Charging model for Li ion battery

Is there any good model to simulate charging process for Li ion battery in simulink, where I give current as input and get SOC, voltage and power-loss at each time step.

In charging process, once battery reaches 4.2 volt (or maximum voltage which is battery specific), the process should continue with constant voltage process and without current input, but till it reaches 4.2 I should be able to give current at each time step.

I tried electrical equivalent ciruit available in power train systems, but I am not abe to model the Constant voltage process after battery reaches threshold value.

A good place to start is:

From R2022b, a new toolbox called Simscape Battery has been introduced. This product can be used to design and simulate battery and energy storage systems. There are many examples that can be used as a starting point.
