The electrification of the drive train for cars or commercial vehicles has further increased the complexity of recording data on the test bench. A large number of different signals and measured variables must be recorded and analyzed. Moreover energy efficiency is also of crucial importance in other areas where it is often regulated and must be proven by compliance standards.
There is a variety of drive topologies for modern e-vehicles. With one machine, with front and rear machine or also with four drives close- or in-wheel. A large number of measured variables must be recorded.
The drive system of a train is electric. Here, too, are different topologies that are used depending on the application.
The programming of wind inverters via the "power curve" (also called U/P characteristic) cannot work without the performance measurement. Depending on the generator and the location, a suitable "power curve" must be programmed.
Energy systems that are fed by solar panels have an inverter that converts DC voltage into AC voltage suitable for the grid. The efficiency plays the decisive role here. The measurement of the so-called "power conditioning system" is done with the help of a precise performance measurement system.
The electrical efficiency is an important parameter for every electrical consumer. For this reason, the applications are almost unlimited. Wherever voltage and current are used, performance measurement is of great importance.
