Urukurikirane vs Bateri zibangikanye: Niki gihinduka imbere muri paki, nicyo kigutwara nyuma

Ingufu zimwe zabitswe, gabanya inzira ebyiri zitandukanye

Shyira paki ebyiri zisa 12V 100Ah hamwe kandi burigihe urangiza hamwe na watt 2,400 - amasaha yingufu. Ni uruhe ruhererekane hamwe no kugereranya bifata ibyemezo mubyukuriguteayo masaha ya watt - atangwa, nka voltage nyinshi cyangwa nka amp - amasaha menshi. Koresha paki ebyiri murukurikirane hanyuma ubone 24V kuri 100Ah. Kubitsindira kuburinganire kandi ubona 12V kuri 200Ah. Ingufu zose ntizigeze zigenda; gusa voltage - na - gutandukana kurubu.

Icyo gitekerezo kimwe niho usanga urujijo rwinshi rutandukanya urukurikirane nuburinganire bwa bateri ibangikanye itangira ikarangira, kuri terefone cyangwa itara.Ku kintu cyose gikoresha uruziga rw'inshingano gipimirwa mu mwanya aho kuba iminota, igice gishimishije ntabwo ari imibare. Nibibera kumupaki wa gatatu, ukwezi kwa mirongo ine, kandi mugitondo kimwe selile igwa muburinganire. Nicyo gice iki gitabo cyubatswe hafi. Niba ushaka imibare mbarwa mbarwa mbere, iyacumAh - kugeza - Guhindura ihinduka kubwimpamvu - ingano yingufuitwikiriye neza.

Gutondekanya urukurikirane: voltage izamuka, igumaho

Uruhererekane rw'uruhererekane ni iherezo - kugeza - iherezo ryanyuma, itumanaho ryiza rya paki imwe kuri negatif ikurikira, kugeza ugeze kuri voltage umugenzuzi wibikoresho byawe yiteze. Umuvuduko wongeyeho; amp - igipimo cyamasaha ntabwo. Ibice bine 12V bikurikirana biguha banki ya 48V iracyapimwe kubintu byose igice kimwe gitwaye.

Urukurikirane nuburyo ugera kuri voltage ya platform. Golf ya 48V - yimodoka, umugenzuzi wa trol 36V, inverter ya 24V, ntanumwe murimwe ukora mubushobozi; zikoresha kuri voltage, kandi urukurikirane rwa bateri nuburyo bwonyine bwo kubaka iyo voltage kuva munsi ya - voltage ya voltage.Icyiza kirenze gukubita intego: kuri voltage ndende imbaraga imwe ikurura ugereranije n'umuvuduko muke, bityo igihombo cya kabili kigwa kandi abayobora bagakonja. Urukurikirane - rwashyizweho na banki ya batiri isunika umutwaro uremereye uzabona ubushyuhe buke bwa I²R kurenza ugereranije bihwanye no gukora umurimo umwe kuri kimwe cya kane cya voltage.

Hano hari igisenge gikomeye gikwiye kuvuga izina hakiri kare. Iyo uruhererekane rw'uruhererekane ruzamutse hafi ya 50V, wambutse mu ifasi aho arc hamwe no guhungabana bishobora gusaba ingamba zifatika hamwe nibikoresho byabigenewe; ireka kuba intebe isanzwe. Hasi ya bine 12V ibice byumutekano ni byinshi; hejuru yacyo, fata umurongo wubaha 48V - wongeyeho sisitemu ikwiye. Uwo murongo wa 50V ntabwo ari itegeko ryinzu. Nibipimo ntarengwa byinganda - imyitozo yumutekano ya voltage ikoresha mugutandukanya akazi ka DC gasanzwe nibintu bikeneye inzira.

Kuringaniza kuringaniza: ubushobozi buzamuka, voltage ifata

Kuringaniza insinga ihuza ibyiza byose hamwe nibibi byose hamwe, mubisanzwe bigwa kuri bisi isanganywe aho kuba urunigi rwa dais. Umuvuduko ugumaho; amp - amasaha. Ibipapuro bitatu 12V 100Ah muburyo bubangikanye biguha 12V kuri 300Ah, kandi hafi inshuro eshatu mugihe cyo gukora kuri voltage.

 

Ibintu bibiri bituma parale ibangikanye ihuza ibikoresho bigomba gukomeza kugenda. Iya mbere ni igihe: urimo kongeramo imbaraga udakora kuri voltage umugenzuzi wawe yagenewe. Iya kabiri ni ukurenza urugero. Niba paki imwe iguye kumurongo, abarokotse bakomeza kugaburira umutwaro aho gufungura uruziga rwose. Ukwo kwihanganira amakosa nimpamvu ituje ibangikanye - banki za batiri zagenwe zigaragaza ahantu hose hateganijwe guhagarara bihenze.

