Have you ever tried to design a battery charger which charges the battery automatically when battery voltage is below the specified voltage? Below charger automatically shut off the charging process when battery attains full charge. This automatic battery charger circuitA is mainly involves two sections a€“ power supply section and load comparison section.
Lm317 voltage regulator output is applied to the battery through the diode D5 and resistor R5. If the battery voltage is below 12V, then the current from LM317 IC flows through the resistor R5 and diode D5 to the battery. When the battery voltage rises to 13.5V, the current flow to the battery stops and zener diode gets the sufficient breakdown voltage and it allows the current through it.
Now the base of the transistor gets the sufficient current to turn on so that the output current from LM317 voltage regulator is grounded through the transistor Q1. The output voltage of the battery charger should be less than 1.5 times of the battery and the current of the charger should be 10% of the battery current. An Automatic Battery Charger Circuit for sealed lead acid batteries is mentioned in this project. When the charge in the battery falls below 13.8V, the output of LM358 is high and the output of 555 is low. The AC supply is converted to 15V DC with the help of transformer and bridge rectifier and the Green LED is turned on. This is important as SCR stops conducting only when the supply voltage is 0 or disconnected from supply and it is possible only with pulsating DC. This is filtered with C1 and when the potential reaches 6.8V, Zener ZD1 starts conducting and supplies enough Gate voltage to SCR2 to turn it on. As a result, the current flows through SCR2 via R2 and SCR1 is turned off as both gate voltage and supply voltage are cut off.


In the scehmatics of LM317 based 1st Project, I am not able to locate POT, its connections and its value. Hi , I am just curious to know if this could be used to charge 2 12 volt slap batteries in series with the input voltage coming from the pedaling of a bicycle connected to a motor with the polarities reversed in order to create voltage. Now the 10K adjust the voltage very well but without SCR the red LED only turns off when it is higher than 13 V. Download the firmware  here Flashing Instructions - MAKE SURE TO BACK-UP EVERYTHING BEFORE YOU PROCEED!!! Before continuing, download and install the LedControl Arduino library as it is essential for using the MAX7219.
When the battery connecter to the charging circuit, the battery will not be dead completely and it will get discharged this will give the forward bias voltage to the transistor through the diode D2 and resistor R7 which will get turned on.
I tried my hands on this circuit but the output voltage was just 6volts pls how do I achieve a 12volt output? This unregulated DC voltage is now applied to the LM317 variable voltage regulator to provide regulated DC voltage.
The output voltage of this voltage regulator is varied by varying the pot 10k which is connected to the adjust pin of LM317. Now base of BD139 NPN transistor gets the current through the zener so that the total current is grounded. At this time zener diode D6 will not conduct because battery takes all the current for charging.
Battery charger should have over voltage protection, short circuit protection and reversed polarity protection.
The 15V Zener diode is used to set the LM317 to supply 16.2V at output in the absence of load. LM336 is used to supply a reference voltage of 2.5V to non-inverting terminal (Pin 3) of LM358. When SCR1 is conducting, 15V DC will flow through the battery and the battery starts to charge.


All what you need is to change the circuit to 5 volt output and it come on different circuit.
The light dependent resistor will have high resistance in darkness and low resistance in the light.
So if you want to charge your battery with AC source then should follow these steps, we need first limit the large AC voltage, need to filter the AC voltage to remove the noise, regulate and get the constant voltage and then give the resulting voltage to the battery for charging. When the 2N4401 is turned ON by the output of 555, the ADJ pin of the LM317 is grounded and its output voltage is 1.3V. A voltage divider network is used to supply a portion of batterya€™s voltage to inverting terminal (Pin 2) of LM358. Batteries with different potentials like 6V and 9V can also be charged by choosing appropriate components. When the charge on the battery is almost full, it opposes the flow of current and the current starts to flow via R5. I will try to charge my 12V battery from my wind tribune I have build with used electronic devices’ components. The comparator used here has LDR connected to its inverting terminal and potentiometer connected to its non-inverting pin. It has 8pins.In these eight pins pin 1, 2, 3, are used by the first op-amp and 4,8 pins are common for both the op amps. NPN transistors are initially open circuited that is when there no base voltage, there is no flow of current from emitter to collector. Here, base is connected to the output of the LM358 IC through a resistor of 10kohms.Emitter is connected to the ground.
