Ukwandisa isikhathi sokuphila nokusebenza kwamabhethri e-lithium-ion, imikhuba yokushaja efanele ibalulekile. Ucwaningo lwakamuva nezincomo zemboni zigqamisa amasu okushaja ahlukile ezinhlobo ezimbili zebhethri ezisetshenziswa kabanzi: amabhethri e-Nickel-Cobalt-Manganese (NCM noma i-ternary lithium) namabhethri e-Lithium Iron Phosphate (LFP). Nakhu abasebenzisi okudingeka bakwazi:
Izincomo Ezibalulekile
- Amabhethri e-NCM: Khokhisa ku90% noma ngaphansiukusetshenziswa kwansuku zonke. Gwema izindleko ezigcwele (100%) ngaphandle uma kunesidingo ohambweni olude.
- Amabhethri e-LFP: Ngenkathi ushaja nsuku zonke ku90% noma ngaphansikuhle, amasonto onke ngokugcwele
- khokhisa(100%) kuyadingeka ukuze kulungiswe kabusha isilinganiso Sesimo Senkokhelo (SOC).
Kungani Ugwema Ukukhokhiswa Okugcwele Kwamabhethri e-NCM?
1. Ukucindezeleka Okunamandla Kagesi Kusheshisa Ukuwohloka
Amabhethri e-NCM asebenza ngomkhawulo ophezulu wamandla kagesi uma kuqhathaniswa namabhethri e-LFP. Ukushaja ngokugcwele lawa mabhethri kuwabeka emazingeni aphakeme kagesi, kusheshisa ukusetshenziswa kwezinto ezisebenzayo ku-cathode. Le nqubo engenakuhlehliswa iholela ekulahlekelweni kwamandla futhi ifinyeze impilo yonke yebhethri.
2. Izingozi Zokungalingani Kwamaseli
Amaphakethe ebhethri aqukethe amaseli amaningi anokungahambisani ngokwemvelo ngenxa yokuhlukahluka kokukhiqiza kanye nokungafani kwe-electrochemical. Uma eshaja kufika ku-100%, amaseli athile angase ashaje ngokweqile, abangele ingcindezi yendawo kanye nokuwohloka. Nakuba Amasistimu Okuphatha Ibhethri (BMS) esebenza ngokulinganisela ukulinganisa amandla kagesi, ngisho namasistimu athuthukile avela kumikhiqizo ehamba phambili efana ne-Tesla ne-BYD awakwazi ukuqeda le ngozi ngokugcwele.
3. Izinselele Zezilinganiso Ze-SOC
Amabhethri e-NCM abonisa ijika likagesi elingumqansa, elivumela ukulinganisa okunembe ngokuqhathaniswa kwe-SOC ngendlela ye-open-circuit voltage (OCV). Ngokuphambene, amabhethri e-LFP agcina ijika lamandla kagesi elicishe libe isicaba phakathi kuka-15% no-95% we-SOC, okwenza ukufundwa kwe-SOC okusekelwe ku-OCV kungathembeki. Ngaphandle kwamashaji agcwele ezikhathi ezithile, amabhethri e-LFP alwela ukulinganisa kabusha amanani awo e-SOC. Lokhu kungaphoqa i-BMS ukuthi ibe ezindleleni zokuvikela ezivamile, ukuphazamisa ukusebenza nempilo yebhethri yesikhathi eside.
Kungani Amabhethri e-LFP Edinga Izindleko Ezigcwele Zamasonto onke
Inkokhelo yamasonto onke engu-100% yamabhethri e-LFP isebenza "njengokusetha kabusha" i-BMS. Le nqubo ibhalansisa ama-voltage amaseli futhi ilungisa ukunemba kwe-SOC okubangelwa iphrofayili yawo kagesi ezinzile. Idatha enembile ye-SOC ibalulekile ukuze i-BMS isebenzise izinyathelo zokuvikela ngempumelelo, njengokuvimbela ukuchithwa ngokweqile noma ukuthuthukisa imijikelezo yokushaja. Ukweqa lokhu kulinganisa kungase kubangele ukuguga ngaphambi kwesikhathi noma ukwehla kokusebenza okungalindelekile.
Imikhuba Engcono Kakhulu Yabasebenzisi
- Abanikazi Bebhethri le-NCM: Beka kuqala izinkokhiso ezingaphelele (≤90%) futhi ugcine izindleko ezigcwele ngezidingo zezikhathi ezithile.
- Abanikazi Bebhethri le-LFP: Gcina ukushaja kwansuku zonke kungaphansi kuka-90% kodwa qinisekisa umjikelezo wenkokhiso wangeviki ogcwele.
- Bonke Abasebenzisi: Gwema ukukhishwa okujulile okuvamisile kanye nezinga lokushisa elidlulele ukuze uthuthukise impilo yebhethri.
Ngokusebenzisa lawa maqhinga, abasebenzisi bangathuthukisa kakhulu ukuqina kwebhethri, banciphise ukuwohloka kwesikhathi eside, futhi baqinisekise ukusebenza okuthembekile kwezimoto zikagesi noma amasistimu okugcina amandla.
Hlala unolwazi ngezibuyekezo zakamuva zobuchwepheshe bebhethri nezinqubo zokusimama ngokubhalisela iphephandaba lethu.
