Vehicle Testing

Starting with consulting and system procurement, we take over the entire project management. We install the measurement technology, including cabling and the complete application of sensors and actuators. Configuration and data evaluation are just as much part of the scope of services as calibration, functional testing and subsequent dismantling of the test vehicles. A modern technology center and an experienced team of application engineers and mechanics are available specifically for this purpose. In the course of the steadily growing importance of hybrid systems and electric vehicles, we have developed our own high-voltage hardware solutions for current, voltage and temperature. These allow all relevant measured variables to be recorded via IPEmotion or our CAN bus data logger. They can also be integrated into existing CAN bus systems. In the context of the development of hybrid systems and electric vehicles, these are becoming increasingly important. Thanks to TÜV certification of our HV measurement technology as well as continuous further education and regular training in the high-voltage field, we guarantee the highest level of quality and safety. A separate area is available for the safe upgrade of electric and hybrid vehicles.

Thermal management is a key topic in vehicle development that is taken into account in the development process right from the start. Valuable development steps can be taken at an early stage on a TC5:E5hermomanagement system test bench. By integrating calculation models and simulators/emulators, qualitative statements on systems, components and control strategies for cooling, heating and refrigeration circuits could be made at an early stage of development (without a vehicle). In addition, early testing of operating strategies is possible. In further phases of development (including series production support), problems can be reproduced and causes investigated in a reproducible environment.

In the early development phase of the electric refrigerant compressor, a variety of assurances for durability, efficiency and performance are necessary even before the actual design and process validation tests. For this purpose, there are test cases that require flexibility in their requirements and mapping while maintaining high quality standards. Here, IPEengineering's experience in handling such complex setups is unique in the service field. Through a strong team of engineers and technicians who have built up years of experience in the evolution of refrigerant compressors, the development accompanying tests from the start of development to the finished product provide a complete package in the service sector of the automotive industry.

As a reliable partner with many years of experience, we offer all-round service in the field of vehicle testing. Our core competencies lie in the successful organization of vehicle and endurance tests. This includes planning, execution and analysis. In addition to testing under extreme conditions, we also carry out tests on individual components. In doing so, we always act according to our core values of efficiency, quality, adherence to schedules, flexibility and customer orientation. This enables us to meet even the most demanding requirements.

IPETRONIK offers its customers innovative options for the pre-development of refrigeration and coolant circuits, combining the advantageous features of a test bench setup with the flexibility of vehicle measurements: We build customer-specific vehicle subsystems in a vehicle body with extensive measurement technology. This allows system characteristics of new bodies to be experienced directly in the passenger compartment during measurement operation, which otherwise (as usual) only have to be interpreted on the basis of test bench measurement data. In addition, development carrier vehicles of this type can also undergo measurements in the climatic wind tunnel, on test tracks or in stationary operation. Our prototype workshop enables concepts to be realized at an early stage of development, when only a few components are available.

In the context of application and measurement tasks, it is sometimes necessary to design and manufacture special hardware solutions. In addition to experienced employees, a comprehensive range of machinery is available for this purpose.

In our strain gauge laboratory we apply any kind of components. By means of strain gauges, we record a wide variety of parameters. With the information gained from this, we can make targeted changes to prevent material fatigue, for example. We also advise on the optimum positioning and calibrate the strain gauges and the complete measurement chain. Special torque applications including telemetry are also part of our services.

We have the competence to support your component or system in the development process from early concepts to series production and beyond. Together with our partner ARRK Engineering, we can map the complete product development process. From design and simulation to testing and validation.

The measurement of thermodynamic properties of refrigerant circuit components is of great importance in the development of automotive components (and systems). Our measurement results are often used as a basis for decision-making for series production as well as for the analysis of optimization potentials or unique selling propositions. As a manufacturer- independent test center with many years of cross- industry experience in the field of thermodynamics, IPETRONIK offers component measurements including well-founded evaluations. OEMs and Tier 1 suppliers as well as development partners benefit from our services.

In the modern development of vehicle air conditioning and in connection with thermal management, the technical design or the validation of the function of the refrigerant compressor is the focus of the holistic development process. Especially due to the changing requirements in the automotive sector, it is indispensable to reproduce a flawless function of the test item to be tested by means of reliable test bench equipment. Be it in the classic AC mode or in the now increasingly important heat pump mode. The interaction of sustainable hardware in the test bench and the coordinated control in the form of the in-house software IPEmotion make this test bench a unique product in the service sector of the automotive industry.

The climate-acoustic chamber with its flexible conditioning from cold to heat climate offers ideal boundary conditions to realistically load the heating/air conditioning system of a vehicle. With the control of the temperature from -20°C to +50°, the humidity, the sun simulation by means of infrared lamps as well as the vehicle inflow with up to 32 km/h driving wind, a variety of climate zones can be simulated as vehicle environment. In addition to the thermodynamic usability, the design as an acoustic semi-free-field room together with the hydrophobic attenuation of all conditioning components allows the authentic evaluation and measurement of acoustic phenomena. Typical applications include the testing and subjective evaluation of in-vehicle air conditioning compressors, HVAC noise (evaporator hiss) and general transfer path analysis of the refrigeration circuit.
