Impendulo Esheshayo

Uma amabhethri amaningana e-LiFePO4 esebenza ngesikhathi esifanayo, amandla kagesi aboniswayo ephakethe ngalinye angase angafani ngaso sonke isikhathi.

Uma amaphakethe amane enikeza i-120A iyonke,120A ÷ 4 = 30A ngephakethe ngalinye. I-30A iwusizo njenge-isilinganiso sokubhekisela, kodwa akusho ukuthi wonke amaphakethe kumele ahlale elinganisa u-30A ngqo.

Esikhundleni sokwahlulela ukufundwa okukodwa, hlola ukuthi ngabeiphakethe elifanayo lithwala ugesi omningi noma omncane ngokuphindaphindiwe ngaphansi kwezimo zokusebenza ezifanayo.

Indlela yokuxilonga:I-Current → Voltage → SOC → Isimo se-BMS → Indlela Yokuxhumana

Umgomo uwukunquma ukuthi ubona yini ukushintshashintsha kokusebenza kwesikhashana noma umehluko ophindaphindwayo wezinga lephakethe odinga uphenyo olwengeziwe.

1. Okokuqala, Qhathanisa Amaphakethe Ngaphansi Kwesimo Esifanayo

Ungaxilongi ugesi wephakethe ongalingani kusuka kusithombe-skrini esisodwa. Qhathanisa amaphakethe ngesikhathi esifanayo, ngaphansi kwesimo esifanayo sokushaja noma sokukhipha, nomthwalo wesistimu ofanayo, futhi usebenzisa indlela efanayo yokuqapha. Bese uphinda lokho okubonwayo.

Umbuzo obalulekile: Ingabe iphakethe elifanayo libonisa ngokuphindaphindiwe ugesi ohlukile kwamanye?

Umehluko wesikhathi esisodwa unikeza ulwazi oluncane kakhulu kunephethini ephindaphindwayo.

2. Ungaphathi Inani Eliphelele Lamanje ÷ Inani Lephakethe Njengomkhawulo Wokudlula/Ukwehluleka

Ake sithi amaphakethe amane ahambisanayo ahlinzeka nge-120A. Isilinganiso sokubhekisela siyi-120A ÷ 4 = 30A ngephakethe ngalinye.

Lokhu kukusiza ukuthi uqhathanise amaphakethe amane, kodwa akusho ukuthi wonke amaphakethe kumele ahlale ekhombisa u-30A ngqo, noma ukuthi iphakethe elingaphezu noma elingaphansi kuka-30A linephutha ngokuzenzakalelayo.

Akukho mehluko wephesenti ojwayelekile okufanele uphathwe ngokuzenzakalelayo njengowamukelekayo noma ongamukeleki kuzo zonke izinhlelo zebhethri ezihambisanayo.

Isamba Samanje ÷ Inani Lamaphakethe = Isilinganiso Sereferensi, akuyona umkhawulo wokwamukelwa ojwayelekile.

3. Uma Umehluko Uphinda, Qhathanisa Okungaphezu Kwamanje

Uma iphakethe elifanayo lihlala liphethe ugesi omningi noma omncane, ungayixilongi inkinga ngogesi wodwa.

Isheke	Lokho Okufunayo
Okwamanje	Ingabe iphakethe elifanayo liphindelela liyinto engavamile?
I-voltage	Ingabe lelo phakethe libonisa nephethini ehlukile ye-voltage?
I-SOC	Ingabe i-SOC yayo nayo iziphatha ngendlela ehlukile kunokubuka okuphindaphindiwe?
Isimo se-BMS	Ingabe isesimweni esihlukile sokushaja, sokukhishwa noma sokuvikelwa?

I-SOC iwusizo lapha njengesignali esekelayo. Ukufundwa okuhlukile kwe-SOC akubonisi ukuthi kungani ugesi uhlukile.

4. Bese uhlola iphakethe kanye nendlela yalo yokuxhumana

Uma idatha yephakheji nayo ihlukile

Qhathanisa i-voltage yephakethe elithintekile, i-SOC, izinga lokushisa lapho litholakala khona, isimo sokusebenza kwe-BMS, kanye nokuziphatha kwamanje okuphindaphindiwe. Inhloso ukuthola ukuthi umehluko wamanje uyingxenye yephethini ebanzi yezinga lephakethe.

Ugesi ohlukile uwukubonwa, hhayi okwamanje ukuxilongwa.

