Ukubaluleka kokuphathwa kwebhethri kuye kwabonakala. Imikhiqizo eminingi iqhubekela ezindleleni eziphathwayo, isebenzisa ukuzimela okungakaze kubonwe ngaphambili. Ngaphambi kweminyaka engamashumi amabili edlule, ucingo olungenantambo lwaqale lwanikeza inkululeko yokuhamba ekhaya.

Manje, imikhiqizo ephathekayo ephinde ishajwe yenza abantu bahlale bexhumene nemindeni yabo ngenkathi abantu behamba. Imikhiqizo eminingi isebenzisa amabhethri aphinde ashajwe, futhi ngokuncipha kwevolumu yomkhiqizo, ubunkimbinkimbi bale mikhiqizo buthuthuka njalo. Ibhethri elishajayo ngokwalo liyashintsha, abakhiqizi bebhethri balwela ukwethula imikhiqizo emisha evumelana nezimakethe ezishintsha ngokushesha.

I-voltage yebhethri iyengezwa, ukucaciswa komumo kuyashintshwa, futhi ukuminyana kwamandla nakho kuyakhuphuka. Ukuqonda kwabathengi ngebhethri nakho kujulile, kufanele babe nezimo eziguquguqukayo, amahora amade okusebenza, izindleko eziphansi kanye nokuvikeleka okuphezulu. I-Microchip ibisebenza kanzima ukwenza lula ukuklama kwesistimu ngezilawuli ezincane ze-PIC iminyaka eminingi.

Njengamanje, i-Microchip isebenzisa lobu buchwepheshe emugqeni womkhiqizo wokuphathwa kwebhethri ukwenza lula nokuphatha kangcono uhlelo lokushaja. Indlela Okokuqala, uhlelo lokuphatha ibhethri olujwayelekile luhlukaniswe ngamamojula amane okushaja, ukuvikela, ukukalwa kukagesi, nokuphepha: 1. Iphakethe lebhethri elisuselwe kwibhethri lesibili lihlukile kwiphakethe lebhethri, futhi iphakethe lebhethri lesibili liyashajwa ngemva kokusetshenziswa.

Esikhundleni sokulahlwa njengebhethri. Izinhlobo nama-algorithms wokushaja wesekethe yokushaja kuyahlukahluka, futhi ashajwa ngokufanelekile ngezinhlobo ezithile zamakhemikhali zamabhethri. Indawo yeshaja kufanele futhi ikhethwe ngendlela efanele.

Ishaja iyiyunithi ezimele yodwa: iyinkokhelo eqondile yesiguquli noma ngesiguquli; ishaja ihlanganiswe ohlelweni noma ngaphakathi kwephakethe lebhethri; okunye okucatshangelwayo okubalulekile kuhlanganisa isikhathi sokushaja, izinga lokushisa nezimfuneko zomsindo. I-Microchip ihlinzeka ngemikhiqizo ehlukahlukene yokuphatha ukushaja kumashaja alayini wephakethe lebhethri le-lithium ion eyodwa noma eliphindwe kabili / le-polymer. Umsindo ophumayo weshaja yomugqa uphansi, okubaluleke kakhulu kulabo abathumela futhi bamukele izwi nedatha.

Idizayinelwe ukusebenza kahle okuphezulu, isilawuli sokushaja semodi yokushintsha ye-PS200 kufika ku-1MHz. Ihlanganisa i-algorithm yokushaja amabhethri e-lithium ion, amabhethri e-nickel namabhethri e-lead-acid. Njengoba ukuklanywa kweshaja yokushintsha kuyinkimbinkimbi kakhulu, i-Microchip inikeze amathuluzi esofthiwe ukuqondisa abaklami ukwenza ukucushwa kwe-IC kanye nemidwebo yesekethe.

Embonini evamile ehlinzekwa kumkhiqizo weshaja, esinye isisombululo ukusebenzisa imitha kagesi IC nesilawuli sokushaja. I-PS501 inomjikelezo wokushaja we-pulse ukulawula okokufaka / okukhiphayo kwendawo yonke, engafinyelela le mfuneko. Le topology inikeza isisombululo esihlangene kakhulu futhi esingabizi kakhulu.

Ingxenye yokushaja yesistimu iyahlukaniswa, futhi i-Microchip ine-algorithm efiselekayo yokuthuthukisa ukushaja, okuhlanganisa ukukhulisa umthamo wokushaja, ukunciphisa isikhathi sokushaja, nokwenza amakhasimende afinyelele ukwaneliseka okungcono kakhulu. 2. Ukuvikela Uma usebenzisa ibhethri ye-lithium ion/polymer, isivikelo kufanele sinikezwe ngoba ukushajwa ngokweqile noma ukushisa ngokweqile kungabangela umlilo noma ukuqhuma.

