Ah bisobanura iki kuri Bateri? Amp Isaha

Nabuze kubara inshuro umukiriya yampamagaye mubaza impamvu "banki ya bateri 200Ah" yabuze umutobe nyuma yamasaha 3 gusa iyo mibare ivuga ko igomba kumara 8. Igisubizo kigufi? Iyo Ah nimero kuri label ntabwo isobanura icyo abantu benshi batekereza ko bivuze.

Ah bisobanura iki kuri bateri?Igereranya ampere - isaha - igipimo cyerekana umubare w'amashanyarazi abika bateri. Bitekerezeho nk'ikigega cya lisansi mu gikamyo. Ikigega cya 100 - gallon kikubwira ubushobozi, ariko ntigikubwira intera uzatwara. Ibyo biterwa numutwaro ukurura, terrain, ikirere, nimba moteri yawe ari lisansi - sipper cyangwa gaze-guzzler.

Batteri ikora kimwe. Igipimo cya 100Ah bivuze ko bateri ishobora gutanga amps 100 kumasaha imwe, cyangwa amps 10 kumasaha icumi, cyangwa amp 1 kumasaha ijana. Ariko "mubyukuri" ni ugukora ibintu byinshi biremereye muri iyo nteruro.

Dore icyangombwa mubyukuri umuntu wese ugura bateri kubucuruzi bwubucuruzi, sisitemu yo kugarura inganda, cyangwa umushinga wingirakamaro: gusobanukirwa itandukaniro riri hagati yibyanditswe kuri datasheet nibigaragara kwisi. Fata iki kibi, kandi urimo kwishyura ubushobozi utazigera ukoresha cyangwa gutombora mugihe sisitemu yo kugarura ibintu ikuye hagati -.

Imibare iroroshye. Ukuri Ntabwo.

Inzira y'ibanze ntishobora koroha:

Igihe cyogukora {{0} Cap Ubushobozi bwa Bateri (Ah) ÷ Umutwaro uriho (A)

Kubona bateri 100Ah? Gukoresha umutwaro wa amp 10? Nibyo amasaha 10 yo gukora. Byakozwe.

Usibye ... ntabwo mubyukuri. Ntabwo nigeze mbona bateri itanga ubushobozi bwayo bwuzuye hanze ya laboratoire. Dore impamvu iyo formula itandukana mumurima:

Ikibazo cyo Gusohora Ikibazo

Abakora bateri bapima ubushobozi mubihe byihariye - mubisanzwe isohoka gahoro, yoroheje mumasaha 20 (bita igipimo cya C / 20). Bateri yawe 100Ah yabonye urwo rutonde ushushanya amps 5 gusa mumasaha 20 ugororotse.

Ariko sisitemu yo gusubira inyuma ntabwo ishushanya amps 5. Ikurura 50. Cyangwa 100. Kandi iyo ukwega umuyoboro wihuse, ntaho ugera hafi yubushobozi bwagenwe.

Ubushyuhe

Batteri yanga ibihe bikonje nkanjye. Ubukonje bukonje, ushobora kubona 70-75% yubushobozi bwagenwe. Kuri dogere -20? Urimo kureba ahari kimwe cya kabiri.

Nari mfite umukiriya muri Minnesota werekana ko bagurisha itumanaho hanze bakurikije imikorere yizuba. Ubukonje bwa mbere, sisitemu yananiwe. Isomo rihenze.

Icyuho cya Chimie

Iri ni rinini, kandi niho mbona amakosa ahenze cyane.

Amashanyarazi 100Ah - bateri ya acide na batiri ya 100Ah lithium ntabwo arikintu kimwe. Ntanubwo ari hafi. Ninkaho kugereranya 100 - gallon muri sedan hamwe na kamyo ya kimwe cya kabiri, umubare ukoreshwa rwose.

Impamvu Kurongora - Acide na Litiyumu Ah Ibipimo ntibishobora kugereranwa muburyo butaziguye

Kera mu mpera za 1800, umuhanga w’umudage witwa Wilhelm Peukert yasanze ikintu kitameze neza: uko wihuta ukuramo bateri, imbaraga nke zose urayivamo. Imibare ye iracyaduhiga muri iki gihe.

