Project Bidirectional Charging Management—Insights and Evaluation of the Field Trial

The research project “Bidirectional Charging Management” (BCM) tests bidirectional charging applications in a comprehensive field trial to demonstrate the customer benefits and value of this technology. Various data are collected for the evaluation of the field trial and the assessment of the different use cases. This study gives an overview of first results while focusing on the private customers. The functionality of the increase of self-consumption use case is described and key values are presented. Due to the delayed start of the field trial, only the unfavorable winter months with less solar radiation could be analyzed so far. Nevertheless, the data show that customers with a large PV system, high household power consumption and connection time during the night as well as a low target State of Charge (SoC) reach the best results in this use case. Furthermore, the own consumption rate and self-sufficiency are compared to different charging methods and the efficiency of the system is evaluated.
