In addition to the classic endurance tests, in which the products are tested for their endurance and durability according to customer specifications, we also offer these test scenarios with environmental simulations, such as temperature and humidity, in order to test the products under all possible conditions. We have a wide variety of test systems at our disposal: Dyno test benches, Back-to-back test benches, charging stations and OBC-Charger test benches. Furthermore, we carry out all necessary high-voltage tests in our test laboratory.

Example of an OBC test setup
This on-board charger test setup shows the climate chamber in which the test object is located and the connected conditioning unit, which regulates the temperature and humidity to which the test object is exposed. In addition, the climate chamber is connected to a wallbox and a Dewetron power analyzer, which also contains the source-drain power supply unit. It can be controlled either with PA-Tools or with imc Studio.
Example of a Back-to-Back test setup
In the back-to-back test, the electric machines are tested in coupled operation. These can be controlled by the customer's own inverters or those provided by us. The environmental conditions are regulated here. We also have the option of testing the inverters in the same test environment or in a seperately connected climate chamber. The DUTs can also be temperature-controlled between -30°C and 130°C with conditioning units.