Dore verisiyo ifatika: Bateri ya aside - aside irwanya imbere. Iyo ukurura umuyaga uremereye, imbaraga nyinshi ziba impfabusa nkubushyuhe imbere muri bateri aho guha ibikoresho ibikoresho byawe. Ikimenyetso cya Peukert kigereranya iyi - kuyobora - bateri ya acide mubisanzwe ifite amanota 1.2 kugeza kuri 1.6, bivuze gutakaza imbaraga zikomeye munsi yumutwaro.

Batteri ya Litiyumu? Peukert yabo yerekanwe ni 1.02 kugeza 1.05. Hafi ya ntarengwa. Urabona hafi yubushobozi bwuzuye utitaye kuburyo ukurura.

Imbonerahamwe ibisobanuro: Amashanyarazi - acide ya acide yagereranijwe kuri 100Ah itanga nka 55Ah gusa iyo isohotse mumasaha 2 aho kuba 20. Bateri ya lithium itanga 98Ah mubihe bimwe. Ikirango kimwe, imikorere itandukanye cyane.

Ariko birushaho kuba bibi kuri aside - aside. Ntushobora kandi gukoresha ubushobozi bwuzuye utishe bateri.

Byimbitse - gusohora amashanyarazi - acide buri gihe munsi ya 50% yumuriro, kandi uzagabanya cyane igihe cyayo. Ababikora benshi basaba kuguma hejuru ya 50% - bivuze ko bateri yawe "100Ah" iguha 50Ah yubushobozi bukoreshwa.

Batteri ya Litiyumu ikoresha ubujyakuzimu bwa 80-90% buri gihe, bimwe ndetse 100%. Bateri yawe ya 100Ah ya lithium itanga 80-90Ah yubushobozi bukoreshwa.

Reka nshyireho imibare nyayo kuriyi:

Igipimo kimwe Ah. Batiri ya lithium itanga hafi kabiri ingufu zikoreshwa.

Turabona iyi ikinamico idahwema gutumanaho no kuvugurura inganda. Umushinga uherutse urimo sitasiyo ya tereviziyo ya kure yari ishingiye kuri 400Ah iremereye - banki ya aside. Umukoresha yarababajwe nuko voltage sag yakomeje gukurura umuriro - guhagarika amashanyarazi nyuma yamasaha 3 gusa yo kugarura imbaraga - mugihe gito cyamasaha 6 basabwa.

Twasimbuye iyo banki nini hamwe na 200Ah 48V LiFePO4 moderi ya rack - tekiniki kimwe cya kabiri cyubushobozi bwa "nameplate". Igisubizo? Sisitemu nshya yatanze amasaha arenga 5 yigihe cyogukora kuko itigeze ihura nigihombo cya Peukert munsi yumutwaro uremereye wurubuga. Umukiriya yabonye neza hejuru ya 60% nyayo - igihe cyisi kuva muri sisitemu ipima 60% munsi. Itandukanirogusobanukirwa icyo Ah bivuze kuri baterimubitekerezo bitandukanye nibyo itanga mubikorwa.

Icyo C - Ibipimo kumpapuro zihariye bivuze

Iyo ucukuye muri datasheets ya batiri, uzabona ubushobozi bwanditse kurutonde "C -." Ntabwo ari marketing marketing - irakubwira neza uko uwabikoze yagerageje iyo mibare.

C / 20 bivuze ko bateri yasohotse mumasaha 20. C / 10 bisobanura amasaha 10. C / 5 bisobanura amasaha 5.

Gufata: abahinguzi batandukanye bakoresha C - ibiciro bitandukanye kumutwe wabo. Ibiranga ingengo yimari imwe yipimisha kuri C / 100 (gusohora amasaha 100) kugirango yongere umubare wabo Ah. Iyo bateri 100Ah yageragejwe kuri C / 100? Irashobora gutanga 70Ah gusa ku gipimo cya C / 20 abakora premium bakoresha.

Mbere yo kugereranya bateri ebyiri zose, genzura igipimo C -. Niba batandukanye, kugereranya ntacyo bivuze.

Kugenzura vuba vuba: niba bateri isa neza cyane kuba impamo kubiciro - kuri - Ah, reba igipimo C - bakoresha. Usanga kenshi "bateri" bateri yageragejwe mubihe ntakintu kimeze nka progaramu yawe.

Ah na Wh na kWh: Kubona Units yawe neza

Ibi bigenda abantu buri gihe. Reka mbisobanure.

Ah (ampere - amasaha)ikubwira ubushobozi bwo kwishura - ingahe mugihe kingana iki.

