Ni gute wohitamwo bateri nziza y’ingendo y’imbere?

Nzobabwira ukuri. Inyuma y’imyaka indwi nshaka amabateri yo gukoresha mu bubiko, gukoresha izuba be n’ibinyabiziga vy’amato, nararonse ivyiyumviro bikomeye ku bijanye n’ibikora n’ibidakora. Iyi si inzira y’ukugereranya itagira aho ibogamiye. Niba uriko urakora ibikorwa vy'imisi myinshi canke ukora mu bidukikije bigenzurwa n'ubushuhe, ngiye kukubwira ko litiyumu iron phosphate hafi y'igihe cose ari inyishu ibereye, kandi nzokwereka imibare kugira ngo ubigaragaze.

 

Ariko kandi narize ko "lithium ni nziza" ari ngirakamaro nk'ukuvuga ngo "imodoka zizimvye ni nziza." Ikibazo nyaco ni nimba igiciro c’imbere gifise insiguro ku bikorwa vyawe, kandi ivyo bivana n’ibintu benshi mu bagurisha batazobaza.

 

Reka ndababwire ingene mu vy’ukuri nsuzuma ingingo z’amabateri ubu, maze gukora amakosa menshi azimvye mu ntango z’akazi kanje.

Ivyo Nta n'umwe akubwira ku "Deep Cycle" nk'Iciciro

Ehe ikintu canbabaje imyaka myinshi: ijambo "deep cycle" rirakubitwa ku mabateri afise ubushobozi butandukanye cane. Igikoresho c'amadolari 150 c'amazi y'amabuye y'agaciro-"ingendo y'acide" kivuye mu iduka rinini-y'amasandugu n'igikoresho c'amadolari 900 c'amabuye y'agaciro citwa LiFePO4 vyose bifise ico kimenyetso, ariko kimwe kizomara inzinguzingu 300 ikindi kizomara 4,000+.

Ico kimenyetso kikubwira ko bateri yakozwe kugira ngo isubire gusohoka aho gutangura moteri. Nivyo. Ntaco ivuga ku:

• Ni gute mu vy’ukuri ushobora kuyisohora ataco yononekaye (50% ku aside nyinshi z’amabuye y’agaciro-, 80-100% ku litiyumu)
• Ni kangahe ivyo ushobora kubikora imbere y’uko ubushobozi bumanuka munsi y’ingero z’ingirakamaro
• Ivyo bishika iyo ubushuhe bugabanutse bushika munsi y'ubukonje
• Nimba ikirego c'"ukwitaho-ubuntu" bisigura ko ata kwitaho canke gusa kwitaho bike kurusha utugingo ngengabuzima twarengewe n'amazi

Nabonye amashirahamwe y'abaguzi agura ashingiye ku masaha y'amp- gusa, hanyuma nkibaza igituma amabateri yabo "225Ah" atanga igihe gito co gukora kurusha amabateri ya "100Ah" ya litiyumu basubiriye. Inyishu ni yoroshe: iyo bateri ya 225Ah lead-acid ishobora gutanga gusa ata nkomanzi nk’112Ah imbere y’uko utangura kuyihonya. Litiyumu 100Ah iguha ubushobozi bwo gukoresha 80-100Ah. Ivy’imibare ntibibesha.

Ingingo y'ubuhinga bwa shimi

Ivyo guhitamwo bine nyamukuru. Nzobabwira ivyo mu vy’ukuri niyumvira kuri kimwe cose.

Asidi y'amabuye y'agaciro -

Aracari n’ikibanza, ariko ico kibanza kiriko kiragabanuka. Niba ufise abakozi b'ivy'ugusanasana bazosuzuma vy'ukuri urugero rw'amazi buri ndwi zibiri (atari "igihe bibuka"), icumba c'amabateri kigenzurwa n'ubushuhe-, n'ibikorwa vy'umusi umwe-, amaseli yuzuye amazi arashobora gukora. Igiciro ca mbere ni gito vy’ukuri, ni nk’amadolari 110-185 ku kWh.