Uma idatha yephakethe ifana kodwa amandla ayo ahlala ehlukile

Hlola indlela ephelele yokuxhumana ehambisanayo. Qhathanisa izintambo, izixhumi, amatheminali, ukuxhumana kwebha yebhasi, kanye nesimo sokuxhumana.

Umbuzo owusizo:Ingabe leli phakethe linendlela kagesi efanayo eya endaweni yokuxhuma evamile?

5. Nquma: Ukuqapha noma Uphenye?

Lokho Okubonayo	Okufanele ngikwenze
Idatha yamanje iyahluka okwesikhashana, kuyilapho eminye idatha yephakethe ihlala ifana ngokufanele	Imonithangaphansi kwezimo ezifanayo
Iphakethe elifanayo liphindelela liphethe ugesi omningi noma omncane	Qhathanisaisimo se-voltage, i-SOC kanye ne-BMS
I-outlier yamanje iphinde ibonise umehluko ophindaphindwayo we-voltage, i-SOC noma isimo	Phenya iphakethe elithintekile
Idatha yephakeji ibukeka ifana kodwa igatsha elilodwa lihlala liyigatsha elingaphandle kwamanje	Hlola indlela yokuxhumana ehambisanayo
Iphakethe elilodwa lingena ngokuphindaphindiwe esimweni sokushaja/sokukhipha noma sokuvikela esihlukile	Hlola isimo sokusebenza kwephakethe/i-BMS
Idatha etholakalayo ayikakwazi ukuchaza iphethini	Cela ukuqinisekiswa kwephrojekthi ethile

6. Indlela Ukuqapha Amaphakethe Amaningi Kwe-DALY Okuwusizo Ngayo

OkusekelwayoI-DALY yesizukulwane sesi-4 se-Home Energy Storage BMSukucushwa kwamaphakethe amaningi, ulwazi lwephakethe ngalinye lungabukwa ukuze kuqhathaniswe, kufaka phakathi Inombolo Yephakethe, Isimo, I-Voltage, I-Current, i-SOC, i-CHG-MOS kanye ne-DSG-MOS. Ukucushwa okusekelwayo kungafaka kufika kuAmaphakethe ebhethri angu-16.

Ungaqhathanisa amaphakethe ngamanye bese ubona ukuthi yiliphi iphakethe eliziphatha ngendlela ehlukile ngokuphindaphindiwe.

Leli khono lokuqapha akufanele lihunyushwe njengesiqinisekiso sokuthi wonke amaphakethe afanayo azohlala ephethe ugesi ofanayo.

7. Yini Okufanele Uyithumele ku-DALY ukuze Iqinisekiswe?

Uma iphakethe elifanayo libonisa ngokuphindaphindiwe ugesi ohlukile futhi idatha etholakalayo ingachazi ukuthi kungani, lungiselela: i-chemistry yebhethri kanye nenani lika-S, i-Ah ngephakethe ngalinye, inani lamaphakethe, imodeli ye-BMS eqondile, idatha yamanje/i-voltage/i-SOC/yesimo esivumelanisiwe, ukuhlelwa kwekhebula kanye ne-busbar, uhlobo/imodeli ye-inverter, isimo sokusebenza, nokuthi ngabe iphakethe elifanayo liba yinto engavamile ngokuphindaphindiwe.

Imibuzo Evame Ukubuzwa

Ingabe amabhethri e-LiFePO4 ahambisanayo kufanele ahlale ebonisa ugesi ofanayo?

Cha. Ingqikithi yamanje ehlukaniswe ngenani lamaphakethe iwusizo njengesilinganiso sokubhekisela, hhayi njengemfuneko yokudlula/ukwehluleka jikelele. Hlola ukuthi iphakethe elifanayo liziphatha ngendlela ehlukile ngokuphindaphindiwe ngaphansi kwezimo zokusebenza ezifanayo.

Ingabe izintambo kanye nokuxhumeka kungathinta ukwabelana kwamanje phakathi kwamaphakethe afanayo?

Zingathonya ukusatshalaliswa kwamanje. Uma igatsha elilodwa libonisa ngokuphindaphindiwe ugesi ohlukile, qhathanisa izintambo zalo, izixhumi, amatheminali kanye nokuxhumeka kwebha yebhasi namanye amagatsha.

Ingabe i-pack current ehlukile isho ukuthi i-BMS inephutha?

Akunjalo ngempela. Ugesi ohlukile uwukuqaphela, hhayi ukuxilongwa. Qhathanisa ukuziphatha kogesi okuphindaphindiwe ne-pack voltage, i-SOC, isimo se-BMS kanye nendlela yokuxhumanisa ehambisanayo ngaphambi kokuthola imbangela.
