Xa iiNkqubo zoGcino lwaMandla zifuna ukulinganisela okusebenzayo (kwaye xa ukungasebenzi ngokwaneleyo)

Ingxaki yemihla ngemihla yokukhwela ibhayisekile ayilungiselelwanga

Ipakethi ye-elektroniki yebhayisekile yabathengi ijikeleza mhlawumbi kube kanye ngemini, idla ngokuba ngaphantsi. Isixhobo samandla sisetyenziswa ngexesha elifutshane. Uninzi lwezicelo ze-lithium ngokubanzi zinika ipakethi ixesha elaneleyo lokuhlala phantsi, kwaye naluphi na ukungalingani okuncinci phakathi kweeseli kulungiswa kancinci ngasemva. Ukulinganisela okungasebenziyo - ngokuqhelekileyo malunga ne-100mA eshukunyiswa kwiseli ephezulu ngexesha lokufaka itshaja ephezulu - isebenza kakuhle kuloo phrofayili yomsebenzi.

Ugcino lwamandla lwahlukile. Ibhetri yasekhaya edityaniswe nelanga ijikeleza nzulu yonke imihla, unyaka nonyaka. Inkqubo yokugcina yorhwebo inokujikeleza amaxesha amaninzi ngemini. Kwimijikelo emininzi, kwanomahluko omncinci phakathi kweeseli — ukunyamezelana kokuvelisa, umahluko omncinci wobudala, i-gradients yobushushu kwiphakheji ye-16S — iqokelelana ibe yi-voltage drift enokulinganiswa. Iphakheji iyayeka ukuba yintambo efanayo kwaye iqala ukuziphatha njengeseli yayo ebuthathaka. Umthamo wephakheji epheleleyo uyehla, ukungalingani kuyakhula, kwaye ekugqibeleni i-BMS kufuneka iqhawule kwangethuba ukukhusela iseli ebuthathaka — ishiya umthamo osebenzisekayo ubambekile.

Le yindlela yokusilela etsala abathengi bogcino lwamandla ukuba bafikelele ekulinganiseni okusebenzayo. Umbuzo awukokuba ingaba ukusebenza kungcono na ngokubanzi — kukuba ingaba umjikelo womsebenzi weprojekthi yakho ufuna ngokwaneleyo ukuba ukulinganisela okungenziwanga kungakwazi ukuqhubeka.

Oko Kuthethwa yi-100mA Passive Balancing (kwaye apho ingena khona kwi-ESS)

Ukulinganisela okungasebenziyo kusebenza ngokutshisa amandla agqithisileyo avela kwiiseli ezifikelela kwitshaja epheleleyo kuqala, njengobushushu obuncinci kwi-shunt resistor. Umsinga oqhelekileyo we-100mA wokulinganisela ongasebenziyo wanele ukusingatha ukushukuma okuqokeleleka kwizicelo ezilula - kodwa unemida emibini yesakhiwo ebalulekileyo yokugcina:

• Isebenza kuphela xa iphezulu kakhulu.Inkqubo engasebenziyo ifuna iiseli ukuba zifikelele kumda wokulinganisela (ngesiqhelo i-SOC ephezulu) ngaphambi kokuba izilinganise. Kwindawo yokugcina umjikelo ongaphelelanga apho idla ngokufumana itshaja epheleleyo, ukulinganisela okungasebenziyo kufumana amathuba amancinci okusebenza.
• Isantya sayo sincinci xa sithelekiswa nokushukuma okunokuqokelelana imihla ngemihla.Kweminye imijikelo yomsebenzi we-ESS, ukungalingani kunokuqokelelana ngokukhawuleza kunokuba inkqubo yokulinganisela engashukumiyo ye-100mA — esetyenziswa kuphela kwifestile encinci phezulu kwetshaja — inokukwazi ukulungisa, ngoko ke umsantsa unokwanda ngokuhamba kweenyanga endaweni yokuvala.

