Ukucwila Okujulile: Amandla Ezentengiselwano e-V2G

1. Kusukela ku-V2L kuya ku-V2G: Ukuvela Kokushaja Okuqondiswayo

Nakuba i-Vehicle-to-Load (V2L) isivamile ezimotweni zabagibeli zokusebenzisa imishini yokukhempa, inani langempela lezentengiselwano liseIzixazululo zokushaja ze-V2G. I-V2G ivumela ukusebenzisana okuyinkimbinkimbi lapho imoto isebenza njengomthombo wamandla osabalalisiwe (i-DER).

2. Ukwenza Imali Ngebhethri: Amamodeli Ebhizinisi

Umnotho "wokukhokhisa ngokuhlanganyela" uchuma ngezinsika ezintathu eziyinhloko:

• I-Arbitrage: Ukushaja ebusuku (amanani aphansi) kanye nokukhipha ngesikhathi samahora aphezulu (amanani aphezulu).
• Izinsizakalo Ezisekelayo: Ukunikeza ukulawulwa kwemvamisa yokuphendula okusheshayo kugridi, okuvame ukuba nenzuzo enkulu kunokuthengisa kwamandla okulula.
• Ukuphathwa Kwezindleko Zokufuna: UkusebenzisaIziteshi zokushaja ezihlanganisiwe ze-BESSkanye ne-V2B ukuqinisekisa ukuthi isakhiwo sezentengiselwano asidluli isilinganiso saso samandla.

3. Izidingo Zobuchwepheshe: Inzuzo ye-MIDA

I-MIDA iqondisa izinhlangothi zombiliAmamojula kagesi e-EVsebenzisa ubuchwepheshe be-Silicon Carbide (SiC) ukuqinisekisa ukuthi ukusebenza kahle kwamandla okuya nokubuya kuthuthukiswa kakhulu. Lokhu kubalulekile ngoba iphesenti ngalinye lokulahlekelwa ngesikhathi sokukhishwa lidla ngqo inzuzo yomqhubi.

• Ububanzi Bevolumu Ebanzi: Isekela i-150V kuya ku-1000V, iqinisekisa ukuhambisana nezakhiwo zezimoto ze-400V zamanje kanye nezakhiwo zezimoto ze-800V/1000V zesikhathi esizayo.
• Ukuxhumana: Ukusetshenziswa okugcwele kwe-ISO 15118-20 stack ukuze kuqinisekiswe ukuthi “i-Plug & Charge” kanye nokuxhawulana okuqondiswe ohlangothini ngalunye.

4. Ukusebenzisana kweGridi kanye nengqalasizinda ehlakaniphile

Ukuze kulinganiswe i-V2G, amashaja kumele ahlanganiswe ku-uhlelo lokushaja lwe-EV lwesitoreji selanga kanye nesitorejiLokhu kuvumela isiteshi sokushaja ukuthi siphathe ukukhiqizwa kwendawo (ilanga), isitoreji sendawo (i-BESS), kanye nesitoreji seselula (ama-EV) njengesitshalo samandla esisodwa esibonakalayo (i-VPP).

Imibuzo Evame Ukubuzwa

1. Ingabe ikhona i-EV engenza i-V2G?Cha, i-EV kumele ibe neshaja ejikelezayo (ye-AC V2G) noma isekele ukushaja kwe-DC okujikelezayo (ye-DC V2G), kanye nezinqubo zokuxhumana ezidingekayo.

2. Ngingazuza malini nge-V2G?Imali engenayo iyahlukahluka ngokwemakethe kanye nezikhuthazo zezinsizakusebenza, kodwa abaqhubi bezimoto ezimakethe ze-V2G ezisebenzayo bangabona izinkulungwane zamaRandi ekongeni noma emalini engenayo ngemoto ngayinye minyaka yonke.

3. Ingabe i-V2G iyalimaza ibhethri lemoto?Ama-algorithm e-BMS yesimanje kanye ne-smart V2G anciphisa ukuguguleka komjikelezo. Ngokuvamile, imali engenayo etholakalayo idlula kakhulu ukuwohloka kwebhethri okungaphansi.

4. Uyini umehluko phakathi kwe-V2G ne-V2B?I-V2G ithumela ugesi kugridi yomphakathi, kuyilapho i-V2B (Imoto eya eSakhiweni) isebenzisa imoto ukukhanyisa isakhiwo esithile, ngokuvamile ukugwema izindleko zokufuna okuphezulu.

5. Ingabe ihadiwe ye-MIDA isilungele i-V2G?Yebo, okwakamuva kwethuIzixazululo zokushaja ze-V2Gzakhiwe ngokwezinga le-ISO 15118-20 futhi zilungele ukuthunyelwa kwezentengiselwano.

6. Ingabe ngidinga isixhumi esikhethekile se-V2G?Izixhumi ezijwayelekile ze-CCS2, NACS, kanye ne-CHAdeMO zisekela i-V2G, uma nje ihadiwe yangaphakathi kanye nesofthiwe kuqondiswa kabili.

7. Izinsiza ziyibona kanjani i-V2G?Izinsizakusebenza ziya ngokuya zibona i-V2G njengethuluzi eliwusizo lokuzinzisa igridi kanye nendlela yokugwema ukusebenza kwesitshalo esibizayo esikhuphukayo.
