Njengoko imiba yamandla ibonakala ngakumbi, ukusetyenziswa kunye nokukhuthazwa kwemithombo yamandla ahlaziyekayo kubonwa njengendlela ebalulekileyo yokuphuma.Okwangoku, iteknoloji yokugcina amandla ngumxholo oshushu kwintsimi njengoko inokusebenzisa iteknoloji efana neebhetri zetsimbi, ii-supercapacitors kunye neebhetri zokuhamba kunye namandla avuselelekayo.
Njengeyona nxalenye ibalulekileyo kwiinkqubo yokugcina amandla (ESS), indima yeebhetri ibalulekile, ngakumbi xa isetyenziswa kwiinkqubo zamandla ezinokusebenzisa amandla ombane ngokufanelekileyo.Phakathi koyilo lwenkqubo yokugcina ibhetri,inkqubo yolawulo lwebhetri (BMS)isebenza njengengqondo kunye nomgcini, iqinisekisa ukhuseleko, ukusebenza kakuhle, kunye nokuphila ixesha elide kwenkqubo yonke.Kweli nqaku, siza kuhlolisisa ukubaluleka kwe-BMS kwi-ESS kwaye sihlolisise imisebenzi yayo eneenkalo ezininzi ezenza ukuba ibe yinto ebalulekileyo kwimpumelelo yayo nayiphi na into yokugcina amandla.
Ukuqonda i-BMS kwi-ESS:
I-BMS i-subsystem esetyenziselwa ukulawula inkqubo yokugcina ibhetri, ibeka iliso kwiiparameters ezifana nokutshaja ibhetri kunye nokukhupha, ukushisa, i-voltage, i-SOC (iState of Charge), i-SOH (iState of Health), kunye nemilinganiselo yokukhusela.Iinjongo eziphambili ze-BMS zezi: okokuqala, ukubeka iliso kwimo yebhetri ukuze kubonwe izinto ezingaqhelekanga ngexesha kunye nokuthatha amanyathelo afanelekileyo;okwesibini, ukulawula inkqubo yokutshaja kunye nokukhupha ukuqinisekisa ukuba ibhetri ihlawuliswa kwaye ikhutshwe ngaphakathi kwendawo ekhuselekileyo kunye nokunciphisa umonakalo kunye nokuguga;ngexesha elifanayo, kuyimfuneko ukwenza ukulinganisa kwebhetri, oko kukuthi, ukugcina ukuhambelana kokusebenza kwebhetri ngokulungelelanisa ukuhluka kwentlawulo phakathi komntu ngamnye kwipakethi yebhetri;ukongeza, i-BMS yokugcina amandla nayo ifuna ukuxhotyiswa ngemisebenzi yonxibelelwano ukuvumela imisebenzi efana nokusebenzisana kwedatha kunye nolawulo olukude kunye nezinye iinkqubo.
Imisebenzi emininzi ye-BMS:
1. Ukubeka iliso kunye nokulawula imeko yebhetri: I-BMS yokugcina amandla inokubeka iliso kwiiparamitha zebhetri ezifana ne-voltage, okwangoku, ubushushu, i-SOC kunye ne-SOH, kunye nolunye ulwazi malunga nebhetri.Ikwenza oku ngokusebenzisa abenzi boluvo ukuqokelela idatha yebhetri.
2. Ukulinganisa kwe-SOC (iState of Charge): Ngethuba lokusetyenziswa kweebhetri, kukho ukungalingani kwi-SOC yeebhetri, ezibangela ukuba ukusebenza kwebhetri kuhlaziywe okanye kubangele ukuhluleka kwebhetri.I-Energy Storage BMS inokusombulula le ngxaki ngokusebenzisa iteknoloji yokulinganisa ibhetri, oko kukuthi, ukulawula ukukhutshwa kunye nokuhlawula phakathi kweebhetri ukuze i-SOC yebhetri nganye ihlale ifana.Ukulingana kuxhomekeke ekubeni amandla ebhetri achithwayo okanye adluliselwe phakathi kweebhetri kwaye angohlulwa abe ziindlela ezimbini: ukulinganisa okusebenzayo kunye nokulinganisa okusebenzayo.
3. Ukuthintela ukutshaja kakhulu okanye ukuchithwa okugqithisileyo: Ukutshaja okanye ukukhupha iibhetri ngokugqithisileyo yingxaki enokuthi yenzeke ngepakethi yebhetri, iya kunciphisa umthamo wepakethi yebhetri okanye iyenze ingasebenziseki.Ke, i-BMS yokugcina amandla isetyenziselwa ukulawula amandla ombane ebhetri ngexesha lokutshaja ukuqinisekisa ubume bexesha lokwenyani lebhetri kunye nokuyeka ukutshaja xa ibhetri ifikelele kumthamo wayo omkhulu.
4. Qinisekisa ukubeka iliso elikude kunye nokwesabisa kwenkqubo: I-BMS yokugcina amandla inokudlulisa idatha ngenethiwekhi engenazintambo kunye nezinye iindlela kwaye ithumele idatha yexesha langempela kwi-terminal yokubeka iliso, kwaye ngexesha elifanayo, inokuthumela ukufunyanwa kwephutha kunye nolwazi lwe-alamu ngezikhathi ezithile. ngokoseto lwenkqubo.I-BMS iphinda ixhase izixhobo zokunika ingxelo kunye nokuhlalutya eziguquguqukayo ezinokuvelisa idatha yembali kunye neerekhodi zesiganeko zebhetri kunye nenkqubo yokuxhasa ukubeka iliso kwedatha kunye nokuxilongwa kwempazamo.
5. Ukubonelela ngemisebenzi emininzi yokukhusela: I-BMS yokugcina amandla inokubonelela ngemisebenzi eyahlukeneyo yokukhusela ukukhusela iingxaki ezifana ne-short-circuiting yebhetri kunye ne-over-current, kunye nokuqinisekisa unxibelelwano olukhuselekileyo phakathi kwamacandelo ebhetri.Kwangaxeshanye, inokubona kwaye iphathe iingozi ezinjengokusilela kweyunithi kunye nokusilela kwenqaku elinye.
6. Ukulawula ubushushu bebhetri: Ubushushu bebhetri yenye yezona zinto zibalulekileyo ezichaphazela ukusebenza kwebhetri kunye nobomi.I-BMS yogcino lwamandla inokubeka iliso kwiqondo lobushushu bebhetri kwaye ithathe amanyathelo asebenzayo okulawula ubushushu bebhetri ukuthintela ubushushu ukuba bube phezulu kakhulu okanye bube sezantsi kakhulu ukuba bubangele umonakalo kwibhetri.
Ngokwenene, i-BMS yokugcina amandla isebenza njengengqondo kunye nomgcini wenkqubo yokugcina amandla.Inokubonelela ngokubeka iliso ngokubanzi kunye nokulawulwa kweenkqubo zokugcina ibhetri ukuqinisekisa ukhuseleko lwabo, ukuzinza kunye nokusebenza, ngaloo ndlela ukuqonda iziphumo ezilungileyo kwi-ESS.Ukongezelela, i-BMS inokuphucula ubomi kunye nokuthembeka kwe-ESS, ukunciphisa iindleko zokugcina kunye nobungozi bokusebenza, kunye nokubonelela ngesisombululo sokugcina amandla esiguquguqukayo nesithembekileyo.
