Iingxaki zokungahambelani kunye nezisombululo zeebhetri zokuGcina amandla

Iinkqubo yebhetringundoqo wenkqubo yonke yokugcina amandla, equka amakhulu eeseli ze-cylindrical okanyeiiseli zeprismatickuthotho kunye nokuhambelana.Ukungahambelani kweebhetri zokugcina amandla ikakhulu kubhekiselele ekungahambelani kweeparamitha ezifana nomthamo webhetri, ukumelana kwangaphakathi, kunye nobushushu.Xa iibhetri ezingahambelaniyo zisetyenziswa kuthotho kunye nokuhambelana, kuya kwenzeka ezi ngxaki zilandelayo:

1. Ukulahleka kwamandla akhoyo

Kwinkqubo yokugcina amandla, iiseli ezilodwa zidityaniswe kuluhlu kunye nokuhambelana ukwenza ibhokisi yebhetri, iibhokisi zebhetri zixhunyiwe kuchungechunge kunye nokuhambelana ukwenza iqoqo lebhetri, kunye namaqela amaninzi ebhetri axhunyiwe ngokuthe ngqo kwi-busbar ye-DC efanayo ngokufana. .Iimbangela zokungahambelani kwebhetri okukhokelela ekulahlekelweni kwamandla asebenzisekayo kubandakanya ukungahambelani kochungechunge kunye nokungahambelani okufanayo.

•Ilahleko yokungangqinelani kothotho lwebhetri
Ngokomgaqo we-barrel, umthamo woluhlu lwenkqubo yebhetri ixhomekeke kwibhetri enye enomthamo omncinci.Ngenxa yokungahambelani kwebhetri enye ngokwayo, ukuhluka kweqondo lokushisa kunye nokunye okungahambelaniyo, umthamo osebenzisekayo webhetri enye iya kwahluka.Ibhetri enye enomthamo omncinci itshajwa ngokupheleleyo xa itshaja kwaye ikhutshwe xa ikhupha, nto leyo ethintela ukutshajiswa kwezinye iibhetri enye kwisixokelelwano sebhetri.Umthamo wokukhupha, okukhokelela ekunciphiseni umthamo okhoyo wenkqubo yebhetri.Ngaphandle kokulawula okusebenzayo okulinganayo, kunye nokwanda kwexesha lokusebenza, ukucutha kunye nokwahlula umthamo webhetri enye kuya kwandiswa, kwaye umthamo okhoyo wenkqubo yebhetri uya kukhawulezisa ukuhla.

•Ilahleko yebhetri edityanisiweyo yokungangqinelani

Xa amaqoqo ebhetri exhunywe ngokuthe ngqo kwi-parallel, kuya kubakho into ejikelezayo yangoku emva kokutshaja kunye nokukhutshwa, kwaye i-voltages yeqela ngalinye lebhetri iya kunyanzeliswa ukuba ilinganise.Ukunganeliseki kunye nokukhutshwa okungapheliyo kuya kubangela ukulahlekelwa kwamandla ebhetri kunye nokunyuka kweqondo lokushisa, ukukhawulezisa ukubola kwebhetri, kunye nokunciphisa umthamo okhoyo wenkqubo yebhetri.

Ukongezelela, ngenxa yokuchasana okuncinci kwangaphakathi kwebhetri, nokuba umehluko we-voltage phakathi kwamaqela abangelwa ukungahambelani ngama-volts ambalwa kuphela, ukungalingani kwangoku phakathi kwamaqela kuya kuba mkhulu.Njengoko kubonisiwe kwidatha elinganisiweyo yesikhululo samandla kwitheyibhile engezantsi, umahluko kwi-chargeing current ifikelela kwi-75A (Xa kuthelekiswa ne-avareji yethiyori, ukutenxa yi-42%), kwaye ukuphambuka kwangoku kuya kukhokelela ekuhlawuleni ngokugqithiseleyo kunye nokukhutshwa ngokugqithisileyo kwamanye amaqoqo ebhetri. ;iyakuchaphazela kakhulu ukutshaja nokukhupha ukusebenza kakuhle, ubomi bebhetri, kwaye ide ikhokelele kwiingozi ezimandundu zokhuseleko.

