Charging Circuit Mobile Fast Charger Circuit Diagram
All these batteries are fairly simple to find in most supermarkets.
Charging circuit mobile fast charger circuit diagram. The circuit presented here comes as a low cost alternative to charge mobile telephones battery packs with a rating of 7 2 volts such as nokia 6110 6150. The mobile phone charger circuit based project described here provides 4 7 v of the regulated voltage and a sufficient amount of current for the slow charging of the. But low current charging is preferred to increase the efficiency of the battery. Part list of the mobile charger circuit.
It uses an adjustable voltage regulator so that 6 volt and 12 volt batteries can be charged. For implementing a 4 step fast charger circuit here we employ the versatile lm324 for sensing the different voltage levels. How this 4 step battery charger works. Typically a battery pack sufficiently requires 4 5 volts and 300 500 ma current for fast charging.
Unfortunately every charger circuit is not same some of them contains few extra capacitors or resistors. This circuit is fairly easy to build. The 4 steps include. Mobile phones generally charge with 5v regulated dc supply so basically we are going to build a circuit diagram for 5v regulated dc supply from 220 ac.
The design is quite straight forward built on a paper phenolic pcb could be easily repaired. It s perfect for soldering onto a stripboard. The usb charger circuit works from 6 aa batteries 6 aaa batteries or a 9v battery. This charger can give 5 ampere current for quick rejuvenation of the battery.
Here is a high current charger for fast charging sealed lead acid batteries used in automobiles inverters etc. This dc supply can be used to charge mobiles as well as the power source for digital circuits breadboard circuits ics microcontrollers etc. To charge the battery set the output voltage for charging as 14 volts for 12 volt battery and 8 volts for 6 volt battery. Fast charger circuit diagram.
The circuit described here provides 4 7 regulated voltage and sufficient current for the slow charging of the mobile phone. This portable mobile charger is based on the ic lm2576 voltage regulator ic. The 220 240v ac mains supply is down converted to 9v ac by. Usually the battery pack requires 4 5 volts and 300 500 ma current for fast charging.
1 high current bulk charging 2 moderate current bulk charging 3 absorption charging 4 float charging. You only need 7 components. A fully charged 12 volt battery should have a terminal voltage of 13 5 volts and that of a 6 volt battery 6 5 volts. How to build the charger circuit.
Transistor t1 is used to give the regulated output. Lm338 on heat sink. Setting the output voltage. But even though you can get a clear overview of the mobile charger circuit from the above diagram.
