Ah Bisobanura Iki Ku Bateri? Amasaha ya Amp

Natakaje igiharuro c'ingene umu client yampamagaye ambaza igituma "200Ah battery bank" yabo yaheze umutobe inyuma y'amasaha 3 gusa mu gihe ibiharuro vyavuga ko bikwiye kumara 8. Inyishu ngufi? Uwo mubare wa Ah uri ku rupapuro ntusobanura ivyo abantu benshi biyumvira ko usobanura.

Ah bisobanura iki ku bateri?Ihagarariye ampere-isaha-ingero y'ingene umuyagankuba ubika muri bateri. Iyumvire nk’itangi ry’amavuta ry’ikamyo. Igitoro c'amagaloni 100-kikubwira ubushobozi, ariko ntikikubwira kure uzogenda mu vy'ukuri. Ivyo bivana n’umuzigo uriko urakurura, ahantu uri, ikirere, n’uko moteri yawe ari iyo gufata amavuta- canke iyo gufata gaze.

Amabateri na yo nyene akora gutyo nyene. Igitigiri ca 100Ah bisigura ko bateri ishobora gutanga 100 amps mu masaha imwe, canke 10 amps mu masaha cumi, canke 1 amp mu masaha ijana. Ariko "théoriquement" ni ugukora cane guterura ibintu biremerera muri iyo sentence.

Ehe ikintu gihambaye mu vy’ukuri ku muntu wese agura amabateri y’ikibanza c’ubudandaji, ubuhinga bwo gusubiza inyuma inganda, canke umugambi w’ibikorwa vy’ubuhinga: gutahura itandukaniro riri hagati y’ivyo bicapwe ku rupapuro rw’amakuru n’ivyo vyerekana mw’isi nyakuri. Ivyo ubimenye nabi, kandi uriko uriha ubushobozi utazokwigera ukoresha canke uriko uratera imbere igihe uburyo bwawe bwo gucungera amakuru buzoba buvuye hagati -ubuzimvye.

Ivyo Biharuro Ni Vyoroshe. Ukuri Siko biri.

Formule y'ishimikiro ntishobora kuba yoroshe kuruta:

Igihe co gukora=Ubushobozi bwa bateri (Ah) ÷ Ubu (A)

Ufise bateri ya 100Ah? Ukoresha umuzigo w’ama amp 10? Ivyo ni amasaha 10 y’urugendo. Vyakozwe.

Keretse... sivyo vy’ukuri. Sinigeze mbona bateri mu vy’ukuri itanga ubushobozi bwayo bwose hanze y’ibarabara. Ehe igituma iyo formule igwa mu murima:

Ikibazo c'igipimo co gusohoka

Abahinguzi ba bateri bagerageza ubushobozi mu bihe vyihariye-kenshi na kenshi ni ugusohoka buhoro buhoro, mu masaha 20 (vyitwa igipimo ca C/20). Bateri yawe ya 100Ah yaronse iyo rating mu gukura amps 5 gusa amasaha 20 agororotse.

Ariko system yawe yo gusubiza inyuma ntiyikura 5 amps. It draws 50. Canke 100. Kandi iyo ukuye current vyihuta gutyo, ntaho ushika hafi y’ubushobozi bwategekanijwe.

Ikintu c'ubushuhe

Amabateri aranka ibihe vy’ubukonje hafi nk’uko nanje ndavyanka. Ku bushuhe bukonje cane, ushobora kuronka gusa 70-75% vy’ubushobozi bwategekanijwe. Ku -20 ? Urabona kumbure igice.

Nari mfise umukiriya muri Minnesota yariko aratanga amakuru yabo yo hanze y’ubuhinga bwa none ashingiye ku bikorwa vy’icuma. Igihe ca mbere, iyo sisitemu yarananiwe. Icigwa gizimvye.

Ikinogo c'ubuhinga bwa shimi

Iyi ni yo nini, kandi niho mbona amakosa azimvye cane.

Bateri y’amabuye y’agaciro-aside y’amabuye y’agaciro 100Ah n’iy’amabuye y’agaciro y’amabuye y’agaciro 100Ah si ikintu kimwe. N’aho nyene nta hafi. Ni nk’ukugereranya itangi ry’amagaloni 100-mu modoka y’ibara ry’agahama n’igice c’ikamyo-umubare umwe, utandukanye rwose n’urugero rwo gukoresha.

