6 Frequently Asked Questions about “Battery charging current limiting fault”
What is the current limit of a battery limiter?
The current is limited to approximately 1A (≈1.25V / R2) in this battery limiter. Note that the minimum voltage drop across the limiter is about 2.5V. In your design, the point where the current starts to drop is the constant-voltage value from your regulator.
What happens when you limit the current?
When you limit the current, the voltage will consequentially be less than it would have been without the limiting. A simple current limiter can be made with a LM317 IC regulator (LTspice simulation below). It can be installed between the input supply voltage and your constant-voltage circuit.
How much current can a battery charger provide?
Normally you would not expect more than 3A from such charger, however since there are large capacitors at the end of its internal circuit, charger is capable of providing higher inrush currents. To account for all this information I have set the current limit to 4.2A.
Can a 3A Charger power a current limiter?
I have a 3A charger powering the current limiter. Normally you would not expect more than 3A from such charger, however since there are large capacitors at the end of its internal circuit, charger is capable of providing higher inrush currents.
How do you limit a drive voltage?
In place of or as well as the cycle by cycle limiter you could add a low side load current sense and use that to limit drive voltage so that the target load current is provided. The easiest method may be to provide a bank of switched resistors which can be binary switched to limit load current to 20A.
How many volts does it take to charge a battery?
You'll lose at least 1.7v from IN to OUT, and another nominal 1.25v from OUT to ADJ, so that's roughly a 3v drop. Your charger will have to be putting out at least 17v to charge the battery up to 14v. A good circuit for battery charging is a constant voltage circuit with current limiting. A few op amps and power transistors can do the whole thing.
