Ngokwesikhulumi ochungechungeni lwamabhethri, “Ubuhlakani bokwenziwa busebenzisa ibhethri, okuyisilwane sasendle.”Kunzima ukubona izinguquko ebhethrini njengoba lisetshenziswa;kungakhathaliseki ukuthi ishajwe ngokuphelele noma ayinalutho, iyintsha noma igugile futhi idinga ukushintshwa, ibonakala ifana njalo.Ngokuphambene, isondo lemoto lizogogeka lapho umoya uphansi futhi liyobonisa ukuthi seliphelile ukuphila lapho amateyiti egqokwa.

Izinkinga ezintathu zifingqa izithiyo zebhethri: [1] umsebenzisi akanasiqiniseko sokuthi iphakethe lisele isikhathi esingakanani;[2] umsingathi akanaso isiqiniseko sokuthi ibhethri lingahlangabezana yini nesidingo samandla;futhi [3] ishaja idinga ukulungiselelwa usayizi webhethri ngalinye kanye nekhemistri.Ibhethri "elihlakaniphile" lithembisa ukubhekana nokunye kwalokhu kushiyeka, kodwa izixazululo ziyinkimbinkimbi.

Abasebenzisi bamabhethri ngokuvamile bacabanga ngephakethe lebhethri njengesistimu yokugcina amandla ekhipha uphethiloli owuketshezi njengethangi likaphethiloli.Ibhethri lingabukwa linjalo ukuze kube lula, kodwa ukulinganisa amandla agcinwe kudivayisi ye-electrochemical kunzima kakhulu.

Njengoba ibhodi lesifunda eliphrintiwe elilawula ukusebenza kwebhethri ye-lithium likhona, i-lithium ithathwa njengebhethri elihlakaniphile.Noma kunjalo ibhethri le-asidi eholayo evalekile alinakho ukulawula kwebhodi lokuthuthukisa ukusebenza kwalo.

Liyini ibhethri elihlakaniphile?

Noma yiliphi ibhethri elinesistimu yokulawula ibhethri eyakhelwe ngaphakathi lithathwa njengelihlakaniphile.Ivamise ukusetshenziswa kumagajethi ahlakaniphile, okuhlanganisa njengamakhompuyutha nezinto zikagesi eziphathwayo.Ibhethri elihlakaniphile liqukethe isifunda se-elekthronikhi ngaphakathi nezinzwa ezingaqapha izici ezifana nempilo yomsebenzisi kanye namaleveli kagesi kanye namanje futhi idlulisele lokho kufundwa kudivayisi.

Amabhethri ahlakaniphile anekhono lokubona isimo sawo sokushaja kanye nemingcele yesimo sezempilo, idivayisi engafinyelela kuyo ngoxhumo lwedatha olukhethekile.Ibhethri elihlakaniphile, ngokungafani nebhethri elingahlakaniphile, lingaxhumana nalo lonke ulwazi olubalulekile kudivayisi nakumsebenzisi, linikeze amandla okwenziwa izinqumo ezifanele.Ibhethri elingahlakaniphile, ngakolunye uhlangothi, alinayo indlela yokwazisa idivayisi noma umsebenzisi mayelana nesimo sayo, okungaholela ekusebenzeni okungalindelekile.Isibonelo, ibhethri lingaxwayisa umsebenzisi uma lidinga ukushajwa noma lapho selisondele ekupheleni kwempilo yalo noma lilimele nganoma iyiphi indlela ukuze kuthengwe elinye elingena esikhundleni.Ingase futhi yazise umsebenzisi uma idinga ukushintshwa.Ngokwenza lokhu, ukungaqiniseki okukhulu okulethwa amathuluzi amadala—angase angasebenzi kahle ngezikhathi ezibalulekile—kungagwenywa.