Kuki Lead-Aside na Litiyumu Ah Ratings zidashobora kugereranywa ataco zitwaye

Mu mpera z’imyaka ya 1800, umunyabwenge w’Umudagi yitwa Wilhelm Peukert yarabonye ikintu kidasanzwe: uko wihuta gukura amazi muri bateri, ni ko inguvu zose uyikuramwo zigabanuka. Ivyiyumviro vyiwe biracadutera ubwoba n’ubu.

Ehe uburyo bukora: Amabateri y'aside y'amabuye y'agaciro-afise ubushobozi bwo guhangana n'ibintu vyinshi imbere. Iyo ukuruye umuriro uremereye, inguvu nyinshi ziratakara nk’ubushuhe buri muri bateri aho guha ubushobozi ibikoresho vyawe. Igiharuro ca Peukert kigereranya izo -amabateri y'amabuye y'agaciro-aside zifise amanota 1.2 gushika kuri 1.6, bisobanura ko ubushobozi butakaza cane iyo zifise umuzigo.

Amabateri ya litiyumu? Igiharuro cabo ca Peukert kiri hagati ya 1.02 na 1.05. Hafi y’aho ataco bimaze. Uronka hafi ubushobozi bwose bugereranywa utitaye ku kuntu uriko urakwega cane.

Insobanuro y’igicapo: Bateri y’acide ya lead-ifise ubushobozi bwa 100Ah itanga gusa nk’amasaha 55Ah iyo ivuye mu masaha 2 aho gutanga amasaha 20. Bateri ya litiyumu itanga 98Ah mu bihe nk’ivyo nyene. Ikete rimwe, ibikorwa bitandukanye cane.

Ariko birarushiriza kuba bibi ku bijanye n’aside y’amabuye y’agaciro-. Ntushobora kandi gukoresha ubushobozi bwose utaciye bateri.

Deep-gukuraho amabuye y'agaciro-aside bateri ubudasiba munsi y'ibice 50% vy'ubumara, kandi uzogabanya cane ubuzima bwayo. Benshi mu bakora ibintu barasaba ko uguma hejuru ya 50%-bisobanura ko bateri yawe ya "100Ah" vy'ukuri iguha ubushobozi bwo gukoresha 50Ah.

Bateri za litiyumu zikora 80-90% vy’uburebure bw’amazi asohoka mu buryo busanzwe, zimwe mbere zikora 100%. Bateri yawe ya litiyumu 100Ah itanga ubushobozi bwo gukoresha 80-90Ah.

Reka nshireko imibare nyayo kuri ivyo:

Ivyo nyene Ah igitigiri. Bateri ya litiyumu itanga hafi incuro zibiri inguvu zikoreshwa.

Ivyo turabibona biguma bigenda mu bijanye n’ugusubiramwo ivy’amatelefone n’ivy’inganda. Umugambi uherutse gukorwa wari ushimikiye ku kigo c’amatelefone co kure cane cari cizigiye banki y’acide y’amabuye y’agaciro y’amashanyarazi y’amashanyarazi y’amashanyarazi y’amashanyarazi y’amashanyarazi y’amashanyarazi y’amashanyarazi y’amashanyarazi y’amashanyarazi y’amashanyarazi 400Ah. Uwo mukoresha yarababaye kubera ko umuriro waguma uhagarara inyuma y’amasaha 3 gusa y’ubushobozi bwo gusubiza inyuma-buke cane ku masaha 6 basabwa.

Twarasubirije iyo banki nini n'ibice vy'ibikoresho vy'ubuhinga bwa 200Ah 48V LiFePO4-mu buryo bw'ubuhinga igice c'ubushobozi bwa "izina". None ivyo vyavuyemwo? Ubuhinga bushasha bwatanze amasaha arenga 5 y’igihe co gukora kidahinduka kubera ko butagira ingorane z’ugutakaza kwa Peukert mu gihe c’umuzigo uremereye w’urubuga. Umukiriya yararonse 60% vy'igihe nyaco-cy'isi kuva kuri sisitemu ipima 60% bike. Ukwo ni kwo gutandukanya hagati y’gutahura ico Ah bisobanura kuri baterimu vyiyumviro n’ivyo itanga mu bikorwa.

Ivyo ivyo bipimo vya C-ku mpapuro z'ibisobanuro bisobanura mu vy'ukuri

Iyo wimba mu mpapuro z'amakuru ya bateri, uzobona ubushobozi buri ku rutonde rw'ibipimo bitandukanye "C-." Ivyo si ugutangaza -bikubwira neza ingene umuhinguzi yagerageje uwo mubare.

