Ubuchwepheshe Beshaja Enesici Sokushaja Esivumelana Nezimo
Ukuthuthukiswa kobuchwepheshe bokushaja kwamadivayisi kagesi—ikakhulukazi ama-smartphone, ama-laptop, amaphilisi, kanye nezinto ezigqokwayo—kuye kwashesha kakhulu eminyakeni yamuva. Nakuba ukugxila okuyinhloko kwakuwukuthi “ibhethri lingashajwa ngokushesha kangakanani,” ukunaka manje sekushintshele endabeni ebaluleke kakhulu: indlela yokushaja ngokuphepha, ngempumelelo, nangendlela egcina impilo yebhethri. Yilapho ubuchwepheshe bokushaja obunezici zokushaja eziguquguqukayo budlala khona indima ebalulekile. Lesi sici sinikeza impendulo yenkinga yakudala: abasebenzisi bafuna ukushaja okusheshayo, kodwa ukushaja okusheshayo okungalawulwa kungasheshisa ukuwohloka kwebhethri.
Kuyini Ukushaja Okuguquguqukayo?
Ukushaja okuguquguqukayo ubuchwepheshe bokushaja obulungisa iphethini yamanje, i-voltage, kanye nokushaja ngokusekelwe ezimweni zedivayisi kanye nemikhuba yomsebenzisi. Kalula nje, ishaja kanye nedivayisi "ziyaxhumana" ukuze kunqunywe isu lokushaja elifanele kakhulu. Leli su alisho ukuthi likhulisa isivinini, kodwa kunalokho lifuna ibhalansi phakathi kwesivinini, izinga lokushisa, ukuphepha, kanye nempilo yebhethri yesikhathi eside.
Empeleni, ukushaja okuguquguqukayo kungathatha izindlela eziningana: ukunciphisa amandla njengoba izinga lokushisa likhuphuka, ukugcina ukushaja okuhamba kancane ngephesenti elithile, noma ukulibazisa ukushaja kuze kube seduze nesikhathi esihlosiwe somsebenzisi sokusebenzisa. Isibonelo, uma ushaja ubusuku bonke, ifoni ingabamba ibhethri ku-80% amahora ambalwa, bese ilishaja ngokugcwele ekuseni ukuvimbela ibhethri ukuthi lihlale "ligcwele" isikhathi eside kakhulu (okungasheshisa ukuwohloka).
Kungani Impilo Yebhethri Ithinteka Yiphethini Yokushaja?
Amadivayisi amaningi esimanje asebenzisa amabhethri e-lithium-ion noma e-lithium-polymer. Lezi zinhlobo zamabhethri zizwela izici eziningana ezibalulekile:
1. Ukushisa (izinga lokushisa eliphezulu)
Ukushaja okusheshayo kudala ukushisa, futhi ukushisa kuyisitha esiyinhloko sempilo yebhethri. Uma ibhethri lisebenza kaningi emazingeni okushisa aphezulu, amandla alo ancipha ngokushesha.
2. I-voltage ephezulu uma isondela ku-100%
Uma ibhethri liphezulu, liba namandla aphezulu. Ukushiya ibhethri lise-100% isikhathi eside kungandisa ukucindezeleka kwamakhemikhali kumaseli ebhethri.
3. Amandla kagesi amakhulu (ukushaja okusheshayo okunamandla)
Amaza aphezulu asheshisa ukushaja, kodwa futhi angangeza ukucindezeleka nokushisa ebhethrini uma engaphathwa kahle.
4. Imikhuba yokusebenzisa
Imikhuba yabasebenzisi ihlobene nesikhathi sokushaja, ukuthi idivayisi idinga ukulungela nini ukusetshenziswa, nokuthi kwenziwa kangaki ukwengeza.
Ukushaja okuzivumelanisa nezimo kulapha ukuze kuncishiswe umthelela walezi zici ngokusebenzisa izilungiselelo ezihlakaniphile.
Indlela Ukushaja Okuzivumelanisa Nezimo Okusebenza Ngayo Ezweni Langempela
Ubuchwepheshe bokushaja obuhambisana nezimo budinga ukusebenzisana kwezinto ezintathu: ishaja, ikhebula, kanye nedivayisi (kanye nohlelo lokuphatha ibhethri/i-BMS). Nasi isifinyezo sendlela esebenza ngayo:
1. Ukuxoxisana Ngamandla
Ngezindinganiso ezithile ezifana ne-USB Power Delivery (USB PD), amadivayisi angacela amaphrofayili athile wamandla—isibonelo, i-5V/3A, i-9V/2A, noma i-20V/3A. Idivayisi “ayiphoqelekile” ukwamukela amandla aphezulu; ikhetha ngokusekelwe ezidingweni zayo.
