Solar Power Bank Circuit Design

Solar power banks are compact in nature.

Solar power bank circuit design.

How to build a solar powered usb charger for phones and other small devices. Oct 31 2017 this power bank circuit pcb board has two main parts one is power bank battery charging circuit which is made by using tp4056 and second is dc to dc boost converter part which is made by using xl6009. Last year our team at mbadika was working on an idea to help aspiring young innovators and entrepreneurs learn the basics of product design and development. This block diagram describes about the power bank design.

Power bank circuit diagram. How to build a solar powered electronic circuit. Solar power bank is a device that converts solar energy into an electric energy and stores it in a battery. Below is the circuit diagram for our power bank.

As can be seen in the above design a charger circuit charges a 3 7v cell once the charging is completed the 3 7v cell box is carried by the user while traveling and whenever the user s cellphone battery goes down he simply connects this 3 7v cell pack with. The term 18650 cell is due to the cell dimension it is cylindrical in shape with 18mm diameter and height of 65mm. The following image shows the basic structure of a power bank design. Netia mccray part two in a two part series.

The battery has a circuit which controls the power flow obtained from the sun. As we can see its fairly easy to make a power bank with li ion battery tp4056 module and a boost converter.