C/20 bisigura ko bateri yari yacitse mu masaha 20. C/10 bisigura amasaha 10. C/5 bisigura amasaha 5.

Ico bafata: abahinguzi batandukanye bakoresha ibiciro bitandukanye vya C- ku bijanye n'imirongo yabo. Hariho amashirahamwe y’ingengo y’imari agerageza kuri C/100 (ugusohoka kw’amasaha 100) kugira ngo ashire hejuru igitigiri ca Ah. Iyo bateri ya 100Ah yageragejwe kuri C/100? Ishobora gutanga gusa 70Ah ku rugero rwa C/20 abahinguzi ba premium bakoresha.

Imbere yo kugereranya amabateri abiri yose, suzuma igipimo ca C-. Nimba batandukanye, ukugereranya nta co kumaze.

Gusuzuma ubwenge bwihuse: nimba bateri isa neza cane kugiciro-ku-Ah, suzuma igiciro ca C-bakoresha. Kenshi usanga "bargain" bateri yageragejwe mu bihe ataco bimeze nk'ivyo ukoresha.

Ah na Wh na kWh: Gutuma Ivyiyumviro Vyawe Bigororoka

Ivyo bitera abantu ubudasiba. Reka ndabisobanure.

Ah (ampere -amasaha)ikubwira ubushobozi bwo gushaja-ingene umuriro uri mu gihe kingahe.

Wh (amasaha -)ikubwira ubushobozi bw'inguvu-inguvu nyazo zikoreshwa ziharura umuriro.

Uguhinduka:Inguvu (Wh)=Ubushobozi (Ah) × Inkomezi (V)

Bateri y’amashanyarazi 12V, 100Ah ibika amashanyarazi 1.200Wh. Bateri y’amashanyarazi 48V, 100Ah ibika amashanyarazi 4.800Wh.

Incuro zine z'umuriro, incuro zine z'inguvu-naho vyose bivuga "100Ah" ku rupapuro.

Iyo uriko uragereranya amafaranga y’abaguzi batandukanye, wama uhindura Wh canke kWh. Nabonye amashirahamwe y’amasoko ategeka mu mpanuka uburyo butari bwo kubera ko bagereranya imibare ya Ah ku bibanza bitandukanye vy’amashanyarazi.

Ivyiyumviro vyihuse ku miterere isanzwe:

Ibikorwa vy’ukuri: Guhuza Ah n’ivyo ukeneye vy’ukuri

Ivyiyumviro bihagije. Reka tuganire ku bushobozi ukeneye mu vy’ukuri ku bikorwa rusangi vy’ubudandaji n’inganda.

Inguvu zo gusubiza inyuma ku mitwaro ikomeye

Inzira yo gupima ingano itangura n’igenzura ry’umuzigo wawe. Ni igiki vy’ukuri gitegerezwa kuguma gikora mu gihe umuriro uzimye, kandi kizomara igihe kingana iki?

Ehe ingene ngenda aba clients muri vyo:

Intambwe ya 1: Gutanga urutonde rw'umuzigo wose uhambaye n'igishushanyo cawo c'ubu

Urumuri rw'ivyihutirwa: 5A

Uburyo bwo gucungera umutekano: 3A

Intambwe ya 5: Zikuza ku ngano ziboneka

Asidi y'amabuye y'agaciro: uburyo bwa 300Ah

Ubuzima PO4: 200Ah uburyo

Ivyo nyene ni vyo gusaba. Ubuhinga bwa litiyumu ni buto, buraremereye, kandi akenshi burahenda cane mu kiringo cose c’ubuzima bwabwo naho nyene bugura amahera menshi imbere y’igihe.

Gushavura n'ugugabanya amafaranga y'ugusaba

Ibara ritandukanye rwose. Aha uriko urapima ubunini ushingiye ku vyo usaba ukeneye gushavura n’igihe idirisha ryawe ry’ivyo usaba ry’isonga rimara.

Niba ikigo cawe gishika ku nsonga za 500kW mu idirisha ry’amasaha 2 y’inyuma y’umuhingamo, kandi ushaka gukuraho 200kW kuri iyo nsonga:

Inguvu zikenewe: 200kW × amasaha 2=400kWh

Ku murongo wa 400V: 400.000Wh ÷ 400V=1.000Ah

Ariko kandi urakeneye gutanga ibarura ku bushobozi bw’inverter (~95%) n’uburebure bw’imipaka y’ugusohoka. Ingano y'isi nyayo yoshobora kuba 1.200-1.300Ah ku 400V.

