Iinkqubo yebhetringundoqo wenkqubo yokugcina amandla, equlathe amakhulu eeseli ezisilinda okanyeiiseli ze-prismaticngolandelelwano nangokuhambelana. Ukungangqinelani kweebhetri zokugcina amandla kubhekisa kakhulu ekungahambelani kweeparameter ezifana nomthamo webhetri, ukumelana kwangaphakathi, kunye nobushushu. Xa iibhetri ezingangqinelaniyo zisetyenziswa ngolandelelwano nangokuhambelana, kuya kubakho iingxaki ezilandelayo:

1. Ukulahleka komthamo okhoyo

Kwinkqubo yokugcina amandla, iiseli ezizimeleyo zidibene ngokwee-series kunye ne-parallel ukwenza ibhokisi yebhetri, iibhokisi zebhetri zidibene ngokwee-series kunye ne-parallel ukwenza iqela lebhetri, kwaye ii-betri clusters ezininzi zidibene ngokuthe ngqo kwi-DC busbar efanayo ngokwee-series. Izizathu zokungahambelani kwebhetri okukhokelela ekulahlekelweni kwamandla asebenzisekayo ziquka ukungahambelani kwee-series kunye nokungahambelani ngokwee-series.

•Ukulahleka kokungalingani kochungechunge lwebhetri
Ngokomgaqo webhareli, amandla ochungechunge lwenkqubo yebhetri axhomekeke kwibhetri enye enomthamo omncinci. Ngenxa yokungangqinelani kwebhetri enye ngokwayo, umahluko wobushushu kunye nokunye ukungangqinelani, amandla asebenzisekayo ebhetri nganye nganye aya kwahluka. Ibhetri enye enomthamo omncinci iyatshajwa ngokupheleleyo xa itshajwa kwaye ikhutshwe xa ikhutshwa, nto leyo ethintela ukutshajwa kwezinye iibhetri enye kwinkqubo yebhetri. Amandla okukhupha, okubangela ukwehla kwamandla akhoyo kwinkqubo yebhetri. Ngaphandle kolawulo olusebenzayo olulinganiselayo, ngokwanda kwexesha lokusebenza, ukuncitshiswa kunye nokwahlulwa kwamandla ebhetri enye kuya kwandiswa, kwaye amandla akhoyo enkqubo yebhetri aya kukhawulezisa ngakumbi ukwehla.

•Ukulahleka kokungahambelani kweqela lebhetri ngaxeshanye

Xa amaqela eebhetri eqhagamshelwe ngokuthe ngqo ngaxeshanye, kuya kubakho umjikelo wamandla ojikelezayo emva kokutshaja nokukhupha, kwaye iivoltage zeqela ngalinye leebhetri ziya kunyanzeleka ukuba zilingane. Ukungoneliseki kunye nokukhupha okungapheliyo kuya kubangela ukulahleka komthamo webhetri kunye nokunyuka kobushushu, kukhawulezise ukubola kwebhetri, kwaye kunciphise umthamo okhoyo wenkqubo yebhetri.

Ukongeza, ngenxa yokumelana okuncinci kwangaphakathi kwebhetri, nokuba umahluko wevolthi phakathi kwamaqela okubangelwa kukungangqinelani yivolts ezimbalwa kuphela, umbane ongalinganiyo phakathi kwamaqela uya kuba mkhulu. Njengoko kubonisiwe kwidatha elinganisiweyo yesikhululo samandla kwitheyibhile engasezantsi, umahluko kumbane wokutshaja ufikelela kwi-75A (Xa kuthelekiswa nomndilili wethiyori, ukuphambuka yi-42%), kwaye umbane wokuphambuka uya kukhokelela ekutshajisweni kakhulu nasekuchithekeni kakhulu kwamanye amaqela ebhetri; kuya kuchaphazela kakhulu ukusebenza kakuhle kokutshaja nokukhupha, ubomi bebhetri, kwaye kukhokelela nakwiingozi ezinkulu zokhuseleko.

2. Ukwahluka okukhawulezileyo kunye nobomi obufutshane beeseli ezizimeleyo obubangelwa kubushushu obungaguqukiyo

Ubushushu yeyona nto ibalulekileyo echaphazela ubomi benkqubo yokugcina amandla. Xa ubushushu bangaphakathi benkqubo yokugcina amandla bunyuka nge-15°C, ubomi benkqubo buya kuncitshiswa ngaphezulu kwesiqingatha. Ibhetri ye-lithium iya kuvelisa ubushushu obuninzi ngexesha lenkqubo yokutshaja nokukhupha, kwaye umahluko wobushushu bebhetri enye uya kwandisa ukungangqinelani kokumelana kwangaphakathi kunye nomthamo, okuya kukhokelela ekuphuhlisweni ngokukhawuleza kwebhetri enye, kunciphise ubomi bomjikelo wenkqubo yebhetri, kwaye kubangele neengozi zokhuseleko.

Ungajongana njani nokungangqinelani kweebhetri zokugcina amandla?

Ukungahambelani kweebhetri yimbangela yeengxaki ezininzi kwiinkqubo zokugcina amandla ezikhoyo. Nangona ukungahambelani kweebhetri kunzima ukukuphelisa ngenxa yeempawu zeekhemikhali zeebhetri kunye nempembelelo yendawo esetyenziswayo, iteknoloji yedijithali, iteknoloji ye-elektroniki yamandla kunye neteknoloji yokugcina amandla inokudityaniswa ukuze kusetyenziswe umbane. Ukulawulwa kweteknoloji ye-elektroniki kunciphisa impembelelo yokungahambelani kweebhetri ze-lithium, nto leyo enokunyusa kakhulu amandla asebenzisekayo eenkqubo zokugcina amandla kwaye iphucule ukhuseleko lwenkqubo.

•Iteknoloji yokulinganisela esebenzayo ijonga i-voltage kunye nobushushu bebhetri nganye ngexesha langempela, isusa kakhulu ukungangqinelani konxibelelwano lwebhetri, kwaye yonyusa amandla akhoyo enkqubo yokugcina amandla ngaphezulu kwe-20% kumjikelo wobomi bonke.

•Kuyilo lombane lwenkqubo yokugcina amandla, ulawulo lokutshaja kunye nokukhupha ibhetri nganye lwenziwa ngokwahlukeneyo, kwaye iibhetri aziqhagamshelwanga ngaxeshanye, nto leyo ethintela ingxaki yokujikeleza kwegazi ebangelwa luqhagamshelo oluhambelanayo lweDC, kwaye iphucula ngokufanelekileyo amandla akhoyo enkqubo.

•Ulawulo lobushushu oluchanekileyo ukuze kwandiswe ubomi benkqubo yokugcina amandla

Ubushushu beseli nganye nganye buyaqokelelwa kwaye bujongwe ngexesha langempela. Ngokusebenzisa ukulinganisa ubushushu beCFD yamanqanaba amathathu kunye nenani elikhulu ledatha yovavanyo, uyilo lobushushu benkqubo yebhetri luyaphuculwa, ukuze umahluko omkhulu wobushushu phakathi kweeseli enye zenkqubo yebhetri ube ngaphantsi kwe-5 °C, kwaye ingxaki yokwahluka kweseli enye okubangelwa kukungahambelani kobushushu isonjululwe.

Ufuna ukuvelisa ibhetri ye-lithium eyenzelwe wena ngokweemfuno ezikhethekileyo, wamkelekile ukubonisana neqela le-LIAO ukuze ufumane iinkcukacha ezithe vetshe.
