Njengoba izindaba zamandla zigqama kakhulu, ukusetshenziswa nokukhuthazwa kwemithombo yamandla avuselelekayo kubonakala njengendlela ebalulekile yokuphuma. Njengamanje, ubuchwepheshe bokugcina amandla buyisihloko esishisayo kulo mkhakha njengoba bungasebenzisa ubuchwepheshe obufana namabhethri ensimbi, ama-supercapacitor namabhethri agelezayo kanye namandla avuselelekayo.
Njengengxenye ebaluleke kakhulu kuisistimu yokugcina amandla (ESS) , indima yamabhethri ibalulekile, ikakhulukazi uma isetshenziswa ezinhlelweni zikagesi ezingasebenzisa amandla kagesi ngendlela ephumelela kakhudlwana. Phakathi kwedizayini yesistimu yokugcina ibhethri,uhlelo lokuphatha ibhethri (BMS) isebenza njengobuchopho nomnakekeli, iqinisekisa ukuphepha, ukusebenza kahle, nokuphila isikhathi eside kwalo lonke uhlelo. Kulesi sihloko, sizocubungula ukubaluleka kwe-BMS ku-ESS futhi sihlole imisebenzi yayo enezici eziningi eziyenza ibe yingxenye ebalulekile yempumelelo yanoma yimuphi umzamo wokugcina amandla.
Ukuqonda i-BMS ku-ESS:
I-BMS iyisistimu engaphansi esetshenziselwa ukuphatha isistimu yokugcina ibhethri, iqapha amapharamitha njengokushajwa kwebhethri nokushajwa, izinga lokushisa, i-voltage, i-SOC (State of Charge), i-SOH (Isimo Sezempilo), kanye nezinyathelo zokuvikela. Izinjongo eziyinhloko ze-BMS yilezi: okokuqala, ukuqapha isimo sebhethri ukuze kutholwe ukungahambi kahle ngesikhathi futhi kuthathwe izinyathelo ezifanele; okwesibili, ukulawula inqubo yokushaja nokushajwa ukuze kuqinisekiswe ukuthi ibhethri liyashajwa futhi likhishwa endaweni ephephile futhi kuncishiswe umonakalo nokuguga; ngesikhathi esifanayo, kuyadingeka ukwenza ukulinganisa kwebhethri, okungukuthi, ukugcina ukuvumelana kokusebenza kwebhethri ngokulungisa umehluko wokushaja phakathi komuntu ngamunye kuphakethe lebhethri; ngaphezu kwalokho, i-BMS yokugcina amandla nayo idinga ukuhlonyiswa ngemisebenzi yokuxhumana ukuze ivumele imisebenzi efana nokusebenzisana kwedatha nokulawula kude nezinye izinhlelo.
Imisebenzi eminingi ye-BMS:
1. Ukuqapha nokulawula isimo sebhethri: I-BMS yokugcina amandla ingaqapha imingcele yebhethri efana ne-voltage, yamanje, izinga lokushisa, i-SOC ne-SOH, kanye nolunye ulwazi mayelana nebhethri. Lokhu ikwenza ngokusebenzisa izinzwa ukuqoqa idatha yebhethri.
2. Ukulinganisa kwe-SOC (Isimo Sokushaja): Ngesikhathi sokusebenzisa amaphakethe ebhethri, kuvame ukuba nokungalingani ku-SOC yamabhethri, okubangela ukuthi ukusebenza kwephakethe lebhethri kwehle noma kuholele ekuhlulekeni kwebhethri. I-Energy Storage BMS ingaxazulula le nkinga ngokusebenzisa ubuchwepheshe bokulinganisa ibhethri, okungukuthi, ukulawula ukuphuma nokushajwa phakathi kwamabhethri ukuze i-SOC yebhethri ngayinye ihlale ifana. Ukulinganisa kuncike ekutheni amandla ebhethri ahlakaziwe noma adluliswa phakathi kwamabhethri futhi angahlukaniswa abe amamodi amabili: ukulinganisa okwenziwayo kanye nokulingana okusebenzayo.
3. Ukuvimbela ukushajwa ngokweqile noma ukuchichima ngokweqile: Ukushajwa ngokweqile noma ukuchichima ngokweqile amabhethri kuyinkinga engase yenzeke ngephakethe lebhethri, izonciphisa umthamo wephakethe lebhethri noma ize ilenze lingakwazi ukusetshenziswa. Ngakho, i-BMS yokugcina amandla isetshenziselwa ukulawula amandla kagesi ebhethri ngesikhathi sokushaja ukuze kuqinisekiswe isimo sesikhathi sangempela sebhethri nokumisa ukushaja lapho ibhethri selifinyelele umthamo walo omkhulu.
4. Qinisekisa ukuqapha okukude nokwethusa kwesistimu: I-BMS yokugcina amandla ingadlulisela idatha ngenethiwekhi engenantambo nezinye izindlela futhi ithumele idatha yesikhathi sangempela kutheminali yokuqapha, futhi ngesikhathi esifanayo, ingathumela ukutholwa kwamaphutha kanye nolwazi lwe-alamu ngezikhathi ezithile. ngokuvumelana nezilungiselelo zesistimu. I-BMS iphinde isekele amathuluzi okubika nokuhlaziya avumelana nezimo angakhiqiza idatha yomlando namarekhodi omcimbi webhethri nesistimu ukusekela ukuqapha idatha kanye nokuhlonzwa kwamaphutha.
5. Nikeza imisebenzi eminingi yokuvikela: I-BMS yokulondoloza amandla ingahlinzeka ngemisebenzi yokuvikela ehlukahlukene ukuze kuvinjelwe izinkinga ezifana nokunqamuka kwebhethri nokudlula isikhathi eside, kanye nokuqinisekisa ukuxhumana okuphephile phakathi kwezingxenye zebhethri. Ngesikhathi esifanayo, ingakwazi futhi ukubona futhi isingathe izingozi ezifana nokuhluleka kweyunithi kanye nokwehluleka kwephuzu elilodwa.
6. Ukulawulwa kwezinga lokushisa lebhethri: Izinga lokushisa lebhethri lingenye yezinto ezibaluleke kakhulu ezithinta ukusebenza kwebhethri nempilo. I-BMS yokugcina amandla ingaqapha izinga lokushisa lebhethri futhi ithathe izinyathelo ezisebenzayo zokulawula izinga lokushisa lebhethri ukuvimbela izinga lokushisa lingabi phezulu kakhulu noma lehle kakhulu ukuthi lidale umonakalo ebhethri.
Empeleni, i-BMS yokugcina amandla isebenza njengobuchopho nomnakekeli wesistimu yokugcina amandla. Ingahlinzeka ngokuqapha okuphelele nokulawula izinhlelo zokugcina ibhethri ukuze kuqinisekiswe ukuphepha kwazo, ukuzinza nokusebenza kwazo, ngaleyo ndlela kutholakale imiphumela engcono kakhulu evela ku-ESS. Ngaphezu kwalokho, i-BMS ingathuthukisa isikhathi sokuphila nokuthembeka kwe-ESS, inciphise izindleko zokunakekela kanye nezingozi zokusebenza, futhi inikeze isisombululo sokugcina amandla esiguquguqukayo nesinokwethenjelwa.
