Design and validation of powertrains and peripherals for electric vehicles
Your expectations
In order to reduce the CO2 emissions of your vehicles, you need to:
- Validate your mechanical / hybrid / electric power trains or their components
- Design and validate hydrogen storage systems and tanks
- Carry out multiphysics tests to validate the thermal systems of your vehicles
Our solutions
As a long-standing testing partner for the automotive industry, Cetim has has been carrying out tests on complete power trains or some of their components for more than 15 years. Today, these tests and analyses performed on gearboxes and differentials are now supplemented by tests on high speed gear reducers, rotors, thermal heating systems and, more generally, with multiphysical tests under power electronics load. Our experts also provide their know-how regarding the efficiency measurement and improvement.
Thus, Cetim has contributed to reducing carbon emissions for several years through:
- Its range of high power / high speed tests (high speed spindle: 250 kW, 20,000 rpm, and adjustable battery simulators up to 250 kW)
- 48V hybrid gearbox tests
- High speed gear reducer tests: bearing / pitting / power axle failure
- Gear motor tests
- Its range of combined tests involving several stresses (e.g. climatic, vibratory and electrical environments), including specimen instrumentation and associated parameter acquisition systems.
- HV electrical testing up to 1500 V
- Its full support in the design, validation and industrialisation of hydrogen storage systems in thermoplastic composites, incorporating integration of a “Life Cycle Analysis / Circular Economy” approach
- Analysis and advice on particulate cleanliness of H2 components and tanks.
ZOOM ON HYDROGEN
HyMEET, our technological platform dedicated to H2, provides mechanical engineering with resources and skills needed to master low-carbon hydrogen production, distribution, storage and utilization technologies. HyMEET combines an ambitious R&D program with a €25 million investment in resources dedicated to characterization and validation tests (up to 1000 bar and in a range of temperatures from deep cryogenics to high temperatures) as well as consulting and training.
Its activities are dedicated to:
- Characterizing the behavior of materials in contact with hydrogen
- Development of specific test methods
- Characterization of specific mechanical equipment and systems in severe hydrogen environments.
Our equipment enables:
- Mechanical characterization of materials using fatigue machines in a high-pressure hydrogen environment
- Control of sealing systems and plant containment, with test benches developed to study gas diffusion phenomena, resistance to rapid decompression and sealing performance under severe conditions
- The study of the ageing of test specimens in high-pressure autoclaves
- Tests under cryogenic conditions for the use of hydrogen in liquid form, with several cryostats fed by a helium-hydrogen liquefier
- Multiphysics tests with pressure, temperature and .... cycling.
- Manufacture of thermoplastic composite parts (tanks, tubes) by in-situ deposition and consolidation (in real time, with no further steps required) using our HySPIDE TP robotized cell.
