12v car battery charger circuit diagram 5000w,interstate deep cycle marine battery amp hours,cheapest car batteries in adelaide oval - Step 2

The circuit has been designed to construct a practical mechanism that can easily and automatically charge batteries rated at 6 V or 12 V used in automobiles. One of the essential factors in the operation of this circuit is the utilization of transformer denoted as T1 which has excellent resistance and insulation for short circuits making it a good quality. The transistor Q1 is conducting through voltage divider R1 and R2 while trimmer TR1 and resistor R4 are functioning as regulated current source.
When the charging applied reaches 14.4 V, the circuit parallel to the battery will be triggered, which consist of R6, D2, D6, and D8. The charging current of 1.2 A should be adjusted by the trimmer TR1 with the use of a 6 V battery. It is very important to note that dealing with batteries will always bring danger of explosion, so proper handling and care is a must. Here is the circuit diagram of a simple and straight forward 12 V battery charger circuit with diagram. 12v 65 ah ka battery kese charge kar sakte he….12 v trnsformer se direct charge hoga kya?
Hi friend,I want to make a stand alone 6v bike battery charger cum DC to AC-5A circuit.Could you please help me?
Have you a modified Circuit to show the placement and value of the resistor mentioned by the person “Leandro” ? Also I am wanting to also build a 6 volt charger, for a 6v Gell type of battery, similar in size to a motor bike battery. Can you tell me the Different Transformer and Resistor Value, and whether I should fit a Zenner in the circuit ???
The above circuit claimed have ability to prevent battery overcharge that make electrolyte lost due to evaporation. Am so greatful for this charging circuit diagram thanks a million, pls send me the part list.
Hi thank you very much to publishing the car battery charger circuit diagram, would you please give me the components specific value and correct parts number. Setting up a webcam sight illuminator over your laptop's webcam will certainly “enlighten” your online conversations. The power input of T4 (2N3055) is the product of load current and voltage difference already mentioned.
I want battery charging circuit in petrol engine vehicles by using electrical solenoid coil, connected to Motor with propeller shaft of engine & alternator. First of all thanks very much for sharing this, I bet I will try it but I need to know about that byx21-40 ? Unfortunately, a PNP type will not work since the base should be more negative than emitter in order to turn it on.
T1 should be PNP (not NPN BC107) and if so, the base and emitter inputs must be swapped to make it work.

This battery charger circuit can be used to charge one or more batteries with the total nominal voltage of 12 V, meaning ten NiCd battery or six 2 V lead acid. We can use a transformer with 18 V on the secondary and then using a diode bridge to rectify the 18V ac voltage we get 22V dc on C1.
The completely discharged batteries are charged at the begining with a 6 mA current thru R2-D2 and R4-R6-D1. If the battery is connected with reversed polarity or there is a shortcircuit, the power transistor T1 remains blocked and the charging current can not exceed 6 – 12 mA.
While might be good for charging NiCd batteries (that I don’t Know), this circuit is useless for 12V Lead Acid Batteries(that I do know well).
You must have used some strange datasheet if you say that BD140 is NPN… It is PNP and has been like this from its birth, when the silicone met the plastic case for the first time. It is responsible for transferring electric energy or alternating current from one circuit to another via conductors that are coupled inductively. The Darlington pair of power transistors Q5 and Q6 is being driven by a current through R9. The indication of complete charging of the battery will show in LED D8 as it conducts simultaneously upon charge completion. This circuit can be used to charge all type of 12V rechargeable batteries including car batteries. I build that one but i think the power of the battery go back to capacitor and i plan to put some diod in possitive side. If you want to limit to any other current level you have to use a sensing resistance and a transistor similar to the one used in our earlier article, which can be adopted for 12 volt also. This circuit will eliminate the problems by monitoring the battery’s condition of charge through its retroactive control circuit by applying a high charge current until the battery is completely charged. Charging current will substantially exceed line current due to voltage matching provided by transformer turns ratio.
A transformer is composed of two or more coils of conducting element, like a wire, wrapped around a core where a magnetic field is produced by an alternating current in one coli. A Darlington pair is designed in such a way that the collectors of both transistors are attached together and the emitter of the first transistor is directly coupled to the base of the second or output transistor.
In the absence of a 6 V battery, a charger can be used that will pass through the ampere meter to achieve the adjustment of TR1 to 1.2 A.
The circuit is nothing but a 12V DC power supply with an ammeter for monitoring the charging current. And i wonder to know if it isnt dangerous to make this circuit without any resistence like in this diagram. When charging is complete, it turns on the red LED (LD2) and deactivates the charging circuit.

They are the connections of the transformer to the circuit board, and those supplying current to the battery being charged.
Excessive charging current is avoided because the current value on T3’s base is limited. The incorect usage is impossible: connecting the batteries with reverse polarity, shortcircuit of the output terminals or power loss have no impact on the charger or battery. Open the regulator, replace the 56 Ohm resistor marked as VR1, with a 100 Ohm trim pot, via two tiny wires.
The base current of the output transistor is equal to the emitter current of the input transistor. These connections should be made with cables having a large cross-sectional area to prevent voltage-drop and heat build-up when current flows through them. A car battery charger is normally around 6 V to 8 V while the current is around 1.2 A being handled by the trimmer TR1. The current across the base of Q5 will be very minimal when the voltage reaches around 15 V, which will stop the battery for charging. As the battery is charged slowly, the voltage is gradually increasing until it reaches 7 V, which would cause D1 to conduct. To protect the battery from short circuit or high voltage, diodes D5 and D6 are used while D6 is used for misplaced error from battery poles. The increase in voltage results to the decrease of voltage across R3 which makes Q1 to conduct. If TR1 is not enough and current adjustments are causing difficulties, the value of R4 can be altered until the desired charging current becomes 1.2 A. Diode D2 which possess 6.8 V can be shorted by closing switch S2 for charging of 6V battery.
Because of this fact, Q5 and Q6, together with bridge B1, should be placed on a heatsink with the isolation of a suitable silicon mica capacitor.
Since the transistor Q5 is grounded, the excess current across it would remain constant for modification. Since the current in the circuit is large, the PCB and bridge should be connected with thick and short cables, as well as using a wide enough PCB.
I have more than one car, and while not in drive I trickle the battery to keep at 12.9 V on REST (without charging element). The whole circuit should be enclosed in a metal casing with dimension that has enough ventilation. Periodically you have to equalize the elements of Battery, This can be done increasing the charging voltage, periodically, to 14.5 V for 2 hours.