Ico cica amabateri yuzuye amazi mu bikorwa vyinshi: nta n’umwe ayabungabunga neza. Ivyo bihimba vy’umubiri bikeneye kuba amazi 65%, aside sulfurique 35% ku buremere. Uko amazi agenda arahinduka umwuka mu gihe co gucagura, aside iraduga maze igatuma amasahani yononeka. Nabonye amabateri azimvye apfa mu mezi 18 kubera ko kuyabungabunga vyaciye bifatwa nk’ivy’agaciro mu bihe vy’ibikorwa vyinshi.

Uwundi mwicanyi ni ubushuhe. Ku 0℃, witege ko 30-50% y’ubushobozi buzotakaza. Mu bikorwa vy’ifiriji? Nimwibagire.

AGM n'Igikoresho (VRLA)

Ivyo mfata vy’ukuri: ivyo ni ubuhinga bwo gusenyera ku mugozi umwe. Batorera umuti ingorane yo kwitaho (bipfutse, nta mazi yongereweko akenewe) ariko ntibatanga ubuzima bw’ingendo butera imbere bushingira intahe igiciro cabo ca 2x ku giciro c’umwuzure. Uriko uriha vyinshi kugira ngo wirinde ingorane zo kwitaho, ivyo bikaba bibereye, ariko ubuhinga bw’acid bw’amabuye y’agaciro -buca buguha uburenganzira bwo gukora inzinguzingu 500-1.000 ku AGM kumbure 1.000-2.000 ku Gel.

AGM igura vyihuta kuruta ivy’umwuzure, hafi 5x vyihuta mu bikorwa bimwe bimwe. Nimba guhindura vuba ari ngirakamaro kandi udashobora kuja muri litiyumu, AGM irafise insiguro. Gel ifata neza gusohoka kure cane ariko itwara amahera menshi kandi isaba amaparametere y’ugushaja neza.

Ku bikorwa vyo mu nzu aho abakozi bo gusanasana batizigirwa kandi ingengo y’imari itazoshika kuri litiyumu, AGM irashobora kwikingira. Ariko nimba ndiko ndavuga direct: uzosubiriza izo bateri incuro 2-3 imbere y’uko pack ya litium ikenera gusubirwamwo.

Icuma ca litiyumu (LiFePO4)

Aha niho nshika ku bikorwa vyinshi vy’ubudandaji, kandi ng’iki igituma.

Igitigiri c’ubuzima bw’ingendo si ivy’ubudandaji. Utugingo ngengabuzima twa LFP twiza dutanga vy’ukuri inzinguzingu 2.000-6.000 ku burebure bw’ibisohoka 80%. Nakurikiranye amabateri mu bubiko bw'imirongo myinshi-yatera inzinguzingu 4.000 ataco yononekaye. Gerageza ivyo n’aside y’amabuye y’agaciro uzoba uri ku nkuru yawe ya gatatu canke ya kane.

Uburemere burahambaye kuruta uko abantu biyumvira. Igipapuro ca litiyumu gipima 25-40% vy’ubushobozi bungana n’ubw’aside y’amabuye y’agaciro. Mu bikoresho vy’amatelefone ngendanwa (ivy’amazi, imodoka, ibikoresho vy’amaboko), ukwo kuzigama uburemere ni uguhindura. Mu bikorwa bihagaze, bisigura gushiramwo vyoroshe kandi n’umuzigo mutoyi w’imibumbe.

Ivyiza vyo gushaja birarushirizaho uko igihe kigenda kirarenga. Litiyumu ikora 95-98% y'uruziga-ubushobozi bw'urugendo ugereranije na 75-80% ku bijanye n'aside y'amabuye y'agaciro. Ku muzigo w’amagare w’amaguru 10kWh ku musi, ivyo ni nk’amashanyarazi makeyi akoreshwa ku musi 2kWh. Mu myaka itanu y’ibikorwa, kuzigama inguvu gusa birashobora gutanga igice kinini c’igiciro c’intango.

