Luyini uhlelo lokuphathwa kwebhethri (BMS)?
Igama eliphelele leI-BMSIngabe uhlelo lokuphatha ibhethri, uhlelo lokuphathwa kwebhethri. Kuyithuluzi elisebenzisana nokuqapha isimo sebhethri lesitoreji samandla. Ikakhulu ekuphathweni okuqondayo kanye nokugcinwa kweyunithi ngayinye yebhethri, ukuvikela ibhethri kusuka ekutholeni ngokweqile nasekulahlekelweni ngokweqile, ukwandisa impilo yebhethri, kanye nokuqapha isimo sebhethri, kanye nokuqapha isimo sebhethri, kanye nokuqapha isimo sebhethri. Ngokuvamile, i-BMS imelwe njengebhodi yokujikeleza noma ibhokisi lehadiwe.
I-BMS ingenye yezindlela ezingaphansi kwesisekelo sohlelo lokugcina amandla ebhethri. Ibhekele ukuqapha isimo sokusebenza kwebhethri ngalinye kuIsitoreji Sendla sebhethriiyunithi yokuqinisekisa ukusebenza okuphephile nokuthembekile kweyunithi yokugcina amandla. I-BMS ingaqapha futhi iqoqe amapharamitha wombuso webhethri lesitoreji samandla ngesikhathi sangempela (kufaka phakathi amandla okusebenza kwebhethri, i-voltage yebhethri yebhethri, njll.ibhethri lokugcina amandlaUmzimba ubonakala ngokuya ngecebo elithile lokuvikela ukuvikelwa, ukuze uqinisekise ukusebenza okuphephile nokuthembekile kwalo lonke iyunithi yokugcina yebhethri. Ngasikhathi sinye, i-BMS ingashintshana ngolwazi neminye imishini yangaphandle (ama-PC, i-EMS, okokuvikela umlilo, nokufaka okubonakalayo, kanye nokwethembeka kokuphepha kwesiteshi samandla, ukusebenza kahle kwegridi.
Uyini umsebenzi weI-BMS?
Kunemisebenzi eminingi ye-BMS, kanye nemisinga ebaluleke kakhulu, esikukhathalela kakhulu, asizitholi ngaphezu kwezinto ezintathu: ukuphathwa kwesimo, ukuphathwa kokulinganisela, kanye nokuphathwa kokuphepha.
Umsebenzi wokuphathwa kombuso weUhlelo Lokuphathwa Kwebhethri
Sifuna ukwazi ukuthi siyini isimo sebhethri, yini ivoloshi, amandla amangaki, ukuthi angakanani umthamo, futhi yini umsebenzi wokuphathwa kombuso we-BMS uzositshela impendulo. Umsebenzi oyisisekelo we-BMS ukukala futhi ulinganise amapharamitha webhethri, kufaka phakathi amapharamitha ayisisekelo nezifundazwe ezinjenge-voltage, yamanje, kanye lokushisa, kanye nokubala idatha yebhethri le-BEBATE njenge-SOC and Soh.
Ukukalwa kweseli
Ukulinganiswa Kwemininingwane Eyisisekelo: Umsebenzi oyisisekelo kakhulu wohlelo lokuphathwa kwebhethri ukukala i-voltage, yamanje, nokushisa kweseli lebhethri, okuyisisekelo sokubalwa kwezinga eliphakeme kanye nokulawula ukuqonda kwazo zonke izinhlelo zokuphatha ibhethri.
Ukutholwa kokumelana nokufakwa kwe-insulation: ohlelweni lokuphathwa kwebhethri, ukutholwa kokufakelwa kohlelo lonke lwebhethri kanye nohlelo oluphakeme lwe-voltage kuyadingeka.
Ukubalwa kwesibalo
I-SOC isho isimo sokukhokhisa, umthamo osele webhethri. Kalula nje, yikana ukuthi amandla angakanani asele ebhethri.
I-SOC iyipharamitha ebaluleke kakhulu ku-BMS, ngoba konke okunye kusekelwe ku-SOC, ngakho-ke ukunemba kwayo kubaluleke kakhulu. Uma kungekho okunembile Soc, ayikho inani lemisebenzi yokuvikela engenza umsebenzi we-BMS ngokujwayelekile, ngoba ibhethri livame ukuvikeleka, futhi impilo yebhethri ayikwazi ukunwetshwa.
Izindlela zokulinganisa ze-Maintream SoC zamanje zifaka indlela evulekile ye-Voltatage ye-Voltage, indlela yokuhlanganisa yamanje, indlela yokuhlunga yeKalman, nendlela yenethiwekhi ye-neural. Okubili kokuqala kusetshenziswa kakhulu.
