Inkqubo yolawulo lwebhetri (i-BMS) idlala indima ebalulekileyo ekuqinisekiseni ukusebenza ngokukhuselekileyo kunye nokusebenza ngokufanelekileyo kweebhetri ze-lithium-ion, kubandakanya i-LFP kunye neebhetri ze-LFP kunye ne-NCM / NCM / NCM / NCM / NCM. Eyona njongo yayo iphambili kukubeka iliso kwaye ulawule iiparamitha ezahlukeneyo zebhetri, ezinje nge-voltage, ubushushu, nangoku, ukuqinisekisa ukuba ibhetri isebenza ngaphakathi kwemida. I-BMS ikwakhusela ibhetri ukuba ingaphezulu, ikhutshiwe ngaphezulu, okanye isebenza ngaphandle kwenqanaba lokushisa. Kwiipakethi zebhetri ngothotho lweeseli (iintambo zebhetri), i-BMS ilawula ukulungelelana kweeseli ezizodwa. Xa i-BMS iyasilela, ibhetri ishiywe isesichengeni, kwaye imiphumo inokuba nzima.
1. Ukunyanzelwa okanye ukukhululeka ngaphezulu
Enye yezona zinto zibalulekileyo ze-BMS kukuthintela ibhetri ukuba ingaphezulu okanye ikhutshiwe ngaphezulu. Ukunyanzelwa kuyingozi ikakhulu kwiibhetri zebhetri eziphezulu ze-ternary lithium (i-NCM / NCA) ngenxa yokuzibandakanya kwabo kwi-themevaway ye-thermal. Oku kwenzeka xa i-voltage yebhetri ingaphezulu kwemida ekhuselekileyo, ivelisa ubushushu obugqithisileyo, obunokukhokelela ekuqhubeni okanye umlilo. Ukukhupha ngaphezulu, kwelinye icala, kunokubangela ukonakala okungapheliyo kwiiseli, ngakumbi kwiibhetri ze-LFP, ezinokuphulukana nentsebenzo kwaye zibonise intsebenzo engezantsi emva kokukhutshwa okunzulu. Kuzo zombini iindidi, ukusilela kwe-BMs ukulawula i-voltage ngexesha lokubhija kunye nokukhupha kunokukhokelela kumonakalo ongenakuphikiswa kwipakethi yebhetri.
2. I-Gradeal kunye ne-thermal ibaleka
Iibhetri ze-ternary lithium (i-NCM / NCA) zinovelwano kakhulu kubushushu obuphakamileyo, ngakumbi iibhetri ze-thalfp, ezaziwa ukuzinza komzimba okungcono. Nangona kunjalo, zombini ezi ntlobo zifuna ulawulo lobushushu ngononophelo. I-BMS esebenzayo ibeka iliso kubushushu bebhetri, iqinisekisa ukuba ihlala ngaphakathi koluhlu olukhuselekileyo. Ukuba i-BMS iyasilela, inokwenzeka i-gesiating inokwenzeka, iphele i-chain eyingozi ebizwa ngokuba yi-thermal ebalekayo. Kwipakethi yebhetri edityaniswe kuthotho lweeseli (iintambo zebhetri), ukubaleka kwetekisi kunokusasaza ngokukhawuleza kwisisele esinye ukuya kwesinye, okukhokelela ekungaphumelelweni kwentlekele. Ukuze ufumane izithuthi zombane, lo mngcipheko uyakhuliswa kuba ukuxinana kwamandla kunye nokubala kweseli kuninzi kakhulu, ukwandisa amathuba okuba nemiphumo emibi kakhulu.
I-3. Ukungalingani phakathi kweeseli zebhetri
Kwiipakethi zebhetri ezininzi, ngakumbi abo banoxanduva lokuqina kweevolimu ezifana nezithuthi zombane, ukulinganisa i-voltage phakathi kweeseli kubalulekile. I-BMS inoxanduva lokuqinisekisa zonke iiseli kwipakethe ilungelelaniswe. Ukuba i-BMS iyasilela, ezinye iiseli zinokugqithiswa ngaphezulu ngelixa abanye baqhubeka nokwamkelwa. Kwiinkqubo ezinomtya webhetri ezininzi, oku ukungalingani akuyi kunciphisa impumelelo ngokupheleleyo kodwa kukwabeka ingozi yokhuseleko. Iiseli ezigqithisileyo zisengozini yokugcwala, enokubangela ukuba zisilele ngokwenyani.
4. Ukuphulukana nokubekwa kweliso kunye nokungena kwedatha
Kwiinkqubo zebhetri ezintsokothileyo, ezinjengezo zisetyenziswa kugcino lwamandla okanye kwizithuthi zombane, i-BMS ngokuqhubekayo ibeka iliso kwibhetri, ukuqhubeka kwedatha kwimijikelezo ehlawulayo, i-voltage, iqondo lempilo. Olu lwazi lubalulekile ekuqondeni impilo yeepakethi zebhetri. Xa i-BMS iyasilela, le misebenzi yokubeka esweni ibalulekileyo, yenze ukuba ayinakwenzeka ukuba ilandele indlela ezisebenza kakuhle ngayo iiseli kwipakeji. Kwiinkqubo zebhetri eziphakamileyo ze-voltage ezinoluhlu lweeseli ezininzi, ukungakwazi ukubeka iliso kwimpilo yeseli kunokukhokelela ekungathobeleni okungalindelekanga, njengokuphazamiseka kwamandla enzonzobila okanye imicimbi yengozi.
5. Ukusilela kwamandla okanye ukuncitshiswa kokusebenza kakuhle
I-BMS engaphumelelanga inokubangela ukuncitshiswa kokufanelekileyo okanye ukusilela kwamandla ngokupheleleyo. Ngaphandle kolawulo olufanelekileyo lweI-Voltage, ubushushu, kunye nokulungelelaniswa kweseli, le nkqubo inokuvala ukunqanda ukonakala ngakumbi. Kwizicelo aphoI-WightBabandakanyeka, njengezithuthi zombane okanye ukugcina amandla omzi-mveliso, oku kunokukhokelela ekuphulukaneni ngequbuliso kwamandla, kubeka umngcipheko omkhulu wokhuseleko. Umzekelo, aI-Ternary LithiumIpakethe yebhetri inokuvala ngequbuliso ngelixa imoto yombane ihamba, yenza iimeko zokuqhuba eziyingozi.