Ukucaciswa kwebhethri elihlakaniphile

Ukuze kuthuthukiswe ukusebenza komkhiqizo, ukuphepha, nokusebenza kahle, ibhethri, ishaja ehlakaniphile, nedivayisi yomsingathi konke kuyaxhumana.Isibonelo, ibhethri elihlakaniphile lidinga ukushajwa lapho kudingekile kunokuba lifakwe kusistimu yomsingathi ukuze kusetshenziswe amandla njalo nangokungaguquguquki.Amabhethri ahlakaniphile ahlala eqapha umthamo wawo lapho eshaja, eshajwa, noma egcina.Ukuze kutholwe izinguquko kuzinga lokushisa kwebhethri, izinga lokushaja, izinga lokuphuma, njll., igeji yebhethri isebenzisa izinto ezithile.Amabhethri ahlakaniphile ngokuvamile anezici zokuzilinganisa nezici eziguquguqukayo.Ukusebenza kwebhethri kuzolinyazwa ukugcinwa kokushajwa okugcwele.Ukuze kuvikelwe ibhethri, ibhethri elihlakaniphile lingadonsa amandla okugcina amandla njengoba kudingeka futhi livule umsebenzi wokulondoloza ohlakaniphile uma kudingeka.

Ngokwethulwa kwamabhethri ahlakaniphile, abasebenzisi, okokusebenza, nebhethri konke kungaxhumana.Abakhiqizi nezinhlangano ezilawulayo ziyahluka endleleni ibhethri “ehlakaniphe” ngayo.Ibhethri elihlakaniphile elibaluleke kakhulu lingafaka kuphela i-chip eyala ishaja yebhethri ukuthi isebenzise i-algorithm yokushaja efanele.Kodwa, Iforamu ye-Smart Battery System (SBS) ngeke ikubheke njengebhethri elihlakaniphile ngenxa yesidingo sayo sezinkomba ezisezingeni eliphezulu, ezibalulekile kumishini yezokwelapha, yezempi, neyekhompyutha lapho kungeke kube khona indawo yephutha.

Ubuhlakani besistimu kufanele buqukethwe ngaphakathi kwephakethe lebhethri ngenxa yokuphepha kungenye yezinto eziyinhloko ezikhathazayo.I-chip elawula ukushajwa kwebhethri isetshenziswa ibhethri le-SBS, futhi isebenzisana nayo ngeluphu evaliwe.Ibhethri yekhemikhali ithumela amasignali e-analogue eshajani ayiyalela ukuthi iyeke ukushaja uma ibhethri seligcwele.Kungezwe inzwa yokushisa.Abakhiqizi abaningi bebhethri abahlakaniphile namuhla bahlinzeka ngobuchwepheshe begeji likaphethiloli olwaziwa nge-System Management Bus (SMBus), obuhlanganisa ubuchwepheshe be-chip yesekethe (IC) kumasistimu wocingo olulodwa noma izintambo ezimbili.

I-Dallas Semiconductor Inc. yethule i-1-Wire, isistimu yokulinganisa esebenzisa intambo eyodwa ekuxhumaneni kwesivinini esiphansi.Idatha newashi kuhlanganiswe futhi kuthunyelwe ngomugqa ofanayo.Ekupheleni kokwamukela, ikhodi yaseManchester, eyaziwa nangokuthi ikhodi yesigaba, ihlukanisa idatha.Ikhodi yebhethri nedatha, efana ne-voltage yayo, yamanje, izinga lokushisa, nemininingwane ye-SoC, igcinwa futhi ilandelelwa nge-1-Wire.Emabhethri amaningi, intambo ehlukile ezwa izinga lokushisa isetshenziswa ngezinjongo zokuphepha.Uhlelo luhlanganisa ishaja kanye nephrothokholi yayo.Kusistimu yocingo olulodwa lwe-Benchmarq, ukuhlolwa kwesimo sezempilo (SoH) kudinga "ukushada" idivayisi yomsingathi ebhethrini layo elinikeziwe.

I-1-Wire icela amasistimu okugcina amandla abambezelekile njengebhethri yesithwebuli sebhakhodi, amabhethri omsakazo wezindlela ezimbili, namabhethri ezempi ngenxa yezindleko zayo eziphansi zehadiwe.
