Imininingwane yebhethri ye-lithium efakwe kwirack

Emkhakheni okhulayo wezixazululo zokugcina amandla,amabhethri e-lithium abekekayosebeyisinqumo esidumile sezinhlelo zokusebenza zezentengiselwano nezimboni. Lawa masistimu aklanyelwe ukuhlinzeka ngesitoreji samandla esithembekile, esisebenza kahle futhi esingalawuleki, okuwenza alungele ukusetshenziswa okuhlukahlukene kusukela ezikhungweni zedatha kuya ekuhlanganisweni kwamandla avuselelekayo. Lesi sihloko sibheka kabanzi ukucaciswa kwamabhethri e-lithium afakwe kwi-rack, egqamisa izici zawo, izinzuzo, kanye nezinhlelo zokusebenza.

1. Amandla

Amandla amabhethri e-lithium afakwe kwi-rack ngokuvamile akalwa ngamahora angama-kilowatt (kWh). Lokhu kucaciswa kukhombisa ukuthi mangakanani amandla ibhethri elingawagcina futhi lilethe. Amandla ajwayelekile asukela ku-5 kWh kuye kwangaphezu kuka-100 kWh, kuye ngokuthi isetshenziswa kanjani. Isibonelo, isikhungo sedatha singase sidinge umthamo omkhulu ukuze kuqinisekiswe ukunikezwa kwamandla okungaphazamiseki, kuyilapho uhlelo lokusebenza oluncane lungase ludinge amahora ama-kilowatt ambalwa kuphela.

2. Amandla kagesi

Amabhethri e-lithium afakwe kwi-rack ngokuvamile asebenza kuma-voltage ajwayelekile afana no-48V, 120V noma 400V. Ukucaciswa kwe-voltage kubalulekile ngoba kunquma ukuthi ibhethri lihlanganiswe kanjani nesistimu kagesi ekhona. Amasistimu kagesi aphezulu angasebenza kahle kakhulu, adinge amandla amancane okukhipha amandla afanayo, ngaleyo ndlela ehlise ukulahleka kwamandla.

3. Impilo yomjikelezo

Impilo yomjikelezo isho inombolo yokushaja nemijikelezo yokukhipha ibhethri elingadlula kuyo ngaphambi kokuba umthamo walo wehle kakhulu. Amabhethri e-lithium afakwe kwi-Rack avamise ukuba nempilo yomjikelezo wemijikelezo engu-2,000 kuya ku-5,000, kuye ngokujula kokukhipha (DoD) nezimo zokusebenza. Impilo yomjikelezo omude isho izindleko eziphansi zokushintsha nokusebenza okungcono kwesikhathi eside.

4. Ukujula Kokukhipha (DoD)

Ukujula kokukhipha amanzi kuyinkomba ebalulekile yokuthi ungakanani umthamo webhethri ongasetshenziswa ngaphandle kokulimaza ibhethri. Amabhethri e-lithium afakwe kwi-rack ngokuvamile ane-DoD engu-80% kuya ku-90%, evumela abasebenzisi ukuthi basebenzise amandla amaningi agciniwe. Lokhu kuzuzisa kakhulu ezinhlelweni ezidinga ukuhamba ngamabhayisikili njalo, njengoba kukhulisa ukusetshenziswa kwamandla atholakalayo ebhethri.

5. Ukusebenza kahle

Ukusebenza kahle kwesistimu yebhethri ye-lithium efakwe kwi-rack kuyisilinganiso sokuthi angakanani amandla agcinwa ngesikhathi sokushaja nokukhipha imijikelezo. Amabhethri e-lithium ekhwalithi ephezulu avamise ukuba nokusebenza kahle kokuya nokubuya okungu-90% kuya ku-95%. Lokhu kusho ukuthi ingxenye encane kuphela yamandla elahlekile ngesikhathi sokushaja nokukhipha, okwenza kube isisombululo sokugcina amandla esingabizi kakhulu.

6. Izinga Lokushisa

Izinga lokushisa elisebenzayo kungenye imininingwane ebalulekile yamabhethri e-lithium afakwe kwi-rack. Amabhethri amaningi e-lithium aklanyelwe ukusebenza kahle phakathi kwezinga lokushisa elingu -20°C kuya ku-60°C (-4°F kuya ku-140°F). Ukugcina ibhethri ngaphakathi kwalolu banga lokushisa kubalulekile ekusebenzeni kahle nokuphila isikhathi eside. Amanye amasistimu athuthukile angase ahlanganise izici zokulawula ukushisa ukuze kulawule izinga lokushisa nokuthuthukisa ukuphepha.

7. Isisindo nobukhulu

Isisindo nosayizi wamabhethri e-lithium afakwe kwi-rack kuwukucatshangelwa okubalulekile, ikakhulukazi uma efaka endaweni elinganiselwe. Lawa mabhethri avamise ukubalula futhi aminyene kakhulu kunamabhethri endabuko e-lead-acid, awenza kube lula ukuwaphatha nokuwafaka. Iyunithi yebhethri ye-lithium evamile efakwe kwi-rack ingaba nesisindo esiphakathi kwamakhilogremu angu-50 no-200 (amaphawundi angu-110 no-440), kuye ngomthamo wayo kanye nomklamo.

8. Izici Zokuphepha

Ukuphepha kubalulekile ezinhlelweni zokugcina amandla. Amabhethri e-lithium afakwe kwi-Rack anemisebenzi eminingi yokuphepha efana nokuvikela ukuphuma kwe-thermal, ukuvikela ukushajwa ngokweqile, nokuvikela isekethe emfushane. Amasistimu amaningi futhi afaka isistimu yokuphatha ibhethri (i-BMS) yokuqapha impilo yebhethri ukuze kuqinisekiswe ukusebenza okuphephile nokwelula impilo yayo yesevisi.

Ukusetshenziswa kwebhethri ye-lithium efakwe kwi-rack

Amabhethri e-lithium afakwa nge-Rack ahlukahlukene futhi angasetshenziswa ezinhlelweni ezahlukahlukene, kufaka phakathi:

- Isikhungo Sedatha: Sinikeza amandla okulondoloza futhi siqinisekisa isikhathi lapho ugesi ucisha.

- I-Renewable Energy Systems: Gcina amandla akhiqizwe amaphaneli elanga noma izinjini zomoya ukuze zisetshenziswe kamuva.

- Ezokuxhumana: Ukunikeza amandla athembekile kumanethiwekhi okuxhumana.

- Izimoto zikagesi: Izixazululo zokugcina amandla njengeziteshi zokushaja.

- Izicelo Zezimboni: Sekela imisebenzi yokukhiqiza kanye nempahla.

Ekuphetheni

Amabhethri e-lithium afakwe kwi-rackzimelela intuthuko enkulu kubuchwepheshe bokugcina amandla. Ngokucaciswa kwazo okuhlaba umxhwele, okuhlanganisa umthamo omkhulu, impilo yomjikelezo omude nokusebenza kahle okuvelele, zifaneleka kahle ezinhlotsheni eziningi zezinhlelo zokusebenza. Njengoba isidingo sezixazululo zamandla ezinokwethenjelwa nezisimeme sikhula, amabhethri e-lithium afakwe ngamarakhi azodlala indima ebalulekile ekulolongeni ikusasa lokugcina amandla. Noma ngabe ezentengiso, ezezimboni noma izicelo zamandla avuselelekayo, lezi zinhlelo zihlinzeka ngezixazululo eziqinile nezingalawuleki ukuze kuhlangatshezwane nezidingo zamandla zanamuhla nezesikhathi esizayo.
