With test systems for Fuel Cell Control Units (FCCUs), developers can test the electronic components of fuel cell or battery systems without needing a real system. An essential component of the systems we develop for our customers is therefore cell voltage simulation (CVS). In addition to the cell voltages, the relevant environmental parameters are also simulated.
With the HiL system shown here, fuel cell controls based on a SIMATIC S7 can be tested without having to set up a real fuel cell system. We develop FCCU-HiLs for the areas of:
The system marries the CVM modules for recording and simulating cell voltages on fuel cells with the I/O modules of the MCM product family. The latter simulate operation-relevant environmental factors such as pressure and temperature as well as certain switching states and measure the outputs of the controller.
