Uhlelo lokuphathwa kwebhethri lwe-BMS luyithuluzi elinamandla lokuthuthukisa isikhathi sokuphila samabhethri ohlelo lwelanga. Uhlelo lokuphathwa kwebhethri lwe-BMS lusiza ekuqinisekiseni ukuthi amabhethri aphephile futhi athembekile. Ngezansi kwencazelo eningiliziwe yohlelo lwe-BMS kanye nabasebenzisi bezinzuzo abatholayo.
Kusebenza kanjani uhlelo lwe-BMS
I-BMS yamabhethri e-lithium isebenzisa ikhompyutha ekhethekile nezinzwa zokulawula ukuthi ibhethri lisebenza kanjani. Ukuhlolwa kwezinzwa kokushisa, izinga lokushaja, umthamo webhethri, nokuningi. Ikhompyutha ebhodini le-BMS uhlelo lwe-BMS bese lwenza ukubalwa okulawula ukushaja kanye nokukhipha ibhethri. Umgomo wayo ukuthuthukisa isikhathi sokuphila sohlelo lokugcina ibhethri ngenkathi uqinisekisa ukuthi kuphephile futhi kuthembekile ukusebenza.
Izingxenye zohlelo lokuphatha ibhethri
Uhlelo lokuphathwa kwebhethri lwe-BMS lunezinto ezimbalwa ezibalulekile ezisebenza ndawonye ukuletha ukusebenza kahle kwiphakethe lebhethri. Izakhi yilezi:
Ishaja yebhethri
Ishaja liphakela amandla epakethe lebhethri ku-voltage efanelekile kanye ne-flow rate ukuze uqinisekise ukuthi ikhokhiswe kahle.
Ukuqapha ibhethri
Ibhethri Monitor yisulu lezinzwa ezibhekisisa impilo yebhethri kanye neminye imininingwane ebalulekile efana nesimo sokushaja kanye nokushisa.
Isilawuli sebhethri
Isilawuli siphatha imali ekhokhwayo nokukhishwa kwephakethe lebhethri. Kuqinisekisa ukuthi amandla angena futhi ashiye iphakethe lebhethri kahle.
Izixhumi
Lezi zixhumi zixhuma uhlelo lwe-BMS, amabhethri, i-inverter, nephaneli yelanga. Kuqinisekisa ukuthi i-BMS ithola lonke ulwazi oluvela ohlelweni lwelanga.
Izici zohlelo lokuphathwa kwebhethri lwe-BMS
Njalo ama-BMS amabhethri e-lithium anezici zayo ezihlukile. Kodwa-ke, izici zayo ezimbili ezibaluleke kakhulu ziyavikela futhi zilawula umthamo wephakethe lebhethri. Ukuvikelwa kwebhethri yebhethri kutholakala ngokuqinisekisa ukuvikelwa kagesi nokuvikelwa okushisayo.
Ukuvikelwa kukagesi kusho ukuthi uhlelo lokuphatha ibhethri luzovala uma indawo ephephile yokusebenza (i-SOA) idluliwe. Ukuvikelwa okushisayo kungaba yithuluzi lokushisa elisebenzayo noma lokufanisa ukugcina iphakethe lebhethri ngaphakathi kwe-soa yalo.
Mayelana nokuphathwa kwamandla ebhethri, i-BMS yamabhethri e-lithium yenzelwe ukukhulisa umthamo. Iphakethe lebhethri ekugcineni lizobe lingenamsebenzi uma ukuphathwa kwamandla kungenziwa.
Isidingo sokuphathwa kwamandla ukuthi ibhethri ngalinye ephaketheni lebhethri lisebenza ngokuhlukile. Lokhu kuhluka kokusebenza kubaluleke kakhulu kumanani avuzayo. Lapho okusha, iphakethe lebhethri lingase lenze kahle. Kodwa-ke, ngokuhamba kwesikhathi, umehluko ekusebenzeni kwebhethri kweseli. Ngenxa yalokho, kungaholela ekulimaleni kokusebenza. Umphumela uyisimo sokusebenza esingaphephile kuyo yonke ipakethe lebhethri.
