Kuzinhlelo zebhethri ye-lithium, ukunemba kwesilinganiso se-SOC (State of Charge) isilinganiso esibalulekile sokusebenza Kwesistimu Yokulawula Ibhethri (BMS). Ngaphansi kwezimo zokushisa ezihlukene, lo msebenzi uba inselele nakakhulu. Namuhla, singena emcabangweni ocashile kodwa obalulekile wezobuchwepheshe—i-zero-drift current, okuthinta kakhulu ukunemba kokulinganisa kwe-SOC.
Iyini I-Zero-Drift Yamanje?
I-Zero-drift current isho isignali yamanje engamanga ekhiqizwa isekethe ye-amplifier uma ikhonaokokufaka okuyiziro okwamanje, kodwa ngenxa yezici ezifanaukushintsha kwezinga lokushisa noma ukungazinzi kokunikezwa kwamandla, indawo yokusebenza emile ye-amplifier iyashintsha. Lolu shintsho luyakhula futhi lubangele okukhiphayo ukuthi kuchezuke kunani elihlosiwe elinguziro.
Ukukuchaza kalula, cabanga ngezikali zokugezela ezidijithali ezibonisayoIsisindo esingu-5 kg ngaphambi kokuba noma ubani anyathele kuso. Leso sisindo “sesipoki” silingana ne-zero-drift current—uphawu olungekho ngempela.
Kungani Kuyinkinga Ngamabhethri e-Lithium?
I-SOC kumabhethri e-lithium ivame ukubalwa kusetshenziswaukubala kwe-coulomb, ehlanganisa yamanje ngokuhamba kwesikhathi.
Uma i-zero-drift yamanje ingu-zerookuhle nokuphikelelayo, kungasephakamisa i-SOC ngamanga, ukukhohlisa isistimu ukuthi icabange ukuthi ibhethri ishajwe kakhulu kunalokho eyikho ngempela—mhlawumbe inqamule ukushaja ngaphambi kwesikhathi. Ngokuphambene,i-negative driftkungaholela kui-SOC ebukelwa phansi, okubangela ukuvikeleka kokukhishwa ngaphambi kwesikhathi.
Ngokuhamba kwesikhathi, lawa maphutha anqwabelene anciphisa ukuthembeka nokuphepha kwesistimu yebhethri.
Nakuba i-zero-drift current ingenakuqedwa ngokuphelele, ingancishiswa ngempumelelo ngenhlanganisela yezindlela:
- Ukulungiselela izingxenyekazi zekhompuyutha: Sebenzisa i-low-drift, i-op-amps enembayo ephezulu kanye nezingxenye;
- Isinxephezelo se-algorithmic: Lungisa ngamandla ukuze ukhukhuleke usebenzisa idatha yesikhathi sangempela njengezinga lokushisa, i-voltage, kanye nesimanje;
- Ukuphatha okushisayo: Lungiselela ukwakheka nokukhipha ukushisa ukuze unciphise ukungalingani kokushisa;
- Inzwa yokunemba okuphezulu: Thuthukisa ukunemba kokutholwa kwepharamitha ebalulekile (i-voltage yeseli, i-voltage yephakethe, izinga lokushisa, lamanje) ukuze unciphise amaphutha okulinganisa.
Sengiphetha, ukunemba kukho konke ukubalwa kwe-microamp. Ukubhekana ne-zero-drift current kuyisinyathelo esibalulekile sokwakha amasistimu okuphatha amabhethri ahlakaniphile nathembekile.