Ninde (watt - amasaha)ikubwira ubushobozi bwingufu - ingufu zishobora gukoreshwa zibarirwa kuri voltage.

Guhinduka:Ingufu (Wh)=Ubushobozi (Ah) × Umuvuduko (V)

Batiri ya 12V, 100Ah ibika 1,200Wh. Bateri ya 48V, 100Ah ibika 4.800Wh.

Inshuro enye za voltage, inshuro enye ingufu - nubwo bombi bavuga "100Ah" kuri label.

Iyo ugereranije amagambo yavuzwe nabacuruzi batandukanye, burigihe uhindure kuri Wh cyangwa kWh. Nabonye amatsinda yamasoko ateganya kubwimpanuka sisitemu itariyo kuko bagereranije nimero ya Ah kurubuga rwa voltage zitandukanye.

Ibisobanuro byihuse kubisanzwe bisanzwe:

Porogaramu nyayo: Guhuza Ah kubyo Ukeneye Mubyukuri

Igitekerezo gihagije. Reka tuvuge kubyerekeranye nubushobozi ukeneye mubikorwa rusange byubucuruzi ninganda.

Imbaraga zimanikwa kumitwaro ikomeye

Ingano yo gutangira itangirana no kugenzura imitwaro yawe. Niki rwose kigomba kuguma kwiruka mugihe cyo guhagarara, kandi kugeza ryari?

Dore uko ngenda abakiriya banyuzemo:

Intambwe ya 1: Andika buri mutwaro uremereye nigishushanyo cyacyo

Kogosha cyane no gusaba kugabanya amafaranga

Kubara bitandukanye. Hano uringaniye ukurikije spike isabwa ugomba kwiyogoshesha hamwe nigihe cyamadirishya asabwa.

Niba ikigo cyawe gikubise impinga ya 500kW mugihe cy'amasaha 2 nyuma ya saa sita, ukaba ushaka kogosha 200kW kuri iyo mpinga:

Ingufu zikenewe: 200kW × amasaha 2=400 kWt

Kuri sisitemu ya 400V: 400.000Wh ÷ 400V=1, 000Ah

Ariko ugomba kandi kubara kubikorwa bya inverter (~ 95%) hamwe nubujyakuzimu bwimipaka. Nukuri - ubunini bwisi bushobora kuba 1,200-1,300Ah kuri 400V.

Kuringaniza imisatsi yogosha bisaba kureba hejuru ya Ah byoroshye kurwego rwo hejuru - C - imikorere yikigereranyo. Muminsi ishize twohereje 215kWh y'amazi - akonje ya kabili ya C&I kugirango ikore uruganda rukora ibirego bikabije. Bakeneye gusohora vuba kugirango basibanganye ingufu z'iminota 15 buri gicamunsi.

Batiyeri "ingufu - selile" yaba yarashyushye cyane cyangwa igabanuka muri voltage munsi yubukomezi. Mugupima sisitemu hamwe ningirabuzimafatizo - zifite ubushobozi bwo gukomeza gusohora 1C, twafashije ikigo kugabanya amafaranga basabwa hafi $ 2.800 buri kwezi. Sisitemu yishyuye ubwayo mu myaka irenga 3.5 gusa - sibyo kuko yari ifite amanota menshi Ah ku mpapuro, ariko kubera ko yashoboraga gutanga izo mbaraga mugihe icyifuzo cya gride kigeze.

Imirasire y'izuba

Mugihe uhuza bateri nizuba, uba uringaniza ibintu bibiri: kubika ibisekuru bihagije kumanywa kugirango utwikire imitwaro ya nimugoroba, kandi ufite ubushobozi buhagije bwo kwihanganira ibicu -.

Ubusanzwe izuba ryubucuruzi - wongeyeho - sisitemu yo kubika irashobora gupima banki ya batiri kumasaha 2-4 yumutwaro ugereranije. Niba ikigo cyawe gikoresha 50kW mugihe cyamasaha ya nimugoroba ukaba ushaka amasaha 3 yo kubika:

50kW × amasaha 3=150 kWt

Aha nihoPolinovel yo hanze yinama y'abaminisitiri BESS ibisubizoakenshi bihuye neza - byashizweho muburyo bunoze bwo guhuza izuba ryubucuruzi, hamwe nubushobozi kuva 120kWh kugeza kuri 1MWh muburyo bwa modular.