 

Igiciro cyiyo mbaraga kirahari. Kongera ubushobozi kandi wikubye kabiri ibishoboka kuri bisi. Iyo miyoboro yinyongera, ntabwo ari voltage kandi ntabwo amp - nimero yisaha kuri label, niho banki zibangikanye zishobora guteza akaga, kandi ni urudodo dufata ibice bibiri hepfo.

Uruhande - kuruhande - kuruhande: voltage, ubushobozi, igihe cyo gukora, nibiki byananiranye

Impande nyinshi - by - ameza yuruhande ahagarara kuri "serie=volt, ugereranije=amp - amasaha," niyo mpamvu bateri ziri murukurikirane vs parallel ikaba ari ikibazo cyiza gikomeza kubona igisubizo kidakabije.Kugura amato akenewe ariko adahagije. Dore verisiyo ishushanya uburyo ip- ipaki yamashanyarazi yitwara muri serivisi:

Ikibazo kiza kwizerwa, kora bateri zimara igihe kinini murukurikirane cyangwa kuringaniza, gifite igisubizo cyiza kuruta interineti ibivuga.Kubera bateri imwe, ingufu zose zirasa, kandi urukurikirane rukora kumuyoboro muke kuburyo igihombo cyacyo cyaba gito. Ariko ubuzima bwa serivisi nyabwo bugenwa no kuringaniza selile hamwe nimyitwarire ya BMS kurenza kure ya topologiya ubwayo. Kwirukana "birebire - birambye" binyuze mu guhitamo insinga byonyine ni uguhindura impinduka zitari zo, niyo mpamvu rwose urukurikirane vs parallel bateri ya banki ya BMS ikibazo, ntabwo ari volt - na - amp - ikibazo cyamasaha, nicyo cyingenzi gikurikira.

Imipaka nyayo kumpapuro ushobora guhuza ntabwo ari imibare ya voltage, ni BMS

Dore impinduka nyinshi zitanga impapuro zitangwa ntizizashyira imbere yawe: urukurikirane rwa paki ya lithium hamwe nigisenge kibangikanye gishyirwaho na sisitemu yo gucunga bateri, ntabwo ari imibare yo kongeramo volt n'amasaha -. Iwacuprimer kuburyo BMS igenga pakiagendagenda muri logique yo kurinda inyuma yibi.

Ayo magambo nukuri, kandi ni naho ibitekerezo no kohereza bitandukana. Kuruhande rwurukurikirane, buri paki ya BMS igomba guhinduka no kwihanganiraUmuyoboro wuzuyehakurya ya FET yimbere mugihe cyamakosa, bityo igipimo cya voltage ya FET, ntabwo intego ya voltage ya banki yawe, niyo ntarengwa nyayo kuri bateri za LiFePO4 ushobora guhuza murukurikirane. Impamvu nyinshi za 12V moteri - amashanyarazi afite amanota agera kuri 4S ntarengwa, akamanuka hafi ya banki y'izina ya 51.2V, mubyukuri kuko aribyo ibyuma byo guhinduranya byujuje ibisabwa; uruganda rukora BMS rwihuza ruhoraho mukuvura urwo rutonde rwa FET, ntabwo ari voltage nominal, nkimbogamizi ihuza. Kuruhande rumwe, imbogamizi irahoraho, kandi ntabwo ihagaze neza. Igishushanyo mbonera cyerekana banki ihuriweho hamwe ikomeza kugeza kuri 90% yikigereranyo cya BMS, kubera ko ikigezweho ntigishobora kugabana neza mumapaki nyayo hamwe n’imbere - yo kurwanya. Kuri 80V / 500Ah igera - kubaka ikamyo, ko 10% dusiga nkana kumeza ni itandukaniro riri hagati yimigozi yose ikora muri dogere nkeya za mugenzi we numugozi umwe ucecetse utwara ibirenze umugabane wacyo.

Ikindi kimwe ubwira gitandukanya iriba - ryapakiwe hamwe nigiciro gihenze: LiFePO4 BMS nziza itangira kuringaniza selile hakiri kare, hafi 3.35–3.40V kuri selile, ntabwo iri hejuru yishyurwa. Igishushanyo gitegereza kugeza ingirabuzimafatizo ziri hejuru yazo kugirango ziringanize zirakubwira uburyo uwabikoze atumva chimie. Urwo rugabano ni byiza kugura ubwira kuruta urupapuro rwamamaza. Ariko urubariro rwonyine ntiruzakubwira niba ipaki ya gatatu - igizwe nishyakayaweukwezi; urutonde rwuzuye dukora iyo twujuje ibyangombwa byinjira byinjira mubuzima bwacuniki gitandukanya imwe ya forklift lithium pack nindi.

