1. Menene mafi kyawun halin yanzu don batir lithium masu caji?
Dole ne a fara cajin baturan lithium da ruwan zafi na yau da kullun, wato dole ne a sami halin yanzu, kuma ƙarfin baturi da tsarin cajin suna ƙaruwa sannu a hankali, lokacin da ƙarfin baturi ya kai 4.2V, dole ne ya kai 4.1V), don cajin wutar lantarki akai-akai, ba cajin baturin ba. Dole ne ƙarfin lantarki ya kasance yana da tushe na halin yanzu Cikakkun madaidaicin caji na yau da kullun ana yin caji a gefe na sama, kuma tsarin caji yana ci gaba da ragewa. Lokacin da aka saukar da zafin jiki zuwa digiri 0.01 Celsius, ana dakatar da cajin. (C hanya ce ta bayyana ƙarfin baturi bisa ga halin yanzu. Misali, idan ƙarfin baturi ya kasance 1000mAh, 1C shine cajin halin yanzu na 1000mA. Lura cewa wannan mA ne, ba Ah ba. Me yasa tunanin cewa 0.01C ita ce cajin tashar tashar: Wannan shi ne ma’aunin GB na kasa / T18287-2000 shima bita ne.A baya, mun kammala 20mA.

2. Menene mafi kyawun ƙarfin lantarki don batir lithium masu caji?
Matsakaicin ƙarfin ƙarfin baturi na lithium shine 3.7V (3.6V), kuma cajin yanke wutar lantarki shine 4.2V (4.1V, dangane da alamar baturi, kuma ƙirar ta bambanta). Yadda ake bambance 4.1V da 4.2V: Masu cin kasuwa ba za su iya bambanta tsakaninsa ba, kuma ya dogara da ƙayyadaddun samfuran Manufacturer na baturi. Wasu nau’ikan batura gabaɗaya 4.1V da 4.2V, kamar A&TB (Toshiba), masana’antun cikin gida sune 4.2V. Me zai faru idan ka yi cajin baturi 4.1V zuwa 4.2V? Wannan zai ƙara ƙarfin baturi kuma ya sauƙaƙe don amfani. A ɗauka daga 500 zuwa 300. Hakazalika, idan baturin 4.2V ya yi yawa, za a gajarta rayuwarsa. Batura lithium ba su da ƙarfi. Idan baturin yana da allon kariya, za mu iya daidaita shi? A’a, saboda ma’aunin yanke na hukumar kariya shine 4.35V (lafiya, amma bambanci tsakanin 4.4V da 4.5V), don haka kwamitin kariya ya yi hulɗa da tsaka-tsakin mita. Idan batirin yana caji kowane lokaci, zai tsufa da sauri.
3. Menene ƙarfin baturi na Apple iPhone?
Ƙayyadaddun baturi na Apple iPhone suna da ƙananan ƙarfin lantarki na 3.7V, cajin yanke wuta na 4.2V, da ƙarfin baturi na 1400mAh. Ana iya gani daga sama cewa ƙimar caji mafi kyau shine 1C. A halin yanzu da ake buƙata don isa 1400mA yana farawa caji a ƙarfin lantarki na 3.7V.
4. Menene ƙarfin lantarki da halin yanzu na tashar USB da caja?
Usb interface halin yanzu shine 500mA, ƙarfin lantarki shine + 5V. Idan kun juya HWinfo yayin caji, kuna iya ganin wutar lantarki ta waje. An tsara cajar 500mA don iPhone. A taƙaice, lokacin da kebul na caji, ƙarfin lantarki shine +5V kuma na yanzu shine 500mA kawai. Daga amsoshin Tambaya ta 1 da Tambaya ta 2, mun san cewa wannan hanyar tana ƙara ƙarfin baturi, wanda ke da sanyi don amfani, amma yana rage rayuwar baturi. Lokacin amfani da caja don yin caji, muna iya tambaya, shin ba ku ce mafi kyawun gudun shine 1C ba? Daidai ne a yi tunanin cewa ya kamata a caje iPhone da ƙarfin halin yanzu na 1400mA, i, amma ƙasar kuma tana da ƙa’idodi. Ƙananan cajin da aka ƙayyade ta gb shine 0.2C. (Tsarin cajin da aka tsara), kuma ɗauki batirin ƙarfin ƙarfin 1400mAh na iPhone a matsayin misali, wanda shine 280mA. A ka’idar, ƙarami baturi, mafi fa’ida. Amma ba za ku iya jira kwanaki uku don cajin baturi ba. (Irin mAh = halin yanzu mA x lokacin h) Don haka Apple ya zaɓi 0.7C, yawancin batura suna tsakanin 0.5C da 0.8C, zaku iya zaɓar 5! Babu shakka, wasu mutane suna amfani da USB don caji, wanda ke jin tsawon rayuwa, amma wannan baturi ne na musamman Darajar rayuwa
