Say I have a device that draws 90 amps to operate. It will function with 25 amps as well. I want to limit the current draw from a lead acid battery. I''ve read about rheostats but with this many amps I understand that quite a bit of heat is generated. I also read abit about potentiometers but am not quite sure of the difference between the two.
Using Autodesk Circuits and a lead-acid battery, you can create a circuit that will act as a variable power supply, outputting a range of voltages from 5V to 20V. After creating the power supply you could drive motors using variable voltage, power microcontrollers, logic circuits, LED strings, analog circuits, and much more.
The circuit diagram of the Lead Acid Battery Charger is given below. 7815 The 7815 is a part of the 78XX series of linear voltage regulators. You might have used 7805 and 7812 which produce a regulated voltage of 5V and 12V respectively. Similarly, the 7815 Voltage regulator produces a constant regulated voltage of 15V.
Then we can give the regulated voltage to the battery to charge it. Think if you have only DC voltage and charge the lead acid battery, we can do it by giving that DC voltage to a DC-DC voltage regulator and some extra circuitry before giving to the lead acid battery. Car battery is also a lead acid battery.
Working of the Lead Acid battery is all about chemistry and it is very interesting to know about it. There are huge chemical process is involved in Lead Acid battery’s charging and discharging condition. The diluted sulfuric acid H 2 SO 4 molecules break into two parts when the acid dissolves.
This circuit can be used to charge Rechargeable 12V Lead Acid Batteries with a rating in the range of 1Ah to 7Ah. How to Recharge a Lead Acid Battery? Lead Acid Batteries are one of the oldest rechargeable batteries available today.
Discharging of a lead acid battery is again involved with chemical reactions. The sulfuric acid is in the diluted form with typically 3:1 ratio with water and sulfuric acid. When the loads are connected across the plates, the sulfuric acid again breaks into positive ions 2H+ and negative ions SO 4.