Umsebenzi wokuphathwa kwebhalansi kweUhlelo Lokuphathwa Kwebhethri
Ibhethri ngalinye linobuntu bayo "ubuntu". Ukukhuluma ngebhalansi, kufanele siqale ngebhethri. Ngisho namabhethri akhiqizwa ngumenzi ofanayo ku-batch efanayo anomjikelezo wawo wempilo kanye "nobuntu" bawo "abathathwa yibhethri ngalinye ngeke bafane. Kunezinhlobo ezimbili zezizathu zalokhu kungahambelani:
Ukungahambisani nokukhiqizwa kwamaseli nokungahambisani nokuphendula nge-electrochemical
Ukukhiqizwa Okungahambelani
Ukukhishwa kokukhiqizwa kuqondwa kahle. Isibonelo, kwinqubo yokukhiqiza, ohlukanisayo, iCathode, kanye nezinto zokwenza i-anode azihambisani, okuholela ekungangenisekeni kwebhethri ngokuphelele.
Ukungahambisani kwe-electrochemical kusho ukuthi kwinqubo yokushaja kwebhethri nokukhipha, noma ngabe ukukhiqizwa kanye nokucutshungulwa kwamabhethri amabili kufana ncamashi, imvelo eshisayo ayisoze yaguquguquka ngesikhathi sokuphendula nge-electrochemical.
Siyazi ukuthi ukushaja ngokweqile kanye nokukhishwa ngokweqile kungakwenza ukulimala okukhulu kwebhethri. Ngakho-ke, lapho ibhethri b selikhokhiswa ngokuphelele lapho ishaja, noma i-SOC yebhethri B isivele iphansi kakhulu lapho ikhipha, kuyadingeka ukuvikela ukushaja b, namandla ebhethri A nebhethri C akunakusetshenziswa ngokuphelele. Lokhu kuphumela ku:
Okokuqala, umthamo wangempela osetshenziswayo wephakethe lebhethri uncishisiwe: umthamo amabhethri A no-C angawasebenzisa, kepha manje akukho mbumbulu ukuze unakekele ama-B, njengabancane kanye nezinyathelo ezinde zona zihamba kancane. Awukwazi ukwenza ama-strides amakhulu.
Okwesibili, impilo yephakethe lebhethri incishisiwe: I-Strike incane, inani lezinyathelo ezidingekayo ukuze zihambe ziningi, futhi imilenze ikhathele ngokwengeziwe; Umthamo uncishisiwe, futhi inani lemijikelezo edinga ukukhokhiswa futhi ikhishwe ukukhuphuka, futhi i-atchation yebhethri nayo inkulu. Isibonelo, iseli elilodwa lebhethri lingafinyelela imijikelezo engama-4000 ngaphansi kwesimo se-100% ukushaja kanye nokukhipha, kepha ayikwazi ukufinyelela ku-100% ekusetshenzisweni kwangempela, futhi inani lemijikelezo akumele lifinyelele ezikhathini ezingama-4000.
Kunezindlela ezimbili ezibalulekile zokulinganisa ze-BMS, ukulinganisa nje nokulinganisa okusebenzayo.
Okwamanje ukulinganiswa kokungezwani kuncane, njengokulingana okuphayona okunikezwe yi-DALY BMS, enezindawo ezilinganiselayo ze-30m-30 kanye nesikhathi eside sebhethri voltage ukulingana isikhathi.
Ukulinganisa okusebenzayo kwamanje kukhulu, njengeI-Balancer esebenzayoKuthuthukiswe yiDaly BMS, efinyelela lapho kulinganiselwa khona okulinganiselayo kwe-1A futhi inesikhathi esifushane sokulinganisa sebhethri.
Umsebenzi wokuvikelwa weUhlelo Lokuphathwa Kwebhethri
I-BMS Monitor ifana nehardware yohlelo lukagesi. Ngokusho kwezimo ezihlukile zebhethri, ihlukaniswe ngamazinga ahlukene amaphutha (amaphutha amancane, amaphutha amakhulu, amaphutha abulalayo), kanye nezinyathelo zokucubungula ezahlukahlukene zithathwa ngaphansi kwamazinga ahlukene amaphutha: Isexwayiso, umkhawulo wamandla noma ukusika ugesi ophakeme ngqo. Amaphutha afaka ukutholwa kwedatha kanye namaphutha wokulahla, amaphutha kagesi (izinzwa kanye nabasebenzayo), amaphutha okuxhumana, kanye namaphutha wesimo sebhethri.
Isibonelo esivamile ukuthi lapho ibhethri selishintshiwe, amajaji we-BMS ukuthi ibhethri ligcwele kakhulu ngokususelwa ekushiseni kwebhethri okuqoqwe, bese umjikelezo olawulwa ibhethri unqanyuliwe ukwenza ukushisa ngokweqile nokuthumela i-alamu kuma-EMS nakwezinye izinhlelo zokuphatha
