Isistimu yokuphatha ibhethri ye-BMS iyithuluzi elinamandla lokuthuthukisa ubude bempilo yamabhethri esistimu yelanga. Isistimu yokuphatha ibhethri ye-BMS iphinde isize ukuqinisekisa ukuthi amabhethri aphephile futhi anokwethenjelwa. Ngezansi kunencazelo enemininingwane yohlelo lwe-BMS kanye nezinzuzo ezitholwa abasebenzisi.
Indlela Uhlelo lwe-BMS olusebenza ngayo
I-BMS yamabhethri e-lithium isebenzisa ikhompuyutha ekhethekile nezinzwa ukuze ilawule ukuthi ibhethri lisebenza kanjani. Izinzwa zihlola izinga lokushisa, izinga lokushaja, umthamo webhethri, nokuningi. Ikhompuyutha esebhodini lesistimu ye-BMS ibe seyenza izibalo ezilawula ukushajwa nokushajwa kwebhethri. Umgomo wayo uwukuthuthukisa isikhathi sokuphila sesistimu yokugcina ibhethri yelanga ngenkathi iqinisekisa ukuthi iphephile futhi ithembekile ukusebenza.
Izingxenye Zohlelo Lokuphatha Ibhethri
Isistimu yokuphatha ibhethri ye-BMS ihlanganisa izingxenye ezimbalwa ezibalulekile ezisebenza ndawonye ukuze ilethe ukusebenza okuphelele okuvela kuphakethe lebhethri. Izingxenye yilezi:
Ishaja yebhethri
Ishaja ifaka amandla ephaketheni lebhethri ngevoltheji efanele kanye nezinga lokugeleza ukuze kuqinisekiswe ukuthi ishajwe ngokufanele.
I-Battery Monitor
Imonitha yebhethri iyisudi yezinzwa eziqapha impilo yamabhethri nolunye ulwazi olubalulekile njengesimo sokushaja nezinga lokushisa.
Isilawuli Sebhethri
Isilawuli silawula ukushajwa nokuphuma kwephakethe lebhethri. Iqinisekisa ukuthi amandla angena futhi ayishiye kahle ibhethri.
Izixhumi
Lezi zixhumi zixhuma uhlelo lwe-BMS, amabhethri, i-inverter, kanye ne-solar panel. Iqinisekisa ukuthi i-BMS ifinyelela lonke ulwazi oluvela kusistimu sonozungezilanga.
Izici Zesistimu Yokulawula Ibhethri ye-BMS
Yonke i-BMS yamabhethri e-lithium inezici zayo ezihlukile. Nokho, izici zayo ezimbili ezibaluleke kakhulu ukuvikela nokuphatha umthamo wephakethe lebhethri. Ukuvikelwa kwephakethe lebhethri kufinyelelwa ngokuqinisekisa ukuvikeleka kukagesi nokuvikelwa kokushisa.
Ukuvikelwa ngogesi kusho ukuthi uhlelo lokuphatha amabhethri luzovala uma indawo yokusebenza ephephile (SOA) yeqiwe. Ukuvikelwa kwe-thermal kungaba umthetho osebenzayo noma we-passive wezinga lokushisa ukuze ugcine ipakethi yebhethri ngaphakathi kwe-SOA yayo.
Mayelana nokuphathwa kwamandla ebhethri, i-BMS yamabhethri e-lithium yakhelwe ukukhulisa umthamo. Iphakethe lebhethri lizogcina lingasasizi uma ukuphathwa kwamandla kungenziwanga.
Isidingo sokuphathwa kwamandla ukuthi ibhethri ngalinye ephaketheni lebhethri linokusebenza okuhluke kancane. Lo mehluko wokusebenza uphawuleka kakhulu kumazinga okuvuza. Uma entsha, iphakethe lebhethri lingase lisebenze kahle kakhulu. Nokho, ngokuhamba kwesikhathi, umehluko ekusebenzeni kwamaseli ebhethri uyakhula. Ngenxa yalokho, kungaholela ekulimaleni kokusebenza. Umphumela uba izimo zokusebenza ezingaphephile zalo lonke iphakethe lebhethri.
Kafushane, isistimu yokuphatha ibhethri ye-BMS izosusa ukushajwa kumaseli ashajwe kakhulu, okuvimbela ukushajwa ngokweqile. Iphinde ivumele amaseli ashajwe kancane ukuthi athole ukushaja kwamanje.
I-BMS yamabhethri e-lithium izophinda iqondise kabusha amanye noma cishe wonke amandla okushaja azungeze amaseli ashajiwe. Ngenxa yalokho, amaseli ashajwe kancane athola amandla okushaja isikhathi eside.
Ngaphandle kwesistimu yokuphatha ibhethri ye-BMS, amaseli ashaja kuqala azoqhubeka nokushaja, okungaholela ekushiseni ngokweqile. Ngenkathi amabhethri e-lithium enikeza ukusebenza okuhle kakhulu, anenkinga ngokushisa ngokweqile lapho kulethwa amandla angaphezulu. Ukushisa ngokweqile ibhethri ye-lithium kwehlisa kakhulu ukusebenza kwayo. Esimeni esibi kakhulu, kungaholela ekuhlulekeni kwalo lonke iphakethe lebhethri.
Izinhlobo ze-BMS zamabhethri e-Lithium
Amasistimu okuphatha ibhethri angaba lula noma abe nzima kakhulu ezimweni ezihlukene zokusetshenziswa nobuchwepheshe. Nokho, zonke zihlose ukunakekela iphakethe lebhethri. Izigaba ezivame kakhulu yilezi:
I-Centralized BMS Systems
I-BMS emaphakathi yamabhethri e-lithium isebenzisa isistimu yokuphatha ibhethri ye-BMS eyodwa kuphakethe lebhethri. Wonke amabhethri axhunywe ngqo kwi-BMS. Inzuzo enkulu yalolu hlelo ukuthi ihlangene. Ukwengeza, iyathengeka kakhulu.
