Iyini uhlelo lokuphatha ibhethri (i-BMS)?
Igama eliphelele likaI-BMSUhlelo Lokuphathwa Kwebhethri, uhlelo lokuphathwa kwebhethri. Luyidivayisi ebambisana nokuqapha isimo sebhethri lokugcina amandla. Ihloselwe kakhulu ukuphathwa nokugcinwa okuhlakaniphile kweyunithi ngayinye yebhethri, ukuvimbela ibhethri ekushajeni ngokweqile nasekukhipheni ngokweqile, ukwandisa impilo yebhethri, nokuqapha isimo sebhethri. Ngokuvamile, i-BMS imelelwa njengebhodi lesifunda noma ibhokisi lehadiwe.
I-BMS ingenye yezinhlelo eziyinhloko zesistimu yokugcina amandla ebhethri. Inesibopho sokuqapha isimo sokusebenza kwebhethri ngalinye kuisitoreji samandla ebhethriukuqinisekisa ukusebenza okuphephile nokuthembekile kweyunithi yokugcina amandla. I-BMS ingaqapha futhi iqoqe amapharamitha esimo sebhethri lokugcina amandla ngesikhathi sangempela (kufaka phakathi kodwa kungagcini ku-voltage yebhethri elilodwa, izinga lokushisa lepali yebhethri, ugesi wesekethe yebhethri, i-voltage yokugcina yephakethe lebhethri, ukumelana kokushisa kohlelo lwebhethri, njll.), futhi yenze kudingeke Ngokusho kokuhlaziywa nokubalwa kohlelo, kutholakala amapharamitha amaningi okuhlola isimo sesistimu, kanye nokulawulwa okusebenzayo kweibhethri lokugcina amandlaumzimba uqalwa ngokwesu elithile lokulawula ukuvikelwa, ukuze kuqinisekiswe ukusebenza okuphephile nokuthembekile kweyunithi yokugcina amandla ebhethri yonke. Ngesikhathi esifanayo, i-BMS ingashintshanisa ulwazi neminye imishini yangaphandle (i-PCS, i-EMS, uhlelo lokuvikela umlilo, njll.) ngokusebenzisa isikhombimsebenzisi sayo sokuxhumana, okokufaka kwe-analog/digital, kanye nesikhombimsebenzisi sokufaka, futhi yakhe ukulawula ukuxhumana kwezinhlelo ezahlukene ezingaphansi kwesiteshi sonke samandla okugcina amandla ukuqinisekisa ukuphepha nokuthembeka kwesiteshi samandla, Ukusebenza okuxhumene negridi okusebenzayo.
Uyini umsebenzi weI-BMS?
Kunemisebenzi eminingi ye-BMS, futhi ebaluleke kakhulu, esikhathazeke kakhulu ngayo, ayilutho ngaphandle kwezici ezintathu: ukuphathwa kwesimo, ukuphathwa kwebhalansi, kanye nokuphathwa kokuphepha.
Umsebenzi wokuphatha umbuso weuhlelo lokuphatha ibhethri
Sifuna ukwazi ukuthi siyini isimo sebhethri, iyini i-voltage, ingakanani amandla, umthamo ongakanani, nokuthi iyini i-charge kanye ne-discharge current, futhi umsebenzi wokuphatha isimo se-BMS uzositshela impendulo. Umsebenzi oyisisekelo we-BMS ukukala nokulinganisa amapharamitha ebhethri, kufaka phakathi amapharamitha ayisisekelo kanye nezimo ezifana ne-voltage, i-current, kanye ne-temperature, kanye nokubalwa kwedatha yesimo sebhethri njenge-SOC kanye ne-SOH.
Ukulinganiswa kweseli
Ukulinganisa ulwazi oluyisisekelo: Umsebenzi oyisisekelo kakhulu wohlelo lokuphatha ibhethri ukukala i-voltage, i-current, kanye nezinga lokushisa leseli lebhethri, okuyisisekelo sokubala kwezinga eliphezulu kanye ne-logic yokulawula yazo zonke izinhlelo zokuphatha ibhethri.
Ukutholwa kokumelana nokushisa: Kuhlelo lokuphathwa kwebhethri, kudingeka ukutholwa kokushisa kohlelo lonke lwebhethri kanye nohlelo olunamandla aphezulu.
Ukubalwa kwe-SOC
I-SOC ibhekisela ku-State of Charge, umthamo osele webhethri. Kalula nje, ukuthi kusele amandla angakanani ebhethri.
I-SOC iyipharamitha ebaluleke kakhulu ku-BMS, ngoba konke okunye kusekelwe ku-SOC, ngakho-ke ukunemba kwayo kubaluleke kakhulu. Uma kungekho i-SOC enembile, akukho misebenzi yokuvikela engenza i-BMS isebenze ngendlela evamile, ngoba ibhethri livame ukuvikelwa, futhi isikhathi sokuphila kwebhethri asikwazi ukwelulwa.
Izindlela zokulinganisa ze-SOC ezisetshenziswa kakhulu njengamanje zifaka phakathi indlela ye-open circuit voltage, indlela yokuhlanganisa yamanje, indlela yokuhlunga ye-Kalman, kanye nendlela yenethiwekhi ye-neural. Ezimbili zokuqala zivame ukusetshenziswa.
Umsebenzi wokuphatha ibhalansi we-uhlelo lokuphatha ibhethri
Ibhethri ngalinye "linesimo salo". Ukuze sikhulume ngokulinganisela, kufanele siqale ngebhethri. Ngisho namabhethri akhiqizwa umenzi ofanayo eqenjini elifanayo anomjikelezo wawo wokuphila kanye "nobuntu" bawo - amandla ebhethri ngalinye awakwazi ukufana ncamashi. Kunezinhlobo ezimbili zezizathu zalokhu kungahambisani:
Ukungahambisani ekukhiqizweni kwamaseli kanye nokungahambisani ekuphenduleni kwe-electrochemical
ukungaguquguquki kokukhiqiza
Ukungahambisani komkhiqizo kuyaqondakala kahle. Isibonelo, enqubweni yokukhiqiza, isihlukanisi, i-cathode, kanye nezinto ze-anode azihambisani, okuholela ekungahambelani komthamo webhethri iyonke.
