Ukuba izibane zesitalato zelanga zisebenzisa iibhetri ze-lithium, zinokwandiswa njani ixesha lazo lokuphila? TIANXIANG, ingcaliUmvelisi wezibane zesitalato zelanga waseTshayina, ichaza izisombululo.
1. Thintela ukutshaja kakhulu kweebhetri zeLithium zezibane zesitalato zelanga
Ubomi kunye nokusebenza kweebhetri zezibane zesitalato zelanga kunxulumene kakhulu nokuqokelelana kobushushu ngaphakathi kwebhetri. Umthombo ophambili wobushushu kukulahleka kwamandla okuvela kwiimpendulo zangaphakathi ze-electrochemical, ezinokubonwa nje njengemveliso ye-voltage yokutshaja kunye ne-charging current. Ubushushu obuninzi buveliswa kwi-oxygen recombination reaction njengoko i-float current inyuka. Ubushushu buyanda njengoko i-float current inyuka ngexesha lokutshaja i-voltage engaguqukiyo. Ngenxa yendlela iibhetri ezivaliweyo ezilawulwa yivalvu ezakhiwe ngayo, i-thermal runaway yinto ekhethekileyo. I-thermal runaway idla ngokubangela umonakalo omkhulu, kubandakanya ukulahleka kwamanzi kwibhetri kunye nokudumba kwe-casing, kwaye kwiimeko ezinzima, yenza ibhetri ingasetyenziswa. Amaxabiso e-charging voltage achazwe kwimiyalelo yomenzi we-solar streetlight kufuneka alandelwe ngokusondeleyo ukuze kuthintelwe ukutshaja kakhulu. Izixhobo zamandla ezidibeneyo zanamhlanje zinokucwangciswa kwaye zilawulwe ngobuchule. Kubalulekile ukuqinisekisa uqwalaselo oluchanekileyo kwaye abasebenzi abangagunyaziswanga abazitshintshi ngokuzithandela izicwangciso.
2. Ukuthintela ukutshaja okunganelanga kweebhetri zeLithium zezibane zesitalato zelanga
Ukungatshaji ngokwaneleyo, ngokuchaseneyo nokutshaja kakhulu, ikakhulu kubangelwa kukuseta i-voltage yokutshaja ephantsi kakhulu okanye ephantsi kakhulu. Kusenokuba kungenxa yengxaki kwinkqubo ye-rack.
3. Ukuthintela ukukhupha kakhulu iibhetri zeLithium zezibane zesitalato zelanga
Ubunzulu bokukhupha bunxulumene kakhulu nokubalwa komjikelo wokukhupha ibhetri oyilwe yibhetri (ubude bobomi). Umzekelo, ubunzulu bokukhupha obuyi-5% buhambelana nemijikelo eyi-10,000, ngelixa ubunzulu obuyi-50% bokukhupha buphumela kwimijikelo engama-800 kuphela. Ukukhupha ibhetri kakhulu kunokuthintela ibhetri ukuba iphinde isebenze kwimeko yayo efanelekileyo, okanye kuyenze ingasebenzi. Amanqanaba ahlukeneyo okukhupha abangela amaxesha ahlukeneyo okukhupha kunye neevolthi zokuphelisa, kunye namandla ahlukeneyo asebenzayo, kwaye achaphazeleka bubushushu obuphakathi. Iigophe ezinxulumeneyo azidweliswanga okanye zidwetshwe apha; zibonelelwa kwiincwadi zebhetri zabavelisi abahlukeneyo. Abasebenzi bokulungisa kufuneka banikele ingqalelo kwezi kwaye banamathele ngokungqongqo kwizicwangciso zedatha ezifanelekileyo kwiyunithi yokubeka iliso, bephepha utshintsho olungenanjongo. Abavelisi bamandla erakhi yanamhlanje bayila imisebenzi yokucima ibhetri, benqumla ngokuzenzekelayo isekethe yokukhupha ibhetri ngemiyalelo yokubeka iliso xa ibhetri yesibane sesitalato selanga ikhupha kwivolthi yokuphelisa emiselweyo. Abanye abavelisi bade bafaka nesekethe yokuqhawula enyanzelekileyo endaweni ukuthintela iyunithi yokubeka iliso ekufumaneni ivolthi yokuphelisa ibhetri okanye ukukhupha imiyalelo ngenxa yeemeko ezingalindelekanga (kuxhomekeke kumbane wayo). Ngenxa yoko, ngexesha lokuhlolwa rhoqo kunye nokuhlolwa okufunekayo kunye nokugcinwa, abasebenzi bolondolozo kufuneka bagxile ekuthembekeni kweesekethe zehardware.
4. Ukulawula iMozulu yangaphandle
Ukwanda kombane ohambayo, ukuncipha kokumelana kwangaphakathi, kunye nokwanda komsebenzi we-electrolyte konke oku kubangela ukugqwala okukhawulezileyo kwezinto eziqhubayo kunye nobomi obufutshane xa ubushushu bebhetri bunyuka. Amandla ebhetri okukhupha umthwalo ayancipha xa umsebenzi we-electrolyte wehla kuba ukumelana kwangaphakathi kuyehla. Ke ngoko, ukujonga ubushushu bebhetri yesibane sesitalato selanga kunye nokulawula nokugcina ubushushu bomoya obujikelezileyo kubalulekile. Ukubuyiselwa kobushushu be-voltage yokutshaja nako kuyimfuneko ukuze kuthintelwe ukutshaja kakhulu kubushushu obuphezulu kunye nokutshaja ngaphantsi kubushushu obuphantsi. Kwiindawo ezininzi usebenzisa iipakethi zebhetri, ubushushu be-ambient bulawulwa malunga nama-25 degrees Celsius. Uvavanyo lobomi olukhawulezileyo lubonisa ukuba ukunyuka kwe-10 degrees Celsius kubushushu be-ambient ngaphandle kokulungisa i-voltage yokutshaja kuya kunciphisa ubude bebhetri ye-lithium yesibane sesitalato selanga.
5. Izibane zesitalato zelanga zifuna ukutshintshwa kweebhetri ezingasebenzi kakuhle ngexesha elifanelekileyo
Ngenxa yokwahluka kwenkqubo yokwenziwa kweseli nganye nganye, ukutshaja okudadayo ixesha elide kunokubangela ukuba "zishiyeke ngasemva" kancinci kancinci. Ukuze kuphinde kusebenze iiseli ezisaleleyo kwaye zingaphindi zibuyele umva, iyunithi yokubeka iliso inomsebenzi wolawulo otshaja ibhetri rhoqo kusetyenziswa i-equalization. Nangona kunjalo, ibhetri enesiphene ekugqibeleni inokubangelwa kukushiyeka okungapheliyo. Umthamo webhetri unokuvavanywa ngokwahlukeneyo okanye ukumelana kwayo kwangaphakathi kunokuvavanywa kwi-intanethi, phakathi kwezinye iindlela, ukuqinisekisa ukuba ibhetri ayinakulungiswa na. Eyona nto ibalulekileyo kukutshintsha iibhetri ezinesiphene ngokukhawuleza, njengoko oku kubalulekile ekufumanekeni nasekuphileni ubomi bebhetri.iibhetri ze-lithium zesibane sesitalato selangaiphakheji.
