To Mr. Swagatam Majumdar :
I would like to ask and look forward to you to be made Automatic cellphone charger circuit 5 Volt and Automatic Lead Acid Battery Charger Circuit 12 V (in the schematic circuit and the first transformer CT) automatic / cut off by using a battery indicator and
LED lights red as an indicator were charging (Charging On Indicator) using IC LM 324, and
LM 317 and a full battery using a green LED and breaking electrical current when the battery is full.
For cellphone charger circuit 5 Volt I want to have levels of the following indicators:
0-25% battery is in the charger using a red LED.25-50% using a blue LED (red LED goes out)55-75% using a yellow LED (LED red, blue outages)75-100% using a green LED (LED red, blue, yellow outages).next to Lead Acid Battery Charger Circuit 12 V I want to use the 5 LED lights as follows:0-25% using a red LED25-50% using orange LED (red LED goes out)50-75% using a yellow LED (LED red, orange outages)75-100% using a blue LED (Led red, orange, yellow outages)more than 100% using the green LED (LED red, orange, yellow, blue outages).
I hope you, the components are common and accessible and made a circuit schematic above as soon as possible because I really need schematics details.
I hope you will help me to find a better solution. Thank you.
The requested 12V automatic battery charger circuit with 4 LED indicators make use of 4 level status indicator and can be witnessed below.The TIP122 controls over-discharge of the battery while the TIP127 ensures an instant supply cut-of for the battery, whenever an overcharge limit is reached for the battery.
