Lithium Polymer Battery Charger Circuit

Its sop 8 package and low external component count make the tp4056 ideally suited for portable applications.

Lithium polymer battery charger circuit. Knacro ac dc 12 6v 1a adaptor li ion battery charger 3 series 12 6v 1a polymer lithium battery charger. Lithium ion polymer batteries are extremely power dense. The tp4056 ic is a complete constant current constant voltage linear charger for single cell lithium ion lithium polymer liion lipo batteries. At the heart of the circuit is one microchip mcp73831 available in sot 23 5 package.

However they are not safe batteries and require extra care. 4 6 out of 5 stars 14. Free shipping on your first order shipped by amazon. 4 4 out of 5 stars 22.

When the ic 555 is used as a comparator its pin 2 and pin 6 become effective sensing inputs for detecting the lower and the upper voltage threshold limits depending upon the setting of the relevant presets. This makes them great for reducing size and weight of projects. The following li ion battery charger circuit very efficiently follows the above conditions such that the connected battery is never allowed to exceed its over charge limit.

Charging or using the batteries incorrectly can cause explosion or fire as shown by this and many other youtube videos. Fully charging a battery can take from 2 to 4 hours depending of the charge rate which i recommend to keep between 0 5 and 0 7c. In this project we will build a two stage battery charger cc and cv that could be used as to charge lithium ion or lithium polymer batters. When the current flowing into the battery is less than 3 10 of the nominal capacity the battery is 100 charged and the circuit above is what will tell us when this happens.
