Uburyo bwo gucunga amabateri ni iki?

A uburyo bwo gucunga baterini umugenzuzi w’ubuhinga bwa none agenzura kandi akakingira amabateri ashobora gusubirwamwo, kenshi na kenshi ni amabateri ya litiyumu-ion canke LiFePO4 akozwe mu bihimba vyinshi bikurikirana kandi bihuye. Ipima ivyo akagingo ngengabuzima kamwe kamwe kariko karakora, igaharura ingene iyo paki yose yigenza, kandi ikagira ico ikoze iyo hari ikintu kigenda kiva hanze y’imipaka y’umutekano.

BMS si co kimwe n’urubaho rworoshe rwo gukingira (rimwe na rimwe rwitwa PCM, canke Module y’Uruzitiro rwo Gukingira). Igipande c'uburinzi gikora ku bibazo bikeyi vy'amakosa nk'ugushaja birenze urugero, gusohoka birenze -, n'uguca mu nzira ngufi. BMS nyayo irakora ivyo vyose, kandi iraringaniza ingingo, igereranya uko umuriro uri n’ingene ubuzima bumeze, igacungera ubushuhe, kandi akenshi ivugana n’ibindi bihimba vyo muri sisitemu biciye kuri CAN, RS485, UART canke Bluetooth. Itandukaniro rirahambaye kuko isoko rivanga ayo majambo abiri mu mwidegemvyo, kandi amabarabara menshi y'"BMS" atari make ni amabarabara y'uburinzi yiyoberanije.

Imbere mu kintu cose co kubika inguvu, BMS ni kimwe mu bintu vyinshi vyubaka. Niba ushaka kubona ingene yicara iruhande y’ibice, PCS, EMS, n’ibikoresho vy’ubushuhe, ugusenyuka kwacu kw’Ibice umunani vy'ingenzi vy'ububiko bw'inguvu za baterini umugenzi mwiza wo gusoma.

Uko BMS ikora mu vy'ukuri

BMS yose ikoresha intambwe zine- imwe, incuro ibihumbi ku segonda.

Ubwenge.Igikoresho co gupima umuriro ku gice cose, igikoresho co gutahura umuriro (shunt canke Hall{0}}effect) ku nzira nyamukuru y’umuriro, n’ibikoresho vy’ubushuhe vya NTC ku bibanza vy’ingenzi bigaburira amakuru atagiramwo ivyiza muri BMS.

Harura.Igikoresho gipima gihindura izo ngero mu mibare ikomokako: uko umuriro uri, uko ubuzima buri, ububasha buriho, ukudahukana kw’ingingo ngenderwako, ubushuhe buringaniye.

Gufata ingingo.Porogaramu y’ubuhinga igereranya vyose n’ibipimo vy’umutekano n’amategeko y’ugukoresha.

Igikogwa.Iyo bikenewe, BMS irafungura MOSFETs canke contactors kugira ngo igabanye umuriro. Bishobora kandi gutuma umurongo w’uburinganire ukora, bisaba igikoresho co gucapura ngo kigabanye, canke kigatera ibendera ry’ikosa kuri sisitemu y’umushitsi.

Uwo murongo w’ibisubizo wugarijwe ni wo utandukanya ubuhinga bwa bateri bucungiwe n’ibateri ifise igice c’uburinzi gifatanye hejuru.
 

Imikorere nyamukuru ya sisitemu yo gucunga bateri

Ivyiyumviro bitandukanye vya BMS bishimika ku bikorwa bitandukanye. Uburyo bwo gucunga neza amabateri burakora vyinshi canke vyose muri ibi bikurikira.

Ububiko-Urwego rwo Gukurikirana

BMS iguma isoma umuriro w’agace kose kari mu murongo w’urutonde, umuriro winjira n’uwusohoka mu gipapuro, n’ubushuhe buri ahantu hamwe canke henshi. Kugaragara kw'urugero rw'agace-ni co gituma ingingo z'urugero rwa pack-zishobora kwizigirwa. Gupima ku rugero rw'amapaki bihisha neza ubwoko bw'uguhungabana kw'utugingo ngengabuzima tumwe -bitera ukunanirwa.

Uburinganire bw'utugingo ngengabuzima

Mu nzira iyo ari yo yose y'utugingo ngengabuzima twinshi, utugingo ngengabuzima turakura mu buryo butandukanye gato. Hatariho uburinganire, igice gifise intege nke kuruta ibindi vyose kirabanza gutera urugero rwaco rwo hejuru rw’umuriro mu gihe co gucapura, ivyo bikaba bituma BMS ihagarika gucapura igice cose maze igasiga ubushobozi bukoreshwa buhagaze.

