HV measurement for traction batteries, acoustic dummy head from Ipetronik
At the upcoming Sensor+Test trade fair (Nuremberg, Germany, May 30 to June1), automotive measurement technology expert Ipetronik GmbH will showcase a range of products for R&D engineers in this industry. The spectrum ranges from a customized measuring system for safe HV measurement in electric and hybrid vehicles to a dummy head for acoustic and climatic engineering to. With Arcos 1.5, Ipetronik is also exhibiting a modular high-performance data logger system for fleet trials.
HVshunt2 is a measurement system for safe HV measurement in fleet trials of electric and hybrid vehicles. Recording of voltages, currents and temperatures in the HV environment of vehicle batteries is a key measurement application. With the new HVshunt2 as a further development of the established HVshunt, the measuring range for current measurement up to +/-900 A has been extended via a current transformer with an accuracy of +/-0.2 %. Thanks to the pre-assembled customer-specific cables with HV connectors, the module facilitates tool less and safe integration into the HV on-board power supply, which in turn permits short periods for the instrumentation and disassembling of the test vehicle.
With the development of the IPEacoustic head, Ipetronik is extending its expertise in the field of vehicle climatic/acoustic engineering. This innovative dummy head, which has a wedge-shaped design, features a binaural microphone arrangement for aurally compensated noise recording as well as a third microphone in an acoustically neutral measuring position. Half-inch microphones with IEPE or 200V power supply are used. The IPEacoustic head allows climatic/acoustic tests to be conducted reproducibly in the vehicle with identical installation positions. The head provides space inside its torso for a noiseless PC for online measurement data processing with IPEmotion. The dummy head is compatible with standard acoustic measuring systems.

The Arcos 1.5 data logger system, with features like a modular concept, high processing power, data storage capacity and reliability, suits for demanding tasks in vehicle fleet trials. The modular system architecture offers users a high degree of flexibility and investment protection, since the logger can be adapted according to the particular measurement task. Thanks to the modular design with plug-in modules, it is possible to extend the number of bus interfaces for CAN, CAN FD, LIN, FlexRay, ETH, MOST according to the demand. In addition, the system logs large on-board power supply topologies with numerous bus networks and control units using the most important protocols such as CCP and XCP.

Test drives which for example require validation by assistance systems or aim at recording the behavior and field of vision of the driver can be implemented using multiple USB cameras and up to eight IP cameras. The data are stored on CF cards and via SATA interfaces with a large memory depth of up to 1 TB in Raid 10. The wireless communication is implemented via a plug-in module with globally operating 3G modems, GPS, Glonass and Baidu position data acquisition and modular W-LAN modules. The absolute special feature of the Arcos 1.5 hardware platform is the option of switching over the operating mode. For logger operation, Linux normally runs on the device as an operating system. Alternatively, it is possible – by swapping the removable storage medium – to operate the same hardware as Windows logger with the IPEmotion software as the application system for control units.
