Ubuchwepheshe Bokushaja Okusheshayo Obunokutholwa Kokushisa Okuguquguqukayo
Ukwanda kwamadivayisi eselula—kusukela kuma-smartphone kuya kumathebulethi kuya kuma-laptop amancane—kubangela isidingo sokushaja okusheshayo kakhulu. Abasebenzisi bafuna amabhethri abo ashajwe ngemizuzu, hhayi amahora, ngaphandle kokubeka engcupheni impilo yebhethri noma ukuphepha kwedivayisi. Yilapho ubuchwepheshe bokushaja okusheshayo buqala khona ukusebenza. Kodwa-ke, isivinini esikhulu siletha inselele enkulu: ukushisa. Ukwanda kwamandla kagesi kanye ne-voltage kungakhuphula izinga lokushisa lamabhethri, izintambo, ama-adapter, ngisho nezingxenye zangaphakathi zedivayisi. Ukuze kuxazululwe le nselele, kuvela indlela yesimanje esetshenziswa kakhulu ngabakhiqizi: ukushaja okusheshayo ngokutholwa kokushisa okuguquguqukayo—uhlelo oluqapha izinga lokushisa ngesikhathi sangempela bese lulungisa isu lalo lokushaja ukuqinisekisa kokubili isivinini nokuphepha.
Kungani Ukushaja Okusheshayo Kukhulisa Izinga Lokushisa?
Empeleni, ukushaja okusheshayo kwandisa ukufakwa kwamandla kudivayisi. Amandla (P) angumkhiqizo we-voltage (V) kanye nowamanje (I): P = V × I. Ukuze ushaje ngokushesha, uhlelo luzokwandisa i-voltage, yamanje, noma kokubili. Lapho ugesi omkhulu ugeleza, ukushisa kukhiqizwa ngenxa yokumelana endleleni kagesi (ikhebula, isixhumi, isekethe yokushaja). Kalula nje, ukushisa okumelanayo kuhambisana nesikwele samandla kagesi: lapho ugesi uphakeme, kulapho ukushisa kukhiqizwa ngokushesha.
Ngaphezu kwalokho, amabhethri e-lithium-ion anezici ezithile zamakhemikhali. Uma eshajwa, ama-ion asuka ku-cathode aye ku-anode nge-electrolyte. Le nqubo ikhiqiza ukushisa, ikakhulukazi lapho ibhethri lisesimweni esithile sokushaja (i-SoC) noma ezimweni zemvelo ezishisayo. Uma izinga lokushisa liphezulu kakhulu, ibhethri libhekana nokucindezeleka, ukusheshisa ukwehla kwamandla, ukunciphisa ukusebenza, futhi, ezimweni ezimbi kakhulu, okungase kube yingozi yokuphepha.
Ukutholwa Kwezinga Lokushisa Elizivumelanisa Nezimo: Kuhluke Kanjani Ekuvikelweni Kwezinga Lokushisa Elivamile?
Amanye amadivayisi abe nokuvikelwa kwezinga lokushisa isikhathi eside—isibonelo, ukuyeka ukushaja lapho izinga lokushisa liphezulu kakhulu. Kodwa-ke, ukutholwa kwezinga lokushisa eliguquguqukayo kuyaqhubeka. Uhlelo alugcini nje "luvala" lapho kufinyelelwa imikhawulo eyeqile, kodwa lulungisa ngokuguquguqukayo iphrofayili yokushaja ngokusekelwe ezindleleni zokushisa, isimo sebhethri, kanye nendawo ezungezile.
Ekuvikelweni okuvamile, amadivayisi ngokuvamile asebenzisa imingcele eqondile: isibonelo, ngaphansi kuka-45°C, ukushaja okusheshayo kuvunyelwe, lapho kunciphisa khona ijubane noma kuyeke. Ngakolunye uhlangothi, izinhlelo ezizivumelanisa nezimo zisebenzisa i-logic yokulawula eqondile: idivayisi ingase inciphise ugesi kancane lapho izinga lokushisa liqala ukukhuphuka ngokushesha, iwukhuphule futhi lapho izinga lokushisa lizinza, noma ishintshe amasu kusukela ekukhuphuleni ugesi kuya ekukhuphuleni ugesi (noma okuphambene nalokho) ngokusekelwe ekusebenzeni kahle kwesekethe kanye nokushisa kwangempela.
