The presentation will introduce the targeted design of the climate test chamber in the automotive inspection field, covering the design and manufacturing standards of the test chamber, the required test methods, and the acceptance calibration method. Combined with the technical innovation and some application examples of Chongqing Harding Environmental Testing Technology's products, the presentation will share the safety-conscious and energy-saving design of the new energy vehicle application test box.

Due to the electrification megatrend, EV components with high-power behavior are becoming increasingly popular. At the same time, the requirements of HIL testbeds are gradually transitioning from signal level to power level. The Power HIL solution is aimed at battery modules and packs, BMS, OBC, DC-DC and e-drive systems. While importing the vehicle simulation model, this testbed can not only implement signal control and test but also include real high-power input and output function. In comparison with traditional signal-level HIL systems, the power-level HIL testbed can cover the whole function of high-power EV parts and support to meet the ISO 26262 HIL-related test requirements to help achieve ASIL functional safety certification.

How do you measure temperature directly and safely in motor winding? How do you improve the test efficiency through the digital wireless telemetry torque sensor? How do you test performance on motor test benches? imc data acquisition combines with various advanced measurement technologies to provide a powerful measurement platform tool for electric vehicles, and provides measurement completion solutions from sensors to analysis and test reports.

The presentation will cover the significance and procedure of the concept study, critical elements and the benefits of turnkey solutions.

The presentation will outline the advantages of virtual development and IPG Automotive as a solution provider. It will also give an overview of CarMaker and show a full software stack integration, photorealistic environment, a sensor simulation portfolio, scenario generation/importing, integration interfaces, HIL test systems, HPC and cloud application and a virtual prototype.

In 1979, framag was founded as a subsidiary of Len-zing AG. In addition to mechanical engineering, the company – which is based in Upper Austria – lists vibration technology among its core competences. Vibration technology from framag is used not only in the machine tool industry but also in test bench construction. The test bench technology division at framag engineers and manufactures test benches to customer requirements, which are technically superior to conventional test benches thanks to their specialist properties. Base frames, clamping plates, intermediate frames etc. are supplied to well-known customers for test bench construction. Thanks to its use of the composite material HYDROPOL, framag is at the cutting edge of technology in this field.

In this presentation, you will learn about capturing, ingesting, tracking and reprocessing petabytes of test data using the EB Assist toolchain for ECU function validation. Accelerate development with one tool that supports data generation, labeling, data discovery and test execution. Get insights into how subsequent automated upload to our EB Assist Test Lab data management tool and subsequent download to the HIL machine and replay of the data. The toolchain includes the latest technology to conduct sensor-model-based capturing of data, replaying data and bus simulation to emulate a full automotive rest bus to the device under test, validating ECU functions in the most efficient manner.

Accelerometer sensors are widely used in vibration testing at various humidity and/or temperature-controlled environments, for example in vibration shaker testing, modal analysis, NVH at room temperature, and powertrain performance up to 1000°C. This presentation will review the principle of piezoelectric material and accelerometer, the selection tips of accelerometers in different applications and demonstrate why accelerometer designs (e.g. DJB’s unique KONIC Shear®) are important to testing quality. The future developments of piezoelectric accelerometers to meet extreme temperature testing environments will also be reviewed and the associated challenges discussed.

The presentation will discuss what the EPU/EAS is and what the advantage is in comparison with traditional test system applications.

With the rapid development of information technology, there is an increasing demand for enterprises to achieve real-time monitoring and data management of remote tests. Windhill has independently developed a set of test fleet management systems that supports MQTT/FTP, communicates with vehicles through CAN/CAN FD, supports importing DBC/A2L/ODX and other databases, and supports CCP/XCP/UDS/OBD and other protocols. It is mainly used for data monitoring and data management of road test vehicles. With the vehicle terminal of wireless transmission, it can realize the functions of vehicle positioning, driving status monitoring, historical track playback, data statistics and analysis. It allows data analysis engineers and test managers who are based in other places to view the collected test data any time, anywhere and in time to find and solve problems quickly.

Hybrid and electric vehicles have a wide variety of possible configurations, often consisting of two or more motors and inverters. These vehicles also have heat, AC, infotainment, steering and other electrical loads that use energy. When trying to understand and improve a vehicle’s total energy usage, it is important to understand when and where the vehicle is using energy so that it can be improved. The large number of electrical loads and accuracy needed for trustworthy measurement are not always simple. This session will explain the background to vehicle energy management, present testing challenges in the lab and review testing solutions to understand a vehicle’s energy flow.

Failures due to fatigue typically generate over sustained periods, and vibration test engineers must determine the longevity of a device in a typical field environment. Vibration test acceleration allows these engineers to evaluate a product after years of service in a fraction of the time. An innovative approach to replicating an end-use environment is to use recorded waveforms. There are several techniques where real-world vibration can be replicated using recorded data. The presenter will discuss several methods of test profile generation from recorded data, including industry standards for random and shock vibration and an innovative approach to sine-on-random testing.