Gupima ubunini bw'isonga ry'ugushavura bisaba kuraba kure y'ibiharuro vyoroshe vya Ah kugeza ku bushobozi burengeye -C-rate. Twaheruka gukoresha 215kWh y’amazi-cooled C&I cabinet ku kigo c’ubuhinga gihanganye n’amahera menshi y’ugusaba. Bakeneye gusohoka ningoga kugira ngo bashobore gutera umuyagankuba w’iminota 15 buri muhingamo.

Bateri y'inguvu-cell" yari gushuha cane canke igacika intege mu nguvu z'umuriro munsi y'ubwo bukomezi. Mu gupima ubunini bw’uburyo n’ibice vy’ubushobozi bwinshi-bishobora gusohora 1C, twafashije iyo nyubakwa kugabanya amafaranga y’ivyo basaba n’amadolari nka 2.800 ku kwezi. Ubuhinga bwarihevye mu myaka irenga 3.5-si kubera ko bwari bufise igiharuro ca Ah kinini kuruta ibindi vyose ku mpapuro, ariko kubera ko bwashobora gutanga ubwo bushobozi igihe ubusabe bw’uruja n’uruza bwari ku rugero rwo hejuru.

Izuba + Ububiko

Iyo ufatanya amabateri n'izuba, uba uriko uringaniza ibintu bibiri: kubika umuyagankuba uhagije wo ku murango kugira ngo upfuke imizigo yo ku mugoroba, no kugira ubushobozi buhagije bwo kwihanganira ibicu-umunsi.

Uburyo bwo kubika izuba-plus-bushobora gupima ubunini bwa banki ya bateri ku masaha 2-4 y'umuzigo usanzwe. Niba ikigo cawe gikoresha 50kW mu masaha y’umugoroba kandi ushaka amasaha 3 yo kubika:

50kW × amasaha 3=150kWh

Aha nihoIgisubizo c'inyuma ca Polinovel BESSkenshi zihuye neza-zigenewe neza na neza ubwo bwoko bw'ubudandaji bw'izuba, n'ubushobozi kuva kuri 120kWh gushika hafi 1MWh mu miterere y'ibice.

Ibendera ry'umutuku igihe usuzuma abagurisha amabateri

Inyuma y’imyaka muri iyo nganda, narateguye igikoresho co gutahura BS cizigirwa cane ku bijanye n’ibimenyetso vy’amabateri. Ehe ivyo wokwitwararika:

Ubushobozi bwageragejwe ku bipimo bitari vyo C-

Nimba umubare Ah w’umutwe wageragejwe kuri C/100 ariko ubusabe bwawe bugasohoka kuri C/5, iyo spec ntaco imaze kuri wewe. Saba amakuru y’ubushobozi ku rugero nyarwo witeze rwo gusohoka.

Ubushuhe burabura

Buri muhinguzi wemewe atangaza ubushobozi bwo gukuraho imirongo y’ubushuhe. Iyo baguhaye umubare umwe gusa ata context y’ubushuhe, hari ico bihishije.

Ivyifuzo vy'ubuzima bw'ingendo ata n'ivyo DoD ivuga

"10,000 cycles" ivuga neza cane gushika usomye inyandiko nziza cane ukabona ko iri ku 50% y'uburebure bw'amazi asohoka. Ku 80% DoD, iyo bateri nyene yoshobora kumara gusa inzinguzingu 4.000. Imisi yose ubaze: inzinguzingu ku DoD iyihe?

Nta makuru ya Peukert yerekeye aside y'amabuye y'agaciro

Niba umuhinguzi w'amabateri y'aside y'amabuye y'agaciro-atazokubwira igiharuro ca Peukert canke ngo aguhe ubushobozi ku bipimo bitandukanye vy'ugusohoka, genda. Barazi ko igitigiri cabo kigaragara nabi.

"Ibingana Ah" ibiharuro

Abahinguzi bamwebamwe-cane cane mu kibanza ca litiyumu-bakoresha ibiharuro vya "Ah bingana" bigereranya bateri yabo n'aside y'amabuye y'agaciro-. Bateri yanditsweko ngo "100Ah ingana" mu vy'ukuri yoshobora kuba ari 50Ah. Si ukubesha mu buryo bw’ubuhinga, ariko vyagenewe kugutera urujijo.

