Through the development of the Powertrain Control Unit and all embedded software, we are able to provide the integration of the fuel cell in your vehicle.
Dumarey Hydrocells’ dedicated Fuel Cell team is comprised of specialists across a range of different expertise, giving us the benefit of a comprehensive system architecture when it comes to: Energy Management System (EMS) control, Virtual Analysis, High Voltage/Low Voltage, Active Thermal Management and Total Cost of Ownership Analysis.
This allows Dumarey Hydrocells the flexibility to work with many different products and supply new integrated solutions or optimize existing ones.
Hybrid Propulsion Control Unit (HPCU) for Fuel Cell Powertrain & Embedded Advanced Control Software
Hybrid Propulsion Control Unit (HPCU) is the core controller which manages the full propulsion architecture for fuel cell hybrid vehicles. The in-house model-based embedded Software allows Dumarey Hydrocells to develop a customized solution and to control all the fuel cell propulsion subsystems. Embedded advanced control techniques, like Model Predictive Control (MPC), are used to optimize Energy and Thermal Management subsystems. Customized embedded Software can be even integrated into customer’s controller.

Energy Management System “MPC-based”, for optimizing electric power spilt between Fuel Cell and Battery: best trade off among efficiency and durability
High Voltage/Low Voltage Modular Power Distribution Unit (Dumarey Hydrocells PDU)
Power Distribution Units in BEVs or FCEVs are used to distribute High Voltage between power supply (High-Voltage Battery or Fuel cells) and Loads (i.e. E-drive, Heaters etc). These are usually strongly customized based on application.
Dumarey Hydrocells Power Distribution Unit Modular, based on proprietary design, allows it to easily expands the number of High-Voltage I/O ports according to costumer’s requirements in terms of I/Os and packaging constrains.
Dumarey Hydrocells PDU embeds the capability to distribute and regulate different High Voltage levels (i.e. 700V-400V) and Low Voltage levels (i.e. 12V and 24V).
The Fuel Cell Test Bench is fully modular and scalable: different power levels and powertrain architectures (HGV, Buses, Railways and others) can be tested and calibrated, including real driving cycle simulations, leading to a significant reduction of Vehicle Customer Development Time.

A “State of the Art” Fuel Cell Dyno bench is one of the first capable to manage multiple levels of high and low voltage, high quality Hydrogen fuel and up to two independent fuel cell systems. It features highly sophisticated and advanced cooling systems, all governed by a proprietary Powertrain Control Unit (PCU) Software which embeds at the same time.
One of the key benefits of our Fuel Cell Test Bench is that it is fully modular and scalable: different power levels and powertrain architectures (such as HGV, buses, railways and others) are able to be tested and calibrated, including real driving cycle simulations. This leads to a significant reduction of Vehicle Customer development time.
