Battery Simulation with the DC Power Supplies R&S®NGM200 AND R&S®NGU201

This application note is about creating your own battery model for the R&S®NGM200 and R&S®NGU201, beyond the standard models provided within the battery simulation option NGM-K106 and NGU-K106. To get to a battery model, a few steps are required. To determine the parameters for the battery model, it is necessary to discharge a battery using a selected method, to record the data and to calculate the model on this basis. With this software, a connection can be established to the instrument, batteries can be measured using various measurement methods, and a model can then be created from these measurements. These models, which are determined from the measurements, can then be simulated with the power supply, thus creating a digital twin of the battery. Using these, test scenarios can be carried out in a safe and reproducible environment.