Ngamafuphi, uhlelo lokuphathwa kwebhethri lwe-BMS luzosusa imali ekhokhwayo kumaseli akhokhisiwe kakhulu, avimbela ukugcwala ngokweqile. Iphinde ivumele amangqamuzana amancane akhokhisiwe ukuthola ukushaja okwengeziwe kwamanje.
I-BMS yamabhethri e-lithium nawo azophinda aqondise amanye noma cishe wonke ama-charging akhona azungeze amaseli akhokhisiwe. Ngenxa yalokho, amangqamuzana amancane akhokhisiwe athola ukushaja okwamanje isikhathi eside.
Ngaphandle kohlelo lokuphathwa kwebhethri lwe-BMS, amaseli azoqhubeka azoqhubeka nokukhokhisa, okungaholela ekushiseni ngokweqile. Ngenkathi amabhethri e-lithium anikeza ukusebenza okuhle kakhulu, anenkinga ngokushisa ngokweqile lapho kuthunyelwa okwedlulele ngokweqile. Ukushisa ngokweqile ibhethri le-lithium lilimaza kakhulu ukusebenza kwalo. Esimweni esibi kakhulu, kungaholela ekwehlulekeni kwalo lonke ipakethe lebhethri.
Izinhlobo ze-BMS zamabhethri e-lithium
Izinhlelo zokuphathwa kwebhethri zingaba lula noma ziyinkimbinkimbi kakhulu ngamacala ahlukile okusetshenziswa nobuchwepheshe. Kodwa-ke, bonke bahlose ukunakekela iphakethe lebhethri. Izigaba ezivame kakhulu yilezi:
Amasistimu we-BMS aphakathi
I-BMS emaphakathi yamabhethri e-lithium asebenzisa uhlelo olulodwa lwebhethri lwebhethri lokuphathwa kwebhethri. Wonke amabhethri axhumeke ngqo kwi-BMS. Inzuzo enkulu yalolu hlelo ukuthi icwecwe. Ngokwengeziwe, kuyabiza kakhulu.
I-MAID ephansi yayo ukuthi njengoba wonke amabhethri axhumeka kwiyunithi ye-BMS ngqo, kudinga amachweba amaningi ukuxhuma kwiphakethe lebhethri. Umphumela uba izintambo eziningi, izixhumi, kanye nokubhekelwa. Ephaketheni elikhulu lebhethri, lokhu kungaqinisa ukulungiswa okunzima nokuxazulula inkinga.
Ama-bms ajwayelekile amabhethri e-lithium
Njenge-BMS emaphakathi, uhlelo lwe-modular luxhumeke engxenyeni enikezelwe yephakethe lebhethri. Amayunithi we-module BMS kwesinye isikhathi axhumeke kwimodyuli eyinhloko ebheka ukusebenza kwawo. Inzuzo enkulu ukuthi ukuxazulula inkinga kanye nokunakekelwa kwenziwa lula. Kodwa-ke, okuphansi ukuthi uhlelo lokuphatha ibhethri lubiza ngaphezulu.
Izinhlelo ezisebenzayo ze-BMS
Uhlelo olusebenzayo lokuphathwa kwebhethri lwe-BMS luqapha ama-voltage ebhethri, okwamanje, kanye namandla. Isebenzisa lolu lwazi ukulawula ukushaja kanye nokukhipha uhlelo ukuze kuqinisekiswe ukuthi iphakethe lebhethri liphephile ukusebenza futhi likwenza lokho ngamazinga afanele.
Izinhlelo ze-BMS ezenzakalisayo
I-BMS yokuphambuka yamabhethri e-lithium ngeke aqaphe amanje namandla kagesi. Esikhundleni salokho, kuncike ku-timer elula ukulawula inani lokushaja kanye nokuphuma kwephakethe lebhethri. Ngenkathi uhlelo olusebenzayo olusebenza kahle, lubiza kakhulu ukuze lutholakale.
