The MapleSim Battery Library is an add-on for MapleSim that provides advanced, physics-based tools for modeling, simulating, and analyzing battery cells and battery packs. It supports both electrochemical and equivalent-circuit models, allowing users to accurately represent battery behavior under various conditions. The library includes customizable cell chemistries, thermal modeling, degradation effects, and parameter estimation tools, making it suitable for applications ranging from electric vehicles to energy storage systems. Integration with MapleSim’s multidomain environment enables system-level studies of battery performance, thermal effects, and aging, supporting both design and hardware-in-the-loop (HIL) testing workflows.
