Zophatikizika zimatha kuchokera ku ma cell asanu ndi atatu mu chida chamagetsi mpaka masauzande a ma module m'malo osungira grid.
Kodi mabatire amtundu wanji amakhala nthawi yayitali bwanji?
Zothandizira-zosanjikiza nthawi zambiri zimatha zaka 10-15 kuchuluka kwake kusanatsike ndi 80%. Ndi kasamalidwe koyenera komanso kupalasa njinga pang'ono, magulu ena amafika zaka 20. Kuwonongeka kumadalira kutentha kwa ntchito, kuchuluka kwa ndalama / kutulutsa, ndi kuya kwa kutulutsa. Mizere imayendetsedwa tsiku lililonse mpaka kuya kwa 90% kumatsika mwachangu kuposa omwe amayendetsa mpaka 50%.
Kodi mutha kusakaniza mitundu yosiyanasiyana ya batri pamndandanda?
Ayi. Kusakaniza mitundu ya batri, zaka, kapena kuchuluka kwake mugulu kumayambitsa kusalinganika komwe kumachepetsa magwiridwe antchito ndikuyika ziwopsezo zachitetezo. Mabatire onse pamndandanda akuyenera kukhala ofanana-ma chemistry, mphamvu, mphamvu yamagetsi, ndipo makamaka kuchokera mugulu lofananira lopanga. Mafakitale osiyanasiyana ali ndi mawonekedwe osiyanasiyana amagetsi komanso kukana kwamkati, zomwe zimapangitsa kuti magwiridwe antchito azikhala osatheka.
Kodi chimachitika ndi chiyani ngati batire imodzi yalephera pamndandanda?
M'kasinthidwe ka mndandanda, selo lolephera limatha kuyimitsa kuyenda kwanthawi yayitali kudzera mu chingwecho, kuchepetsa kuchuluka kwa gulu lonse. M'kasinthidwe kofananira, zingwe zina zimapitilira kugwira ntchito mocheperako. Zopanga zamakono zimagwiritsa ntchito mapangidwe amodular pomwe BMS imatha kudzipatula ma module omwe alephera. Kuchulukitsa uku kumatanthauza kuti kulephera kwa selo limodzi sikulepheretsa gulu lonse-kungochepetsa mphamvu pang'ono mpaka gawo lolakwika lisinthidwa.
Kupanga Arrays Kugwira Ntchito Pantchito Yanu
Mabatire amayendera bwino akapangidwa kuti azitsatira zofunikira zenizeni osati zamtundu uliwonse. Dzuwa lanyumba lanyumba limafunikira mawonekedwe osiyanasiyana kuposa galimoto yamagetsi kapena malo osungira grid.
Yambani pofotokoza magawo atatu: magetsi ofunikira, mphamvu yofunikira, ndi mbiri yotulutsa. Makina oyendera dzuwa a 48V amafunikira mabatire okonzedwa kuti atulutse 48V mwadzina. Ngati mukufuna 10 kWh yosungirako, gawani ndi magetsi: 10,000 Wh ÷ 48V=208 Ah mphamvu yofunikira.
Kenako, sankhani mafotokozedwe oyenera a cell. Mabatire a lithiamu wamba a 12V amabwera ndi mphamvu kuchokera pa 50Ah mpaka 200Ah. Mabatire anayi a 12V 52Ah mndandanda amapanga 48V 52Ah (2.5 kWh). Kuti mufikire 10 kWh, mufunika zingwe zinayi zofananira za mabatire anayi-16 mabatire onse mu 4s4p.
Ganizirani mitengo yotulutsa. Ngati pulogalamu yanu ikufuna mphamvu ya 5 kW pachimake, gululo liyenera kupereka 5000W ÷ 48V=104A. Chingwe chilichonse cha 4s chimapereka batire imodzi yomwe ilipo. Ngati batire iliyonse ikuyesa kutulutsa 50A mosalekeza, mumangofunika zingwe zitatu zofananira, osati zinayi. Gululi lidzakhala 4s3p ndi mabatire 12.
Kuwongolera kutentha nthawi zambiri kumatsimikizira kupambana kapena kulephera. Mabatire sagwira bwino ntchito pansi pa digirii 0 ndikuwonongeka msanga kuposa madigiri 40. Ntchito zogwirira ntchito panja zimafunikira kutenthedwa kumadera ozizira komanso kuziziritsa kotentha. Ngakhale kugwiritsa ntchito pang'onopang'ono kumapindula ndi mpanda wa insulated ndi mpweya wabwino womwe umasunga madigiri 15-25.
Yang'anirani machitidwe mosamala mukamagwira ntchito koyamba. Kutsika kwamagetsi m'masabata oyamba kumawonetsa kusagwirizana kwakupanga. Yang'anirani kusalinganika koyambirira kudzera m'malo mwa ma cell kapena kusanja bwino m'malo molola ma cell ofooka kusokoneza magwiridwe antchito.
Ma modularity a batri ndi mphamvu zawo zazikulu. Mutha kuyamba pang'ono ndikukulitsa pang'onopang'ono, ndikuwonjezera zingwe zofananira kuti muzitha kuchuluka kapena zingwe zotsatizana zamagetsi apamwamba. Kuchulukiraku kumapangitsa kuti magulu azitha kupezeka mosavuta ngakhale pamapulogalamu omwe amatha kukula pakapita nthawi.
