Lapho Izinhlelo Zokugcina Amandla Zidinga Ukulinganisela Okusebenzayo (futhi Lapho Ukungenzi Kalula Kwanele)

Inkinga Yokuhamba Ngebhayisikili Yansuku Zonke Ukulinganisela Okungenamsebenzi Akuzange Kwenzelwe

Iphakethe lebhayisikili labathengi lijikeleza mhlawumbe kanye ngosuku, ngokuvamile lingaphansi. Ithuluzi lamandla lisetshenziswa ngezikhathi ezimfushane. Izinhlelo eziningi ze-lithium ezijwayelekile zinikeza iphakethe isikhathi esanele sokuhlala uphumule, futhi noma yikuphi ukungalingani okuncane phakathi kwamaseli kulungiswa kancane ngemuva. Ukulinganisela okungasebenzi - ngokuvamile cishe i-100mA eshuthwa kuseli eliphezulu kakhulu ngesikhathi sokushaja okuphezulu - kusebenza kahle kakhulu kuleyo phrofayili yomsebenzi.

Isitoreji samandla sihlukile. Ibhethri lasekhaya elihlanganiswe yilanga lijikeleza ngokujulile nsuku zonke, unyaka nonyaka. Uhlelo lokugcina lwezentengiselwano lungajikeleza izikhathi eziningi ngosuku. Ezinkulungwaneni zemijikelezo, ngisho nomehluko omncane phakathi kwamaseli - ukubekezelelana kokukhiqiza, umehluko omncane wobudala, amazinga okushisa ephaketheni le-16S - aqoqana abe yi-voltage drift elinganisekayo. Iphakethe liyayeka ukuba yintambo efanayo futhi liqala ukuziphatha njengeseli lalo elibuthakathaka kakhulu. Umthamo wephakethe lonke uyehla, ukungalingani kuyakhula, futhi ekugcineni i-BMS kufanele inqamule kusenesikhathi ukuze ivikele iseli elibuthakathaka kakhulu - ishiye umthamo osebenzisekayo ubambekile.

Lena yindlela yokwehluleka edonsela abathengi besitoreji samandla ekulinganiseni okusebenzayo. Umbuzo awukhona ukuthi ukusebenza kungcono yini ngokuvamile — kodwa ukuthi umjikelezo womsebenzi wephrojekthi yakho udinga ngokwanele ukuthi ukulinganisela okusebenzayo kungakwazi ukuqhubeka.

Lokho Okwenziwa Yi-100mA Passive Balancing Ngempela (nokuthi Ingaphumeleli Kanjani Ku-ESS)

Ukulinganisela okungasebenzi kahle kusebenza ngokushisa amandla amaningi avela kumaseli afinyelela ukushaja okugcwele kuqala, njengokushisa okuncane ku-resistor ye-shunt. Umshini wokulinganisela ongasebenzi ojwayelekile we-100mA wanele ukusingatha ukukhukhuleka okuqongelela ezinhlotsheni ezilula - kodwa unemikhawulo emibili yesakhiwo ebalulekile yokugcina:

• Isebenza kuphela phezulu kakhulu.Uhlelo olungasebenzi ludinga amaseli ukuthi afinyelele umkhawulo wokulinganisela (ngokuvamile i-SOC ephezulu) ngaphambi kokuba lukwazi ukuwalinganisa. Ekusebenzeni kokugcina umjikelezo ongaphelele okungavamile ukubona ukushaja okugcwele, ukulinganisela okungasebenzi kuthola amathuba amancane okusebenza.
• Izinga layo lincane uma liqhathaniswa nokukhukhuleka okungase kuqongeleleke nsuku zonke.Kweminye imijikelezo yomsebenzi we-ESS, ukungalingani kunganqwabelana ngokushesha kunokuba uhlelo lokulinganisela olungasebenzi lwe-100mA — olusetshenziswa kuphela efasiteleni elilinganiselwe phezulu kweshaja — lukwazi ukulungisa, ngakho-ke igebe linganda izinyanga eziningi kunokuba livaleke.

Ngezinhlelo zokusebenza zomjikelezo ongajulile, ukulinganisela okungasebenzi kahle kuhambisana kahle nomjikelezo womsebenzi futhi kwengeza izindleko ezincane kakhulu. Inkinga ye-ESS ikakhulukazi ukungafani phakathi kwesilinganiso sokukhukhuleka kanye nesilinganiso sokulungisa lapho umjikelezo womsebenzi unzima.

Lokho Okwengezwayo Ukulinganisela Okusebenzayo (nokuthi Kukuphi Inani Langempela)

Ukulinganisela okusebenzayo kusebenza ngokudlulisa amandla kusuka kumaseli ane-voltage ephezulu kuya kumaseli ane-voltage ephansi — ngokuvamile ngesekethe yokudlulisa engenisayo noma ekwazi ukudlulisa — kunokuyishisa njengokushisa. Imiphumela emibili esebenzayo ilandela:

• Umthamo wokulinganisela ophezulu.Lapho i-passive icishe ibe yi-100mA, i-active balancing ezinikele kwisitoreji i-BMS ivame ukuba sebangeni le-1A — ukulungiswa okusheshayo okukhulu.
• Ingasebenza kakhulu kububanzi be-SOC,hhayi nje kuphela lapho kushajwa khona kakhulu. Lokhu kubalulekile ekusebenzeni kwesitoreji lapho iphakethe lingase lingabi ngaphansi kwe-100% SOC.

Umphumela ophelele wephrojekthi ye-ESS ukuthi ukukhukhuleka kwamandla eseli kungalungiswa ngesivinini esifanelana kakhulu nesivinini esiqongelela ngaso. Ukulinganisela okusebenzayo kungasiza iphakethe ukuthi lihlale liseduze nentambo efanayo phakathi nesikhathi salo sokusebenza, kunciphisa amathuba okuthi amandla asebenzisekayo abanjwe yiseli elibuthakathaka kakhulu. Isihlungi okufanele sikhunjulwe: ukulinganisela ukusebenza kwesevisi kuncike ohlelweni lonke — ukufaniswa kwephakeji neseli ekuqaleni, ukusabalala kokushisa kuyo yonke intambo, nokuthi efasiteleni le-SOC ukulinganisela kuvunyelwe ukusebenza kuphi. Idatha yokulinganisela ethile yokucushwa kwephakeji ethile yinto okufanele iqinisekiswe nethimba lobunjiniyela kunokucabanga kusukela eshidini ledatha kuphela.

Uma Ukulinganisela Okungashintshi Kwanele (Ungacacisi Kakhulu)

Ukulinganisela okusebenzayo akuyona intuthuko ezenzakalelayo. Kuzinhlelo zokusebenza eziningi ezahlukene, i-passive iyimpendulo efanele ngempela:
