این قطعه یک
ماژول شارژر گجت های مختلف الکترونیکی است که دارای پورت میکرو USB با جریان 1 آمپر و ولتاژ 5 ولت برای شارژ شدن خود ماژول می باشد و از پورت USB برای شارژ کردن وسایل الکترونیکی با سطح ولتاژ 5 ولت استفاده می کند.
از این ماژول شارژر و دشارژر پاور بانک می بایست فقط برای شارژ باتری های لیتیومی ذکر شده در قسمت پایین استفاده شود. با وجود 4 عدد LED تعبیه شده در بورد، می توان وضعیت شارژ را نمایش داد.
Description:
The module is used for the charging of a single lithium battery or multiple lithium batteries in parallel, and the charging port can take power from the USB port.
This voltage for a lithium battery is way too low. At this voltage, the lithium battery will have been depleted to approx 10-15% state of charge. Lithium charge algorithms will normally set a return to the bulk voltage of 13.1-13.2V. Just another reason that a standard lead-acid charger doesn’t suit lithium batteries.
For safe charging of a 3.7 V Lithium-ion batteries, they should be charged at constant-current of 0.2 to 0.7 times their capacity, till their terminal voltage reach 4.2 V, later they should be charged in constant-voltage mode till charging current drops to 10% of initial charging rate.