Ariko ni Litiyumu iyihe? Aha Niho Bica Bigorana

Kuvuga ngo "ndashaka litiyumu" ni nk'ukuvuga ngo "ndashaka imodoka." Hariho amahitamwo afise insiguro muri urwo rwego.

Ivy’ubuhinga bw’ingingo ngenderwako birahambaye.LFP (lithium iron phosphate) ni yo ikoreshwa cane mu bucuruzi no mu nganda kubera imvo nziza: ni yo nzira y’ubuhinga bwa litiyumu itekanye kuruta izindi zose, ifata neza iyo ikoreshejwe nabi, kandi itanga ubuzima budasanzwe. NMC (nickel manganese cobalt) itanga ingufu nyinshi ariko izana n’ingorane zo guhunga ubushuhe bituma bigorana kwishingira mu bibanza bimwe bimwe vy’ubudandaji. LTO (lithium titanate) ishobora guhangana n’ubushuhe bukaze cane ariko igura 2-3x kuruta.

Ku bikorwa vyinshi vya B2B, LFP ni inyishu ibereye. Igihano c’uburemere bw’inguvu n’ivyo NMC ntaco bimaze iyo utariko uragerageza gushiramwo amabateri muri telefone ngendanwa.

Ubushobozi bw'ingingo bugira ico bukoze ku kwizigirwa.Iryo shirahamwe ryashizeho cane cane ama 280Ah prismatic cells ava ku bahinga nka EVE na CATL. EVE LF280K yacitse ikintu c’umubumbe w’ishingiro. Utugingo ngengabuzima tunini bisigura ko hariho uturongo duke two gufatanya mu gipapuro, ivyo bisigura ko hariho uburyo buke bwo kunanirwa. Ariko utugingo ngengabuzima tunini na two dusaba inyubakwa za BMS zagenewe guhuza ubushobozi bwinshi-.

Utugingo ngengabuzima dutoduto (100Ah n'inyuma) dukora neza ku bikorwa vy'ububasha buke-. Ntureke umuntu akubwire ko kinini ari co cama ari ciza, ariko ku mapaki y’ubudandaji ari hejuru ya 5kWh, 280Ah standard irafise insiguro.

Guhitamwo BMS bitandukanya amapaki meza n’amabi.Aho niho mbona uguhinduka kw’uburyo bwinshi kw’isoko.

Gushiramwo uburinganire ataco ukora birahenda cane. Ikora mu gukura amaraso arenze urugero ava mu ngingo ziri hejuru nk’ubushuhe. Ihane ku nsoro zihuye neza-tuva mw'ihinguriro, ariko ntizishobora gutorera umuti ubusumbasumbane butera imbere uko igihe kigenda kirarenga.

Guringaniza bikora bitwara amahera menshi ariko bisubira gusangira umuriro hagati y’ingingo. JK BMS n’uburinganire bukora 2A yacitse umugambi w’ishingiro mu kwubaka kw’umwuga kubera imvo: iragura ubuzima bw’amapaki n’ibice 15-25% mu bihe vy’ukuri aho ingingo zishobora gutera imbere ata kabuza mu bushobozi butandukanye.

Niba uriko ugura ipaki yubatswe imbere, ubaze nimba BMS ikoresha uburinganire bukora canke butakora. Iyo uwugurisha atazi canke atazokwishura, iyo ni ibendera ry’umutuku.

Ubwubatsi bw’umuriro buragenda buja kuri 48V.Ku bikorwa vy’ubudandaji biri hejuru ya 5kW, ubuhinga bwa 48V buriko buraba ubusanzwe. Fizike ni yoroshe: gutera kabiri umuriro ku nguvu zidahinduka bigabanya igice c’umuriro, ivyo bikaba bisobanura ko umuriro uba mutoyi, ubushuhe buke, kandi n’ugutakaza kw’ihuriro kugabanywa. Niba uriko urahingura ikintu gishasha co gushiramwo aho gusubirira amabateri asanzweho, zirikana nimba 48V ifise insiguro ku nguvu ukeneye.

