V2H V2G V2L Kodi kugwiritsa ntchito wirirectional charger ndi chiyani?

Kodi kugwiritsa ntchito bidirectional charger ndi chiyani?
Ma charger a Bidirectional atha kugwiritsidwa ntchito pazinthu ziwiri zosiyana. Yoyamba komanso yomwe imakambidwa kwambiri ndi Vehicle-to-grid kapena V2G, yopangidwa kuti itumize kapena kutumiza mphamvu ku gridi yamagetsi pamene kufunikira kuli kwakukulu. Ngati masauzande a magalimoto okhala ndi ukadaulo wa V2G amalumikizidwa ndikuyatsidwa, izi zimatha kusintha momwe magetsi amasungidwira ndikupangidwira pamlingo waukulu. Ma EV ali ndi mabatire akulu, amphamvu, kotero kuti mphamvu zophatikizidwa zamagalimoto masauzande ambiri okhala ndi V2G zitha kukhala zazikulu. Zindikirani kuti V2X ndi mawu omwe nthawi zina amagwiritsidwa ntchito pofotokoza mitundu itatu yomwe yafotokozedwa pansipa.

Galimoto-to-grid kapena V2G - EV imatumiza mphamvu kunja kuti ithandizire gridi yamagetsi.
Galimoto yopita kunyumba kapena V2H - Mphamvu za EV zimagwiritsidwa ntchito kulimbikitsa nyumba kapena bizinesi.
Galimoto yonyamula kapena V2L * - EV itha kugwiritsidwa ntchito kupangira zida zamagetsi kapena kulipiritsa ma EV ena
* V2L sifunikira chojambulira chapawiri kuti chigwire ntchito

Kugwiritsa ntchito kwachiwiri kwa ma charger a bidirectional EV ndi kwa Vehicle-to-home kapena V2H. Monga momwe mayina amasonyezera, V2H imathandizira EV kuti igwiritsidwe ntchito ngati batire lanyumba kuti lisunge mphamvu zochulukirapo komanso mphamvu zanyumba yanu. Mwachitsanzo, makina a batire apanyumba, monga Tesla Powerwall, ali ndi mphamvu ya 13.5kWh. Mosiyana ndi izi, EV yapakati imakhala ndi mphamvu ya 65kWh, yofanana ndi ma Tesla Powerwall pafupifupi asanu. Chifukwa cha kuchuluka kwa batire, EV yodzaza mokwanira imatha kuthandizira nyumba pafupifupi masiku angapo otsatizana kapena kupitilira apo ikaphatikizidwa ndi solar yapadenga.

galimoto-to-grid - V2G
Vehicle-to-grid (V2G) ndi pamene gawo laling'ono la mphamvu ya batri ya EV yosungidwa imatumizidwa ku gridi yamagetsi ikafunika, malingana ndi dongosolo la utumiki. Kuti mutenge nawo mbali pamapulogalamu a V2G, chojambulira cha DC cha bidirectional ndi EV yogwirizana ndiyofunikira. Zoonadi, pali zolimbikitsa zachuma kuti achite izi ndipo eni eni a EV amapatsidwa ngongole kapena kuchepetsa mtengo wamagetsi. Ma EV okhala ndi V2G amathanso kupangitsa eni ake kutenga nawo gawo mu pulogalamu yamagetsi yamagetsi (VPP) kuti apititse patsogolo kukhazikika kwa gridi ndikupereka mphamvu panthawi yomwe ikufunika kwambiri. Ma EV ochepa okha omwe ali ndi V2G ndi bidirectional DC amatha kulipiritsa; Izi zikuphatikizanso mtundu waposachedwa wa Nissan Leaf (ZE1) ndi ma hybrids a Mitsubishi Outlander kapena Eclipse plug-in.

Ngakhale zadziwika, limodzi mwamavuto pakutulutsidwa kwaukadaulo wa V2G ndizovuta zowongolera komanso kusowa kwa ma protocol ndi zolumikizira zolumikizirana. Ma charger a Bidirectional, monga ma inverter a solar, amatengedwa ngati njira ina yopangira magetsi ndipo amayenera kukwaniritsa miyezo yonse yachitetezo ndi kuzimitsa ngati grid yalephereka. Pofuna kuthana ndi zovutazi, opanga magalimoto ena, monga Ford, apanga njira zosavuta zolipiritsa za AC zomwe zimangogwira ntchito ndi Ford EVs kupereka mphamvu kunyumba m'malo motumiza ku gridi. Zina, monga Nissan, zimagwiritsa ntchito ma charger ozungulira padziko lonse lapansi monga Wallbox Quasar, ofotokozedwa mwatsatanetsatane pansipa. Dziwani zambiri zaubwino waukadaulo wa V2G.
Masiku ano, ma EV ambiri ali ndi doko la CCS DC. Pakadali pano, EV yokhayo yomwe imagwiritsa ntchito doko la CCS polipira maulendo awiri ndi Ford F-150 Lightning EV yomwe yangotulutsidwa kumene. Komabe, ma EV ochulukirapo okhala ndi madoko olumikizira CCS apezeka ndi kuthekera kwa V2H ndi V2G posachedwa, pomwe VW ikulengeza magalimoto ake amagetsi a ID atha kuyitanitsa nthawi ina mu 2023.
2. Galimoto Yopita Kunyumba - V2H
Vehicle-to-home (V2H) ndi yofanana ndi V2G, koma mphamvuyi imagwiritsidwa ntchito kwanuko kulimbikitsa nyumba m'malo mongoperekedwa mu gridi yamagetsi. Izi zimathandizira kuti EV igwire ntchito ngati batire yokhazikika yapanyumba kuti ithandizire kudzidalira, makamaka ikaphatikizidwa ndi solar yapadenga. Komabe, phindu lowoneka bwino la V2H ndikutha kupereka mphamvu zosunga zobwezeretsera panthawi yakuda.

Kuti V2H igwire ntchito, pamafunika chojambulira cha EV chogwirizana ndi bidirectional ndi zida zowonjezera, kuphatikiza mita yamagetsi (CT mita) yoyikidwa pamalo olumikizira gridi yayikulu. CT mita imayang'anira kuthamanga kwa mphamvu kupita ndi kuchokera ku gridi. Dongosolo likazindikira mphamvu ya gridi yomwe nyumba yanu imagwiritsa ntchito, imawonetsa chojambulira cha bidirectional EV kuti chipereke kuchuluka kofanana, ndikuchotsa mphamvu iliyonse yotengedwa pagululi. Momwemonso, makinawo akazindikira kuti magetsi akutumizidwa kuchokera padenga ladzuwa, amapatutsa izi kuti azilipiritsa EV, zomwe ndizofanana ndi momwe ma charger anzeru a EV amagwirira ntchito. Kuti athe mphamvu zosunga zobwezeretsera pakagwa mdima kapena mwadzidzidzi, dongosolo V2H ayenera kudziwa gululi kuzimitsa ndi kuzipatula pa netiweki pogwiritsa ntchito contactor basi (kusintha). Izi zimadziwika kuti Islanding, ndipo inverter ya bidirectional kwenikweni imagwira ntchito ngati inverter yopanda gridi pogwiritsa ntchito batire ya EV. Zida zolekanitsa ma gridi zimafunikira kuti zitheke kugwira ntchito zosunga zobwezeretsera, monga ma inverters osakanizidwa omwe amagwiritsidwa ntchito pamakina osungira mabatire.
