Nangona i-lithium-ion ibhetri ine Uxinizelelo oluphezulu lwamandla, banokuba sengozini yokufikelela kwiimeko ezinokonakalisa ipakethe yebhetri. Kungenxa yoko le nto sifuna inkqubo yolawulo lwebhetri ukunceda ukuthintela iimeko ezonakalisayo.
Inkcazo
A Inkqubo yoLawulo lwebhetri (ii-BMS) Ngaba isiphaluka se-elektroniki esibeka iliso kwaye silawula ukutshaja kunye nokukhutshwa ibhetri enokuphinda yenziwe.
Iqinisekisa ukuba ibhetri isebenza ngaphakathi kwemida yokhuseleko, ebaluleke kakhulu kwibhetri kunye nobomi obude.
Iindidi zeenkqubo zolawulo lwebhetri
Iinkqubo zolawulo lwebhetri ixesha ukusuka ukusuka kwinqanaba elilula ukuya kokuntywila, kubandakanya itekhnoloji eyahlukileyo yokunyamekela iibhetri. Ezi nkqubo zinokuhlelwa ngokwahlukeneyo nge-topology yazo – Ifakiwe njani kwaye isebenza kuzo zonke iiseli zepakethi zepakethi okanye iimodyuli.
Uyilo lwe-BMS ephakathi
I-BMS ephakathi kwipakethi yebhetri ibonelela ngeenzuzo, ezinjengokuthintela i-compact kunye nezoqoqosho.
Nangona kunjalo, nayo iyabamba.
Ngazo zonke iibhetri ezinxulumene ngqo, i-BMS ifuna amazibuko amaninzi, ekhokelela kwi-wiring entsokothileyo kunye ne-cabling kwipakethi enkulu yebhetri. Oku kugxile kukugcina ingxaki kunye nokugcinwa kwayo.
Imodyuli ye-BMS
Ngolu hlobo lwe-BMS, le nkqubo yahlulwe yangeimodyuli eziphindwe kabini, nganye iqhagamshelwe kwinxalenye eyabelwe inxenye eyabelwe ibhetri.
Imodyuli eyi-BMS ephambili inokubangela i-subsodussus, ukubeka iliso kwimeko yabo kunye nokunxibelelana nezinye izixhobo. Imodyuli ephindwe kabini yenza lula ukucocwa, ulondolozo, kunye nokwandiswa kweepakethi ezinkulu zebhetri.
Nangona kunjalo, le ndlela yonyusa kancinci iindleko ngokubanzi kwaye inokubangela ukusebenza okungasetyenziswanga, kuxhomekeka kwisicelo.
I-BMS eyintloko / engaphantsi
Ngokufanayo nakwimodyuli yemodyuli yemodyuli, kule meko, i-Sheves ngokuyintloko idlulisela ulwazi, ngelixa i-Master iphatha unxibelelwano, ulawulo kunye nonxibelelwano lwangaphandle.
Ukusebenza kwekhoboka kulula, kuncitshiswe iindleko ngenxa yentloko engaphezulu kunye neempawu ezimbalwa ezingasetyenziswanga, njengeentlobo zemodyuli.
I-BMS ye-BMS esasazwayo
I-BMS ye-BMS esasazwayo yahlukile kwezinye izipholo.
Babandakanya zonke izixhobo ze-elektroniki kwiBhodi yoLawulo ibekwe ngokuthe ngqo kwiseli okanye kwimodyuli esweni. Oku kunciphisa ukungena kwi-sebling kwinzwane kunye neengcingo zonxibelelwano phakathi kweemodyuli ze-BMS. I-BMS nganye iyodwa, iqulathe iindetshi kunye nonxibelelwano njengoko kufuneka.
Nangona kunjalo, le fomu idibeneyo inokwenza ingxaki kunye nesondlo kunzima ngakumbi, njengoko i-BMS ihlala ngaphakathi kwemodyuli ekhuselweyo.
Iindleko ziphezulu ngenxa yenani elonyukayo leeyunithi ze-BMs kwipakethi yebhetri.
Yintoni umsebenzi wenkqubo yolawulo lwebhetri?
Inkqubo yolawulo lwebhetri ibeka iliso kwaye ilawule iiparamitha zebhetri, ukulinganisa okwangoku, i-voltage, kunye neqondo lobushushu esekwe kwiimfuno zenkqubo. I-IT ilungelelanisa iiseli zentlawulo (ibala lebhetri (SOS) kunye nemeko yempilo (SOH).
I-BMS ithintela i-voltage ephezulu, ubushushu obungaphezulu, kunye neminye imingcipheko ngokulawula ukutshaja kunye nokuhambisa iinkqubo. Kubalulekile ekuqinisekiseni ukuba ibhetri kunye nokhuseleko lwabasebenzisi.
Umsebenzi wonxibelelwano uguqula imiqondiso phakathi kwamacandelo e-BMS yangaphakathi kunye nezixhobo zangaphandle. I-BMS inokubonisa idatha kwi-DASHBODS okanye i-project yabantu (i-HMM). Unxibelelwano ngetshaja, idityanisiwe okanye yahlukile, inokuwisa okanye ingenazingcingo.