2.Ukwahlula okukhawulezileyo kunye nobomi obufutshane beeseli ezibodwa ezibangelwa ukushisa okungahambelaniyo

Ubushushu yeyona nto ibalulekileyo echaphazela ubomi benkqubo yokugcina amandla.Xa ukushisa kwangaphakathi kwenkqubo yokugcina amandla kunyuka nge-15 ° C, ubomi benkqubo buya kufinyezwa ngaphezu kwesiqingatha.Ibhetri ye-lithium iya kuvelisa ubushushu obuninzi ngexesha lokutshaja kunye nenkqubo yokukhupha, kwaye ukuhluka kweqondo lokushisa kwebhetri enye kuya kwandisa ukungahambisani nokuchasana kwangaphakathi kunye nomthamo, okuya kukhokelela ekuhlukaniseni ngokukhawuleza kwebhetri enye, ukunciphisa umjikelo. ubomi benkqubo yebhetri, kwaye ibangele iingozi zokhuseleko.

Indlela yokujongana nokungahambelani kweebhetri zokugcina amandla?

Ukungahambelani kwebhetri yingcambu yeengxaki ezininzi kwiinkqubo zangoku zokugcina amandla.Nangona ukungahambelani kwebhetri kunzima ukuphelisa ngenxa yeempawu zeekhemikhali zeebhetri kunye nempembelelo yendawo yesicelo, iteknoloji yedijithali, iteknoloji ye-electronics yamandla kunye nokugcinwa kweteknoloji yokugcina amandla ingadibaniswa ukusebenzisa umbane.Ukulawulwa kobuchwephesha be-elektroniki kunciphisa impembelelo yokungahambelani kwebhetri ye-lithium, enokunyusa kakhulu amandla okusetyenziswa kweenkqubo zokugcina amandla kunye nokuphucula ukhuseleko lwenkqubo.

• Itekhnoloji yokulinganisa esebenzayo ibeka iliso kwi-voltage kunye nobushushu bebhetri nganye ngexesha lokwenyani, isusa kakhulu ukungahambelani koqhagamshelo loluhlu lwebhetri, kwaye yandisa umthamo okhoyo wenkqubo yokugcina amandla ngaphezulu kwe-20% kumjikelo wobomi bonke.3

• Kuyilo lombane lwenkqubo yokugcina amandla, ukuhlawuliswa kunye nokulawulwa kokukhutshwa kweqela ngalinye leebhetri zenziwa ngokwahlukileyo, kwaye amaqoqo ebhetri awaxhunyiwe ngokufanayo, ekhusela ingxaki yokujikeleza okubangelwa uxhulumaniso oluhambelanayo lwe-DC, kwaye iphucula ngempumelelo umthamo okhoyo wenkqubo.4

• Ulawulo oluchanekileyo lobushushu ukwandisa ubomi benkqubo yokugcina amandla

Ubushushu beseli nganye nganye buqokelelwa kwaye bubekwe iliso ngexesha lokwenyani.Ngokusebenzisa ukulinganisa ubushushu beCFD enemigangatho emithathu kunye nesixa esikhulu sedatha yovavanyo, uyilo lwe-thermal lwenkqubo yebhetri luphuculwe, ukuze umahluko omkhulu wobushushu phakathi kweeseli enye yenkqubo yebhetri ungaphantsi kwe-5 ° C, kwaye ingxaki Ukwahlulwa kweseli enye okubangelwa kukungahambelani kobushushu kusonjululwe.5

Ufuna ukuvelisa ibhetri ye-lithium elungiselelwe ngokwemfuneko ekhethekileyo, wamkelekile ukudibana neqela le-LIAO ukuze ufumane iinkcukacha ezithe vetshe.
