Ma Battery Energy Storage Systems (BESS) akusintha momwe timagwiritsira ntchito mphamvu, kupereka zochulukaof zopindulitsa kuphatikiza kugwiritsa ntchito mphamvu mwanzeru, kuchepetsa mtengo, kulimba mtima, kusamala zinthu, komanso kugwiritsa ntchito bwino chilengedwe.
BESS imabwera mosiyanasiyana, kuyambira mayunitsi apanyumba apanyumba mpaka makina akuluakulu othandizira othandizira ndi mafakitale padziko lonse lapansi.Machitidwewa, komabe, amasiyana malinga ndi electrochemistry kapena teknoloji ya batri yomwe amagwiritsa ntchito.M'nkhaniyi, tifufuza mitundu yoyambirira ya mabatire a BESS ndi mwayi womwe amapereka wopezera mayankho osungira mphamvu.
Mabatire a Lithium-Ion (Li-Ion).
Malinga ndi lipoti la 2020 la US Energy Information Administration (EIA), oposa 90% a Battery Energy Storage Systems akuluakulu ku USA adadalira mabatire a lithiamu-ion.Ziwerengero zapadziko lonse zikugwirizana ndi izi.Mtundu wa batri womwe ungathe kuwonjezeredwanso umapezeka paliponse m'magalimoto amagetsi, zamagetsi ogula, ndi zida zonyamula katundu monga mafoni a m'manja, ma laputopu, mapiritsi, ndi makamera.Mabatire a lithiamu-ion amaphatikiza ma chemistry osiyanasiyana, kuphatikiza lithiamu cobalt oxide, lithiamu manganese oxide, lithiamu iron phosphate, ndi lithiamu nickel manganese cobalt oxide (NMC), pakati pa ena.
Ubwino wa mabatire a Li-ion ndi ochuluka, kuwapanga kukhala ukadaulo wotsogola pakusungirako mphamvu.Mabatirewa ndi opepuka, ophatikizika, amadzitamandira kuti ali ndi mphamvu zambiri komanso kachulukidwe kamphamvu, amafunikira chisamaliro chochepa, ndipo amawonetsa moyo wautali.Kuphatikiza apo, amalipira mwachangu komanso amakhala ndi ziwongola dzanja zochepa.Komabe, zovuta zawo zimaphatikizapo kukwera mtengo, kuyaka, komanso kukhudzidwa ndi kutentha kwambiri, kuchulukitsitsa, komanso kutulutsa mopitilira muyeso.
Mabatire a Lead-Acid (PbA).
Mabatire a lead-acid akuyimira imodzi mwamakina akale kwambiri komanso otsika mtengo kwambiri a batire omwe alipo.Amapeza kugwiritsidwa ntchito kwambiri pamagalimoto, ntchito zamafakitale, ndi makina osungira magetsi.Zodziwika bwino, mabatirewa amatha kubwezeredwanso kwambiri ndipo amagwira ntchito bwino m'malo okwera komanso otsika.Mabatire a valve-regulated lead-acid (VRLA), osinthika amakono, amaposa omwe adalipo kale ndi moyo wautali, kuchuluka kwa mphamvu, komanso kukonza kosavuta.Komabe, kuyitanitsa pang'onopang'ono, kulemera kwakukulu, komanso kutsika kwamphamvu kwamphamvu ndizolepheretsa zazikulu zaukadaulowu.
Mabatire a Nickel-Cadmium (Ni-Cd).
Mabatire a Ni-Cd anali otchuka mumagetsi otha kuvala mpaka kubwera kwa mabatire a Li-ion.Mabatirewa amapereka kusinthasintha ndi masinthidwe ambiri, kukwanitsa, kuyenda mosavuta ndi kusungirako, komanso kupirira kutentha kotsika.Komabe, amatsalira kumbuyo kwa omwe akupikisana nawo pakuchulukira kwa mphamvu, kutsika kwamadzimadzi, komanso kubwezeretsedwanso.Mabatire a nickel-metal hydride (Ni-MH), kugawana nickel oxide hydroxide (NiO(OH))) ngati chigawo chimodzi ndi ukadaulo wa Ni-Cd, amapereka zinthu zapamwamba monga kuchuluka kwa mphamvu komanso kuchuluka kwa mphamvu.
Mabatire a Sodium-Sulfur (Na-S).
Mabatire a sodium ndi sulfure amagwiritsa ntchito mchere wosungunula, zomwe zimapangitsa kuti akhale luso lotsika mtengo.Mabatirewa amapambana mu mphamvu ndi kuchuluka kwa mphamvu, moyo wautali, komanso kugwira ntchito mokhazikika pansi pazovuta kwambiri.Komabe, kugwiritsa ntchito kwawo kumakhala kochepa chifukwa cha kufunikira kwa kutentha kwakukulu (osachepera 300 ℃) komanso kutengeka ndi dzimbiri.Sodium, yomwe ndi gawo lofunikira kwambiri, imabweretsa nkhawa zachitetezo chifukwa imatha kuyaka komanso kuphulika.Ngakhale zovuta izi, mabatire a sodium-sulfure amatsimikizira kuti ndi abwino kusungirako mphamvu zoyima zophatikizidwa ndi magwero amagetsi ongowonjezwdwa.
Mabatire Oyenda
Zosiyana ndi mabatire wamba rechargeable kuti kusunga mphamvu mu zipangizo olimba elekitirodi, otaya mabatire nyumba mphamvu mu madzi electrolyte njira.Mtundu wofala kwambiri ndi batire ya vanadium redox (VRB), yokhala ndi mitundu ina kuphatikiza zinc-bromine, zinc-iron, ndi iron-chromium chemistries.Mabatire oyenda amapereka phindu lapadera, kuphatikiza moyo wautali (mpaka zaka 30), kuchulukirachulukira, kuyankha mwachangu, komanso chiwopsezo chamoto chochepa chifukwa cha ma electrolyte osayaka.Makhalidwewa apangitsa kuti mabatire oyenda akhale gawo lalikulu pamsika pamakina osungira magetsi pa gridi ndi kunja kwa gridi, makamaka pakugwiritsa ntchito kwakukulu.
Ndi matekinoloje a batri awa, mawonekedwe amagetsi akusintha, ndikupereka mayankho osiyanasiyana kuti akwaniritse zosowa zosiyanasiyana m'mafakitale ndi magawo.Pamene ukadaulo ukupitilirabe kusinthika, gawo la Battery Energy Storage Systems likhala lofunikira kwambiri pakukonza tsogolo lathu lamphamvu.
