Bateri ya Litiyumu BMS ya Forklifts: Ibiranga & Ubuyobozi bwihariye

Abashinzwe gutanga amasoko benshi baragereranyaforklift ibiciro bya batiriurebye kuri stikeri - $ 3000 yo kuyobora aside - aside, $ 15,000 kuri lithium. Kubara bisa nkibyoroshye kugeza ushize mubintu byihishe munsi yubuso. Bateri imwe ya forklift isaba iminota igera kuri 20 yo gufata amazi buri cyumweru. Hafi ya 20 - amato yibice mumyaka itanu, ibyo byiyongeraho ibihumbi icumi byamadorari yumurimo utigeze ugaragara kurutonde rwubuguzi. Sisitemu yo gucunga bateri ya BMS - niyo igena niba igishoro cya lithium yawe gitanga kuri ubwo bwizigame cyangwa gihinduka umutwe uhenze wicaye mu cyuma cyishyuza.

URASHOBORA guhuza protocole: Ikibazo cya sisitemu yubuhanga

CAN bus protocole ihuza iba ikibazo cya sisitemu yubuhanga mugihe amato yawe arimo ibirango birenze kimwe bya forklift. A.forklift ya batiri ya BMSUrupapuro rwerekana urutonde rwitumanaho - mubisanzwe CAN 2.0B, J1939, cyangwa RS485 - ariko ayo magambo ahinnye ntacyo asobanura kugeza igihe wemeje ko ukuboko gufatana mugenzuzi wawe. Sisitemu ya Curtis, Zapi, na Toyota buriwese yiteze ibihe bitandukanye. Shyiramo bateri ifite ubwubatsi bwa CAN budahuye, kandi forklift ishobora gutera kode yamakosa cyangwa ikora idafite leta yukuri - yamakuru yishyurwa agaburira ubwonko bwikinyabiziga.

Aha niho havanze - ibirango byerekana ibintu bigoye: ububiko bukora byombiIbice bya Linde na YaleNtushobora gutekereza ko utanga bateri imwe ikubiyemo byombi, keretse niba utanga isoko yemeje neza J1939 inkunga ya Yale ya VX hamwe na protocole ya Linde. Twabonye amatsinda yo gutanga amasoko aganira kugabanyirizwa byinshi gusa dusanga kimwe cya kabiri cya bateri zisaba nyuma ya CAN adapter zidafite agaciro ka garanti - ibisubizo bivanaho inyungu yibiciro burundu.

Igenzura rya Voltage Kurinda Mubyukuri

Buri bateri ya forklift ya BMS yerekana urutonde rwikurikiranabikorwa rya voltage, mubisanzwe hafi ± 0.5% hamwe na 1mV ikemurwa. Umubare wumvikana neza bihagije, ariko agaciro kayo katerwa nuburyo BMS ikemura ubusumbane bwakagari hejuru yibihumbi.

 

LiFePO4 selilekorera mumadirishya ya voltage - 2.5V hasi kugeza kuri 3.65V. BMS igenda ndetse na 2% kubisomwa bya voltage bizatera guhagarika imburagihe cyangwa, cyane cyane, kwemerera ibintu birenze urugero kuri selile zitandukanye mugihe ipaki - gusoma urwego rusanzwe. Niyo mpamvu garanti ya SOH (leta yubuzima) yabaye itandukaniro nyaryo mubatanga isoko. Shakisha ingwate zigaragaza 75% SOH mumezi 60 - ibisobanuro bifata gusa niba BMS ikomeje kugenzura neza kuri selile muri rusange.

 

Iyo tuvuze imishinga itatu - yimura ububiko bwububiko, icyemezo gikora na passiyo yo kuringaniza ibyemezo mubisanzwe bihindura umunani - umwaka wo kubungabunga umwaka wa 15-20%. Kuringaniza pasiporo bigabanya ingufu zirenze nkubushyuhe mugihe cyo kwishyuza, ikora kumikorere imwe -. Multi - ububiko bwububiko bugereranije 16+ amasaha buri munsi akenera kuringaniza kuri 1A - 5A, guhererekanya ingufu hagati ya selile aho kuyitesha. Ijanisha nyaryo riterwa numuzunguruko wawe hamwe nubushyuhe bwibidukikije - amakuru dukuramo muminsi 90 yambere yo gukora kugirango tunonosore projection.

ROI byubwoko bwibikorwa

Igihe cyo kwishyura cyawe giterwa nimpinduka imwe kurenza izindi: amasaha yo gukora burimunsi.

Ni ikihe cyiciro ibikorwa byawe biri? Twandikire hamwe namasaha yawe ya buri munsi nubunini bwa flet - tuzakoresha progaramu yawe ya ROI mugihe cyamasaha 48.

Ibyo Twubaka Bitandukanye

Ikinyuranyo cyibiciro hagati yabatanga bateri ya forklift akenshi igaruka kumurongo wa BMS, ntabwo ubuziranenge bwakagari. Bateri ya $ 10,000 hamwe na $ 7,000 ubundi irashobora gukoresha selile imwe ya CATL cyangwa EVE, ariko ubwubatsi bwa BMS buratandukanye - kandi itandukaniro rigaragara mubiganiro bya garanti, ntabwo ukwezi kwawe kwambere gukora.

