Let us quote https://fmi-standard.org: “The Functional Mock-up Interface (FMI) is a free standard that defines a container and an interface to exchange dynamic models using a combination of XML files, binaries and C code zipped into a single file. It is supported by 100+ tools and maintained as a Modelica Association Project.“
The Batemo Cells FMU (function mock-up unit) is an FMI conform implementation of the Batemo Cell and can thus be used in all supported tools.