Kwishyuza bitwara ukundi, kandi bihana umurongo udakomeye

Urukurikirane vs parallel ya bateri yo kwishyuza niho harangirika byinshi byicecekeye. Mu ruhererekane rw'uruhererekane, charger ibona voltage imwe kuri stack yose, bityo selile ikomeye ikubita mbere yuzuye kandi kuringaniza umugozi bigomba kumena amaraso mugihe selile idakomeye iracyafata; gusimbuka kuringaniza neza kandi uteganya gukora cyane impera yumurongo buri cyiciro. Muri banki ibangikanye ingaruka zirahinduka. Huza udupaki tutari kumurongo umwe wo kuruhuka kandi urwego rwo hejuru rujugunya amashanyarazi muri hepfo ako kanya uhita ufunga umurongo, mbere yuko charger iba irimo. Gukosora kumpande zombi ntibishimishije: zana buri paki kumurongo umwe wamafaranga mbere yuko uyitsindira, hanyuma ukoreshe charger ihuye na voltage yukuri ya sisitemu. Nintambwe ibyananiranye murwego twahamagariwe byagaragaye ko twasimbutse.

Niki kitagenda neza kurwego rwa flet, nimpamvu ari gake selile

Kurwego rumwe - ipaki urwego ntanumwe muribi. Uburyo bwo kunanirwa bifite akamaro bugaragara iyo ugwije paki hejuru ya flet, kandi hafi ya ntanubwo chimie selile yananiwe; ni ibyemezo byimiterere bigufata.

Fata bisi ibangikanye. Ikibazo cyumutwe ntabwo insinga iba yoroheje cyane kuburemere busanzwe, niko bigenda iyo BMS imwe ipaki yananiwe nkigihe gito cyapfuye. Muri ako kanya, umugozi umwe ugaburira iyo paki urashobora gusabwa gutwarahamweikigezweho mubindi bikoresho byose kuri bisi. Ibipaki bitandatu buri kimwe cyapimwe 100A, kimwe cyapfuye kigufi, kandi ko umuyobozi umwe abona kugeza 500A itigeze iba nini. Ikirushijeho kuba kibi, niba irwanya imbaraga zayo zifata munsi yumupaka wurugendo rwarokotse, ntanumwe mubindi bice bya BMS wagize icyo akora, kandi insinga irateka.

Ninimpamvu yose yumuntu kugiti cye - umugozi uhuza kubaho, kandi nikintu "koresha umugozi uremereye" wibeshya. Iyo dushyizeho banki ibangikanye, kugabana kurubu kumurongo hafi ya byose ntibisoma byapfuye - no kumunsi wambere; bike ku ijana byo gukwirakwiza hagati yimigozi nibisanzwe, kandi nibyo rwose bikwirakwiza bihitamo umuyobozi uyobora cyane niba BMS irekuye. Ni ubuhe bunini kuri - kurinda umugozi mubyukuri bigomba kuba biterwa numubare wawe wuzuye, ibiranga urugendo rwa BMS, hamwe nimiterere ya bisi, kandi numubare umwe twahitamo kugereranya nigishushanyo cyawe - kuruta uko ubitekereza mu ngingo.

Uruhande rwurukurikirane rufite umutego warwo: intege nke - selile. Urukurikirane rw'imigozi yitwara nk'urunigi, kandi imwe munsi ya - ikora selile igenda igarukira ku mbibi zayo mbere. Kurura selile munsi ya 2.8V niyo rimwe kandi wangije burundu; ikintu kimwe hejuru ya - gusohora ibyabaye birahagije, kuri lisiyumu ya lisiyumu yatangajwe ntarengwa.Ubu nuburyo bukoreshwa na ba injeniyeri bacu bashushanya hafi yapaki, ahokuringaniza selile bituma ihuza intege nke gushiraho igisenge kumurongo wa 80V yose. Bifitanye isano, kandi nkuko bihenze: kuvanga paki nshya muri banki ishaje. Ibipapuro bishaje, birebire - byo guhangana bihatira ibishya ibitugu byinshi kumurimo kandi bikabishimangira ubudahwema; ntubona impuzandengo yabiri, ubona paki nshya itesha agaciro iyakera.