Mu laboratwari yacu y’ubuhinga, turasuzuma neza igice cose c’ingingo imbere y’uko kija mu gice. Turanka ubudasiba "bargain" cells zivuga ko zifise Ah ratings nyinshi ariko zikananirwa iyo zifise umuzigo. Nk’akarorero, twaherutse kugerageza urugero rw’ingingo y’umubiri rwavuye ku mucuruzi wo hanze rwakora neza ku 1 amp (C/100) ariko rwasenyuka rukagera kuri 65Ah igihe twakwega 50 amps (0.5C)-umuzigo usanzwe w’amamashini y’inganda.

Ni co gituma amategeko yacu yerekeye urupapuro rw'amakuru akomeye: dutanga ingero zacuubushobozi bwa BESS bw'ubudandajiishingiye ku mirongo y’amazi ikora vy’ukuri, atari ku nzira y’amazi asohoka. Iyo umuguzi atazokwereka igipimo c’ugusohoka kw’amazi ku 0.5C canke 1C, aba ariko arahisha ubushobozi nyakuri bwa bateri yabo.

Ingano y'uruzitiro-Urugero n'Ibikoresho BESS

Ku migambi y'urugero rw'ubuhinga-, ntitugivuga ivy'ibiharuro vya Ah vy'umuntu ku giti ciwe-turiko turavuga ivy'ubushobozi bwa MWh buhuriweko bushingiye ku bihumbi vy'ibice.

Arikogutahura ico Ah bisobanura kuri bateriku rugero rw'agace biracari bihambaye, kuko bigufasha gusuzuma imiterere ya sisitemu no gufata amakosa y'ibisobanuro.

Ehe ingene imibare ikora kuri sisitemu isanzwe y'ibikoresho:

Igikoresho gisanzwe c’ingingo ni 280Ah LiFePO4 ku 3.2V y’izina.

Inguvu ku gice: 280Ah × 3,2V=896Wh ≈ 0,9kWh

Ku gikoresho c'amashanyarazi 5MWh: 5.000kWh ÷ 0.9kWh=~5.556 z'amaseli zikenewe

Izo nzira zitunganijwe mu mirongo y’urutonde (kugira ngo yubake umuriro) n’imirongo ihuye (kugira ngo yubake ubushobozi). Itunganywa risanzwe rishobora kuba:

Utugingo ngengabuzima 16 mu rutonde=51.2V

Ivyigwa vyinshi mu rukurikirane=400-800V rack

Ivyuma vyinshi bihuye=ubushobozi bwa MWh bugenewe

Igihe usuzuma amajambo ya BESS, suzuma:

Urugero rw'agace -Ah n'umuhinguzi

Urutonde/imiterere y'uruhererekane

Inguvu zose ziharuwe zihuye n'ubushobozi buvugwa

Urugendo rwo gusubira inyuma-rukora neza (kenshi 85-92%)

Inguvu z'inyongera zikoreshwa (gukonjesha, BMS) zigabanya ubushobozi bwo gukoresha

Uburyo bwa BESS bwa Polinovelkuva kuri 3.85MWh gushika kuri 5MWh+ ku gikoresho, hakoreshejwe utugingo ngengabuzima twa LiFePO4 cane cane kubera ubuzima bwazo bwiza cane n’ugushikama kw’ubushuhe mu bikoresho vy’uburemere bwinshi-.

Umurongo wo hasi ku bipimo vya Bateri Ah

Raba,Ah bisobanura iki kuri baterisi ikintu kigoye mu vyiyumviro. Ni ingero y’ubushobozi bwo gucapura. Gukubita n’umuriro kugira ngo ubone inguvu. Gabanya n'umuzigo w'ubu kugira ngo ugereranye igihe co gukora.

Ivyo biva ku bintu vyose vy’ukuri-vy’isi bishobora gusenyura ubwo bushobozi bw’ivyiyumviro: ingaruka z’urugero rw’ibisohoka, ugugabanya ubushuhe, uburebure -bw’-imipaka y’ibisohoka, n’itandukaniro ry’ubuhinga.

Aba clients nkorana na bo birinda amakosa azimvye ni bo:

Igihe cose uhindure kWh ikoreshwa, ntuhindure izina Ah
