Yara masu hankali na iya lura cewa duka ƙarfin wutar lantarki da kwamfutar tafi-da-gidanka suna da baturin 5000mAh iri ɗaya, amma na ƙarshe ya fi na baya girma.

To abin tambaya anan shine: Dukkansu baturan lithium ne, amma me yasa batura iri daya suka yi nisa? Ya bayyana cewa kodayake duka biyun ne, amma lura da hankali, ƙarfin ƙarfin V da Wh na batura biyu kafin mAh sun bambanta.

Menene bambanci tsakanin mAh da W?

Milliampere hour (milliampere hour) shine naúrar wutar lantarki, kuma Wh shine naúrar makamashi.

Wadannan ra’ayoyi guda biyu sun bambanta, tsarin juyawa shine: Wh=mAh × V(voltage)&Pide;1000.

Musamman, milliampere-hours za a iya fahimta a matsayin jimlar adadin electrons (yawan electrons wucewa ta halin yanzu na 1000 milliampere-hours). Amma don ƙididdige adadin kuzari, dole ne mu lissafta makamashin kowane lantarki.

A ce muna da 1000 milliamperes na electrons, kuma ƙarfin kowane electron shine 2 volts, don haka muna da awa 4 watt. Idan kowane lantarki 1v ne kawai, muna da kuzarin watt-1 kawai.

Babu shakka, man fetur nawa nake so, kamar lita daya; Wh yana nufin nisan da lita daya na man fetur zai iya tafiya. Don lissafin yadda litar mai za ta iya tafiya, dole ne mu fara ƙididdige ƙaura. A wannan yanayin, ƙaura shine V.

Sabili da haka, ƙarfin nau’ikan kayan aiki daban-daban (saboda bambance-bambancen wutar lantarki) yawanci ba a iya aunawa ba. Batir ɗin kwamfutar tafi-da-gidanka sun fi girma da ƙarfi, amma suna yin aiki fiye da batir na hannu a lokaci guda, kuma ba lallai ba ne su daɗe fiye da hanyoyin samar da wutar lantarki.

Me yasa wakilai suke amfani da Wh maimakon mAh a matsayin iyaka?

Mutanen da ke yawan tashi da jirgi na iya sanin cewa Hukumar Kula da Sufurin Jiragen Sama tana da ƙa’idodi masu zuwa kan baturan lithium:

Na’urar lantarki mai šaukuwa tare da ƙarfin baturin lithium wanda bai wuce 100Wh ba yana shiga, kuma ba za a iya ɓoye shi a cikin kaya da aikawa ba. Jimlar ƙarfin baturi na duk kayan lantarki da fasinjoji ke ɗauka ba zai wuce 100Wh ba. Batirin lithium da ya wuce 100Wh amma bai wuce 160Wh yana buƙatar amincewar jirgin sama don aikawa ba. Batura lithium da suka wuce 160Wh ba za a ɗauka ko aikawa ba.

Ba dole ne mu yi tambaya kawai ba, me yasa FAA ba ta amfani da awoyi na milliampere a matsayin ma’auni?

Idan aka yi la’akari da cewa baturin zai iya fashewa, ƙarfin amfani da fashewa yana da alaƙa kai tsaye da girman makamashi (Wh shine sashin makamashi), don haka dole ne a ƙayyade sashin makamashi a matsayin iyaka. Misali, baturin 1000mAh kadan ne, amma idan karfin baturi ya kai 200V, to yana da awanni 200 na makamashi.

Me yasa wayoyin hannu suke amfani da awoyi milliampere maimakon watt-hours don kwatanta batir lithium 18650?

Kwayoyin batirin lithium na wayar hannu suna da mahimmanci, saboda mutane da yawa ba su fahimci manufar watt-hours ba. Wani dalili kuma shine kashi 90% na batirin lithium na wayar hannu batir polymer 3.7V ne. Babu haɗin jerin da layi daya tsakanin batura. Saboda haka, ikon magana kai tsaye ba zai haifar da kurakurai da yawa ba.

Wani 10% ya yi amfani da polymer 3.8 V. Ko da yake akwai bambancin wutar lantarki, akwai kawai bambanci tsakanin 3.7 da 3.8. Don haka, yana da kyau a yi amfani da bayanin mAh na baturi a cikin tallan wayar hannu.

Menene ƙarfin baturi na kwamfyutoci, kyamarori na dijital, da sauransu?

Wutar baturi ya bambanta, don haka an yi musu alama a fili da watt-hours: ƙananan kwamfyutoci masu ƙarfi suna da kewayon wutar lantarki kusan awanni 30-40, kwamfyutocin tsakiyar kewayon suna da ikon kusan awanni 60 watt, kuma babba. -Batura na ƙarshe suna da kewayon iko na 80. -100 watt-hours. Wurin wutar lantarki na kyamarori na dijital shine awa 6 zuwa 15 watt, kuma wayoyin salula yawanci awanni 10 ne.

Ta wannan hanyar, zaku iya amfani da kwamfutar tafi-da-gidanka (awanni 60 watts), wayoyin hannu (awanni 10 watts) da kyamarori na dijital (awanni 30 watts) don tashi kusa da iyaka.