Urukurikirane - parallel: uko 48V na 80V byubatswe mubyukuri

Urukurikirane - iboneza rya batiri kubikoresho bya 48V cyangwa 80V bidakunze gutora topologiya imwe; irabahuza, kandi yego, urashobora guhuza bateri mukurikirane kandi ikabangikanya icyarimwe mugihe ubikora nkuko byateganijwe.Imigozi ya serie irashakishwa kugirango ikubite voltage ya platform, noneho iyo migozi irasa kugirango igere kubushobozi. Ibice cumi na bitandatu 12V bihinduka imirongo ine ya 48V ikurikiranye, hanyuma igahuzwa nubushobozi bumwe - ubushobozi 48V banki igaburira inverter nini cyangwa moteri. Aha niho igipimo cya "4S4P ntarengwa" kuri datasheet cyinjiza: kirakubwira ibahasha yujuje ibyangombwa ni bine bikurikiranye hamwe na bine muri iyo migozi ibangikanye, igisenge cya voltage nigisenge cyubushobozi muri numero imwe. Ibahasha ya 4S4P yubatswe kuva 12V 200Ah, nkurugero, niyo ifata platform ya 48V igera kuri 800Ah utiriwe usiga uruganda - rwujuje ibyangombwa, abakora inzira nyayo yo kwagura abakoresha bakoresha kugirango barambure igihe cyo guhinduranya kabiri.

Iyo capa ya 4S4P itera ikibazo gikwiye: kuki uhagarara aho mugihe physics yakwemerera byinshi? Igice cyigisubizo ni tekiniki. Biragoye rwose kugumisha imirongo myinshi ibangikanye kugabana kurubu uko kubara kuzamuka, kandi amabanki manini azamura imigabane kubapfuye - ibintu bigufi hejuru. Ibisigaye ni inshingano; uwabikoze yujuje ibahasha bashobora guhagarara inyuma. Kandi kera iyo ibahasha, inama zinyangamugayo ntizigaragara: ntugahingure - wubake. Kurenga 4S4P urimo kugenzura ugereranije ikwirakwizwa ryimyitwarire hamwe nimyitwarire yamakosa itsinda rusange ryo kubungabunga ridafite ibikoresho kugirango ryemeze, kandi rigomba gukorwa nkibikoresho byujuje ibyangombwa, ntabwo byakozwe kurubuga. Iyo dufashe amato arengana ibahasha, kugenzura - kugenzura ni cyo kintu cya mbere twiruka ku ntebe mbere y’ubwato bumwe. Kubikoresho bya 48V byumwihariko, voltage, charger hamwe n’ubucuruzi bwiyongera - inyuma yaya mahitamo birakwiye gusoma mbere yo kwiyemeza; urubuga rwacu rwa 48V rwo kugura ibiyobora.

Guhitamo iboneza ryimbaraga zitera inganda

Kuraho igishushanyo mbonera hanyuma icyemezo kiza kubyo ibikoresho byawe bisaba, murutonde:

• Umuyoboro wa mbere.Umugenzuzi arabitegeka. Ikamyo ya 48V ikenera banki ya 48V; urayubaka hamwe nurukurikirane rw'umugozi, guhagarara byuzuye.
   
• Noneho ubushobozi, kuburebure bwa shift.Iyo voltage imaze gukosorwa, imirongo ibangikanye igura igihe cyo gukuraho ibintu byuzuye, cyangwa bibiri hamwe nuburyo bwo kwishyuza.
   
• Noneho kwihanganira kunanirwa.Niba igice cyahagaritswe gihagarika umurongo, ubudahangarwa bwimiterere ibangikanye birakwiye gushushanya nkana.
   
• Noneho gahunda yo kurinda.Iyi niyo itagabanya kugenga igikumwe. Amapaki ahuye hamwe no kuringaniza hakiri kare ni ameza; kuri - umugozi uhuza, gutesha agaciro, hamwe na BMS ituma banki ya flet 80V ikomeza kubaho mugihe cyamakosa nyayo igenda igereranywa nigishushanyo cyihariye -, nicyo kiganiro cyo kugira mbere yuko paki ziri mumodoka, atari nyuma.

Kugereranya hagati yuruhererekane hamwe nuburinganire bwa bateri igereranya amato yinganda areka kuba abstract mugihe uyihuza ninshingano nyayo. Imyanya itatu - ihinduka igera - ikamyo ikora na wikendi - koresha GSE tugera kubisubizo bitandukanye bivuye muri fiziki imwe. Kubona ayo makarita neza kuri paki no kurwego rwa BMS nibyinshi mubitandukanya guhindura flet ikora bucece ikora imwe itanga terefone 2 am. Nicyo gice dukora nkubwubatsi, ntabwo ari ugukeka: Polinovel yashyizeho intego - ipaki yamashanyarazi kugeza CE, IEC, UL, UN38.3 na MSDS kubipimo bya 100+ OEM hirya no hino mubihugu 80+, hamwe na selile - kugeza kuri - kugenzura ubuziranenge kuri buri gice. Niba urimo kwerekana urukurikirane - parallel ya batiri ya banki kumurongo wihariye wa voltage na cycle yumurimo,tangira kubikoresho byawe nyabyo - ibisabwa kwisi hamwe nitsinda ryacu ryubwubatsikuruta kuva muri rusange.

Ibibazo