Amabhethri aneasidi yomthofu noma amabhethri e-nickel awadingi ukuvikelwa, kodwa ngokuvamile ahlinzekwa ukuze kuvikelwe ukujikeleza ukuze kuvinjelwe ukulimala noma ukuwohloka kwebhethri. Isekhethi enkulu yokuvikela iyisekhethi ezinikele ukuthola ukuthi ngabe isimo esingaphephile senzekile yini futhi nephakethe lebhethri liyavalwa ukuze kuvinjwe umonakalo lapho kutholwa isimo esingaphephile. Isekhethi yokuvikela yesibili ivimbela ibhethri ukuthi ingaqhubeki nokushaja kanye / noma ukuphuma ngaphansi kwesimo esingaphephile.

Uma kwenzeka ukwehluleka kwesekethe yokuvikela eyinhloko, inganikeza ukuvikelwa kokulondoloza isekethe yesibili. Umsebenzisi angakwazi futhi ukwengeza izinga elisha lokuvikela, elifana namafusi amakhemikhali, futhi amafuse amakhemikhali angavalwa unomphela lapho ukuvikela okunye kwehluleka. I-IC yokuvikeleka ezinikele ivamise ukusetshenziselwa ukujikeleza okuyinhloko kokuvikela.

Ngokuphathelene nokuvikela kwesibili namasekhethi okuvikela ukuzinza, i-IC yokuphatha ibhethri ilungile, ngoba ayingezi izindleko zezixazululo. Imitha kagesi ye-MICORCHIP, efana ne-PS501 ne-PS810, ingaqapha i-voltage, i-voltage yephakethe lebhethri, yamanje kanye nezinga lokushisa lebhethri ngalinye. Iphinikhodi ye-Universal Input/Output (GPIO) inemisebenzi yokumisa enamandla, ukumisa, nokusetha kabusha noma yiziphi izimo ezingaba khona zenani likagesi.

Lokhu kuvumelana nezimo kuvumela imitha kagesi ukuthi ihlangabezane nezidingo zokuphepha eziyinkimbinkimbi kakhulu. 3. Inani lemitha kagesi alikona nje ukuqapha ukugeleza kwamanje kuphakethe lebhethri.

Ukulinganisa amandla okunembe kufanele kube indlela yohlelo, ecubungula kabanzi izindlela ezijwayelekile, imvelo kanye nokulindelwe ngamakhasimende. Ngokufanelekile, i-IC yokuphatha ibhethri inganikeza ukusebenza okuhle kokusebenza kumsebenzisi, kuyilapho ihlinzeka ngolwazi oludingekayo kusistimu ukuze yenze ukukhetha okuhlakaniphile ukuthuthukisa ukusebenza kwesistimu. Ama-algorithms okulinganisa ugesi ahlakaniphile anganweba isikhathi sokusebenza kwesistimu nempilo yebhethri, futhi anikeze ukuvikeleka okwengeziwe ngokuthola ngokunembile ukushajwa okugcwele nendawo yokukhipha egcwele.

Ziphinde zithole futhi zivimbele ukungalingani kwebhethri kanye nokushisa ngokweqile. Lawa ma-algorithms angalungiswa ngokuya ngezimo zesistimu futhi anganciphisa ukuguga kwebhethri. Basebenzisa imodeli elungisekayo yokuziphatha kwebhethri ukuze baqinisekise ukuthi ukulahlekelwa okubangelwa ukuzikhipha ngokwawo kanye nokushaja ngendlela efanele.

Lawa ma-algorithms angenziwa ngokwezifiso amakhasimende ukuze abasebenzisi bamukele ulwazi oluhlobene kuphela, kodwa ungakhathazeki ngokuvala shaqa ngephutha okungaholela ekulahlekeni kwedatha. Imitha yamandla ye-Microchip ithuthukise ukusebenza, okwenza ukulinganisa kwamandla kuthembeke kakhulu. Ukuvalwa kwengozi yesistimu kungenye yezinto ezingajabulisi uma usebenzisa amadivaysi aphathekayo, abantu abaningi kufanele bazizwe ngendlela efanayo.

Kuzonciphisa ukwaneliseka kwamakhasimende, futhi kuzodala ukulahleka kwedatha okubalulekile nesikhathi nemali. Ukuvala shaqa okungalindelekile ngokuvamile kwenzeka lapho i-voltage yebhethri yehlela ohlelweni lokusekela olungezansi. Uma umthwalo ungeziwe, i-voltage yebhethri izokwehla, ikakhulukazi lapho umugqa wokukhipha uzophela, umthambeko wejika lokukhipha ungeziwe.

