Kutheni ukutshaja kucotha kwinqanaba lokugqibela?

Bonke abasebenzisi be-smartphone baqaphela ukuba intlawulo yebhetri iyacotha xa ibhetri isondela ngokupheleleyo. Oku kunokuphakamisa imibuzo yabasebenzisi.

Ngokuqhelekileyo, i-smartphone inokuhlawula ngokukhawuleza, ukusuka kwi-0% ukuya kwi-80%. Ngokuphathelele ipesenti eseleyo ukugqiba ukuthunyelwa, kufuna ixesha elide.

Isizathu sibangelwa yindlela yokusebenza kweebhetri ze-lithium-ion ngokubanzi. Ezi ziibhetri ezisetyenziswa kwii-smartphones, iilaptop, kunye neemoto zombane.

Ibhetri itshaja kancinane

Iibhetri ze-lithium-ion zihlawuliswa kwizigaba ezintathu ezilandelelanayo. Ezi zigaba zenzelwe ukukhusela iibhetri kuzo naziphi na iingozi kwelinye icala, kwaye kwelinye icala ukugcina ixesha labo lokuphila.

Inqanaba lokuqala laziwa njengenqanaba lokuhlawuliswa kwangaphambili, okanye i-Pre-Charge. Ngeli nqanaba, okwangoku i-3 volts ikhutshwa kwibhetri. Lo mthamo usezantsi uhlaziya ibhetri kwaye uyilungiselele ukugqibezela inkqubo yokutshaja. Oku kungenxa yokuba ibhetri ifika kwindawo yokulala xa ishiywe ingatshajwanga ixesha elide.

Le ndlela iphinda incede ukuvuselela ibhetri yokukhusela ibhetri, enye yezona zinto ziphambili. Kodwa inkqubo yokutshaja kwangaphambili ixhomekeke kuphela kwi-10% yomthamo wokutshaja oxhaswa yifowuni kunye netshaja. Oku kuchaza ukuba kutheni kufuneka ushiye ifowuni eqhagamshelwe kwisikrini imizuzu embalwa ngaphambi kokuba uyivule ukuba ine-0%.

Amanqanaba okutshaja

Ekugqityweni kwesi sigaba, isigaba sesibini siqala. Yiyo eqala ngokuchanekileyo xa ibhetri ifikelela kwinqanaba le-3 volt ngendlela ezinzileyo. Inqanaba lesibini laziwa njenge Constant Current. Ifowuni ke iqala ukutshaja ngokukhawuleza kancinci kancinci.

Ngeli xesha, imowudi yokutshaja ngokukhawuleza yefowuni iyasebenza, ukuba ikhona. Eli nqanaba liqhubeka lihlawula ifowuni ngokukhawuleza kangangoko kunokwenzeka ide ifike kwi-80%.

Le ndlela iphinda incede ukuvuselela ibhetri yokukhusela ibhetri, enye yezona zinto ziphambili. Kodwa inkqubo yokutshaja kwangaphambili ixhomekeke kuphela kwi-10% yomthamo wokutshaja oxhaswa yifowuni kunye netshaja.

Emva koko, ukutshaja ibhetri kungena kwinqanaba lesithathu. Eli nqanaba likwabizwa ngokuba yi-voltage eqhubekayo - okanye iivolthi. Kweli nqanaba, ifowuni ifumana i-voltage eqhubekayo, kwaye yiyo loo nto inqanaba libandezeleka kancinci. Nangona kunjalo, injongo yale teknoloji kukugcina ifowuni ingagqithisi, kunye nokukhusela ibhetri ngokubanzi.

Kukwayaziwa ukuba ukutshaja i-smartphone kulinganiswa ngeewatts. Yimveliso yombane kunye nekhoyo ngoku.

Ngeli nqanaba, umbane wombane uqhubeka uhla ngokuqhubekayo de kube ibhetri ihlawuliswe ngokupheleleyo, kwaye kwizigaba zokugqibela, okwangoku kumanqanaba aphantsi kakhulu, ngenxa yesiphumo sokuzinza kombane.

Ide ishiye ifowuni iqhagamshelwe kwitshaja kweli nqanaba ifumana kuphela i-4V yamandla. Ifowuni ihlala i-100% igcwele kwaye xa ihla ukuya kwi-99% le mbane elula iyibuyisela kwi-100%.
