Uma ukhetha ukuthenga amabhethri elanga e-lithium-ion, uzovame ukuhlangana namagama asetshenziswayo mayelana nokuphuma kwebhethri ye-lithium ngaphakathi kwesiqinisekiso sewaranti yomhlinzeki. Mhlawumbe lo mqondo uyinqaba kancane kuwe ovele uxhumane nebhethri ye-lithium, kodwa ngochwephesheumenzi webhethri yelangaI-BSLBATT, leli elinye lamagama ebhethri le-lithium esivame ukulisebenzisa, ngakho-ke namuhla ngizochaza ukuthi kuyini ukuphuma kwebhethri ye-lithium nendlela yokubala.Incazelo yebhethri ye-Lithium throughput:Ukuphuma kwebhethri le-lithium amandla aphelele angashajwa futhi ashajwe phakathi nayo yonke impilo yebhethri, okuyinkomba yokusebenza ebalulekile ebonisa ukuqina nempilo yebhethri. Ukwakhiwa kwebhethri ye-lithium, ikhwalithi yezinto ezisetshenziswayo, izimo zokusebenza (izinga lokushisa, izinga lokushaja/lokukhipha) kanye nesistimu yokuphatha konke kudlala indima ebalulekile kanye nomthelela ekuphumeni kwebhethri ye-lithium. Igama livame ukusetshenziswa kumongo wempilo yomjikelezo, okubhekisela enanini lemijikelezo yokushaja/yokukhipha ibhethri elingangena kuyo ngaphambi kokuba umthamo walo wehle kakhulu.Ukusebenza okuphezulu ngokuvamile kubonisa impilo yebhethri ende, njengoba kusho ukuthi ibhethri lingakwazi ukumelana nemijikelezo yokushaja/yokukhipha ngaphandle kokulahlekelwa umthamo omkhulu. Abakhiqizi bavamise ukucacisa impilo yomjikelezo olindelwe kanye nokusebenza kwebhethri ukuze kunikeze umsebenzisi umbono wokuthi ibhethri lizohlala isikhathi esingakanani ngaphansi kwezimo ezijwayelekile zokusebenza.Ngibala Kanjani Ukuphuma Kwebhethri Le-lithium?Ukuphuma kwebhethri le-lithium kungabalwa kusetshenziswa ifomula elandelayo:I- throughput (ihora le-Ampere noma ihora le-Watt) = Umthamo webhethri × Inani lemijikelezo × Ukujula kokukhishwa × Ukusebenza kahle komjikelezoNgokusho kwefomula engenhla, kungabonakala ukuthi inani eliphelele lebhethri ye-lithium lithinteka kakhulu ngenani lemijikelezo nokujula kokukhishwa. Ake sihlaziye izingxenye zale fomula:Inombolo Yemijikelezo:Lokhu kumelela inani eliphelele lemijikelezo yokushaja/yokukhipha ibhethri ye-Li-ion engayithola ngaphambi kokuba umthamo walo wehle kakhulu. Phakathi nokusetshenziswa kwebhethri, inani lemijikelezo lizoshintsha ngokuya ngezimo zemvelo ezihlukene (isb. izinga lokushisa, umswakama), amaphethini okusetshenziswa nemikhuba yokusebenza, ngaleyo ndlela kwenze ukuphuma kwebhethri le-lithium kube inani elishintshashintshayo.Isibonelo, uma ibhethri lilinganiselwe imijikelezo eyi-1000, inani lemijikelezo kufomula liyi-1000.Amandla ebhethri:Leli inani lesamba lamandla ibhethri elingawagcina, ngokuvamile likalwa ngamahora we-Ampere (Ah) noma ngama-Watt-hours (Wh).Ukujula Kokukhipha:Ukujula kokuchithwa kwebhethri le-lithium-ion izinga lapho amandla agciniwe ebhethri asetshenziswa noma akhishwa khona phakathi nomjikelezo. Ivamise ukuvezwa njengephesenti lengqikithi yomthamo webhethri. Ngamanye amazwi, ikhombisa ukuthi mangakanani amandla atholakalayo ebhethri asetshenziswayo ngaphambi kokuba ishajwe kabusha. Amabhethri e-lithium ngokuvamile akhishwa ekujuleni okungama-80-90%.Isibonelo, uma ibhethri ye-lithium-ion enamandla angu-100 amp-amahora ikhishwa kuya ku-50 amp-amahora, ukujula kokukhishwa kuzoba ngu-50% ngoba uhhafu womthamo webhethri usetshenzisiwe.Ukusebenza kahle Kokuhamba Ngebhayisikili:Amabhethri e-lithium-ion alahlekelwa inani elincane lamandla phakathi nomjikelezo wokushaja/wokukhipha. Ukusebenza kahle komjikelezo isilinganiso sokuphuma kwamandla ngesikhathi sokukhishwa kokokufaka kwamandla ngesikhathi sokushaja. Ukusebenza kahle komjikelezo (η) kungabalwa ngefomula elandelayo: η = ukuphuma kwamandla ngesikhathi sokukhipha/ukufakwa kwamandla ngesikhathi sokushaja × 100Eqinisweni, alikho ibhethri elisebenza kahle ngo-100%, futhi kukhona ukulahlekelwa kuzo zombili izinqubo zokushaja nokukhipha. Lokhu kulahlekelwa kungabangelwa ukushisa, ukumelana nangaphakathi, nokunye ukungasebenzi kahle ezinqubweni zebhethri zangaphakathi ze-electrochemical.Manje, ake sithathe isibonelo:Isibonelo:Ake sithi une10kWh BSLBATT ibhethri yodonga lwelanga, sibeka ukujula kokukhishwa ku-80%, futhi ibhethri linokusebenza kahle kwebhayisikili okungu-95%, futhi sisebenzisa umjikelezo owodwa wokushaja/wokukhipha ngosuku njengokujwayelekile, lokho ubuncane bemijikelezo engu-3,650 phakathi kwewaranti yeminyaka eyi-10.Okokusebenza = imijikelezo engu-3650 x 10kWh x 80% DOD x 95% = 27.740 MWh?Ngakho-ke, kulesi sibonelo, ukuphuma kwebhethri yelanga ye-lithium kungu-27.740 MWh. lokhu kusho ukuthi ibhethri izohlinzeka ngesamba samandla angu-27.740 MWh ngokushaja nokukhipha imijikelezo esikhathini sokuphila kwayo.Ukuphakama kwevelu yomthamo webhethri efanayo, kuyenza ibe yinde impilo yebhethri, okulenza libe yinketho ehlala isikhathi eside futhi enokwethenjelwa ezinhlelweni ezifana nokugcinwa kwelanga. Lesi sibalo sinikeza isilinganiso esiphathekayo sokuqina nokuhlala isikhathi eside kwebhethri, okusiza ukunikeza ukuqonda okuphelele kwezici zokusebenza kwebhethri. Ukuphuma kwebhethri le-lithium nakho kungenye yemibandela yereferensi yewaranti yebhethri.
