How to integrate PCM in battery thermal management system sucessfully ?

Objective: Integrate a Phase Change Material (PCM) into the Simulink model EVBatteryCoolingSystem.slx to improve battery thermal management by leveraging latent heat absorption.

Issue: Persistent sscbuild errors ("Cannot find MATLAB namespace 'PCM'") despite:

1. Creating a custom PCM component (PCM.ssc) with parameters for melting temperature, latent heat, and mass.
2. Organizing folders as +PCM/PCM.ssc (MATLAB package directory).
3. Repeated attempts to compile and integrate the PCM block into the Battery subsyste

• Namespace/directory compliance issues during compilation.
• Uncertainty about PCM code syntax or structural errors.
• Difficulty validating PCM behavior in simulations.
• how to resolve namespace errors, validate PCM code/structure, and ensure correct thermal network integration.

would you be able to share the .ssc file so the community can reproduce your issue and advise?

here i have uploaded my .slx file i have constituted an model for PCM which i created

Hi Ali, there isn't any custom .ssc or library associated with what you shared. are you able to share the PCM.ssc file that you mentioned to reproduce the sscbuild errors?
