Ukwandisa ixesha lokuphila kunye nokusebenza kweebhetri ze-lithium-ion, iindlela ezifanelekileyo zokutshaja zibalulekile. Izifundo zakutsha nje kunye nezindululo zeshishini ziqaqambisa iindlela zokutshaja ezahlukileyo kwiintlobo ezimbini zebhetri ezisetyenziswa ngokubanzi: iibhetri zeNickel-Cobalt-Manganese (NCM okanye i-ternary lithium) kunye neebhetri zeLithium Iron Phosphate (LFP). Nantsi into ekufuneka bayazi abasebenzisi:
Iingcebiso eziphambili
- Iibhetri zeNCM: Intlawulo ku90% okanye ngaphantsiukusetyenziswa kwansuku zonke. Ziphephe iintlawulo ezipheleleyo (100%) ngaphandle kokuba kuyimfuneko kwiihambo ezinde.
- Iibhetri zeLFP: Ngelixa ubiza yonke imihla ukuya90% okanye ngaphantsiilungile, angeveki epheleleyo
- intlawulo(100%) iyafuneka ukuze kuhlengahlengiswe uqikelelo lweState of Charge (SOC).
Kutheni Uthintelwa Iintlawulo ezipheleleyo zeebhetri zeNCM?
1. Uxinzelelo lombane oluphezulu lukhawulezisa ukuthotywa
Iibhetri ze-NCM zisebenza kumda wamandla aphezulu aphezulu xa kuthelekiswa neebhetri ze-LFP. Ukutshaja ngokupheleleyo ezi bhetri zixhomekeke kumanqanaba ombane aphakamileyo, kukhawulezisa ukusetyenziswa kwezinto ezisebenzayo kwi-cathode. Le nkqubo ingenakujikwa ikhokelela ekulahlekeni komthamo kwaye yenza bufutshane ubomi bebhetri bubonke.
2. Imingcipheko yokungalingani kweSeli
Iipakethi zebhetri zineeseli ezininzi ezinokungangqinelani kwendalo ngenxa yeeyantlukwano zemveliso kunye nokungafani kwe-electrochemical. Xa uhlawulisa kwi-100%, iiseli ezithile zinokuthi zigqithise, zibangele uxinzelelo lwendawo kunye nokuthotywa. Ngelixa iiNkqubo zoLawulo lweBattery (BMS) zilungelelanisa ngokusebenzayo ii-voltages zeseli, neenkqubo eziphambili ezivela kwiimpawu eziphambili ezifana neTesla kunye ne-BYD azinakuwuphelisa ngokupheleleyo lo mngcipheko.
3. Imingeni yoqikelelo lwe-SOC
Iibhetri ze-NCM zibonisa igophe lamandla ombane omnqantsa, nto leyo eyenza ukuba uqikelelo lwe-SOC luchaneke ngendlela yombane ovulekileyo (i-OCV). Ngokwahlukileyo, iibhetri ze-LFP zigcina ijika lamandla ombane eliphantse libe caba phakathi kwe-15% kunye ne-95% ye-SOC, okwenza ufundo lwe-SOC olusekwe kwi-OCV lungathembeki. Ngaphandle kweentlawulo ezigcweleyo zamaxesha ngamaxesha, iibhetri ze-LFP ziyasokola ukubuyisela amaxabiso azo e-SOC. Oku kunokunyanzelisa i-BMS kwiindlela zokukhusela rhoqo, ukuphazamisa ukusebenza kunye nempilo yebhetri yexesha elide.
Kutheni iibhetri ze-LFP zifuna iintlawulo ezigcweleyo ngeveki
Intlawulo yeveki ye-100% yeebhetri ze-LFP isebenza "njengokusetha kwakhona" kwi-BMS. Le nkqubo ilinganisa umbane weeseli kwaye ilungisa ukungachaneki kwe-SOC okubangelwa yiprofayili yabo yombane ozinzile. Idatha echanekileyo ye-SOC ibalulekile kwi-BMS ukwenza amanyathelo okukhusela ngokufanelekileyo, njengokuthintela ukukhutshwa ngokugqithiseleyo okanye ukulungelelanisa imijikelezo yokutshaja. Ukutsiba olu lungelelwaniso kunokukhokelela ekwaluphaleni kwangaphambi kwexesha okanye ukwehla komsebenzi okungalindelekanga.
Ezona Sebenziso zilungileyo zabasebenzisi
- Abanini Bebhetri yeNCM: Beka phambili iintlawulo ezingaphelelanga (≤90%) kwaye ugcine iintlawulo ezipheleleyo kwiimfuno zamaxesha athile.
- Abanini Bebhetri yeLFP: Gcina ukutshaja kwemihla ngemihla ngaphantsi kwe-90% kodwa qinisekisa umjikelo wentlawulo opheleleyo weveki.
- Bonke abasebenzisi: Kuphephe ukukhutshwa okunzulu rhoqo kunye namaqondo obushushu agqithisileyo ukwandisa ubomi bebhetri.
Ngokwamkela ezi zicwangciso, abasebenzisi banokwandisa kakhulu ukuqina kwebhetri, ukunciphisa ukuthotywa kwexesha elide, kunye nokuqinisekisa ukusebenza okuthembekileyo kwezithuthi zombane okanye iinkqubo zokugcina amandla.
Hlala unolwazi ngohlaziyo lwamva nje lwetekhnoloji yebhetri kunye nezenzo zozinzo ngokubhalisela kwincwadana yethu.
