You're doing good job Sir God bless you. Actually the video that people are looking for is CCCV combined, first step begin charging the battery with bulk current until open circuit voltage of the battery is reached then switch to constant voltage and continue charging in this mode with less current. The current in the CV mode should continue to decrease until zero or to a certain preset value (a very small value) to indicate that charge is complete. My idea is to take CC part-1 of your video and combine it with CV-Part2 of your video. Then use switch to switch between the two modes. First we sense the soc of the battery, if soc=85% then battery should charge in CV mode and then switch will pass signal2 (which is the control loop of the cv mode in part2 of this video)...Instead of the soc..one can use the battery voltage to do the switching..if battery voltage is at xyz amount then do CC else do CV What do you think about this idea? You can also do a buck converter to charge the battery in CC-CV mode by applying the same logic here ch.mathworks.com/matlabcentral/fileexchange/35735-charger-for-battery-48v-from-dc-source-32v-with-two-mode-cc-and-cv but instead of boost, use BUCK CONVERTER...that's all. As you can see people are requesting for this video and i hope you can spare some time for us and help. God bless you and good luck and keep the good work!
Can you combine this part 1 and the part 2 to make one CC-CV charging? System should automatically switch from CC to the CV mode once the open circuit voltage of the battery is reached or when the SOC is between 80-100%.
You never have to be sry for asking us remember that we're here to help each other 😄 PI Controller tuning to another value around the specified values will not change the final result, what will change is the rise time, delay time and the maximum overshoot, hope this helps 😄
Dear Sir . First of all, thanks for this great video. I have a question, is it possible to use a full wave rectifier circuit output 48 volts DC to charge and discharge this battery instead of using a constant voltage source. please answer
hello sir, can you make the video of constant current- pulsing current-constant voltage charging. so at 20% of battery capacity we use CC then 20-80% using pulse current, then 80-100% of bat capacity using CV. i happy to learn how to change the mode of CC-PC-CV Charging and Schematic circuit of this charging method btw, great video, nice explanation.
Thank you for the video. Nice explanation. I have a doubt like i am using MATLAB 2014. There, I am not able to connect Mosfet gate and goto block. What may be the reason?
Another great video, but I was wondering how you determined the values that you were placing into the model? Are you using a particular battery specification?🤔
Good bro.....nice job however if possible then give some hints how to calculate the parameters you are inserting in the simulation blocks it would be good for the beginners.
@@TheUrbanScholar well tbh i want to design a solar system and need to generate power if i connect rlc load with your system and measure my power will that power would be correct one\?
Sir Please tell me is SOC is increasing in this?. .with constant current ...as in the result we saw 83.89+++ and goes in increasing whilw we gave the 85% initial charge help me out i m confused

@Mojil Shah Hey! So as you can see in the dialogue box of the PID controller there is something called as P as well and I as you mentioned is integrator. These are constants. Commonly referred to as Kp and Ki. You can use the PID tuning which is a relatively new feature on matlab to get the constant values
@Mojil The integral term in the PID reduces the steady state error. Basically you get closer to the desired value with the proportional term (P) and then you achieve the exact value using the Integral term (I). For further informations you can google videos about empirical PID tuning.
Thank you sir If you can help me i want to create a model for utilizing regenerative braking energy, for example, braking a train to charge a battery or something else
Apologies,even we don't have expertise on this so we can't answer your question🙁 But whatever we have expertise in rest assured, we'll put it across in the best way possible 🙂

Hello sir, this video really interesting! good job :) I hv a question.. Is it possible if we combine boost converter cct (boost the input voltage from source) with a charging cct (use the boost output voltage to charge a battery)?
It will work on simulink and it'll work practically, but this system can't be combined with other applicances for practical purposes as it doesn't have current control or voltage control, do let us know if it cleared your doubt 🙂

Thank you so much Fabio!

Dear Sir
Please is it possible to apply the same control circuit to charge a 48-volt battery from a full rectifier circuit.
Nice video thanku one thing I want to tell u can use proper equations to tune PI Controller u will get more smooth DC output
Why SOC is not increasing here as we are charging the battery
Can you combine this part 1 and the part 2 to make one CC-CV charging? System should automatically switch from CC to the CV mode once the open circuit voltage of the battery is reached or when the SOC is between 80-100%.
yea bro i too need that concept and i am working on it coudn't find MATLAB code i tried to code by myself but ended up with error