Uburyo bubiri ni bwo buganzwa.Gushiramwo uburinganireiturira inguvu zirenga urugero zivuye mu ngingo zo hejuru biciye ku ntungamubiri ntoyi zirwanya. Biroroshe, birahendutse, kandi bihagije ku bikoresho vyinshi vy'abaguzi n'ivy'inganda.Gushiramwo uburinganireijana inguvu mu bihimba vyo hejuru ikaja mu bihimba vyo hasi biciye mu bihimba vy’umubiri, mu bihimba vy’umubiri, canke mu bihindura DC-DC. Ni vyiza cane kandi bikagarukana ubushobozi bwo gukoreshwa, ariko vyongera igiciro n’ugusobanuka. Ugushiramwo uburinganire bukora bikunda gutanga inyungu mu mapaki manini (ugukurura EV, ububiko bw’uruzitiro-) aho isaha yose ya kilowatt-ihambaye.

SOC, SOH, na SOF Igereranyo

Ivyiza bitatu vya Leta bisa ariko bisobanura ibintu bitandukanye.

• Igihugu c'ububasha (SOC): ingene ipaki yuzuye ubu, igaragazwa nk’ijanisha. Itwara urutonde canke ikimenyetso c'igihe co gukora umukoresha abona.
• Igihugu c'ubuzima (SOH): ni ubushobozi bungana iki busigaye bugereranywa n'ibara-rishasha. Ipaki iri ku 80% SOH yatakaje 20% vy’ubushobozi bwayo bwa mbere.
• Igihugu c'Ibikorwa (SOF): nimba iyo pack ishobora gutanga ubushobozi busabwa ubu nyene, bivanye n’ubu SOC, SOH, n’ubushuhe.

Ivyuma bihendutse biratanga raporo SOC. Ivyiza kuruta ibindi bikurikirana SOH. Ivyuma vy’agaciro bitanga raporo ya SOF, ivyo ni vyo ushaka mu vy’ukuri iyo ibikorwa vy’ukwizigirwa biri ku murongo. Kugira ngo ubone intangamarara y’ingene utugingo ngengabuzima turonka ubushobozi no kubutakaza mu buzima bwabwo bwose,Ingingo ya Kaminuza ya Bateri BU-808ni umutungo mwiza w'ururimi rusanzwe-.

Uburinzi

BMS ikomeye irinda gukoreshwa cane, gusohoka cane-, gusohoka birenze urugero (mu nzira zompi), umurongo muto, n’ubushuhe bwinshi canke buke. Igitigiri cose gikwiye kuba gishobora guhindurwa, kandi igihe co gusubiza gihambaye nk’uko igitigiri ubwaco gihambaye. Inyishu y’umurongo mugufi-isanzwe iri hagati y’amasegonda 100–500; ikintu cose kiri mu rutonde rwa milisegonda kirateba cane ku bikorwa vy'ubu.

Ubuyobozi bw'ubushuhe

Ku mapaki akonjejwe ataco akora, BMS iragabanya canke igaca iyo ubushuhe bugenda burazimangana. Ku mapaki akonjejwe cane itegeka ama ventilateur, amapompo canke ibikoresho bishushanya kugumiza utugingo ngengabuzima imbere mw’idirisha ryavyo rikora. Inyungu nyinshi za litiyumu-ion zica zishaja neza hagati ya degre nka 0–45 zigaca zisohoka ku rugero rwagutse, ariko zinezerwa cane mu rwego rwa degre 15–35; ubuzima bw’ingendo buragwa ku mpande zompi. Ku bijanye n’imipaka yihariye, igitabu cacu kuubushuhe bwa bateri ya litiyumuiravuga ingene mu vy’ukuri gushaja, gukuraho no kubika bisa mu bikorwa. Ku ruhande rw’ibikoresho,guhitamwo hagati y'umuyaga n'amaziihingura ingene BMS ifise igikorwa gikomeye mu bijanye n’ubushuhe.

Guhanahana amakuru

Benshi mu ba BMS bo muri iki gihe bavugana n’isi yo hanze. CAN bus ni yo isanzwe ku modoka no ku bikoresho vy’inganda, RS485 ni yo iganzwa mu kubika inguvu zihagaze, UART canke I2C ni yo isanzwe mu bikoresho bitobito vy’abaguzi, na Bluetooth irarushiriza gukoreshwa mu ma e-bike n’inguvu zitwara abantu. Mu buryo buhagaze BMS na yo nyene irahuza n'urugero rwo hejuru-uburyo bwo gucunga inguvu (EMS), rijejwe ingingo zo kohereza, amafaranga, n’ibimenyetso vy’uruzitiro. Ivyo bibiri kenshi biratera urujijo ariko bica ku bice bitandukanye.

