    How to calculate the battery nominal voltage and rated capacity?

    • @pzengineering2020
      @pzengineering2020  ปีที่แล้ว

      The battery nominal voltage an rated capacity do not need to calculate, unless you are sizing battery energy storage system for a specific load. Can you elaborate your question

    hi sir, may i know how the PWM works? if we calculate the duty cycle value, we will get the numbers. but then how do we know the product of PWM is the same with the calculated duty cycle? as i can see in the video, u use battery current.. bit confusing and still learning, hope u can help

    • @pzengineering2020
      @pzengineering2020  2 ปีที่แล้ว

      Hi thank you for your comment, The PWM is determined by the switching frequency and period, which is the same used to calculate in general the Duty cycle. I think you should just be sure about your calculation which should be the same with simulation.

      @@pzengineering2020 then, i need to make sure my battery current needs to be constant in one value only? because I know if the current is sinusoidal the PWM output would have an irregular pulse

      your method is incorrect.
      U didn't show simulink block for them correctly.

    hello,why do you compare the current and the voltage ? it is not homogeneous in your regulation loop

    • @pzengineering2020
      @pzengineering2020  3 ปีที่แล้ว +1

      Hello, Thank you for your comment .. We are not comparing current and voltage, what we are doing is to compare Vbat vs Vref connected to PI Controller in order to generate the reference current. We are more focussed in generating reference current. I hope it's clear and you are more welcome to ask... Regards

    Hi PZ Engineering
    Hope you’re doing well.
    I have some confusion over your control circuitry, can you please make it clear.
    First, you have compared 13 and 12 with Ilib_ref in your controllers, why is that so?
    As for my understanding, 13 and 12 are the voltage values. How do you compared voltage with current?
    Can you please rectify your circuit?

    • @pzengineering2020
      @pzengineering2020  2 ปีที่แล้ว +1

      Hello thank you for your comment, In my control, the main focus was to have a reference current. Was more about discharging and charging reference current. at 13 suppose to be voltage not current. Will rectify in the next videos. However, I hope you got the idea

    Can we charge the battery with higher voltage supply??
    We are using A Bidirectional Buck Boost, it should reduce the voltage level in opposite direction

    • @pzengineering2020
      @pzengineering2020  3 ปีที่แล้ว

      helo, thank you for your comment, The battery normally needs to be charge with a slightly higher voltage. We need to be aware, we should not charge battery with very high voltage, it will damage the battery, consequently reduce it's lifespan. the use of buck and boost is the solution to reduce the high voltage to a slightly high voltage to charge the battery.