Izingxenye Eziyinhloko Zohlelo Lokuthola Izinga Lokushisa Elizivumelanisa Nezimo
Lobu buchwepheshe ngokuvamile buhlanganisa izingxenye eziningana ezibalulekile:
1. Izinzwa zokushisa (izinzwa zokushisa)
Izinzwa zingabekwa eduze kwebhethri, kubhodi lomama, eduze kwe-IC yokushaja, noma ngisho nasesixhumini se-USB-C esivame ukushisa. Amanye amadivayisi asebenzisa izinzwa eziningi ukudala "imephu yokushisa" yangaphakathi.
2. I-BMS (Uhlelo Lokuphatha Ibhethri)
I-BMS “ubuchopho” obulawula ukushaja kwebhethri: ifunda izinga lokushisa, i-voltage yeseli, ugesi, futhi ibala i-SoC. Ezinhlelweni eziguquguqukayo, i-BMS isebenzisa ama-algorithms ukuze inqume imikhawulo ephephile nefanele.
3. Ukushaja i-IC kanye nokuphathwa kwendlela yamandla
Ama-IC okushaja anamuhla asekela ukulawulwa kwamanje/i-voltage okunembile, futhi angaxhumana ne-adaptha ngephrothokholi ethile (isb. Ukulethwa Kwamandla e-USB, Ukushaja Okusheshayo, noma iphrothokholi eyimfihlo).
4. Ama-adaptha namakhebula asekela ukuxhumana
Ukushaja okusheshayo kwesimanje kuvame ukudinga "ukuxoxisana" phakathi kwedivayisi ne-adaptha. Lapho izinga lokushisa likhuphuka, idivayisi ingacela ukuthi i-adaptha inciphise amandla noma ishintshe imodi yokushaja.
Indlela Esebenza Ngayo: Ilungisa Amandla Ngesikhathi Sangempela
Ukushaja okusheshayo ngokutholwa kokushisa okuguquguqukayo kusebenza njengomshayeli ohlakaniphile. Uma umgwaqo ucacile, imoto ingasheshisa. Uma umgwaqo ushelela noma umatasa, ijubane liyancishiswa—hhayi ukuma ngokuphelele, kodwa lilungiswa ukuze kuvikelwe ukuphepha nokusebenza kahle.
Ngokuvamile, inqubo inje:
– Isigaba sokuqala (i-SoC ephansi): idivayisi ivame ukuvumela amandla aphezulu ngoba ibhethri "lisalambile" futhi yamukela kangcono amaza aphezulu.
– Ukuqapha izinga lokushisa: inzwa ifunda izinga lokushisa njalo ngemva kwama-millisecond ambalwa kuya kumasekhondi ambalwa.
– Ukuhlaziywa kwethrendi: hhayi nje izinga lokushisa lamanje, kodwa futhi nezinga lokwehla kwezinga lokushisa. Uma izinga lokushisa likhuphuka ngokushesha kakhulu, uhlelo lunciphisa ngokushesha amandla kagesi.
– Ukulungiswa kwephrofayili: Ukushaja kulawulwa ngezinyathelo eziningana (ukwehla/ukunyuka). Idivayisi ilinganisela imigomo yokuba esheshayo, ephephile, kanye nokugcina impilo yebhethri.
– Isigaba sokugcina (sisondela ku-100%): Ukushaja ngokwemvelo kuyahamba kancane. Yilapho uhlelo luba nomuzwa omkhulu wokushisa kanye ne-voltage, njengoba ibhethri lisengozini enkulu yokucindezeleka kuma-SoC aphezulu.
Ngale ndlela, idivayisi akudingeki ilinde izinga lokushisa lidlule umkhawulo obalulekile ngaphambi kokusabela. Ngenxa yalokho, abasebenzisi basathola ukushaja okusheshayo, kodwa izinzile futhi iphephile.
Izinzuzo Eziqondile Zabasebenzisi
Ubuchwepheshe bokushisa obuzivumelanisa nezimo bunomthelela wangempela, okuhlanganisa:
– Ukuphepha kukhulisiwe
Kunciphisa ingozi yokushisa ngokweqile kwebhethri nesixhumi, ikakhulukazi ngesikhathi sokusetshenziswa kakhulu (isb. ukudlala imidlalo ngenkathi ushaja).
– Impilo yebhethri ende
Ukushisa okuphezulu kuyisitha samabhethri e-lithium-ion. Ukulawula okuzivumelanisa nezimo kusiza ukunciphisa ukuchayeka ekushiseni okweqile, okuholela ekuwohlokeni komthamo kancane kancane.
