Inkqubo yolawulo lwebhetri ye-lithium BMS — yisekethe emi phakathi kwepakethi yebhetri ye-lithium kunye neendlela iiseli ze-lithium ezingasebenzi ngayo. Naluphi na ulwakhiwo lwepakethi olunzima, nokuba yi-lithium-ion (NCM), i-LiFePO4, okanye i-LTO (i-lithium titanate), luthwala enye, kwaye ukuyicacisa kuxhomekeke kwizigqibo ezine: ikhemistri kunye nokubalwa kochungechunge ekufuneka ixhase, umbane oqhubekayo ekufuneka iwuthwale, unxibelelwano oluhambelana neemfuno zesicelo, kunye nendlela yokulinganisela egcina iiseli zilungelelene ubomi bepakethi.
Eli phepha lihamba ngendlela inkqubo yolawulo lwebhetri yeepakethe ze-lithium-ion kunye ne-LiFePO4 ezenzayo ngokwenene, emva koko isigqibo ngasinye kwezine sihamba ngokulandelelana, kunye noluhlu lweenkcukacha olugutyungelwa yi-DALY kwinqanaba ngalinye.
Oko kwenziwa yiLithium BMS
Yonke i-lithium BMS ineseti yokhuseleko olusisiseko: ukutshaja kakhulu, ukukhupha ngaphezulu, ukukhupha ngaphezulu, ubushushu, kunye nokhuseleko lwe-short-circuit. Ezi azizo iimpawu zeprimiyamu - zichaza udidi lwemveliso. I-BMS ijonga i-voltage yeqela ngalinye leseli kunye nobushushu bepakethi, kwaye iqhawula isekethe ephambili xa naluphi na ufundo ludlula umda walo wokhuseleko; ukubuyiselwa emva kokuba iimeko zibuyele kwifestile ekhuselekileyo, kunye nokuziphatha okuchanekileyo kokubuyisela kuxhomekeke kuhlobo lwempazamo.
Ngaphezu kwelo siseko, i-BMS ekrelekrele yongeza umlinganiselo onokuwubona kunye nezicwangciso onokuzitshintsha: ukufundwa kombane weseli ngeseli, uqikelelo lwemeko yetshaja, ukuqokelelwa kwembali, kunye nekhonkco leBluetooth kwi-app yefowuni yokubeka iliso kunye noqwalaselo lweeparameter. Izigqibo ezine ezingezantsi zimisela ukuba yeyiphi ibhodi ephethe loo misebenzi yephakheji yakho ethile.
Isigqibo 1 — Ubalo lweKhemistri kunye noLuhlu
Inkcazelo yokuqala yile yokuba le pakethi yenziwe ngantoni. I-DALY's Smart BMS (A Series) isebenzisa uyilo oluqhelekileyo lwe-4–24S (iiseli ezi-4 ukuya kwezingama-24 kuthotho) olugubungela iikhemikhali ezintathu eziphambili ze-lithium:
| Ikhemistri | Uluhlu lweNgcali eXhasiweyo |
|---|---|
| I-LiFePO4 (LFP) | 4–8S / 7–17S / 7–24S |
| I-Lithium-ion (i-NCM) | 4–7S / 7–17S / 7–20S |
| I-LTO | 6–8S / 11–17S / 11–24S |
Imisebenzi emibini yenza uyilo oluqhelekileyo lube luncedo kwimveliso. Ikhemistri inokutshintsheka kwi-app ye-DALY ngokucofa kube kanye, ngoko ke ibhodi efanayo ikhonza i-oda ye-LFP kule nyanga kunye ne-oda ye-NCM kwinyanga ezayo. Kwaye inani lothotho lifunyanwa ngokuzenzekelayo kwimizuzwana engama-45 yokuvula amandla okokuqala - akukho switshi ze-DIP, akukho lungiselelo ngeyunithi nganye - oko kuthetha ukuba ipakethi yebhayisekile ye-13S kunye nepakethi ye-16S 48V zinokuthunyelwa ukusuka kwisitokhwe esifanayo se-BMS.
