Lm317 Battery Charger Circuit Diagram. According to the battery manufacturers a battery should be charged with only 1 10 current in ampere of its ah value. Here too we employ the ic lm317 although this device is used only to generate the required regulated voltage and current for the connected li ion cell.
It use ic lm317t hot ic control current less 300ma size battery 2 4v 4 8v 9 6v. Here too we employ the ic lm317 although this device is used only to generate the required regulated voltage and current for the connected li ion cell. The complete schematics of this battery charger circuit are shown below.
Battery charger circuits reverse polarity circuits variable power supply motor control circuits are designed using lm317 ic.
By using two lm317 ic s you can regulate both the positive and negative swings of a sinusoidal ac input. Here is a simple but effective battery charger circuit using ic lm 317 the circuit can be used to charge 12vlead acid batteries the circuit is very simple and can be easily assembled on a general purpose pcb. The current controlled 12v battery charger circuit using ic lm317 presented here shows how the ic lm317 can be configured using just a couple resistors and an ordinary transformer bridge power supply for charging a 12 volt battery with utmost accuracy. It can be used to charge 12v batteries.
