Kuchaja Kogawana: Njira Zamalonda za DC V2G

Yankho Lachangu

Njira yamalonda yaGalimoto Yopita ku Gridi (V2G)Kulipira kukusintha kuchoka pa kuyesa koyesa kupita ku njira zopezera ndalama zochulukirapo. Pogwiritsa ntchitoISO 15118-20Ma charger a DC otsatira njira ziwiri, ma EV fleet ndi eni ake achinsinsi amatha kugulitsa mphamvu ku grid nthawi yomwe anthu ambiri amagwira ntchito kapena kupereka ntchito zowongolera ma frequency. Mtundu uwu wa "Sharing Charging" umasintha ma EV kukhala zinthu zosungira mphamvu zama foni, zomwe zimachepetsa kwambiri Mtengo Wonse wa Umwini (TCO) kwa ogwira ntchito zama fleet ndikupereka chida chofunikira kwambiri chokhazikika pamagetsi.

Mfundo Zofunika Kwambiri

• Kusamutsa Mphamvu Yozungulira Mbali Ziwiri (BPT): Imathandiza ma EV kukoka ndi kutulutsa mphamvu, mogwirizana ndi ISO 15118-20.
• Kupanga NdalamaOgwira ntchito amatha kupeza phindu kudzera mu kumeta movutikira, kuyankha kwa kufunikira, komanso kulamulira pafupipafupi pa gridi.
• Kukhazikika kwa Gridi: V2G imathandiza kulinganiza bwino gridi pamene mphamvu zongowonjezwdwanso (mphepo/dzuwa) zikuchulukirachulukira.
• Kukonzekera kwaukadaulo: Ma module a SiC okhala ndi ma directional awiri amakhala ndi mphamvu zambiri pakuchaja ndi kutulutsa mphamvu.
• Kukonza Magalimoto: V2B (Kupita ku Nyumba) imachepetsa ndalama zogulira magalimoto pogwiritsa ntchito mabatire a EV ngati zinthu zosungiramo katundu.
• Miyezo: Yothandizidwa ndi IEC 61851-23:2023 ndi ma protocol aposachedwa a CCS2/NACS.
• Zachilengedwe: Imafuna mgwirizano pakati pa opanga magalimoto a EV, ma OEM ochaja (monga MIDA), ndi mautumiki.

Kusambira Kwambiri: Kuthekera kwa Malonda kwa V2G

1. Kuchokera ku V2L kupita ku V2G: Kusintha kwa Kuchaja kwa Maulendo Awiri

Ngakhale kuti galimoto yonyamula katundu (V2L) tsopano ndi yofala m'magalimoto onyamula anthu kuti aziyendetsa zida zoyendera m'misasa, mtengo weniweni wamalonda uli muMayankho ochapira a V2GV2G imalola kuyanjana kwapamwamba komwe galimoto imagwira ntchito ngati gwero lamphamvu logawidwa (DER).

2. Kupeza Ndalama ndi Batri: Ma Model a Bizinesi

Chuma cha "Kugawana Ndalama" chikuyenda bwino pazipilala zitatu zazikulu:

• Arbitrage: Kuchaja usiku (mitengo yotsika) ndi kutulutsa mphamvu nthawi yomwe ntchito ikuyenda bwino (mitengo yokwera).
• Ntchito Zothandizira: Kupereka malamulo ofulumira a ma frequency ku gridi, zomwe nthawi zambiri zimakhala zopindulitsa kuposa kugulitsa mphamvu zosavuta.
• Kuyang'anira Ndalama ZofunikiraKugwiritsa ntchitoMalo ochapira ophatikizidwa ndi BESSndi V2B kuonetsetsa kuti nyumba yamalonda siipitirira kuchuluka kwa mphamvu zake.

3. Zofunikira Zaukadaulo: Ubwino wa MIDA

Mayendedwe a MIDA mbali zonse ziwiriMa module amphamvu a EVGwiritsani ntchito ukadaulo wa Silicon Carbide (SiC) kuti muwonetsetse kuti mphamvu ikugwira ntchito bwino kwambiri paulendo wobwerera. Izi ndizofunikira chifukwa kuchuluka kulikonse kwa kutayika panthawi yotulutsa magetsi kumadya phindu la wogwiritsa ntchito.

• Ma Voltage Range Ambiri: Imathandizira 150V mpaka 1000V, kuonetsetsa kuti ikugwirizana ndi zomangamanga zamagalimoto za 400V zomwe zilipo panopa komanso zomangamanga zamtsogolo za 800V/1000V.
• Kulankhulana: Kukhazikitsa kwathunthu kwa ISO 15118-20 stack kuti pakhale "Plug & Charge" yotetezeka komanso yogwirana chanza mbali zonse ziwiri.

4. Kuyanjana kwa Grid ndi Zomangamanga Zanzeru

Kuti ma charger a V2G akule bwino, ayenera kulumikizidwa mumakina ochapira magetsi a EV okhala ndi mphamvu ya dzuwa komanso malo osungira zinthuIzi zimathandiza malo ochajira magetsi kuti aziyang'anira kupanga magetsi m'deralo (solar), malo osungira magetsi m'deralo (BESS), ndi malo osungira magetsi m'manja (mobile storage) ngati malo amodzi opangira magetsi (VPP).

FAQ

1. Kodi pali EV iliyonse yomwe ingathe kuchita V2G?Ayi, EV iyenera kukhala ndi chochapira cha mbali zonse ziwiri (cha AC V2G) kapena chothandizira chachapira cha mbali zonse ziwiri cha DC (cha DC V2G), pamodzi ndi njira zofunika zolumikizirana.

2. Kodi ndingapeze ndalama zingati kuchokera ku V2G?Ndalama zomwe amapeza zimasiyana malinga ndi msika ndi zolimbikitsa zamagetsi, koma ogwira ntchito m'makampani a V2G omwe akugwira ntchito amatha kusunga ndalama zambiri kapena kupeza ndalama pagalimoto iliyonse pachaka.

3. Kodi V2G imawononga batire ya galimoto?Ma BMS amakono ndi ma algorithm anzeru a V2G amachepetsa kuwonongeka kwa njinga. Nthawi zambiri, ndalama zomwe zimapezedwa zimaposa kuwonongeka kwa batri.

4. Kodi kusiyana pakati pa V2G ndi V2B ndi kotani?V2G imatumiza magetsi ku gridi ya anthu onse, pomwe V2B (Galimoto yopita ku Nyumba) imagwiritsa ntchito galimotoyo kupatsa mphamvu nyumba inayake, nthawi zambiri kuti ipewe ndalama zambiri zogulira magetsi.

5. Kodi zida za MIDA zakonzeka kugwiritsa ntchito V2G?Inde, zatsopano zathuMayankho ochapira a V2Gamangidwa pa muyezo wa ISO 15118-20 ndipo ali okonzeka kugwiritsidwa ntchito pamalonda.

6. Kodi ndikufunika cholumikizira chapadera cha V2G?Zolumikizira za CCS2, NACS, ndi CHAdeMO zokhazikika zimathandiza V2G, bola ngati zida zamkati ndi mapulogalamu zili mbali zonse ziwiri.

7. Kodi mautumiki amaona bwanji V2G?Makampani ogwira ntchito m'makampani akuwona V2G ngati chida chamtengo wapatali chokhazikitsa gridi komanso njira yopewera kugwiritsa ntchito malo okwera mtengo kwambiri.