Kwizicelo ze-shallow-cycle, i-passive balancing ihambelana kakuhle ne-duty cycle kwaye yongeza ixabiso elincinci. Ingxaki ye-ESS ngokukodwa kukungafani phakathi kwe-drift rate kunye ne-correction rate xa i-duty cycle inzima.

Oko Kongezwayo yi-Active Balancing (kwaye Apho ixabiso lokwenyani likhoyo)

Ukulinganisela okusebenzayo kusebenza ngokudlulisela amandla ukusuka kwiiseli ze-voltage ephezulu ukuya kwiiseli ze-voltage ephantsi - ngesiqhelo ngesekethe yokudlulisa i-inductive okanye i-capacitive - endaweni yokuwatshisa njengobushushu. Iziphumo ezimbini ezisebenzayo zilandelayo:

• Umsinga wokulinganisela ophezulu.Apho i-passive imalunga ne-100mA, i-active balancing ezinikeleyo kwindawo yokugcina i-BMS idla ngokuba kuluhlu lwe-1A - ukulungiswa okukhawulezayo kakhulu.
• Ingasebenza ngakumbi kuluhlu lwe-SOC,ayipheleli nje ekutshajisweni okuphezulu. Oku kubalulekile kwindawo yokugcina impahla apho iphakheji isenokungahlali kwi-100% SOC.

Isiphumo esipheleleyo seprojekthi ye-ESS kukuba ukushukuma kombane weseli kunokulungiswa ngesantya esihambelana kakhulu nesantya esiqokelelwayo. Ukulinganisela okusebenzayo kunokunceda ipakethi ihlale ikufutshane nomtya ofanayo ngexesha lobomi bayo benkonzo, kunciphisa amathuba okuba amandla asebenzisekayo abanjwe yiseli ebuthathaka. Isichazi-magama esifanelekileyo ukukhunjulwa: ukusebenza kokulinganisela kwinkonzo kuxhomekeke kwinkqubo yonke — ukuhambelana kwepakethi neeseli ekuqaleni, ukusasazeka kobushushu kumtya, kwaye apho kwifestile ye-SOC ukulinganisela kuvunyelwe ukusebenza khona. Idatha ethile yokulinganisela yoqwalaselo lwepakethi ethile yinto ekufuneka iqinisekiswe neqela lobunjineli kunokuba kuthathwe kwiphepha ledatha kuphela.

Xa i-Passive Balancing Yanele (Musa ukuCacisa kakhulu)

Ukulinganisela okusebenzayo akusiyonto yokuhlaziya ezenzekelayo. Kwiintlobo ngeentlobo zezicelo, i-passive yimpendulo echanekileyo ngokwenene:

• Iinkqubo zokulondoloza ezilula ezijikeleza rhoqo
• Iipakethi ze-Telecom UPS ezisebenza ngokuyintloko njengezokulinda kwaye ezingaqhelekanga zijikeleze ngobunzulu
• Indawo yokugcina izinto ezincinci zabathengi apho uqoqosho lweprojekthi lungangqinelani neendleko ezongezelelweyo ze-BMS
• Iiseli ezihambelana kakuhle ezinokunyamezelana okuqinileyo kokuqala, apho ukutyibilika kuqokelelwa khona kancinci

Ukucacisa i-active balancing kwezi zicelo kongeza iindleko ngaphandle kwenzuzo elinganayo. Umthengisi olungileyo uya kukuxelela xa impendulo echanekileyo yeprojekthi yakho ingasebenzi - kwaye uphawu olubalulekileyo olufanele ukuqwalaselwa ngumthengisi ocebisa i-active balancing kuyo yonke iprojekthi ngaphandle kwesizathu esicacileyo sobugcisa esinxulumene nomjikelo wakho womsebenzi.

Xa i-Active Balancing ifanelekile ukucaciswa kwiProjekthi yakho yokugcina izinto