Izinzuzo zokusebenzisa uhlelo lokuphathwa kwebhethri lwe-BMS
Uhlelo lokulondolozwa kwebhethri lungahlanganisa olumbalwa noma lwamakhulu amabhethri e-lithium. Uhlelo olunjalo lokugcina ibhethri lungaba nesilinganiso se-voltage esifinyelela ku-800V naku-300a noma ngaphezulu.
Ukuphazamiseka okulindile kwephakethe eliphakeme kangaka kungaholela ezinhlekeleleni ezinkulu. Ngokunjalo, ukufaka uhlelo lokuphathwa kwebhethri lwe-BMS kubalulekile ukusebenzisa iphakethe lebhethri ngokuphepha. Izinzuzo eziphambili ze-BMS zamabhethri e-lithium zingachazwa kanjena:
Ukusebenza okuphephile
Kubalulekile ukuqinisekisa ukusebenza okuphephile kwepakethe lebhethri eliphakathi nendawo noma elikhulu. Kodwa-ke, ngisho namayunithi amancane afana nezingcingo ezaziwa ngokuthi zibambe umlilo uma uhlelo olufanele lokuphathwa kwebhethri lungafakwanga.
Ukwethembeka okuthuthukisiwe kanye nokuphila
Uhlelo lokuphathwa kwebhethri luqinisekisa ukuthi amaseli ngaphakathi kwephakethe lebhethri asetshenziswa ngaphakathi kwamapharamitha okusebenza aphephile. Umphumela uba ukuthi amabhethri avikelekile ekushaja okunolaka nangokwehla, okuholela ohlelweni oluthembekile olungahlinzeka ngeminyaka yesevisi ethembekile.
Uhla olukhulu nokusebenza
I-BMS isiza ukuphatha umthamo wamayunithi ngamanye ephaketheni lebhethri. Kuqinisekisa ukuthi umthamo wephakethe webhethri ofanele uyatholakala. I-Akhawunti ye-BMS yokuhlukahluka ekuzithekuzeleni, okushisa, kanye nokuheha okujwayelekile, okungakhipha iphakethe lebhethri okungenamsebenzi uma kungalawulwa.
Ukuxilonga nokuxhumana kwangaphandle
I-BMS ivumela ukuqapha okuqhubekayo, kwangempela kwesikhathi sephakethe lebhethri. Ngokusekelwe ekusetshenzisweni kwamanje, ihlinzeka ngezilinganiso ezithembekile zezempilo yebhethri kanye nesikhathi esilindelekile sokuphila. Imininingwane yokuxilonga enikeziwe ibuye iqinisekise ukuthi noma yiluphi udaba olukhulu lutholwa kusenesikhathi ngaphambi kokuba liphenduke eliyingozi. Ngokombono wezezimali, kungasiza ekuqinisekiseni ukuhlelwa okufanele kokufakwa esikhundleni kwephakethe.
Izindleko ezincishisiwe ngesikhathi eside
I-BMS iza nezindleko eziphezulu zokuqala ngaphezulu kwezindleko eziphakeme zephakethe lebhethri elisha. Kodwa-ke, ukwengamela okuholela, nokuvikelwa okunikezwa yi-BMS, kuqinisekisa izindleko ezincishisiwe ngesikhathi eside.
Ukubeka kafushane
Uhlelo lokuphathwa kwebhethri lwe-BMS luyithuluzi elinamandla futhi elisebenzayo elingasiza abanikazi besistimu yelanga baqonde ukuthi ibhange labo lebhethri lisebenza kanjani. Kungasiza futhi ukwenza izinqumo ezinezezimali ezinezezimali ngenkathi kuthuthukisa ukuphepha kwebhethri, isikhathi eside, kanye nokwethenjwa. Umphumela uba ukuthi abanikazi be-BMS yamabhethri e-lithium bathola okuningi ngemali yabo.
