Solar Power Bank Circuit Design
The battery has a circuit which controls the power flow obtained from the sun.
Solar power bank circuit design. How to build a solar powered electronic circuit. The following image shows the basic structure of a power bank design. 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. Solar power banks are compact in nature. First one is 5v 500ma solar panel then li ion battery charger breakout board tp4056 then two lithium ion battery 18650. Also these chargers can easily fit into the pocket which makes it easy to carry around.
Power bank circuit diagram. Netia mccray part two in a two part series. 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. This power bank circuit can be built with easily available breakout board.
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.
