Bateri ya lithium yumuriro mwinshini bateri yo kubika ingufu zimenya imbaraga nyinshi za DC zisohoka muri sisitemu muguhuza bateri nyinshi murukurikirane. Hamwe n’ingufu zigenda zikenerwa n’ingufu zishobora kuvugururwa, hamwe n’abantu bibanda ku buryo bwiza kandi bunoze bwo guhindura imirasire y’izuba, bateri za lithium zifite ingufu nyinshi zabaye kimwe mu bisubizo by’ingufu zizwi cyane ku isoko.
Muri 2024, uburyo bwa sisitemu yo kubika amazu y’umuvuduko mwinshi biragaragara, inganda zitunganya ingufu za batiri zibika ingufu hamwe n’ibirango byatangije bateri zitandukanye z’amashanyarazi akomoka ku mirasire y’izuba, izi bateri ntabwo zifite ubushobozi gusa, ubuzima bwizunguruka n’ibindi bice bya intambwe igaragara, ariko no mumutekano no gucunga ubwenge bikomeje gutera imbere. Muri iyi ngingo, tuzaguha incamake ya bateri zimwe na zimwe zidasanzwe za litiro ya lithium muri 2024, kugirango tugufashe guhitamo nezabateri yo murugosisitemu yo kubika ibikwiranye nibyo ukeneye.
Igipimo cya 1: Ubushobozi bwa Bateri
Ubushobozi bwa bateri yingirakamaro bivuga imbaraga ushobora kwishyuza muri bateri kugirango ukoreshwe nyuma murugo. Mugereranije 2024 tugereranya na bateri ya lithium nini cyane, sisitemu yo kubika itanga ubushobozi bwingirakamaro cyane ni bateri ya Sungrow SBH hamwe na 40kWh, ikurikirwa hafi naUmukino wa BSLBATT HVSbateri hamwe na 37.28kWh.
Igipimo cya 2: Imbaraga
Imbaraga ni umubare w'amashanyarazi bateri yawe Li-ion ishobora gutanga mugihe runaka; bipimirwa muri kilowatts (kilowati). Kumenya imbaraga, urashobora kumenya umubare wibikoresho byamashanyarazi ushobora gucomeka icyarimwe. Mugereranya na batiri ya 2024 ya lithium-ion ya batiri, BSLBATT MatchBox HVS yongeye kwigaragaza kuri 18.64 kW, irenga inshuro ebyiri ugereranije na Huawei Luna 2000, kandi BSLBATT MatchBox HVS irashobora kugera ku mbaraga zingana na 40 kW kuri 5s .
Igipimo cya 3: Kuzenguruka-Urugendo
Urugendo-rugendo rugereranya ikigereranyo kiri hagati yingufu ukeneye kwishyuza bateri ningufu ziboneka mugihe urekuye. Yitwa rero "urugendo-rugendo (kuri bateri) no kugaruka (kuva muri bateri) gukora neza". Itandukaniro riri hagati yibi bice byombi biterwa nuko burigihe habaho gutakaza ingufu muguhindura imbaraga kuva DC kuri AC naho ubundi; igihombo gike, niko bateri Li-ion ikora neza. Mugereranije 2024 tugereranya na bateri ya lithium yumuriro mwinshi, BSLBATT MatchBOX na BYD HVS yashyizwe kumwanya wa mbere hamwe na 96% ikora neza, ikurikirwa na Fox ESS ESC na Sungrow SPH kuri 95%.
Igipimo cya 4: Ubucucike bw'ingufu
Muri rusange, byoroheje bateri n'umwanya muto ifata, nibyiza, mugihe ugumana ubushobozi bumwe. Nyamara, bateri nyinshi zifite ingufu nyinshi za LiPoPO4 zigabanijwemo modul zifite ubunini nuburemere byoroshye gukoreshwa nabantu babiri; cyangwa rimwe na rimwe ndetse n'umuntu umwe.
