This study shows a novel online approach for characterizing battery cells or modules in any type of reconfigurable battery system (RBS) for electric driving applications, which allows neighboring cells or modules to switch in parallel. Also, the different representations (time and frequency domain) of conventional battery modeling based on equivale...

... the generated information is characterized with simple second order ECM. Figure 5 shows the slight reduction in fitting accuracy, namely increasing the relative error from 2 × 10 − 7 to 5 × 10 − 5, but the behavior of the cell is still modeled to a large extent. As expected, the estimated dynamic parameters are not the same as for the tuned model, since the behavior of three RC is modeled by two RC. ...

Conference Paper
The electrification of the transport sector is crucial to achieve the environmental goals. The application of Internet of Things (IoT) and Cloud Computing can be part of the solution for improving efficiency and fault detection, and increasing the driving range for electric vehicles. The growing data generation and new data analysis methods demand high computing power and data storage capabilities. By combining IoT devices with Cloud Computing, the condition of a vehicle can be monitored in real time from anywhere in the world. In this paper, a new cloud architecture for the analysis of stationary and mobile measurements is presented. Additionally, a web application is developed for a detailed visualization and analysis of historical and real time data.