Ikibazo c’Amahera: Litiyumu Yishura Ryari?

Nashize hamwe imibare mu vy’ukuri ihambaye ku ngingo z’amasoko. Ivyo si ivy’ivyiyumviro, bishingiye ku nyandiko z’ugushirwaho n’ubushakashatsi bw’inganda.

Igereranyo ry'igiciro cose c'imyaka 10

48V 100Ah uburyo, gukoresha ibikoresho, gukoresha imirongo myinshi

Igihe co guca mu nzira gica hagati y’umwaka wa 3 n’uwa 5, bivanye n’ingene ikoreshwa rikomeye. Mu bikorwa vy'ubukazi vy'imirongo myinshi-, litiyumu iramenagurika mbere ningoga. Mu bikorwa vy'umuco-ivy'umusi umwe-, umubare w'ibihembo urakura kandi ushobora kutaba uw'agaciro.

Isesengura ry’inganda ryakozwe na Enexer ryabonye mbere n’itandukaniro rikomeye cane mu gukoresha amagare akomeza: $1,131 yose hamwe y’imyaka 10-igiciro ca LiFePO4 n’amadolari 4,445 ku mafaranga y’amabuye y’agaciro. Ivyo ni 75% vy’igiciro c’ubuzima bwose naho 3-4x ishoramari ry’imbere ry’imbere ry’amahera ryinshi.

Ivyishurwa biratandukanye cane bivanye n’ubwoko bw’ibisabwa.

Amakuru yashizwe hamwe avuye mu bushakashatsi bwa Raymond Corporation n’ivyigwa vy’inganda.

Ivyo ni ivy’ugukoresha n’ubukazi. Igitigiri canyu kizoba gitandukanye. Ariko iyo nzira irafata: iyo uriko urakoresha amabateri cane, litiyumu irishura ningoga kuruta uko benshi mu barongoye amasoko biteze.

Imitego y'Ibisobanuro Nize Kwirinda

Maze guturika incuro nkeyi, ubu ndazi neza ibibazo nokwibaza igihe nsuzuma abaguha ibintu.

Ivyiyumviro vy’ubuzima bw’ingendo nta co bimaze ata vyo gupima.Iyo umuguzi avuze ngo "12.000 cycles," ubwo nyene ubaze:

• Ni ku burebure bungana iki bw’ugusohoka? Igerageza kuri 50% DoD ritanga 2-3x igitigiri c’ingendo kiruta 80% DoD.
• Ni ku rugero rungana iki rwo kwishura/gusohora? Igerageza rya 0.5C ritanga ibisubizo bitandukanye cane n’igerageza rya 1C.
• Kugeza ku rugero rungana iki rw’ubushobozi? "Iherezo ry'ubuzima" ku 70% y'ubushobozi busigaye n'80% bihindura umubare na 40%+.
• Ni ku bushuhe ubuhe? 25℃laboratwari ivyerekeye ntivyerekana ukuntu isi nyakuri-ikoreshwa.

Ehe akarorero nyako: EVE LF280K cells zigereranywa n’ingendo 6.000 ku 1C/1C gushika ku 80% y’ubushobozi bwo kugumya. Igicuruzwa gihanganye kivuga ko "12,000 cycles" ariko kigeragejwe ku 0.5C/0.5C gushika ku 70% y'ukugumya mu vy'ukuri ntaco kiruta, naho umubare munini w'umutwe. Bariko barapima ibintu bitandukanye.

Itegeko ry’ugusohora 0.5C ubudasiba.Utugingo ngengabuzima twinshi twa LFP dufise igipimo c’ugusohoka ubudasiba ku 0.5C. Ivyo bisigura ko 100Ah cell ikwiye gutanga 50A gusa ubudasiba, atari 100A canke 200A peak ratings uzobona ku bisobanuro vya BMS.