Ukungahambisani kwe-electrochemical kusho ukuthi enkambisweni yokushaja nokukhipha ibhethri, noma ngabe ukukhiqizwa nokucubungula kwamabhethri amabili kufana ncamashi, indawo yokushisa ayikwazi ukuhambisana ngesikhathi sokusabela kwe-electrochemical.
Siyazi ukuthi ukushaja ngokweqile nokukhipha amandla ngokweqile kungenza umonakalo omkhulu ebhethrini. Ngakho-ke, uma ibhethri B lishaja ngokugcwele lapho lishaja, noma i-SOC yebhethri B isivele iphansi kakhulu lapho likhipha amandla, kuyadingeka ukuyeka ukushaja nokukhipha amandla ukuze kuvikelwe ibhethri B, futhi amandla ebhethri A nebhethri C awakwazi ukusetshenziswa ngokugcwele. Lokhu kuphumela ku:
Okokuqala, amandla angempela angasetshenziswa ebhethri ancishisiwe: amandla angasetshenziswa amabhethri u-A no-C, kodwa manje akusekho ndawo yokusebenzisa amandla okunakekela u-B, njengoba nje abantu ababili nemilenze emithathu bebopha ubude nobude ndawonye, futhi izinyathelo zomuntu omude zihamba kancane. Awukwazi ukuthatha izinyathelo ezinkulu.
Okwesibili, impilo yebhethri iyancipha: igxathu lincane, inani lezinyathelo ezidingekayo ukuhamba liningi, futhi imilenze ikhathele kakhulu; umthamo uyancipha, futhi inani lemijikelezo edinga ukushajwa nokukhishwa liyakhula, futhi ukuncishiswa kwebhethri nakho kukhulu. Isibonelo, iseli elilodwa lebhethri lingafinyelela imijikelezo engu-4000 ngaphansi kwesimo sokushaja nokukhishwa okungu-100%, kodwa alikwazi ukufinyelela ku-100% ekusetshenzisweni kwangempela, futhi inani lemijikelezo akumele lifinyelele izikhathi ezingu-4000.
Kunezindlela ezimbili eziyinhloko zokulinganisa ze-BMS, ukulinganisela okungasebenzi kanye nokulinganisela okusebenzayo.
Ugesi wokulinganisa okwenziwa ngaphandle uncane kakhulu, njengokulinganisa okwenziwa ngaphandle okuhlinzekwa yi-DALY BMS, enogesi olinganiselayo ongu-30mA kuphela kanye nesikhathi eside sokulinganisa i-voltage yebhethri.
Umsinga wokulinganisela osebenzayo mkhulu kakhulu, njenge-ibhalansi esebenzayoyathuthukiswa yi-DALY BMS, efinyelela umugqa wokulinganisa ongu-1A futhi inesikhathi esifushane sokulinganisa i-voltage yebhethri.
Umsebenzi wokuvikela weuhlelo lokuphatha ibhethri
Isikrini se-BMS sifana nehadiwe yesistimu kagesi. Ngokwezimo zokusebenza ezahlukene zebhethri, ihlukaniswe ngamazinga ahlukene ephutha (amaphutha amancane, amaphutha amakhulu, amaphutha abulalayo), futhi kuthathwa izinyathelo ezahlukene zokucubungula ngaphansi kwamazinga ahlukene ephutha: isixwayiso, umkhawulo wamandla noma ukunqamula i-voltage ephezulu ngqo. Amaphutha afaka phakathi ukutholwa kwedatha kanye namaphutha okunokwenzeka, amaphutha kagesi (izinzwa nama-actuator), amaphutha okuxhumana, kanye namaphutha esimo sebhethri.
Isibonelo esivamile ukuthi uma ibhethri lishiswa kakhulu, i-BMS iyahlulela ukuthi ibhethri lishiswa kakhulu ngokusekelwe ekushiseni kwebhethri okuqoqiwe, bese isekethe elawula ibhethri inqanyulwa ukuze yenze ukuvikelwa kokushisa ngokweqile futhi ithumele i-alamu ku-EMS nakwezinye izinhlelo zokuphatha.
Kungani kufanele ukhethe i-DALY BMS?
I-DALY BMS, ingenye yabakhiqizi abakhulu kakhulu besistimu yokuphatha amabhethri (i-BMS) eShayina, inabasebenzi abangaphezu kuka-800, indawo yokukhiqiza engamamitha-skwele angu-20,000 kanye nonjiniyela be-R&D abangaphezu kwe-100. Imikhiqizo evela ku-Daly ithunyelwa emazweni nasezifundeni ezingaphezu kuka-150.
Umsebenzi wokuvikela ukuphepha kochwepheshe
Ibhodi elihlakaniphile kanye nebhodi lehadiwe liqukethe imisebenzi yokuvikela emikhulu eyi-6:
Ukuvikelwa kokushaja ngokweqile: Lapho i-voltage yeseli yebhethri noma i-voltage yephakethe lebhethri ifinyelela ezingeni lokuqala le-voltage yokushaja ngokweqile, kuzokhishwa umyalezo wesexwayiso, futhi lapho i-voltage ifinyelela ezingeni lesibili le-voltage yokushaja ngokweqile, i-DALY BMS izonqamula ngokuzenzakalelayo ukunikezwa kwamandla.