Kutheni inkqubo yolawulo yebhetri ibalulekile kwiibhetri ze-lithium-ion
Ibhetri yeLithium-ion inolwelo olunokutsha olunokutsha, ke kufuneka isebenze ngokupheleleyo nangaphakathi kwemida yokhuseleko ukuthintela imililo.
Isebenza njani inkqubo yolawulo lwebhetri?
Inkqubo yolawulo lwebhetri, iqhagamshelwe kwiinzwa, ibeka iliso kwi-voltage nganye yeseli, yangoku kunye nobushushu. Uhlalutya idatha yokuqinisekisa ukuba iiseli zisebenze ngaphakathi kweparameters kwaye ithathe inyathelo lokusombulula imicimbi.
I-BMS ilawula inkqubo yokupholisa kwiqondo lokushisa kwibhetri ukuba iiseli ezigqithileyo. Ikwalinganisa iiseli ngokudlulisela amandla phakathi kwabo ukugcina i-voltages elinganayo.
I-BMS yokungena kwidatha yokuvavanya amandla angenayo kunye nokuphuma kwepakethi yebhetri kunye nempilo ngokubanzi. Iibhetri zeLithium-ion Sebenzisa le datha ukufumana ukuba ibhetri ikhutshelwe kwaye ivaliwe. Kungenxa yoko le nto bengabonisi imiqondiso yokufa efanayo neebhetri ezikhokelayo, kodwa cima.
Zithini izibonelelo zenkqubo yolawulo lwebhetri?
IziBonelelo ze-BMS zibandakanya:
- Umsebenzi wokhuseleko ngakumbi I-Lithium-ion yebhetri, Thintela imililo kunye nomonakalo
- Ukwandiswa kwe-Lifespan yebhetri kunye nokuthembeka ngokulawula iiseli ngaphakathi kwemida yokusebenza ngokukhuselekileyo
- Yenza umsebenzi webhetri kwaye udluliselwe Ukulungelelaniswa kweseli
- Ukubonelela ngoxilongo, ukuqokelelwa kwedatha, kunye nonxibelelwano kwimeko yebhetri
- Ukunciphisa iindleko kunye namabango amabanjwa ngokukhusela inkqubo yebhetri
Ukhuseleko olunikelwa yinkqubo yolawulo lwebhetri
Ukhuseleko lwenkqubo yolawulo lwebhetri ilapha ngezantsi:
Ngaphantsi nangaphezulu kwe-voltage
I-BMS ikhusela iiseli zebhetrium ze-lithium-ion yomonakalo obangelwe yi-Oversaged (i-voltage yeseli ephakama kakhulu) okanye ngaphezulu-ukukhululwa kombane (i-voltage yeseli iphantsi kakhulu). Ithintela phantsi kweemeko zokuvota okungaphezulu nangaphezulu ezinokwenzakalisa ibhetri.
Ubushushu obugqithisileyo
I-Lithium-ion yoKhuseleko lwebhetri kunye nokuzinza kuxhomekeke kulawulo lobushushu. Ngaphezulu kwemida ebalulekileyo inokubangela ukubaleka kwe-thermal Imililo engaguqukiyo.
I-BMS ibeka iqondo lobushushu, ilawula abalandeli abapholileyo, kwaye inokuzivalela iiseli ukuze zigcine iimeko ezifanelekileyo.
Ukhuseleko kwiifutshane
I-thermal ibaleka inokwenzeka ngenxa yefutshane ngaphakathi nangaphandle.
Ke ngoko, ukukhuselwa kwifutshane yinxalenye ebalulekileyo yenkqubo yolawulo lwebhetri.
Ibhetri yeHlolo eyakhelwe kwinkqubo yolawulo lwebhetri
Ibhetri yeHolo ibonelela ngeendlela zokukhusela i-BMS yesiko sokukhusela ngokusilela kwebhetri eqhelekileyo kubangela isebutheni emifutshane, imijikelezo ephezulu, amaqondo obushushu agqithisileyo, kunye nemiba yokuvota.
I-BMS yethu yeza ngobukhulu obahlukeneyo ukuze ilingane neseti yakho, kwaye ixhasa ubomi bebhetri kwaye ibonelele ngedatha yokusebenza.
Nokuba ngaba ukunkcenkceshela izixhobo ezincinci okanye iinkqubo ezinkulu zamandla, sibonelela ngezisombululo ezinokuthenjwa, ezisebenziseka lula ze-BMS.
Ukuqukumbela
Ibhetri yeLithium-ion inika izibonelelo ezininzi, kodwa funa ukubeka esweni, ukuphatha, kunye nokulinganisa ukuqinisekisa ukhuseleko kunye nobomi obulungileyo. Inkqubo yolawulo lwebhetri iphambili, ukugcina iibhetri ezisebenza ngokukhuselekileyo nangokufanelekileyo ukuze uzisebenzise ngokuzithemba.