2. Ukuqapha izinga lokushisa kanye nesimo sebhethri
Izinzwa zangaphakathi ziqapha izinga lokushisa lebhethri, izinga lokushisa lesekethe yokushaja, kanye nezimo zamanje zokungena. Uma izinga lokushisa likhuphuka ngaphezu komkhawulo ophephile, uhlelo lunciphisa amandla okushaja.
3. I-algorithm yokugcwalisa kancane kancane
Ngokuvamile, ukushaja ibhethri le-lithium kwenzeka ngezigaba ezimbili eziyinhloko:
– I-Constant Current (CC): i-constant current yokushaja okusheshayo ngamaphesenti aphansi naphakathi.
– I-Voltage Engaguquki (CV): i-voltage engaguquki isondela ekugcwaleni, ugesi wehla kancane kancane.
Ukushaja okuguquguqukayo kungashintsha ulaka lwesigaba se-CC kanye nendlela esishintshela ngayo ku-CV, okuhlanganisa "ukusetha ikhefu" cishe ngo-80-90% ukuze kuncishiswe ukucindezeleka kwebhethri.
4. Ukushaja Okusekelwe Ekuziphatheni
Kwamanye amadivayisi, uhlelo lufunda izikhathi zokulala nezokuvuka zomsebenzisi. Uma idivayisi ilinganisela ukuthi ngeke uvuke kuze kube ngu-6:00 AM, ishaja cishe ngo-100% kuleso sikhathi, kunokuba ishaje ngokugcwele phakathi kwamabili.
Izinzuzo Eziyinhloko Zeshaja Enokushaja Okuzivumelanisa Nezimo
1. Yehlisa ijubane lokuwohloka kwebhethri
Ngokunciphisa ukuvezwa ekushiseni nokugwema ukuvezwa isikhathi eside ku-voltage ephezulu (100%), impilo yebhethri ingagcinwa kangcono. Ngokuhamba kwesikhathi, lokhu kungasho umthamo webhethri ozinzile uma kuqhathaniswa nephethini yokushaja "eqhubekayo esheshayo".
2. Ukushaja Okuphephile
Izici ezizivumelanisa nezimo zivame ukuhambisana nezinhlelo zokuvikela: ukuvikelwa kwamandla kagesi angaphezulu, ukuvikelwa kwamandla kagesi angaphezulu, ukuvikelwa kokushisa okungaphezulu, kanye nokulawula ukuxhumana kwamandla. Ukushaja okuphendulayo ekushiseni kusiza ukuvimbela izingozi ezifana nokubaleka kokushisa ngaphansi kwezimo ezimbi kakhulu.
3. Ukusebenza Kahle Kahle Kwamandla
Ukushaja okunamandla ngokweqile kungadala ukushisa, okuholela ekugcineni emandleni alahlekile. Ngokulinganisela ukushaja, amadivayisi anganciphisa imfucuza yamandla ngendlela yokushisa.
4. Ulwazi Lomsebenzisi Olukhululekile Kakhulu
Abasebenzisi akudingeki baqaphe ibhethri njalo noma bakhiphe ishaja ngamaphesenti athile. Uhlelo lunquma ngokuzenzakalelayo ukuthi kufanele lushaje nini ngokushesha, kancane, nokuthi kufanele lubambezele nini ukushaja.
Umehluko Phakathi Kokushaja Okuzivumelanisa Nezimo Nokushaja Okusheshayo Okuvamile
Abantu abaningi badidanisa ukushaja okuguqukayo nokushaja okusheshayo, kodwa lokhu kokubili akufani. Ukushaja okusheshayo kugxile ekusheshiseni ukushaja, kuyilapho ukushaja okuguqukayo kugxile ekwenzeni ngcono.
– Ukushaja okusheshayo okuvamile: kuvame ukuxosha amandla aphezulu isikhathi eside ngangokunokwenzeka, futhi kunciphisa ijubane kuphela njengoba kusondela ukushaja okugcwele.
– Ukushaja okuzivumelanisa nezimo: kulungisa amandla okushaja ngokusekelwe kumongo—kungashesha ekuqaleni, bese kwehliswa ijubane kusenesikhathi, noma kubambezele ukushaja okuphelele kuze kube yisikhathi esithile.
Noma kunjalo, zombili zingasebenza ngesikhathi esisodwa: ukushaja okusheshayo kusatholakala, kodwa kulawulwa ngendlela efanele ukuze kungalimazi ibhethri.
Amazinga Asekelayo kanye Nezinhlelo Zemvelo
Ezinye zezindinganiso nobuchwepheshe obuvame ukuhlotshaniswa nokushaja okuguquguqukayo zifaka:
– Ukulethwa Kwamandla e-USB (i-USB PD): indinganiso ebanzi evumela ukuxoxisana kwamaphrofayili ahlukene wamandla kanye ne-voltage/amanje.
