The presentation will discuss the usage and benefits of the diagnostic simulator for the development of OTX-based diagnostic sequences on concrete examples.

What the audience will learn

Due to the high natural frequencies of electric motors, it is necessary for the bases of test equipment to be very rigid so that resonance frequencies do not distort the recording of test results. Cast iron and welded steel constructions reach their limits here.

What the audience will learn

• Use of UHPC for test benches
• Design of machine elements with UHPC
• Analyses of machine elements with UHPC

In the context of e-mobility applications trending rapidly toward more and more powerful drive systems, two main issues can be identified regarding appropriate facilities to measure, test and record drive systems: the boundary conditions of installation space for testing of complete e-axles are getting more and more difficult because of the high integration of e-drives; and the integration of measurement technology (torque cells) has to be adopted to high speeds. At a certain point you can either use specific measurement devices or – much easier – use the right couplings. The presentation will show examples of integrated central shaft cooling.

What the audience will learn

• Testing of the most powerful e-drives and e-axles
• Modular test rigs and retrofitting of existing facilities
• Intelligent integration of measurement systems

The value of scenario data in autonomous driving development is vital. The source of traditional scenario data mainly relies on real vehicles recording data. Data costs remain high and scenario coverage is very limited. Now we can use digital twin technology to transform real road data into virtual scenario models and effectively generalize the behavior of traffic participants to achieve exponential growth in scenario data generation. The high-precision data acquisition, digital twin, simulation and back-injection toolchain launched by ZD Automotive could create high-coverage, high-quality data at low cost and facilitate autonomous driving to efficiently close the data loop.

What the audience will learn

• Traditional data limits – reliance on costly real vehicle recordings with limited scenario coverage
• Digital twin and generated reality innovation – transform road data into virtual models, exponentially increasing scenario data
• Efficient data solution – high coverage and quality data at low cost, closing the autonomous driving data loop

The safety and performance of high-voltage components is significantly affected by temperature. In particular, HV batteries are susceptible to temperature effects. Therefore, temperatures have to be monitored extensively alongside high density inside HV components in the development process. The question now is, how can many temperature channels be realized without sacrificing the sealing of components and influencing their overall behavior? In this presentation Dipl.-Ing. Timo Eich discloses a revolutionary approach to precisely measure hundreds of temperatures inside HV components with pin-point accuracy utilizing a single digital, high-end temperature measurement system with a minimally invasive character.

What the audience will learn

• Why classical instrumentation with thermocouples or RTDs fails when lots of measurement points are demanded inside of HV components