Ukuze uvimbele ukuvala shaqa ngephutha, i-Microchip isebenzisa i-algorithm esekelwe olwazini lwesidingo samandla lapho kuvalwa, njengoba kuboniswe ngezansi. Imitha yamandla ikhetha ngokuzenzakalelayo indawo yokuvala shaqa efanelekile ukuze kuqinisekiswe ukuthi isexwayiso sezindaba zamandla ayinsalela eyanele futhi ilondoloza idatha kumsebenzisi. Ngokuhamba kwesikhathi, izindawo zokuvala zizoshintsha.

Ngokuguga kwebhethri, umthamo ogcwele wehliswa, i-voltage yejika lokuphuma nayo iyashintsha. I-algorithm yokuguga ingalungisa indawo yokuvala ukuze kuqinisekiswe ukuthi amandla azomoshakala ngokuguga kwebhethri. 4.

Isistimu enephakethe lebhethri elikhiphekayo kufanele isebenzise izinyathelo zokuphepha ukuze ivikele isistimu ukuthi isebenze ngaphansi komklamo webhethri ongenangqondo. Uma isistimu isebenzisa amaseli ekhemikhali angahlelekile, ukweqisa noma ukugqagqana kungase kubangele izimo ezingaphephile. Uma ungasebenzisi amaseli ekhemikhali anesimo esimeme ngokuhambisana nezidingo zomkhiqizi, kungase kubangele ukwehla kokusebenza kanye nempilo efinyeziwe.

Isithiyo samanje semishini esilula sisetshenziswa njengamanje, njengokucaciswa komumo ohlukile noma isixhumi, kanye nophawu lokufunda uphawu oluvela ebhethrini. Kodwa ngeshwa, lezi zinyathelo zokuphepha ziphulwa kalula. Abasebenzisi abafuna ngempela isisombululo sezinga lesistimu esivumelana nezimo esiqinisekisa ukuphepha komsebenzisi, sithuthukise ukusebenza kwesistimu, futhi sinikeze ukwethembeka kwesikhathi eside.

I-Microchip inikeza isisombululo esihle sokuqinisekisa ibhethri, i-KeeloQ°I-algorithm yokubethela, le algorithm ecindezelwe yombhalo wekhodi engu-64-bit inganikeza Izingxenyekazi zekhompuyutha ze-algorithm ye-KEELOQ yezinhlelo zokusebenza ezihlukahlukene ezihlinzekwa yimboni, umsingathi kanye nama-peripherals. Namuhla, i-algorithm ye-KeeloQ isetshenziswe ezinhlelweni ezihlukahlukene zokuphepha, njengezinhlelo zokulawula ukufinyelela okubalulekile (izinhlelo zokusebenza ezibalulekile embonini yezimoto). Uma usebenzisa ubuchwepheshe be-KeeloQ ukuze kuqinisekiswe ibhethri, isistimu ingumsingathi, futhi ibhethri liyi-peripheral.

Uhlelo lugcina ikhodi yomkhiqizi kanye nejeneretha yenombolo engahleliwe. Uma ibhethri lenziwa, inombolo ye-serial ehlukile nokhiye kukhiqizwa futhi kugcinwe kumemori, futhi ngeke kushintshwe. Uma ibhethri lixhunywe kusistimu, isistimu icela inombolo ye-serial bese ithumela umpetha wamabhithi angu-32.

Ibhethri izohlinzeka ngenombolo ye-serial ehambisanayo futhi inikeze impendulo engamabhithi angama-32. Ngenxa yezinhlelo eziningi zokuphatha ibhethri, i-Microchip isebenzisa ubuchwepheshe be-KeelOQ emikhiqizweni yayo yokuphatha ibhethri kanye nama-microcontrollers amaningi e-PIC. Uma usebenzisa izikhathi zamandla e-Microchip kuphakethe lebhethri, asikho isidingo sezingxenyekazi zekhompuyutha ezengeziwe ukwenza ukuphepha kwesistimu kusebenze.

Uma ingekho imitha yamandla ephaketheni lebhethri, ungasebenzisa isilawuli esincane se-PIC njenge-KeeloQ hardware peripheral. Izingxenyekazi zekhompuyutha zokusingatha ezisekela ubuchwepheshe be-KeeloQ zihlanganisa amaphrosesa, amanani kagesi, namashaja. .