Nabonye uku kudahuza gutuma umuntu ananirwa mbere y’igihe incuro nyinshi. Ikoreshwa rikura 80A ubudasiba kuri bateri ya "100Ah". BMS ivuga ko ishobora gufata 150A peak. Ariko rero, izo nsoro ziriko zirashirwako umubabaro birenze urugero rwazo rudahengeshanya, ubuzima bw’ingendo burasenyuka, kandi umuntu wese ashira urubanza ku buryo bwa bateri aho gushingira intahe ikosa ry’ibisobanuro.

Iyo umuzigo wawe urenze 0.5C ukomeza, ukeneye ama cells y’ubushobozi bwinshi canke ipaki igenewe canecane umuriro ukomeza.

Gukura kw’ikirangamisi bishika mbere no ku ruhande.Utugingo ngengabuzima twa LFP dutakaza ubushobozi bwavyo hafi 2,3% ku mwaka bivuye ku gukura kw’ikirangamisi gusa, bitandukanye n’ugutwara amagare. Bateri yicaye mu bubiko bw’umucuruzi amezi 18 iramaze gusenyuka 3-4% imbere y’uko uyishiramwo.

Suzuma amatariki y’uguhingura amabateri yinjira. Irinde ibintu vyamaze igihe kirekire bicaye.

Ibendera ry'umutuku igihe usuzuma abaguzi

Nateguye urutonde rw'ibintu vyo mu mutwe bishingiye ku ngorane nahuye na zo:

 Igitigiri c’amashanyarazi kiri munsi ya 0.2C ni ikintu giteye amakenga.

Iyo bateri ya 300Ah ivuga ko 50A (0.16C) yoshobora gushaja, hari ikintu kitagenda neza. Canke BMS ni nto canke izo cellules ntizishobora gukorana n’ibipimo bisanzwe vy’amacharge. LFP y’uburyo yemera 0.5C charge ata ngorane.

Ubuzima bw’ingendo buvuga ko buri hejuru y’ibihumbi 10 ata buryo burambuye.

Ubuhinga bwa none bw’ingingo ngenderwako ntibushobora gushika kuri ivyo biharuro mu gihe c’ibigeragezo vy’ukuri. Iyo umuntu avuze inzinguzingu 15.000 canke 20.000, aba ariko arakoresha ibipimo vy’igerageza bitari vyo canke ariko arahingura ibintu vy’ukuri.

Ivyumba vyuzuyemwo ikidodo bifise garanti bivaho iyo bifunguwe.

Ivyo bibuza gusuzuma no gutorera umuti ingorane. Abaguzi bashimikiye ku buhinga-bakoresha amahuzu y'amabara (ashobora gukoreshwa) kandi bagatanga uburyo bwo gukoresha BMS kugira ngo bamenye indwara. Nimba badashaka ko uraba imbere, ubaze igituma.

Nta makuru y’abahinguzi b’ingingo ngenderwako.

EVA, CATL, Hitiyumu ni amasoko yemewe. Nimba umuguzi atazotangaza aho utugingo ngengabuzima tuva, birashoboka ko bakoresha utugingo ngengabuzima tw'icigwa-B canke utugingo ngengabuzima twanse. Ibiganiro vy’abahinga (cane cane DIY Solar Forum na Marine How To) vyanditse ibibazo vyinshi vy’uburyo n’inkomoko y’ingingo zitamenyekanye.

Uburinzi bw’ubushuhe buravugwa ariko ntibwagenzuwe.

Saba inyandiko z'ubushuhe buke-igerageza ry'uguca. Nasuzumye amabateri y’ingengo y’imari aho igikoresho co gupima ubushuhe cariho ku rubaho rw’umurongo ariko nticari gifatanye n’ubuhinga bwo kurinda.

Ivyerekana uburyo bibereye kwishurwa: BMS y’uburinganire ikora, amakuru y’uguhuza utugingo ngengabuzima yanditswe (uguhinduka kw’ubushobozi kuri munsi ya 2% mu gice cose), raporo z’igerageza zasohowe zifise uburyo, n’amajambo y’igarantiya yerekana ubushobozi bwo kugumya.
