I have a question about internal resistance measurements, if i understand correctly you measure voltage before and after applying known load to calculate internal resistance? I started planning my own discharger, however yours seems to be better in any aspect (except i would add sd card reader so i can see data on my pc later).

@@cekpi7 The voltage of a battery drops when it is loaded. So you need to measure the battery voltage without a load (Vo), and the battery voltage (Vr) with a known load (R). Then using Ohms law you can calculate the Current C=Vo/R. Finally you can calculate the internal resistance (Ri) using Ohms law again. Ri=(Vo-Vr)/C. In other words, you can just calculate the internal resistance using a multimeter and a power resistor. 😁

Sir can we set any cut off voltage in it? Because I need to charge my drone batteries and as u know I can't overcharge any cell they need to be balanced

Good Morning ​I am putting together the system you put on. I'm doing it in stages to understand the circuit. I started with the battery discharge system. I did not understand the function of the LM358 connected to analog port A0. I know that the analog port A0 is for measuring the battery voltage but why the connection with the LM358's non-inverting port? Wouldn't it be easier to connect the A0 directly to the battery positive? I also did not understand the need for a second IRLZ44N MOSFET whose output is connected to gate of the LM358. The function of the potentiometer is also a mystery to me. I would also like to know how you can perform a constant current discharge. ​Thank you very much for your help.

@sasiskas

3 жыл бұрын

1. Pin A0 is connected to battery positive , using a voltage divider. That was done to protect your Arduino in case you accidentally use a battery with a voltage higher that 5V. In other words, yes you can connect the A0 directly to the battery positive but you will be missing a "safety feature". 2. The LM358 works as a voltage comparator. When V+ (1v) is higher than V- (0V) then the Output is High (~4V) and makes the Drain to Source path of the Mosfet conductive(MOSFET is ON), so current flows through the resistors. When current flows through the resistors the V- is higher than V+ then the Output is LOW and MOSFET is OFF.....then again the V+ is Higher than V- and you end up with a loop of ON and OFF of the MOSFET with a very high frequency (~100Khz). In a few words, V- always tries to stay at the same level as V+ (1V). Knowing the Voltage(1V), and the resistance(1 Ohm), I just use Ohms law to calculate the discharge Current of the battery (1A). So by adjusting the potentiometer, you can set the discharge Current for your battery.

Thank you for your project , it is helping me a lot. I put everything on the protoboard and started testing with the load. I noticed that the current does not appear on the display. I put my ammeter in series and at the beginning of the load the current was 240 mA. When the load advanced the current went to 150 mA. I tried to vary the current by moving the trimpot but it didn't change anything. - I haven't finished the first load yet, but as I'm hurried I start asking: Is it possible to control the charging current? Should the current remain constant during charging? I noticed that the display is missing the current value during charging, I will try to change it. I ask this because I intend to change the program to get voltage values ​​as a function of time to have the charge and discharge curves of the batteries but for that I need constant charge current.

for controlling the charging current you need to change the resistor Rprog of the TP4056 module (you can use a trim pot) For more information look at page 2 of the datasheet. dlnmh9ip6v2uc.cloudfront.net/datasheets/Prototyping/TP4056.pdf

Nice question. I used 10 x 10ohm resistors in parallel. Which is equal to 1ohm of resistance. I used 10x10ohm 2watt resistors instead of one 1ohm 10watt (you cant use one 5watt resistor, it can't handle the wattage) for two reasons: 1. because it is cheaper than using one high wattage resistor 2. because ten resistors in parallel have better precision than only one resistor. So yes, you can use only one resistor if you want, but it is going to be more expensive and less precise.

So after all it was the bad connections that caused the issues. The safest lowest voltage is ~2.8V (at idle). So 2.3Volts during discharge is equal to approximately 2.8V at idle. This is something that can be changed within the code, if you believe that it too low.

If everything is connected as shown in the diagram, there is no charging current and the blue and red LEDs on the TP4056 starts to flicker slightly. Is that because of a defect in the IRF or TP4056?

I have problem with inaccurate readings as general battery voltage is off, current reading are off. For example in discharge rate current on the lcd goes to 1,2A but on max poti read with amp meter close to 1.3A witch is normal because battery voltage readings are off.
