Cell Voltage Simulation IntelliSim

CVM Modules

For the commissioning and testing of cell voltage measurement electronics and FuelCell control units, and in particular for the software testing of such ECUs, it is necessary to simulate cell-specific voltage values. The simulation modules of the MCM IntelliSim series, in conjunction with a master module enable active simulation of a fuel cell stack without the need to integrate a real stack into the test environment.

The modularity and the individual isolation of the channels for each module allow the simulation system to be configured to suit the respective test object. The Intellisim U06AII is designed for the development and testing of fuel cell systems and can be easily adapted to new requirements at any time.

The design was developed for high channel numbers with a focus on a favorable channel price. It follows the successful modular design principle of the MCM Intelliprobe product family for single-cell voltage measurement, which is used worldwide by manufacturers of fuel cell vehicles and their suppliers.
