Ubuchwepheshe Bokushaja Okuhlakaniphile Ngokutholwa Kwedivayisi Okuzenzakalelayo
Endleleni yokuphila yeselula yanamuhla, isidingo sokushaja okusheshayo, okuphephile, nokusebenza kahle siya ngokuya siba yinto ebaluleke kakhulu. Cishe wonke umuntu uphethe amadivayisi angaphezu kweyodwa: ifoni ephathekayo, ithebhulethi, iwashi elihlakaniphile, ama-earbud angenantambo, noma ngisho ne-laptop. Inselele ukuthi idivayisi ngayinye inezidingo zamandla ezihlukile. Ukushaja ngaphandle kokulawula okufanele kungabangela ukushaja okuhamba kancane, amazinga okushisa aphezulu, impilo yebhethri encishisiwe, ngisho nomonakalo wedivayisi. Yilapho ubuchwepheshe bokushaja obuhlakaniphile obunokutholwa kwedivayisi okuzenzakalelayo bungena khona, buhlanganisa ubuhlakani ku-adaptha, ikhebula, noma imbobo yokushaja ukuze "kuqashelwe" idivayisi futhi kulungiswe amapharamitha okushaja ngendlela efanele.
Kuyini Ukushaja Okuhlakaniphile?
Ukushaja okuhlakaniphile kuyindlela yokushaja edlula nje ukuletha ugesi ukuze kuphathwe inqubo yokushaja ngokuqapha nokulawula okuhlakaniphile. Lobu buchwepheshe bungatholakala kumashaja odonga, amabhange kagesi, amachweba e-USB ezimoto, iziteshi zokushaja ezinamachweba amaningi, ngisho nezinhlelo zokushaja ezihlanganisiwe kuma-laptops nama-monitor. Igama elithi "Smart" lapha lisho ukuthi ishaja ingalungisa i-voltage (volts), i-current (amperes), kanye namasu okushaja ngezinye izikhathi ngokusekelwe kulwazi olutholwe kudivayisi.
Ukushaja okuhlakaniphile kwesimanje kuvame ukusebenza ngokubambisana nezindinganiso ezifana ne-USB Power Delivery (USB-PD), i-Qualcomm Quick Charge, noma ezinye izinqubo zokushaja okusheshayo. Kodwa-ke, okwenza kube yinto ebaluleke nakakhulu isici sayo sokuthola idivayisi ngokuzenzakalelayo—ikhono lokubona uhlobo lwedivayisi, izidingo, kanye namakhono ngaphambi kokunquma ukuthi kufanele inikeze amandla angakanani.
Kungani Kudingeka Ukutholwa Kwedivayisi Okuzenzakalelayo?
Ezinsukwini zokuqala ze-USB, amashaja amaningi ayenikeza kuphela amandla okukhipha aqinile, njenge-5V 1A noma i-5V 2A. Lokhu kwakwanele kumadivayisi alula, kodwa akufanelekile ohlelweni lwanamuhla lwedivayisi. Isibonelo:
– Amanye ama-smartphone asekela ukushaja okusheshayo okungu-18W, 25W, 45W, noma ngisho nangaphezulu.
– Amaphilisi angadinga amandla aphezulu ukuze ahlale eshaja ngesikhathi esetshenziswa.
– Ama-laptop nge-USB-C angadinga ama-45W, 65W, 100W, kuze kufike ku-240W (i-USB PD Extended Power Range).
– Amadivayisi amancane afana nama-earbud empeleni adinga ugesi ophansi ukuze aphephe.
Ngaphandle kokuthola ngokuzenzakalelayo, ishaja ingase "inikeze" amandla. Ngokuthola ngokuzenzakalelayo, ishaja isebenza njengesilawuli sethrafikhi: inikeza amandla anele, hhayi amaningi kakhulu, futhi ngokuya ngamakhono edivayisi kanye nekhebula elisetshenziswayo.
Indlela Ukutholwa Kwedivayisi Okuzenzakalelayo Okusebenza Ngayo
Ukutholwa kwamadivayisi ngokuzenzakalelayo kuvame ukwenzeka ngezinyathelo eziningana eziyinhloko:
1. Ukuxhawulana (ingxoxo yokuqala)
Uma idivayisi ixhunyiwe, ishaja kanye nedivayisi kuqala ukuxhumana kokuqala. Ku-USB-C, lokhu kungenziwa nge-CC (Isiteshi Sokucushwa). Yilapho idivayisi "itshela" idivayisi ngezidingo zayo zamandla kanye nezindinganiso ezisekelwayo. Ishaja ibe isinikeza iphrofayili yamandla ethile.
2. Thola amaphrothokholi ahambisanayo
Uma idivayisi isekela i-USB-PD, inqubo yokuxoxisana izolandela i-PD. Ngaphandle kwalokho, ishaja ingashintshela kwimodi ye-5V ezenzakalelayo noma isebenzise enye iphrothokholi, njenge-QC. Amashaja ephrothokholi eminingi ngokuvamile anesilawuli esikwazi ukubona amaphethini esignali noma izidingo zamandla.
3. Ukulungiswa kwe-voltage kanye nokwamanje

4. Ukuqapha izinga lokushisa kanye nezimo zikagesi
Izinhlelo eziningi zokushaja ezihlakaniphile ziqapha izinga lokushisa le-adaptha, i-port, ngisho nebhethri (ngedatha evela kudivayisi). Uma izinga lokushisa likhuphuka, amandla angancishiswa okwesikhashana.
5. Ukuthuthukisa isigaba sokushaja ibhethri
Amabhethri e-lithium avame ukushajwa kusetshenziswa indlela ye-CC-CV (Constant Current – Constant Voltage): ugesi ophezulu ekuqaleni, bese kuba ukwehla njengoba ugesi usondela kumthamo ogcwele. Ukushaja okuhlakaniphile kuphatha lesi sigaba ngokunembile, kunciphisa ukucindezeleka ebhethrini.
Izingxenye Eziyinhloko Ekushajeni Okuhlakaniphile
Lobu buchwepheshe abuzimele bodwa; kunezinto eziningana ezibalulekile ezisebenzisanayo:
– I-IC Yokuphathwa Kwamandla (i-PMIC)
I-chip ephatha ukucutshungulwa kwamandla, ukuxoxisana, ukuvikelwa, kanye nokusatshalaliswa kwamandla.
- Izinqubo zokushaja (i-USB-PD, i-QC, i-AFC, i-SCP, njll.)
Lolu "ulimi" lokuxhumana phakathi kweshaja nedivayisi.
– Ikhebula elisezingeni eliphezulu kanye ne-e-marker (kweminye i-USB-C)
Ukuze kusetshenziswe amandla amaningi, izintambo ze-USB-C zivame ukudinga i-chip ye-e-marker ekhombisa amandla ekhebula (isb., ukuthi lisekela i-5A noma cha). Ngaphandle kwekhebula elifanele, ishaja izonciphisa amandla ngezizathu zokuphepha.
- Inzwa yokushisa kanye nokuvikelwa
Kubandakanya i-over-voltage, i-over-current, ukuvikelwa kwe-short circuit, kanye nokutholakala kwezinto zangaphandle ekushajeni okungenantambo.
Izinzuzo Zokushaja Okuhlakaniphile Ngokuthola Okuzenzakalelayo
1. Kuphephile
