Makhalidwe Aukadaulo a Battery Yosungira Mphamvu Zanyumba

Kukwera kwamitengo yamagetsi ku Europe sikunangowonjezera kukula kwa msika wapadenga wa PV, komanso kwachititsa kukula kwakukulu kwamakina osungira mphamvu za batri kunyumba.Lipoti laMawonekedwe a Msika waku Europe Wosungira Battery Yokhalamo2022-2026lofalitsidwa ndi SolarPower Europe (SPE) apeza kuti mu 2021, pafupifupi 250,000 mabatire osungira magetsi adayikidwa kuti athandizire magetsi aku Europe okhala ndi dzuwa.Msika waku Europe wosungira batire yanyumba mu 2021 unafika 2.3GWh.Pakati pazimenezi, Germany ili ndi gawo lalikulu kwambiri la msika, lowerengera 59%, ndipo mphamvu yatsopano yosungiramo mphamvu ndi 1.3GWh ndi chiwerengero cha kukula kwa 81%.

Zikuyembekezeka kuti kumapeto kwa chaka cha 2026, mphamvu zonse zosungiramo mphamvu zosungiramo nyumba zidzawonjezeka ndi 300% mpaka 32.2GWh, ndipo chiwerengero cha mabanja omwe ali ndi makina osungira mphamvu a PV chidzafika pa 3.9 miliyoni.

M'nyumba yosungirako mphamvu zamagetsi, batire yosungira mphamvu ndi imodzi mwazinthu zofunika kwambiri.Pakalipano, mabatire a lithiamu-ion ali ndi malo ofunikira kwambiri pamsika wa mabatire osungira mphamvu kunyumba chifukwa cha makhalidwe awo ofunika monga kukula kwake kochepa, kulemera kwake komanso moyo wautali wautumiki.

Mu dongosolo lamakono la batri la lithiamu-ion, lagawidwa mu batri ya lithiamu ya ternary, lithiamu manganate batire ndi lithiamu chitsulo phosphate batire malinga ndi zinthu zabwino electrode.Poganizira zachitetezo, moyo wozungulira ndi magawo ena ogwirira ntchito, mabatire a lithiamu iron phosphate ndi omwe ali ambiri m'mabatire osungira mphamvu kunyumba.Kwa mabatire a lithiamu iron phosphate m'nyumba, zinthu zazikuluzikulu zikuphatikiza izi:

1. good chitetezo ntchito.Pakugwiritsa ntchito batire yosungira mphamvu kunyumba, chitetezo ndichofunika kwambiri.Poyerekeza ndi ternary lithiamu batire, lifiyamu chitsulo mankwala batire oveteredwa voteji ndi otsika, 3.2V yekha, pamene zinthu matenthedwe kuwola othawa kutentha ndi apamwamba kuposa 200 ℃ wa ternary lithiamu batire, kotero izo zimasonyeza bwino chitetezo ntchito.Pa nthawi yomweyo, ndi zina chitukuko cha batire paketi kapangidwe luso ndi luso batire kasamalidwe, pali zambiri zinachitikira ndi luso ntchito luso mmene kusamalira bwino lithiamu chitsulo mankwala mabatire, amene kulimbikitsa ntchito lonse la lithiamu chitsulo mankwala mabatire mu munda wa nyumba yosungirako mphamvu.
2. anjira yabwino kuposa mabatire a lead-acid.Kwa nthawi yayitali m'mbuyomu, mabatire osungira mphamvu ndi mphamvu zosunga zobwezeretsera anali makamaka mabatire a asidi a lead, ndipo makina owongolera ofananira adapangidwa potengera kuchuluka kwa ma voliyumu a mabatire a lead-acid ndipo adakhala oyenera padziko lonse lapansi komanso apanyumba. miyezo,.M'makina onse a batri a lithiamu-ion, mabatire a lithiamu iron phosphate pamndandanda amafanana bwino ndi batire ya lead-acid yotulutsa mphamvu.Mwachitsanzo, voteji ntchito 12.8V lithiamu chitsulo mankwala batire ndi za 10V kuti 14.6V, pamene ogwira ntchito voteji 12V kutsogolera asidi batire ali kwenikweni pakati 10.8V ndi 14.4V.
3. Moyo wautali wautumiki.Pakadali pano, pakati pa mabatire onse okhazikika okhazikika, mabatire a lithiamu iron phosphate ali ndi moyo wautali kwambiri wozungulira.Kuchokera pamayendedwe amoyo wa cell, batire ya acid-acid imakhala pafupifupi nthawi 300, batire ya ternary lithiamu imatha kufika nthawi 1000, pomwe batire ya lithiamu iron phosphate imatha kupitilira nthawi 2000.Ndi kukweza kwa kupanga, kukhwima kwa ukadaulo wa lithiamu replenishment, etc., mabwalo amoyo a lithiamu iron phosphate mabatire amatha kufikira nthawi zopitilira 5,000 kapena 10,000.Pazinthu za batri zosungiramo mphamvu zanyumba, ngakhale kuchuluka kwa mikombero kudzaperekedwa kumlingo wina (omwe uliponso m'machitidwe ena a batri) pakuwonjezera kuchuluka kwa ma cell amtundu uliwonse kudzera mu kulumikizana motsatizana (nthawi zina mofananira), zolephera zamitundu yambiri. ndi mabatire amitundu yambiri adzakonzedwanso kudzera mu kukhathamiritsa kwaukadaulo wapawiri, kapangidwe kazinthu, ukadaulo wochotsa kutentha ndi ukadaulo wowongolera batri pamlingo waukulu kuti upititse patsogolo moyo wautumiki.