Hano rero turagereranya cyane cyane ubwinshi bwingufu za buri kirango cya batiri ya lithium yumuriro mwinshi, ubwinshi bwingufu za batiri bivuga ubushobozi bwa bateri yo kubika ingufu (zizwi kandi nkingufu zihariye), arirwo kigereranyo cyingufu zose zibitswe muri bateri kugeza mubwinshi bwayo, ni ukuvuga, Wh / kg, yerekana ubunini bwingufu zishobora gutangwa kuri buri gice cya misa ya batiri.Inzira yo kubara: ubwinshi bwingufu (wh / Kg) = (ubushobozi * voltage) / misa = (Ah * V) / kg.
Ubucucike bwingufu bukoreshwa nkibipimo byingenzi byo gupima imikorere ya bateri. Muri rusange, ingufu za batiyeri nyinshi za lithium-voltage zishobora kubika ingufu nyinshi munsi yuburemere cyangwa ubunini bumwe, bityo bigatanga umwanya muremure wo gukora cyangwa intera kubikoresho. Binyuze mu kubara no kugereranya, twasanze Sungrow SBH ifite ingufu zidasanzwe zingana na 106Wh / kg, ikurikirwa na BSLBATT MacthBox HVS, nayo ifite ingufu zingana na 100.25Wh / kg.
Igipimo cya 5: Ubunini
Ubunini bwa sisitemu yo kubika ingufu ziragufasha kongera ubushobozi bwa bateri yawe ya Li-ion hamwe na module nshya nta kibazo kibangamiye iyo ingufu zawe ziyongereye. Kubwibyo, ni ngombwa kumenya ubushobozi sisitemu yo kubika ishobora kwaguka mugihe kizaza.
Mugereranije na bateri ya lithium yumuriro mwinshi mumwaka wa 2024, BSLBATT MatchBox HVS itanga impinduka nyinshi mubijyanye nubushobozi buke, bugera kuri 191.4 kWh, ikurikirwa na Sungrow SBH ifite ubushobozi buke bwa 160kWh.
Ibi, bitewe nuko turimo gutekereza kuri bateri zishobora guhuzwa na inverter imwe. Nyamara, ni ngombwa kumenya ko abakora bateri benshi bemerera inverter nyinshi gushyirwaho muburyo bubangikanye, bityo bikagura ubushobozi bwububiko bwa sisitemu yo kubika ingufu.
Igipimo cya 6: Gucana inyuma na Off-grid Porogaramu
Mu bihe by’ingufu zidahungabana n’iterabwoba ry’umuriro w’isi yose, abantu benshi kandi bifuza ko ibikoresho byabo byabasha guhangana n’ibintu bitunguranye. Kubwibyo, kugira porogaramu nkibintu byihutirwa bisohoka cyangwa gusubira inyuma, cyangwa ubushobozi bwo gukora off-grid mugihe habaye umuriro w'amashanyarazi, nibintu byingenzi cyane.
Mugereranya yacu 2024 ya bateri ya lithium yumuriro mwinshi, byose bifite ibisubizo byihutirwa cyangwa byongeye kugaruka, kandi biranashoboye gushyigikira imikorere ya gride ihujwe cyangwa itari gride.
Igipimo cya 7: Urwego rwo Kurinda
Abakora sisitemu yo kubika ingufu berekana ibicuruzwa byabo mubizamini bitandukanye kugirango berekane uburinzi bwabo kubintu bitandukanye bidukikije.
Kurugero, muri 2023 tugereranya na bateri ya lithium nini cyane, eshatu (BYD, Sungrow, na LG) zifite urwego rwo kurinda IP55, naho BSLBATT ifite urwego rwo kurinda IP54; ibi bivuze ko, nubwo bitarimo amazi, umukungugu ntushobora kubangamira imikorere yimikorere kandi ikanarinda amazi kumuvuduko runaka; ibi bibemerera gushyirwaho imbere munzu cyangwa muri garage cyangwa isuka.
Batare igaragara muri iki gipimo ni Huawei Luna 2000, ifite igipimo cyo kurinda IP66, ku buryo itabangamira umukungugu n'indege zikomeye.