Gushiramwo amakuru no gupima

Hejuru-iherezo rya BMSs ry'inyandiko y'amakosa, ibara ry'ingendo, n'ivya kera vy'amateka. Ico gitabu kiraba ikintu c’agaciro kanini mu gupima amapaki yagarutse, mu kwemeza ivyerekeye garanti, no mu gutuma igicuruzwa gisubirwamwo gikurikira kigenda neza. Mu gikorwa cacu bwite ca RMA, igitabu ca BMS ni co kintu ca mbere dusoma; ipaki itagira amateka akoreshwa ni ipaki udashobora kugwanira.

Ubwoko nyamukuru bw'ubwubatsi bwa BMS

Hariho ubuhinga butatu bwa kera bwo kwubaka uburyo bwo gucunga amabateri. Gutoranya ibereye ahanini ni ikibazo c’ubunini bw’ipaki n’uburemere bwayo.

Itegeko ry’ingirakamaro dukoresha igihe dupima inyubako nshasha: munsi y’utugingo ngengabuzima nka 16 mu rutonde, gushirwa hamwe ni vyiza. Hagati ya 16 na 100, modular akenshi itsinda kugiciro-c'-ugushiraho n'ukwizigirwa. Hejuru y’ibice 100, vyatanzwe birihebera mu bijanye n’igiciro c’amabarabara, ubutungane bw’ikimenyetso, n’ubushobozi bwo gukoresha mu ndimiro. Ivyo ni intango, si amategeko; imigambi yihariye irashobora gukwega inzira iyo ari yo yose.
 

BMS n’Inama y’Uburinzi (PCM): Ni itandukaniro irihe?

Ivyo ni vyo bitera urujijo rumwe rudende mw’isoko rya BMS.

Nimba umucuruzi ariko arahamagara urubaho rw'amadolari 5 ku mpapuro z'utugingo ngengabuzima 10 "BMS," ubaze nimba ikora uburinganire bw'utugingo ngengabuzima, utanga raporo ya SOC ku bisi y'amakuru, kandi ushire ku rutonde inomero y'igice nyaco c'umugenzuzi w'utugingo ngengabuzima. Nimba inyishu ari oya, ni urubaho rwo gukingira.

Igituma BMS ihambaye: Ivyago nyavyo vyo kugenda ata n’imwe

Ijambo "igihambaye" rikoreshwa ataco rivuze. Ehe ivyo mu vy’ukuri bigenda nabi mu gipapuro ca litiyumu kitagira uburyo bwiza bwo gucunga amabateri, canke gifise ubunini buke bw’akazi.

Umutekano.Utugingo ngengabuzima twa litiyumu-iyoni turananirwa biciye mu nzira y’uruhererekane yitwa thermal runaway. Igihe c’imbere kigufi canke kirenze urugero kiraduga ubushuhe bw’ingingo imwe, ivyo bikaba bituma iyo ngingo yihuta gusenyuka, ivyo bikaba bituma ubushuhe burushiriza kuduga, gushika iyo ngingo isohoye umuyagankuba ushobora kwaka. BMS ifata ivy’imbere (umuriro udasanzwe, umuriro udasanzwe, ubushuhe budasanzwe) irashobora guca uruzitiro imbere y’uko ruhinduka umuriro.

Igihe c'ubuzima.Mbere n’ukudahukana gukomeye kw’amamilivolte mirongo hagati y’ingingo ngenderwako biragabanya cane ubuzima bw’amapaki. Igipande gikomeye kuruta ibindi vyose kiraheza kibanza gucagura maze kigaca kijabuka umurongo mutoyi; akagingo ngengabuzima gafise intege nke kuruta ibindi vyose ni ko gakora ivyo guterura ibintu biremerera kandi karakura mbere ningoga. Hatariho uburinganire, ubushobozi bwo gukoresha bw’ipaki buragabanuka mu buryo budahuye mu mezi aho kugabanuka mu myaka. Mu mapaki twafunguye inyuma y’aho garanti igarukiye, umurongo w’uburinganire utigeze ukora ni kimwe mu bintu bikunze gutuma ubushobozi butakaza imbere y’igihe.

Ibikogwa.Ata SOC na SOH zitagira amahinyu, iyo sisitemu ikoresha nabi ipaki (ubushobozi busigaye ku meza) canke ikayikoresha cane (ibirego canke igihe co gukora bidahuye n’ukuri). Ku bakoresha, "bateri yanje irapfa vuba cane kuruta uko ikimenyetso kivuga" ni hafi y'igihe cose ingorane ya BMS, si ingorane y'ingingo.

