Ngokuthuthuka kwakamuva kwezobuchwepheshe, onjiniyela bekufanele bathole indlela efanelekile yokunika amandla izinto zabo eziqanjiwe.Amarobhothi ezinto ezizenzakalelayo, amabhayisikili kagesi, izithuthuthu, okokuhlanza, namadivayisi e-smartscooter konke kudinga umthombo wamandla osebenza kahle.Ngemva kweminyaka yocwaningo nokuhlola kanye namaphutha, onjiniyela banquma ukuthi uhlobo olulodwa lwesistimu yebhethri luvelele kwezinye: i-smart battery management system (BMS).Ibhethri elijwayelekile le-BMS line-lithium anode futhi liziqhayisa ngezinga lobuhlakani elifana nekhompyutha noma irobhothi.Uhlelo lwe-BMS luphendula imibuzo efana nokuthi, “Irobhothi lingazi kanjani ukuthi sekuyisikhathi sokuzishaja kabusha?”Okwenza imojuli ehlakaniphile ye-BMS ihluke ebhethrini elijwayelekile ukuthi ingakwazi ukuhlola izinga layo lamandla futhi ixhumane nezinye izisetshenziswa ezihlakaniphile.

Iyini i-Smart BMS?

Ngaphambi kokuchaza i-BMS ehlakaniphile, kubalulekile ukuqonda ukuthi iyini i-BMS ejwayelekile.Ngamafuphi, isistimu yokuphatha ibhethri ye-lithium evamile isiza ukuvikela nokulawula ibhethri elishajekayo.Omunye umsebenzi we-BMS ukubala idatha yesibili bese uyibika ngemva kwalokho.Ngakho-ke, ihluke kanjani i-BMS ehlakaniphile ohlelweni lokulawula ibhethri olusetshenziswayo?Isistimu ehlakaniphile inamandla okuxhumana neshaja ehlakaniphile bese izishayela yona ngokuzenzakalelayo.I-logistics ngemuva kwe-BMS isiza ukwelula impilo yebhethri futhi ikhulise ukusebenza kwayo.Njengomshini ojwayelekile, i-BMS ehlakaniphile incike kakhulu kusistimu ehlakaniphile ngokwayo ukuyigcina isebenza.Ukuze kuzuzwe ukusebenza okuphezulu, zonke izingxenye kufanele zisebenze ndawonye ngokuvumelanisa.

Amasistimu okuphatha ibhethri ekuqaleni (futhi asasetshenziswa) kumakhompyutha aphathekayo, amakhamera wevidiyo, izidlali ze-DVD eziphathwayo, kanye nemikhiqizo yasendlini efanayo.Ngemva kokwanda kokusetshenziswa kwalezi zinhlelo, onjiniyela bafuna ukuhlola imingcele yabo.Ngakho-ke, baqala ukufaka amasistimu ebhethri kagesi e-BMS ezithuthuthwini zikagesi, amathuluzi kagesi, ngisho namarobhothi.

Izingxenyekazi zekhompuyutha nezokuxhumana

Amandla aqhuba i-BMS yi-hardware ethuthukisiwe.Le hardware ivumela ibhethri ukuthi lixhumane nezinye izingxenye ze-BMS, njengeshaja.Ngaphezu kwalokho, umenzi wengeza eyodwa yalezi zisekelo zokuxhumana ezilandelayo: RS232, UART, RS485, CANBus, noma SMBus.

Nakhu ukubheka lapho ngalinye lalezi zisekelo zokuxhumana liqala ukusebenza:

• Iphakethe lebhethri le-lithiumnge-RS232 BMS ivamise ukusetshenziswa ku-UPS eziteshini zocingo.
• Iphakethe lebhethri le-lithium eline-RS485 BMS livamise ukusetshenziswa eziteshini zamandla elanga.
• Iphakethe lebhethri le-lithium eline-CANBus BMS livamise ukusetshenziswa kuma-scooters kagesi, namabhayisikili kagesi.
• Iphakethe lebhethri le-Ltihium eline-UART BMS lisetshenziswa kakhulu kumabhayisikili kagesi, futhi

Futhi Ngokujulile Bheka Ibhethri Lebhayisikili Logesi Lithium eline-UART BMS

I-UART BMS ejwayelekile inezinhlelo ezimbili zokuxhumana:

• Inguqulo: RX, TX, GND
• Inguqulo 2: Vcc, RX, TX, GND

Uyini Umehluko Phakathi Kwezinhlelo Ezimbili Nezingxenye Zazo?

Izilawuli ze-BMS nezinhlelo zithola ukudluliswa kwedatha nge-TX ne-RX.I-TX ithumela idatha, kuyilapho i-RX ithola idatha.Kubalulekile futhi ukuthi i-lithium ion BMS ibe ne-GND (umhlabathi).Umehluko phakathi kwe-GND enguqulweni yokuqala neyesibili ukuthi enguqulweni yesibili, i-GND iyabuyekezwa.Inguqulo yesibili iyona ndlela engcono kakhulu uma uhlela ukungeza i-optical noma i-digital isolator.Ukwengeza noma yikuphi kokubili, uzosebenzisa i-Vcc, okuyingxenye kuphela yesistimu yokuxhumana yenguqulo yesibili ye-UART BMS.

Ukukusiza ukuthi ubone ngeso lengqondo izingxenye ezibonakalayo ze-UART BMS ene-VCC, RX, TX, GND, sifake ukumelwa kwesithombe ngezansi.

Yini eyenza le sistimu yokulawula ibhethri ye-li ion iqhelelene nezinye ukuthi ungakwazi ukuyiqapha ngesikhathi sangempela.Ngokuqondile, ungathola isimo senkokhelo (SOC) kanye nesimo sezempilo (SOH).Nokho, ngeke ubone thola le datha ngokubuka nje ibhethri.Ukuze udonse idatha, udinga ukuyixhuma ngekhompyutha noma isilawuli esikhethekile.

Nasi isibonelo sebhethri le-Hailong eline-UART BMS.Njengoba ubona, isistimu yezokuxhumana imbozwe isivikelo sebhethri sangaphandle ukuqinisekisa ukuphepha nokusebenziseka.Ngosizo lwesofthiwe yokuqapha ibhethri, ukubuyekeza amamethrikhi ebhethri ngesikhathi sangempela kulula.Ungasebenzisa intambo ye-USB2UART ukuxhuma ibhethri kukhompuyutha yakho.Uma isixhunyiwe, vula isofthiwe yokuqapha ye-BMS kukhompyutha yakho ukuze ubone imininingwane.Lapha uzobona ulwazi olubalulekile njengomthamo webhethri, izinga lokushisa, i-voltage yeselula, nokuningi.

Khetha I-BMS Ehlakaniphile Elungile Yedivayisi Yakho

Nikeza inombolo yeibhethrikanye nabakhiqizi be-BMS, kubalulekile ukuthola labo abanikeza amabhethri ekhwalithi ephezulu ngamathuluzi okuqapha.Kungakhathaliseki ukuthi iphrojekthi yakho idingani, siyajabula ukuxoxa ngamasevisi ethu namabhethri esinawo.Uma unemibuzo mayelana nezinhlelo zokuphatha ibhethri ezihlakaniphile, ungangabazi ukusithinta.Sizokunikeza kuphela uhlelo olungcono kakhulu lwe-BMS futhi sikulungele ukukusiza ukuthi uthole olulungele izidingo zakho.