Isigqibo 2 — Inqanaba langoku eliqhubekayo
Uvavanyo lwangoku sisigqibo esineziphumo ezithe ngqo zeendleko: ucacisa kakhulu kwaye uhlawulela ubhedu ongalusebenzisiyo; ucacisa kancinci kwaye i-BMS iyaqhawuka phantsi komthwalo osemthethweni. Uthotho lwe-A lugubungela amanqanaba amane:
| Inqanaba langoku | Iqhubekeka | Incopho |
|---|---|---|
| 40A / 60A | 40A / 60A | 60A / 90A |
| 80A / 100A | 80A / 100A | 120A / 150A |
| 150A / 200A | 150A / 200A | 225A / 300A |
| 250A–400A | 250A / 300A / 400A | 375A–600A |
Ukuhlolwa okubini kuchaza inqanaba. Okokuqala, fanisa umlinganiselo oqhubekayo nomthamo oqhubekayo, hayi i-nameplate maximum yayo. Okwesibini, jonga ikholamu yencochoyi ngokuthelekisa iziganeko zokukhuphuka kwesicelo — ukuqala kwemoto, ukunyuka kwe-inverter — kuba lumlinganiselo wencochoyi, hayi oqhubekayo, ogqiba ukuba i-BMS ihamba kuzo na. Apho imfuneko yephakheji idlula i-400A ngokuqhubekayo,umgca we-BMS osebenza ngamandla aphezuluithatha indawo.
Isigqibo 3 — Unxibelelwano
Ipakethi ekhusela kuphela igqibelele ngendlela esebenza ngayo; ipakethi ebikayo ithengiswa kakuhle. I-A Series iza ne-UART ezimbini, i-RS485, kunye ne-CAN njengeendawo zokunxibelelana eziqhelekileyo, kunye ne-Bluetooth eyakhelwe ngaphakathi kwi-app ye-DALY. Ukuba yeyiphi na esetyenziswa yi-app yakho ixhomekeke kwinto ehleli kwelinye icala lentambo: ii-inverters kunye neetshaja kwiinkqubo zokugcina kunye nokuhamba zihlala zithatha i-RS485 okanye i-CAN, ngelixa i-UART idla ngokukhonza iiyunithi zokubonisa kunye nabalawuli be-host.
Umbuzo obalulekileyo ngeenkcukacha asikokuba "yeyiphi ibhasi engcono" kodwa "yintoni ethethwa sisixhobo sokwamkela" — kwaye ngenxa yokuba zonke ezi ndawo zintathu zonxibelelwano zikwibhodi enye, imodeli enye ye-BMS igubungela abathengi kwiibhasi ezahlukeneyo ngaphandle kotshintsho lwehardware.
Isigqibo 4 — Ukulinganisela
Iiseli ziyaqhekeka ngokuhamba kwemijikelo yokutshaja, kwaye indlela yokulinganisela imisela ukuba ingakanani i-BMS enokuyilungisa i-drift. I-A Series ithwala i-100mA passive balancing njengomgangatho — eyaneleyo ukubamba iiseli ezintsha ezihambelana kakuhle kumgca kwinkonzo eqhelekileyo.
Xa ukuhambelana kweseli kungumqobo — iiseli ezinomthamo omkhulu ezineeseli ezisasazeka ngokubanzi, ubomi besibini, okanye iipakethi ezijikeleza nzulu yonke imihla —I-T Series esebenzayo yokulinganisela i-BMSihambisa amandla phakathi kweeseli ukuya kuthi ga kwi-1A isebenzisa i-bidirectional transformer balancing, kuluhlu olufanayo lwe-4–24S, kumanqanaba angoku ukusuka kwi-40A ukuya kwi-400A. I-tier ye-30A ene-0.5A inductive active balancing ikwafumaneka kwizakhiwo ezincinci ze-12V LiFePO4. I-specification logic ilula: i-passive balancing ngokuzenzekelayo, i-active balancing xa iiseli, kungekhona i-current rating, ziyi-limiting factor.