Gukurikiza amategeko.Ibintu vy’amabateri ya litiyumu muri iki gihe birakwegwakwegwa mu kirundo c’ingingo mfatirwako, kandi BMS nyayo ni yo akenshi ituma bishobora guca. Gusimbuka kimwe birafunga neza amasoko akomeye. Ivyo abantu bakunda kumenya cane:

• ONU 38.3: urutonde rw'ibigeragezo vy'umutekano vy'ugutwara-ivyo utugingo ngengabuzima twa litiyumu n'amapaki bitegerezwa guca kugira ngo birungikwe mu kirere, mu kiyaga canke mu nzira. Bisobanurwa n'Igitabo c'ibipimo n'ingingo z'ishirahamwe mpuzamakungu ONU.
• UL 2271: ipfuka amabateri y'ibinyabiziga bikoresha umuyagankuba nk'amagare y'umuyagankuba n'amapikipiki y'umuyagankuba.
• UL 1973: ivuga ku mirongo y’amabateri ahagaze n’agenda, harimwo n’ibikoresho vyinshi vya ESS. Bisaba inyandiko z’ukurinda BMS.
• IEC 62619: ingingo ngenderwako mpuzamakungu y’umutekano w’ibikoresho vy’inganda vy’ivyuma vy’ivyuma n’amabateri.
• ISO 26262: umutekano ukora w’ibinyabiziga vyo mu nzira. Bisabwa aho OEM ibivuga ku ma bateri y’ugukwega.

Kugira ngo ubone neza ivyo icemezo ca UL kirimwo ku ruhande rwa ESS, raba akajambo kacu kukuki ibicuruzwa vya BESS bikeneye icemezo ca UL. Ushobora kandi guca mu ngingo mfatirwako ubwazo biciye ku .Inyishu za UL.

Guhitamwo BMS ibereye hakurikijwe ugukoresha

Ibikorwa bitandukanye birashimika ku buryo bwo gucunga amabateri mu buryo butandukanye rwose. Iryo kimenyetso nyene "100A" risobanura ibintu bitandukanye cane mu gikoresho c'amashanyarazi no mu gikoresho co kubika izuba.

Ivyuma bikoreshwa n'umuyagankuba n'ivy'ugutembera

EVs na e-bikes zikeneye umuriro mwinshi ukomeza, inyishu y’isonga yihuta, SOC y’ukuri ku bijanye n’ugupima urugero, guhanahana amakuru CAN, na (aho OEM ibisaba) ISO 26262 ikora-umugambi w’umutekano. Ubwubatsi bw’ibice canke busanzwe ni bwo buganzwa ku mpera yo hejuru.

Uburyo bwo kubika inguvu (ESS)

Ububiko buhagaze bushira imbere ubuzima buramba bw’ikirangamisi, igiharuro kinini c’ingendo, gukurikirana neza SOH, n’ugukorana neza n’abahindura amakuru kuruta Modbus canke CAN. Ubusanzwe, utugingo ngengabuzima ni LiFePO4 kugira ngo tugire umutekano. Amadirisho y’umuriro manini (48V gushika kuri 800V+) asunika imigero ku BMSs zigizwe n’ibice canke zigabanywa. Ivyinshi mu vyacu .BESS iri mu bikoreshoimigambi, nk'akarorero, ikoresha BMS y'umuja-slave kugira ngo igikoresho cose gishobore gukoreshwa ata gutwara urubuga rwose kure y'umurongo.

Ibikoresho vy'amashanyarazi

Ibikoresho vy'amashanyarazi vyitaho isonga ry'amashanyarazi n'inyishu y'umurongo mugufi-hejuru y'ibindi vyose. Moteri ikwega amazi menshi cane y’igihe gito iyo itanguye no iyo ihagaze. Aha, ubushobozi bwa BMS bumanuka ku guhitamwo MOSFET (low Rds(on)) n’ubushobozi bwo gusohoka mu bisonga bigufi ata guhagarika bitera ingorane.

Ivyuma vy'ubuhinga bwa none vy'abaguzi n'ivy'abaguzi

Ubwinshi bukomeye, igiciro gito, n'ubufatanye bukomeye nivyo bihambaye cane. BMS ntoyi iri hagati ifise uburinganire butagira ico bukoze n’uburinzi bw’ishimikiro akenshi irahagije.

Ubuhinga bwo mu kiyaga no gutangura

Ibikorwa vy'uburyo bwa cranking- bisaba amashanyarazi menshi cane y'isonga ry'amazi ku biturika bigufi, hamwe n'uburinzi ku kunyiganyiga, ubukonje, n'umunyu. Rondera imigero ipfutse, isonga ry'isonga-ku-imigereranyo y'ubu ikomeza, n'uburinzi bukomeye bw'ubushuhe.

Ihitamwo ry’ubuhinga bwa shimi na ryo nyene rituma BMS itunganywa. Incamake yacu y'ubwoko butandukanye bwa bateri zo kubika inguvuagendagenda mu kuntu LFP, NMC, n’abandi bitwararika, ivyo na vyo bikaba bihindura imipaka y’umuriro, ingamba zo gufatanya, n’imipaka y’ubushuhe BMS itegerezwa gukurikiza.
