Kungani ukushaja kuhamba kancane esigabeni sokugcina?

Kungani ukushaja kuhamba kancane esigabeni sokugcina?

Bonke abasebenzisi be-smartphone bayaqaphela ukuthi ukushajwa kwebhethri kuba kancane uma ibhethri selizogcwala. Lokhu kungase kuphakamise imibuzo yabasebenzisi.

Imvamisa, i-smartphone ingashaja ngokushesha okukhulu, isuka ku-0% iye ku-80%. Mayelana nephesenti elisele lokuqedela ukuthunyelwa, lidinga isikhathi eside.

Isizathu singenxa yendlela yokusebenza kwamabhethri e-lithium-ion ngokujwayelekile. Lawa amabhethri asetshenziswa kuma-smartphone, amakhompyutha aphathwayo, ngisho nasezimotweni zikagesi.

Ibhethri lishaja kancane

Amabhethri e-lithium-ion ashajwa ngezigaba ezintathu ezilandelanayo. Lezi zigaba zenzelwe ikakhulukazi ukuvikela amabhethri kunoma yiziphi izingozi ngakolunye uhlangothi, futhi ngakolunye uhlangothi ukulondoloza ubude bawo bokuphila.

Isigaba sokuqala saziwa ngokuthi yi-pre- charge, noma i-Pre-Charge. Ngalesi sigaba, i-current 3 volts ikhishwa ebhethri. Lo mthamo ophansi uvuselela ibhethri futhi uyilungiselele ukuqedela inqubo yokushaja. Lokhu kungenxa yokuthi ibhethri lifinyelela esimweni sokungalali uma lishiywe lingashajiwe isikhathi eside.

Le ndlela iphinde isize ukuvuselela isivikelo sebhethri, okungenye yezingxenye zayo eziyinhloko. Kodwa inqubo yokushaja ngaphambilini incike kuphela ku-10% womthamo wokushaja osekelwa yikho kokubili ifoni neshaja. Lokhu kuchaza ukuthi kungani udinga ukushiya ifoni ixhumeke esikrinini imizuzu embalwa ngaphambi kokuthi uyivule uma ishaje engu-0%.

Izigaba zokushaja

Lapho lesi sigaba sesiphelile, isigaba sesibili siyaqala. Iyona eqala ngokunembile lapho ibhethri ifika esigabeni sama-volt angu-3 ngendlela ezinzile. Isigaba sesibili saziwa ngeConstant Current. Ucingo bese luqala ukushesha ukushaja kancane kancane.

Kuleli qophelo, imodi yokushaja okusheshayo yefoni iyasebenza, uma ikhona. Lesi sigaba siyaqhubeka nokushaja ifoni ngokushesha ngangokunokwenzeka ize ifinyelele ku-80%.

Le ndlela iphinde isize ukuvuselela isivikelo sebhethri, okungenye yezingxenye zayo eziyinhloko. Kodwa inqubo yokushaja ngaphambilini incike kuphela ku-10% womthamo wokushaja osekelwa yikho kokubili ifoni neshaja. Lokhu kuchaza ukuthi kungani udinga ukushiya ifoni ixhumeke esikrinini imizuzu embalwa ngaphambi kokuthi uyivule uma ishaje engu-0%.

Ngemva kwalokho, ukushaja ibhethri kungena esigabeni sayo sesithathu. Lesi sigaba saziwa nangokuthi i-voltage engaguquki. Kulesi sigaba, ifoni ithola i-voltage engaguquki, yingakho isiteji sinenkinga yokunensa. Nokho, inhloso yalobu buchwepheshe ukugcina ifoni ingashaji kakhulu, nokuvikela ibhethri lilonke.

Kuyaziwa futhi ukuthi ukushaja i-smartphone kukalwa ngama-watts. Kungumkhiqizo we-voltage ne-current.

Kulesi sigaba, amandla kagesi aqhubeka ehla ngokuqhubekayo kuze kube yilapho ibhethri ishajwa ngokugcwele, futhi ezigabeni zokugcina, okwamanje isezingeni eliphansi kakhulu, ngenxa yomphumela wokuzinza kwe-voltage.

Ize ishiye ifoni ixhumeke eshajani okwamanje ithola amandla angu-4 volts kuphela. Ucingo luhlala lugcwele ngo-100% futhi uma lwehla luye ku-99% le voltheji elula iyibuyisela ku-100%.
