CCCV charger simulation difficulties

Hi!

I am trying to simulate a fast cheger for an electric vehicle battery cell.

Can i get some help with it please? i can't get the constant voltage charging, though the constant current works perfectly (with good current and voltage ripple).

The system works grean on a resistor and a variable resistor, but when i connect the li-ion battery it works only in constant current charging mode. please help!

Thank you!

I am having similar problems with a simpler model. I am trying to do some very simple controls where I limit the current and voltage of a circuit with two batteries in parallel, but different characteristics and different circuits.

The CCCV charger does not follow the limits I have set for the CC and CV input ports.

I am anxious to see what the answer is.

I have the same Problems, did you fix this?

i have same issue, have you solved it ?

Same with me 😭

In 2022b a new product for design and simulation of batteries has been released, Simscape Battery. You can find battery management system blocks such as Battery CC-CV impelmentation and an example with Battery Charging and Discharging.

@Sabin but in the previous version can not use this block (Battery CC-CV)
