For commissioning and testing cell voltage measurement electronics and fuel cell control units, especially for software testing of such ECUs, it is necessary to simulate cell-specific voltage values. The simulation modules of the MCM IntelliSim series enable active simulation of each cell of a fuel cell stack or battery via CAN or in conjunction with a master module for higher cell numbers or data rates, without the need to integrate a real stack into the test environment.
The modularity and individual isolation of the channels per module allow the simulation system to be configured to suit the respective test object. The Intellisim U06AOI is designed for the development and testing of CVM assemblies and associated fuel cell systems and can be easily adapted to new requirements at any time. In combination with the MCM-U06ABI expansion module, balancing currents up to +/- 300 mA can also be simulated in battery cell voltage simulations.
The design was developed for high channel counts 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.