– Ukunikezwa Kwamandla Okuhlela (i-PPS): ingxenye ye-USB PD evumela ukulungiswa kwamandla kagesi okuguquguqukayo nokushelelayo, okusiza ukusebenza kahle kanye nokuphathwa kokushisa.
– Ubuchwepheshe bobunikazi: Abanye abakhiqizi banezinqubo zabo, ngokuvamile ukuze bathole amandla aphezulu. Kodwa-ke, izimiso zokuzivumelanisa nezimo zingasetshenziswa ngokulawula izinga lokushisa, amaphrofayili okushaja, kanye nama-algorithm ebhethri.
Ezimweni eziningi, amadivayisi esimanje anezinhlelo zokuphatha amabhethri eziyinkimbinkimbi, ngakho-ke noma ngabe ishaja "ingahlakaniphile," idivayisi isakwazi ukuphatha amandla angenayo. Kodwa-ke, amashaja asekela amazinga esimanje (njenge-PD/PPS) anikeza ukulawula okwengeziwe.
Ingabe Wonke Amashaja “Ayazivumelanisa Nezimo” Ngokuzenzakalelayo?
Akunjalo ngaso sonke isikhathi. Kunezinhlangothi ezimbili ezivumelana nezimo: uhlangothi lweshaja kanye nohlangothi lwedivayisi. Amafoni anamuhla ngokuvamile anekhono lokulawula ukushaja, kodwa ishaja enhle izokwenza lokhu:
– Isekela izinqubo zokuxoxisana ngamandla (isb. i-USB PD).
– Izinzile ekunikezeni amandla kumaphrofayili ahlukahlukene.
– Inezinga lokushisa elifanele kanye nokuvikelwa kwamandla kagesi.
– Ukusebenzisa izingxenye zekhwalithi (i-IC yokulawula, ama-capacitor, ama-transformer/ama-inductor).
Uma ishaja ingahambisani noma isezingeni eliphansi, ukushaja kungaba kushisa kakhulu, kuhambe kancane, noma kungazinzile, ekugcineni kunciphisa izinzuzo zokushaja okuhambisanayo.
Amathiphu Okukhulisa Izinzuzo Zokushaja Okuzivumelanisa Nezimo
1. Sebenzisa ishaja nekhebula elihlangabezana nezindinganiso.
Izintambo ezimbi zingabangela ukwehla kwamandla kagesi futhi zandise ukushisa kusixhumi.
2. Gwema ukushaja ezindaweni ezishisayo
Isibonelo, ngaphansi komcamelo, kumatilasi, noma kudeshibhodi yemoto evezwe elangeni.
3. Nika amandla isici sokwenza ngcono ukushaja kuzilungiselelo
Amadivayisi amaningi anikeza izinketho ezifana nokuthi “Ukushaja Okulungiselelwe”, “Ibhethri Elizivumelanisa Nezimo”, noma “Impilo Yebhethri”.
4. Asikho isidingo sokuhlala ucabanga ngo-100% ngaso sonke isikhathi
Uma kungadingeki, ukuzijwayeza ukushaja kufike ku-80–90% kungasiza impilo yebhethri—futhi ukushaja okuzivumelanisa nezimo kuvame ukuklanywa ukuze kube lula lo mkhuba ngokuzenzakalelayo.
Isiphetho
Ubuchwepheshe bokushaja obuhambisana nezimo buyinguquko ebalulekile ezweni lokushaja. Abubeki phambili isivinini kuphela kodwa nempilo yebhethri, ukuphepha, kanye nokusebenziseka kalula komsebenzisi. Ngokusebenzisa ukuxoxisana ngamandla, ukuqapha izinga lokushisa, kanye nama-algorithms okushaja ahlakaniphile (kufaka phakathi amaphethini asekelwe emikhubeni), ukushaja okuvumelana nezimo kusiza amadivayisi ukuthi ahlale isikhathi eside futhi asebenze ngokuqhubekayo.
Esikhathini lapho amabhethri eyinhliziyo cishe yawo wonke amadivayisi aphathekayo, ukushaja okuhambisanayo akuseyona nje into eyengeziwe. Kuyitshalomali yesikhathi eside egcina ukusebenza kwedivayisi, kunciphisa izindleko zokufaka ibhethri, futhi kunikeza ulwazi olubushelelezi lwansuku zonke. Lapho ukhetha ishaja entsha, ungacabangi nje kuphela ngamandla kagesi, kodwa futhi nezindinganiso ezisekelayo kanye nobuhlakani bokushaja obunikezayo—ngoba ukushaja okuhle akusheshi nje kuphela; kunembile.
