Fuel cell control unit

Dynamic and efficient fuel cell operation

Taking the electrical and thermal power requirements from the vehicle control unit and the system’s current sensor values, the FCCU controls and monitors the connected system components, such as the hydrogen gas injector, electric air compressor, recirculation pump, sensors, etc., in order for the fuel cell to provide the requested amount of electrical power.

Here, the FCCU’s open- and closed-loop control software incorporates functions based on physical models. Fast control loops enable the kind of highly dynamic fuel-cell stack operation required for modern electric vehicles.

Ease of adaptation and integration into existing and future E/E architectures of electric vehicles

With a software architecture that is modular, ASPICE-compliant and prepared for the AUTOSAR standard, it is possible to easily integrate the FCCU into future E/E architectures and flexibly adapt it to any additional requirements.

The central software functions are self-learning, which facilitates simple, economical calibration and a quick time-to-market, particularly if the system must be adapted further.
