Izixhobo zebhetri zeLithium zineempawu ezithile ezithintela ukuba zingaphezulu, ngaphezulu-ikhutshiwe, ngaphezulu-Ngokwangoku, ijikelezwe njengokufutshane, kwaye ihlawuliswe kwaye ikhutshiwe kumaqondo obushushu aphezulu aphezulu. Ke ngoko, ipakeji ye-Lithium iya kuhlala ihamba kunye ne-BMS ecocekileyo. I-BMS ibhekisa kwiInkqubo yoLawulo lwebhetriibhetri. Inkqubo yolawulo, ikwabizwa ngokuba yiBhodi yokhuseleko.
Umsebenzi we-BMS
(1) Imbono kunye nomlinganiso wokulinganisa kukuqonda imeko yebhetri
Lo ngumsebenzi osisiseko weBms. amandla).
I-SOS inokuthi iqondwe ngokubanzi njengeyona nto ishiyekileyo kwibhetri, kwaye ixabiso layo liphakathi kwe-0-100%. Le yeyona parathu ibaluleke kakhulu kwi-BMS; I-Soh ibhekisa kwimo yezempilo yebhetri (okanye inqanaba lokuwohloka kwebhetri), lolona phawu lwebhetri yangoku. Xa kuthelekiswa nesikhundla esithintelwe, xa i-soh iphantsi kune-80%, ibhetri ayinakusetyenziswa kwimo yombane.
(2) I-alamu kunye nokukhusela
Xa ukungaqhelekanga kwenzeka kwibhetri, ii-BMs zikwazi ukuphelisa iqonga ukukhusela ibhetri kwaye lithathe amanyathelo ahambelana. Kwangelo xesha, ulwazi lwealamu olungaqhelekanga luya kuthunyelwa kwiplati nezokubeka esweni kunye nolawulo kwaye kuvelise amanqanaba ahlukeneyo olwazi.
Umzekelo, xa iqondo lobushushu livaliwe, ii-BMS ziya kukhutshelwa ngokuthe ngqo intlawulo kunye nesekethe yokukhupha, zenza ukhuseleko olungaphezulu, kwaye zithumele ialam ngasemva.
Iibhetri zeLithium ikakhulu zikhupha izilumkiso ngale micimbi ilandelayo:
Ngaphezulu: iyunithi enye ngaphezulu-I-Voltage, i-voltage iyonke-ivolthi, ukubiza ngaphezulu-okwangoku;
Ukukhupha ngaphezulu: Iyunithi enye phantsi-I-Voltage, i-voltage iyonke phantsi-ivolthi, ukukhutshwa ngaphezulu-okwangoku;
Iqondo lokushisa: Iqondo lobushushu lebhetri liphezulu kakhulu, iqondo lobushushu liphezulu kakhulu, iqondo lobushushu le-MOS liphezulu kakhulu, iqondo lobushushu lebhetri liphantsi kakhulu, kwaye iqondo lobushushu lebhetri liphantsi kakhulu;
Imeko: Ukuntywiliselwa kwamanzi, ukungqubana, ukungahambi, njl.
(3) Ulawulo olulungeleleneyo
Isidingo seUlawulo oluLungeleleneyokuvela ukungahambelani kwimveliso yebhetri kunye nokusetyenziswa.
Ukusuka kwimbono yemveliso, ibhetri nganye inomjikelo wakhe wobomi kunye neempawu. Akukho zibhende ezimbini zifana ngokuchanekileyo. Ngenxa yokungahambelani kwamadwa, amaKathode, ama-Ades kunye nezinye izinto, amandla eebhetri ezahlukeneyo azinakuhambelana ngokupheleleyo. Umzekelo, izikhombisi eziguquguqukayo ze-voltage, ukuxhathisa ngaphakathi, njl. Njl.
Ukusuka kwimbono yokusetyenziswa, inkqubo yokuphendula ye-electrochemical ayinakuze ihambelane ngexesha lokubhija kwebhetri kunye nokuyeka. Nokuba yipakethi efanayo yebhetri, intlawulo yebhetri kunye namalungelo okukhupha iya kwahluka ngenxa yobushushu obahlukileyo kunye needigri zorhwebo, ezikhokelela kubuchule beeseli zebhetri ezingahambelaniyo.
Ke ngoko, ibhetri ifuna bobabini uBiling ohambayo kunye nokulinganisa okusebenzayo. Oko kukuseta imigudu yokuqalisa ukuqalisa nokuphelisa ukulingana: umzekelo, kwiqela leebhetri, i-areyiciweyo iqalile xa i-50MV ifikelela kwi-50MV iphelele kwi-5MV.
(4) Unxibelelwano kunye nokuma
I-BMS inesakhiwo esahlukileyoImodyuli yoNxibelelwano, enoxanduva lokuhambisa idatha kunye nokubekwa kwebhetri. Ingadlulisela i-data efanelekileyo kwaye ilinganiswe kwiqonga lolawulo lwenkqubo ngexesha lokwenyani.
