Litiy ionli batareyalar-tez zaryadlash xususiyatlari qanday?
2015 yilning ikkinchi yarmidagi modellar odatda tez zaryadlash texnologiyasini qo'llaydi. Umuman olganda, men 10 Vt (ya'ni 5V2A) dan ortiq zaryadlashni tez zaryadlash deb hisoblayman.
Birinchidan, mobil telefonlarni zaryadlash evolyutsiyasiga qisqacha qarash:
Avvaliga telefonning batareyasi unchalik katta emas edi. Ayni paytda standart USB interfeysi 5V0.5a zaryadlash ehtiyojlarini qondira oladi; ammo aqlli telefonlar paydo bo'lgandan so'ng, ishlashga bo'lgan katta tashnalik tufayli, quvvat sarfi oshadi va 0.5a talabni qondira olmaydi; bu kengaytirilgan USB zaryadlovchi identifikatsiya standartini bildiradi: BC1 .2. Zaryadlash oqimi 5V1,5a ga yetishi mumkin.
Biroq, taxminan 2013 yilda 3000 mAh dan ortiq smartfonlar paydo bo'ldi. Ayni paytda hatto 5V1.5a ham talabni qondira olmaydi, shuning uchun u yana 5V2A ga uzaytiriladi.
Umumiy fikr 1:
Zaryadlash oqimi zaryadlovchi tomonidan emas, balki telefon tomonidan boshqariladi. Ya'ni, telefon to'g'on, zaryadlovchi esa shunchaki suv ombori. Telefon zaryadlovchining yuk hajmini aqlli ravishda aniqlaydi. Zaryadlovchi yuqori quvvatli va sifatli bo'lsa, telefon zaryadlovchiga yuqori oqimlarni olib o'tish imkonini beradi. Zaryadlovchining chiqish oqimi juda past bo'lsa, telefon zaryadlashi mumkin bo'lgan oqimni ham cheklaydi.
That's why we choose high-power chargers. For example, mobile phones support 5V1.5a input. If you buy a 5V1A charger, the phone can only be charged with 5V1A. If you buy a 5V2A charging head, the mobile phone will control the input current to be only 1.5A, so the charger load is low and there is enough margin.
Yes, I'm talking about Apple. The iPhone 6/Plus has a high charging capacity of 5V1.5a/2A, but the stingy Apple standard charger is only 5V1A. The iPhone 6 has a battery capacity of more than 1,800 mAh, but the iPhone 6 Plus has a battery capacity of nearly 3,000 mAh.
Haqiqiy sinovda iPhone 6 Plus bitta sababga ko'ra iPad zaryadlovchidan foydalangan holda 5V1.9a quvvatga ega bo'ldi: xarajatlarni tejash. Axir Kuk katta pul topadigan yigit. Har qanday aqidaparastning bu masalaga e'tibor bermaslikni istashi kulgili bo'lardi.
For now, the iPhone 6S/6S Plus is likely to follow Apple's lead, as you can buy the iPhone 6S/6S Plus on facebook first and then the iPad charger
Well, let's move on to history. In fact, 5V2A is what Qualcomm calls Quick Charge 1.0 technology. Of course, in fact, in order to prevent charger load, the general mobile phone is limited to around 5V1.8a. The charging technology of Android phone 5V2A has no restrictions, no identification protocol, and anyone can use it.
But apple is an exception, the disgusting apple lighting cable not only has the certification of the charger is certified, the apple device detects that the non{{0}}original charger will limit the current to 5v/1 and 0.5 apple took a very bad supervisor self-interest to deliberately make the hardware certified And software limitations, the general purpose of our devices; brain residue fruit powder don't gossip about your fruit for safety, inferior chargers no matter what, the harm to you and the device is the same! 5V2A and 1A will not make any difference, 5V1A fake Apple charging head electrocuted small news?
So what are Qualcomm waiting for to wake up and make money like this? So private agreements are now in place, which means that if you accidentally buy too many phones, you're going to have to get several different chargers!
Biz hammamiz bilamizki, zaryadlash tezligini oshirishning kaliti zaryadlash quvvatini oshirishdir. Quvvat (Vt)=Hozirgi X kuchlanish. Zaryadlash qurilmasi birinchi navbatda tarmoqni 220V dan 5V gacha pasaytiradi va uni mobil telefonning mikro-USB interfeysiga chiqaradi. Keyin mobil telefonning ichki sxemasi batareyani zaryad qilish uchun taxminan 4,3v ga tushiriladi. Qon bosimini pasaytirish ikkita jarayonni o'z ichiga oladi.
Ilgari zaryadlovchining chiqish kuchlanishi 5V edi. Biz oqimni qanday qo'shishni ko'rib chiqamiz. Ammo u 5V2A ga yetganda, to‘siq paydo bo‘ladi: oqimning yanada oshishi mikro-USB portlari va kabellarining ko‘pligini bosib ketishi mumkin.