Ibendera ritukura mugihe dusuzuma abatanga bateri

Nyuma yimyaka muriyi nganda, nateje imbere icyuma cyiza cya BS cyerekana ibikoresho bya batiri. Dore ibyo ugomba kureba:

Ubushobozi bwageragejwe kubiciro C - bidashoboka

Niba umutwe Ah umubare wageragejwe kuri C / 100 ariko gusaba kwawe gusohora kuri C / 5, iyo ngingo ntacyo imaze kuri wewe. Baza amakuru yubushobozi ku gipimo cyawe giteganijwe gusohoka.

Kubura ibisobanuro by'ubushyuhe

Buri ruganda rwemewe rutangaza ubushobozi bwo kugabanya ubushyuhe. Niba baguha numero imwe gusa idafite ubushyuhe, hari icyo bahishe.

Ubuzima bwikizamini busaba nta DoD imiterere

"10,000 cycle" yumvikana neza kugeza usomye neza icapiro ugasanga biri kuri 50% byubujyakuzimu. Kuri 80% DoD, bateri imwe irashobora kumara 4000 gusa. Buri gihe ubaze: inzinguzingo kuri DoD?

Nta makuru ya Peukert yo kuyobora - aside

Niba uruganda - uruganda rukora bateri ntirukubwira icyerekezo cya Peukert cyangwa ngo rutange umurongo wubushobozi ku bipimo bitandukanye bisohoka, genda. Bazi ko umubare wabo usa nabi.

Ibipimo "Bihwanye na Ah"

Bamwe mubakora - cyane cyane mumwanya wa lithium - bakoresha "ihwanye na Ah" igereranya bateri yabo kuyobora - aside. Batare yanditseho "100Ah ihwanye" irashobora kuba 50Ah. Ntabwo ari ukubeshya mubuhanga, ariko yagenewe kugutesha umutwe.

Muri laboratoire yacu yubuhanga, twemeza byimazeyo buri selile mbere yuko ijya muri module. Turahora twanga "kugurirana" selile zisaba Ah amanota menshi ariko bikananirana munsi yumutwaro. Kurugero, duherutse kugerageza icyitegererezo cyakagari kiva mubitanga hanze cyakoze neza kuri amp 1 (C / 100) ariko kigwa kuri 65Ah mugihe twakururaga amps 50 (0.5C) - umutwaro usanzwe wimashini zinganda.

Niyo mpamvu politiki yimibare yacu itajenjetse: tugereranya ibyacuubucuruzi BESS ubushobozibishingiye kubikorwa bifatika bifatika, ntabwo bisohora ibintu. Niba utanga isoko atakwereka umurongo wo gusohora kuri 0.5C cyangwa 1C, bahisha imikorere yukuri ya bateri yabo.

Ingano ya Grid - Umunzani kandi urimo BESS

Kubikorwa byingirakamaro - imishinga minini, ntabwo tuvuga ibyiciro bya Ah kugiti cyawe - turavuga ubushobozi bwa MWh bwuzuye bwubatswe kuva selile ibihumbi.

Arikogusobanukirwa icyo Ah bivuze kuri baterikurwego rwakagari biracyafite akamaro, kuko bigufasha gusuzuma igishushanyo mbonera no gufata amakosa yibisobanuro.

Dore uko imibare ikora kuri sisitemu isanzwe igizwe:

Imiterere ya selile isanzwe ni 280Ah LiFePO4 selile prismatic kuri 3.2V nominal.

Ingufu kuri selile: 280Ah × 3.2V=896 Wh ≈ 0.9kWh

Kubikoresho bya 5MWh: 5,000kWh ÷ 0.9kWh=~ 5,556 selile

Utugingo ngengabuzima dutondekanye mu ruhererekane rw'imirongo (kubaka voltage) n'imirongo ibangikanye (kubaka ubushobozi). Ibikoresho bisanzwe bishobora kuba:

Ingirabuzimafatizo 16 zikurikirana=51.2 V module

Module nyinshi murukurikirane=400-800 V rack

Ibice byinshi muburyo bubangikanye=intego ya MWh

Mugihe usuzumye amagambo ya BESS yabitswe, genzura:

Akagari - urwego Ah urwego nuwabikoze

Urukurikirane / iboneza

Ingufu zose zabazwe zihuye zisaba ubushobozi