Ukuhlanganisa Izigqibo Ezine
Inkcazo epheleleyo ye-lithium BMS ifundeka ngolu hlobo: ikhemistri kunye nokubalwa kochungechunge (umz., i-16S LiFePO4), umsinga oqhubekayo one-peak check (umz., i-100A eqhubekayo / i-150A peak), ii-interfaces ezifunekayo (umz., i-CAN kwi-inverter), kunye nendlela yokulinganisela (ingasebenzi kwiiseli ezintsha ezihambelanayo). Xa ezo parameter zine zilungisiwe, ibhodi iyazikhethela yona —Uluhlu lweSmart BMS (A Series)igubungela uluhlu olupheleleyo lwe-4–24S / 40A–400A, kwaye uthotho lwe-T lugubungela uluhlu olufanayo ngokulinganisela okusebenzayo.
Imibuzo ebuzwa qho
Q1Ngaba imodeli enye ye-BMS ingagubungela ngokwenene i-4S ukuya kwi-24S?
I-A Series igubungela i-4–24S ukuya kwiindlela ezintathu zokucwangcisa uluhlu (lwe-LiFePO4: 4–8S, 7–17S, kunye ne-7–24S). Ngaphakathi koqwalaselo, inani lochungechunge lifunyanwa ngokuzenzekelayo kwimizuzwana engama-45 yokuvula amandla okokuqala — ipakethi ye-13S kunye nepakethi ye-16S zisebenzisa ibhodi efanayo ngaphandle kokuseta ngesandla. Inzuzo yempahla: iindlela ezintathu zokucwangcisa zigubungela ii-voltage zepakethi ukusuka kwi-12V-class ukuya kwi-60V-class nangaphezulu, endaweni yemodeli eyahlukileyo nge-voltage nganye.
Q2Yintoni umahluko phakathi kokulinganisela okungasebenziyo kunye nokusebenzayo?
Ukulinganisela okungasebenziyo kukhupha umbane ogqithisileyo kwiiseli eziphezulu njengobushushu, kwi-100mA kwi-A Series — ngokwaneleyo kwiiseli ezintsha ezihambelana kakuhle. Ukulinganisela okusebenzayo kuhambisa amandla ukusuka kwiiseli eziphezulu ukuya kwiiseli ezisezantsi, ukuya kuthi ga kwi-1A kwi-T Series — kwiipakethi apho ukuhambelana kweseli kuhamba ngokukhawuleza kunokuba ukulungiswa okungasebenziyo kunokubamba, njengeeseli ezinomthamo omkhulu okanye ubomi besibini.
Q3Ndingakhetha njani phakathi kwereyithingi yangoku eqhubekayo nephezulu?
Cacisa umlinganiselo oqhubekayo ukusuka ekutsaleni okuqhubekayo komthwalo, kwaye uqinisekise umlinganiselo ophezulu ngokuchasene neziganeko zokunyukela njengokuqala kwemoto. Zombini ezi zilingo kufuneka ziphumelele: i-BMS enomlinganiselo kuphela kumbane oqhubekayo iya kuqhawuka ngexesha lokunyukela; omnye onomlinganiselo kuphela kwiincopho uthwala iindleko ezingafunekiyo.
Malunga neDALY
I-DALY iyila kwaye ivelise iinkqubo zolawulo lweebhetri ze-lithium zabavelisi beepakethi, ii-OEM, kunye nabahlanganisi, kunye neemveliso ezisetyenziswa kumazwe angaphezu kwe-130. Yasekwa ngo-2015, i-DALY inika isiqinisekiso sobunjineli ngaphambi kokuthengiswa kunye nenkxaso yokufanisa iinkcukacha kwiiprojekthi zemveliso.