Ubucucike bw'ubushyuhe:Dushyira ubushyuhe bwa NTC kuri selile ebyiri, bigafasha gutahura ubushyuhe bwumuriro mbere yubushyuhe butandukanye cascade. Ibice byingengo yimari bigabanuka kuri sensor imwe kuri module, bigakora ahantu hatabona hagati ya selile aho ubushyuhe bwirundanya vuba. Inshingano zamasezerano: garanti yacu isanzwe ikubiyemo ibintu byubushyuhe bidasaba icyemezo cyuko abakoresha bubahiriza. Abatanga ibicuruzwa bakoresheje module - urwego rwumva mubisanzwe bakora ibintu bidasanzwe kubijyanye n "ibidukikije bidakwiriye" - imvugo iguhindura uburyozwe mugihe hari ibitagenda neza.

Mu iperereza ryinshi rya bisi ya CAN twasuzumye, intandaro yerekana ibimenyetso bya bine ihuza itumanaho rya - kwambara kuri pine bitera gutakaza umwanya wo guhura, ibyo bikaba byerekana ko ari amakosa yamakosa atwara amasaha 2-4 yigihe cyo kwisuzumisha kuri buri kintu. BMS yacu itegura inzira CAN ikoresheje umuhuza winganda zongerewe imbaraga zingana na 10, 000+ kuzunguruka. Kumato yibice 50 ikora ibintu bibiri, iyo connexion yihariye yonyine irinda guhamagarwa kwisuzumisha ritateganijwe buri mwaka.

SOC algorithm neza:Gushyira mu bikorwa Kalman muyunguruzi bikomeza ± 3% SOC yukuri muburyo bwuzuye. Ibi nibyingenzi mugihe abakoresha bawe bacomeka mugihe cyo kuruhuka cya sasita - SOC idahwitse bivuze ko umuyobozi wa shift yaba asuzugura igihe gisigaye (guhura hagati - guhagarika inzira) cyangwa kubisuzugura (guta amadirishya yumuriro utanga umusaruro). Kimwe mu bikoresho byacu byo kugabura ibinyabiziga byongeye kubara ibikorwa remezo byo kwishyuza nyuma yo kubona amakuru ya SOC: bahagaritse sitasiyo ya kabiri yo kwishyuza, babitsa $ 18,000 byamafaranga yo kwishyiriraho.

Ibi ntabwo aribyiza byo kwigisha. Tuzaguhuza nabakiriya basanzwe bakora ibishushanyo bisa kugirango bahamagare - munsi ya NDA aho bikenewe.

Ibikorwa byoherejwe

Itandukaniro ryibiro rifata amato amwe.Batteri ya Litiyumuipima 40-60% munsi yicyuma gihwanye na - paki ya acide, byumvikana nkibyiza kugeza ubonye ko kubara kwa forklift kubara bireba ubwinshi bwa bateri. 3000 lb isasu - ipaki ya aside yasimbuwe na litiro 1.800 ihwanye na lisiyumu ihwanye bisaba kongeramo ballast - tonnage nyayo iratandukana na moderi ya forklift, uburebure bwa mast, hamwe nubushobozi bwo kuzamura. Turabibara mugihe cyo gusubiramo kandi dushyiramo ballast igaragara mugutanga.

Guhuza kwishyurwa nubundi buryo bwo gutanga amasoko binanirwa mubikorwa. Ibice bya Litiyumu BMS ivugana na charger kugirango icunge imyirondoro iriho; kuyobora - charger ya aside isunika umurongo uhamye wo kwirengagiza itumanaho. Gushyira bateri ya lithium hamwe na sisitemu iriho - charger ya aside ntabwo ikuraho garanti - yangiza selile. Bije yo gusimbuza charger cyangwa kwemeza uwatanze bateri itanga ibisubizo byuzuye byo kwishyuza byagenwe kuri voltage yawe (24V, 36V, 48V, 80V).

Ibyo ibihe byinshi byabacuruzi ntibakubwira: 50 - guhinduranya amato yumushinga ni umushinga wigihembwe, ntabwo ari weekend ndende. Ibyumweru bibiri byo kugenzura ingufu no kwiga ingufu, ibyumweru bine kugeza ku munani byo gutanga amasoko no kwemeza ibyemezo, umunsi umwe cyangwa ibiri kuri buri gice cyo gushiraho no guhinduranya ballast, icyumweru kimwe cyo guhugura abakoresha, hanyuma ukwezi kugenzura mbere yuko ibipimo bihagarara. Twubaka iyi ngengabihe mumasezerano kuburyo nta mpande zombi zitungurwa.

Aho Litiyumu idasobanutse

Twanze kubaza ibibazo bitatu byo guhindura amato mumezi atandatu ashize - imwe - ibikoresho byo guhinduranya hamwe no gukoresha bike, ibikorwa remezo bihari {{2} infrastructure ibikorwa remezo bya acide munsi yimyaka itatu, kandi nta gahunda yo kwagura. Kwishura byongerewe amezi 48 ashize muri buri kibazo, bivuze ko umukiriya ashobora gusimbuza forklifts mbere yo kugarura ishoramari rya batiri. Twahitamo gutakaza kugurisha kuruta kugira umukiriya werekana inkuru mbi ya ROI.

Ariko kububiko bwinshi - ububiko bwikigo, ibigo bikwirakwiza 24/7, ibikorwa byo kubika imbeho, cyangwa amato arenga ibice 10 hamwe na gahunda yo gukura, BMS - yatumye inyungu ziyongera vuba kuruta premium yimbere.

Intambwe Zikurikira

Twohereze ibicuruzwa byawe - ibirango bya forklift, amashanyarazi ya voltage, amasaha yo gukora burimunsi. Mu masaha 48, uzakira:

Amato yawe yihariye muri, nimero yawe hanze. Iyo niyo nzira.