Igipimo cya 8: Garanti
Garanti nuburyo bwo gukora kugirango yerekane ko yizeye ibicuruzwa byayo, kandi irashobora kuduha ibimenyetso bijyanye nubwiza bwayo. Ni muri urwo rwego, usibye imyaka ya garanti, ni ngombwa kumenya uburyo bateri izakora neza nyuma yiyo myaka.
Mugereranije 2024 tugereranya na bateri ya lithium yumuriro mwinshi, moderi zose zitanga garanti yimyaka 10. Ariko, LG ESS Flex, ihagarare mubindi, utange 70% imikorere nyuma yimyaka 10; 10% kurenza abo bahanganye.
Ku rundi ruhande, Fox ESS na Sungrow, ntibarasohora indangagaciro za EOL ku bicuruzwa byabo.

Ibibazo kuri Batteri Yumuvuduko mwinshi
Bateri ya lithium nini cyane?
Sisitemu ya batiri yumuriro mwinshi mubisanzwe ifite voltage irenga 100V kandi irashobora guhuzwa murukurikirane kugirango yongere imbaraga nubushobozi. Kugeza ubu, ingufu ntarengwa za batiri za litiro nini zikoreshwa mu kubika ingufu zo guturamo ntizirenza 800 V. Batteri nini ya voltage isanzwe igenzurwa binyuze muburyo bwa shebuja-mugaragu hamwe nagasanduku kihariye ko kugenzura.
Ni izihe nyungu za batiri ya lithium nini cyane?
Ku ruhande rumwe, sisitemu yo kubika ingufu nyinshi murugo ugereranije na voltage nkeya itekanye, ihamye, sisitemu ikora neza. Hybrid inverter circuit topology munsi ya sisitemu yo hejuru ya voltage iroroshe, igabanya ubunini nuburemere, ikanagabanya igipimo cyo gutsindwa.
Ku rundi ruhande, iyo ukoresheje bateri zifite ubushobozi bumwe, amashanyarazi ya batiri ya sisitemu yo kubika ingufu nyinshi zifite ingufu ziri hasi, ibyo bikaba bitera guhungabana gake kuri sisitemu kandi bikagabanya igihombo cyingufu bitewe nubushyuhe bwatewe nubushyuhe bwinshi.
Batteri ya lithium nini cyane ifite umutekano?
Batteri ya lithium nini cyane ikoreshwa mububiko bwingufu zo guturamo mubusanzwe iba ifite sisitemu yo gucunga neza bateri (BMS) ikurikirana ubushyuhe, voltage numuyoboro wa batiri kugirango barebe ko bateri ikora mumipaka itekanye. Nubwo bateri ya lithium yahoze ihangayikishijwe numutekano muminsi yambere kubera ibibazo byo guhunga ubushyuhe, bateri yumuriro mwinshi wa lithium uyumunsi itezimbere cyane umutekano wa sisitemu mukongera ingufu za voltage no kugabanya amashanyarazi.
Nigute nahitamo bateri ikwiye ya batiri ya lithium kuri njye?
Mugihe uhisemo bateri ya lithium yumuriro mwinshi, hagomba gutekerezwa ibintu bikurikira: sisitemu ya voltage ibisabwa, ibisabwa mubushobozi, kwihanganira ingufu zamashanyarazi, imikorere yumutekano no kumenyekana. Ni ngombwa cyane cyane guhitamo ubwoko bwa bateri bukwiye nibisobanuro ukurikije ibikenewe bya porogaramu yihariye.
Ni ikihe giciro cya bateri ya lithium nini cyane?
Amashanyarazi akomoka ku mirasire y'izuba azaba menshi cyane mu giciro kirenze izisanzwe zikoreshwa mu zuba zikoresha ingufu z'amashanyarazi akomoka ku mirasire y'izuba bitewe n'ibisabwa cyane kugira ngo ingirabuzimafatizo zihamye hamwe n'ubushobozi bwo gucunga BMS, urwego rw'ikoranabuhanga ruri hejuru cyane, ndetse no kuba sisitemu ikoresha ibice byinshi.