- Ukusebenza kokushaja okuhambisanayo
Ukushaja akuzizwa zikhuphuka kakhulu noma kume ngokuzumayo. Uhlelo luzivumelanisa kahle ukuze lugcine ukusebenza kahle.
- Induduzo ezimweni ezahlukene
Emakamelweni ashisayo, ngaphakathi emotweni, noma lapho idivayisi ivalwe ngebhokisi elijiyile, uhlelo lungalungisa imikhawulo yokuphepha ngokuzenzakalelayo.
Izinselele kanye nokulinganiselwa
Nakuba iyinkimbinkimbi, lolu hlelo lunemikhawulo eminingana. Okokuqala, izinzwa nama-algorithms awakwazi ukushintsha imithetho yefiziksi: uma indawo ishisa kakhulu noma ingangenisi umoya kahle, amandla okushaja azoncipha ngokungenakugwenywa. Okwesibili, ikhwalithi yekhebula ne-adaptha ibalulekile. Izintambo ezimelana kakhulu zingabangela ukushisa ukuthi kuqongelelane ezixhumini. Okwesithathu, abanye abakhiqizi basebenzisa izinqubo zokushaja okusheshayo ezizimele, okusho ukuthi ukusebenza kahle kutholakala kuphela ngama-adaptha athile.
Ngaphezu kwalokho, kunezindlela zokulungisa ukwakheka: ukwengeza izinzwa, izindlela zokushisa, noma izinhlelo zokupholisa ezingasebenzi kuzokwandisa izindleko kanye nobunzima. Kodwa-ke, izitayela zemboni zibonisa ukuthi lezi zindlela zokulungisa zibhekwa njengezifanelekile njengoba izidingo zabasebenzisi zokushaja okusheshayo ziqhubeka nokukhula.
Ikusasa: Lihlakaniphile Futhi “Liyimfihlo” Kakhulu
Esikhathini esizayo, ukutholwa kwezinga lokushisa eliguquguqukayo kuzohlanganiswa kakhulu nobuhlakani bokwenziwa kanye nedatha yokuziphatha komsebenzisi. Isibonelo, amadivayisi angafunda ukuthi abasebenzisi bavame ukukhipha nini ishaja bese belungisa ukushaja ukuze kufinyelele ku-100% ngesikhathi ngaphandle kokushisa ibhethri ngobusuku obubodwa. Inhlanganisela yokushaja okuguquguqukayo, ukwenza ngcono impilo yebhethri, kanye nokutholwa kwezinga lokushisa ngesikhathi sangempela kuzoba indinganiso entsha.
Ngasohlangothini lwehadiwe, ubuchwepheshe obufana namabhethri anamaseli amabili, amaphampu okushaja, kanye nezakhiwo zokushaja ezidlulisela ukushisa kusuka kudivayisi kuya ku-adaptha kuzosiza ekunciphiseni ukushisa kwangaphakathi. Uma kuhambisana nezinto zokushisa ezithuthukisiwe kanye nemiklamo yokuxhuma esebenza kahle, ukushaja okusheshayo kungaqhubeka nokuthuthuka ngaphandle kokubeka engcupheni ukuphepha.
Isiphetho
Ukushaja okusheshayo akukhona nje kuphela "i-wattage ephezulu." Ukuze ukushaja okusheshayo kube nenzuzo yangempela, kumele kuphephe, kuzinzile, futhi kuhlale isikhathi eside ebhethrini. Ubuchwepheshe bokushaja okusheshayo obunokutholwa kokushisa okuguquguqukayo buyisisombululo esibalulekile: buqapha izinga lokushisa ngesikhathi sangempela, bubikezela ukwakheka kokushisa, futhi bulungisa ngokuhlakanipha amandla okushaja. Umphumela uwukuhlangenwe nakho kokushaja okusheshayo kodwa okulawulwayo—okufanelekile ezindleleni zokuphila zesimanje, ohambweni, ngenkathi futhi kuqinisekisa ukuthi idivayisi ihlala isikhathi eside futhi iphephile.
Uma ungathanda, ngingakha inguqulo yobuchwepheshe yalesi sihloko (isb. ukuxoxa ngama-algorithm okulawula, ama-SoC curve, kanye nesibonelo sokusetshenziswa kwe-USB-PD PPS) noma inguqulo evamile enobungane nebhulogi enolimi olulula.
