EP Ehrler Prüftechnik Engineering GmbH

We are full-service providers in test bench construction. Our focus is on flow, volume flow and mass flow measurement, temperature, pressure & humidity control or measurements of small gaseous quantities as well as high pressure testing. Our calibration laboratory is DAkkS accredited (according to DIN EN ISO / IEC 17025 for volume and mass flow of flowing gases). We also offer factory calibrations of the measured variables temperature, humidity, absolute pressure, differential pressure and relative pressure. A DAkkS application procedure for these parameters has already been applied for. In order to meet the requirements of more complex thermal management in the field of e-mobility, we are working intensively on future topics and developing test bench solutions for battery and hydrogen technologies. The temperature control of the battery and power electronics plays an important role here, in particular the air conditioning and cooling in electric vehicles. The coolant and refrigerant-based cycle for electric vehicles is very complex. In this branch, too, the goal is to simulate the interaction of various components under real operating conditions in order to meet the requirements of tailored test bench measurement technology. Overview of some tests • Environmental simulation & thermal conditioning • Lifetime tests & functional testing • Battery simulation & battery cooling