Ububi bayo obukhulu ukuthi njengoba wonke amabhethri exhumeka kuyunithi ye-BMS ngokuqondile, kudinga izimbobo eziningi ukuxhuma kuphakethe lebhethri. Umphumela uba izintambo eziningi, izixhumi, namakhebula. Ephaketheni elikhulu lebhethri, lokhu kungenza kube nzima ukulungisa nokuxazulula inkinga.
I-BMS ye-Modular yamabhethri e-Lithium
Njenge-BMS ephakathi nendawo, isistimu ye-modular ixhunywe engxenyeni ezinikele yephakethe lebhethri. Amayunithi emojuli ye-BMS kwesinye isikhathi axhunywa kumojuli eyinhloko eqapha ukusebenza kwawo. Inzuzo enkulu ukuthi ukuxazulula izinkinga nokugcinwa kulula. Kodwa-ke, okubi ukuthi isistimu yokuphatha ibhethri ye-modular ibiza ngaphezulu.
Amasistimu e-BMS asebenzayo
Isistimu yokuphatha ibhethri ye-BMS esebenzayo iqapha umthamo webhethri wephakethe, lamanje, kanye nomthamo. Isebenzisa lolu lwazi ukuze ilawule ukushajwa nokushajwa kwesistimu ukuze iqinisekise ukuthi iphekhi yebhethri iphephile ukuthi ingasebenza futhi ikwenza lokho kumazinga afanele.
I-Passive BMS Systems
I-BMS engenzi lutho yamabhethri e-lithium ngeke igade amanje kanye ne-voltage. Kunalokho, incike esibali sikhathi esilula ukuze ilawule ukushajwa nezinga lokukhishwa kwephakethe lebhethri. Nakuba kuwuhlelo olungasebenzi kahle, kubiza kancane kakhulu ukuluthola.
Izinzuzo Zokusebenzisa Isistimu Yokulawula Ibhethri ye-BMS
Isistimu yokugcina ibhethri ingabandakanya ambalwa noma amakhulu amabhethri e-lithium. Isistimu enjalo yokugcina ibhethri ingaba nesilinganiso se-voltage esingafika ku-800V kanye nesimanje esingu-300A noma ngaphezulu.
Ukungaphathi kahle iphakethe lamandla kagesi aphezulu kungaholela ezinhlekeleleni ezimbi. Kanjalo, ukufaka isistimu yokuphatha ibhethri ye-BMS kubalulekile ukuze usebenzise iphakethe lebhethri ngokuphepha. Izinzuzo eziyinhloko ze-BMS zamabhethri e-lithium zingashiwo kanje:
Ukusebenza Okuphephile
Kubalulekile ukuqinisekisa ukusebenza okuphephile kwephakethe lebhethri elinosayizi omaphakathi noma elikhulu. Kodwa-ke, ngisho namayunithi amancane afana namafoni aziwa ngokubamba umlilo uma isistimu yokuphatha ibhethri efanele ingafakiwe.
Ukwethenjwa Okuthuthukisiwe Nesikhathi Sokuphila
Uhlelo lokuphatha ibhethri luqinisekisa ukuthi amaseli angaphakathi kwephakethe lebhethri asetshenziswa ngaphakathi kwemingcele yokusebenza ephephile. Umphumela uba ukuthi amabhethri avikelwe ekushajweni okunolaka nasekukhishweni, okuholela esimisweni sonozungezilanga esithembekile esinganikeza iminyaka yenkonzo ethembekile.
Ibanga elikhulu nokusebenza
I-BMS isiza ukuphatha umthamo wamayunithi angawodwana kuphakethe lebhethri. Iqinisekisa ukuthi umthamo wephakethe webhethri uyatholakala. I-BMS ilandisa ngokuhlukahluka kokuzikhipha ngokwakho, izinga lokushisa, kanye nokuncipha okuvamile, okungenza iphakethe lebhethri lingasebenzi uma lingalawulwa.
Ukuxilonga kanye Nokuxhumana Kwangaphandle
I-BMS ivumela ukuqapha okuqhubekayo, ngesikhathi sangempela kwephakethe lebhethri. Ngokusekelwe ekusetshenzisweni kwamanje, inikeza izilinganiso ezinokwethenjelwa zempilo yebhethri nempilo elindelekile. Ulwazi lokuxilonga olunikeziwe luphinde luqinisekise ukuthi noma iyiphi inkinga enkulu itholwa kusenesikhathi ngaphambi kokuba ibe yinhlekelele. Ngokombono wezezimali, kungasiza ekuqinisekiseni ukuhlelwa okufanele kokushintshwa kwephakethe.
Izindleko Ezincishisiwe Esikhathini Eside
I-BMS iza nezindleko zokuqala eziphezulu ngaphezu kwezindleko eziphezulu zephakethe lebhethri elisha. Nokho, ukugada okuwumphumela, nokuvikelwa okunikezwa yi-BMS, kuqinisekisa izindleko ezincishisiwe esikhathini eside.
Isifinyezo
Isistimu yokuphatha ibhethri ye-BMS iyithuluzi elinamandla nelisebenza ngempumelelo elingasiza abanikazi besistimu yelanga baqonde ukuthi ibhange labo lebhethri lisebenza kanjani. Kungasiza futhi ukwenza izinqumo eziphusile zezezimali ngenkathi ithuthukisa ukuphepha kwephakethe lebhethri, ukuphila isikhathi eside, nokwethembeka. Umphumela uba ukuthi abanikazi be-BMS yamabhethri e-lithium bathola okuningi emalini yabo.
