BDL Next – Next generation bidirectional charging

BDL-next aspires to bring bidirectional charging to mass market readiness, overcoming technical, legal, and procedural hurdles. The initiative builds on the BDL project, which highlighted the multifaceted capabilities of electric vehicles for energy markets, grid support, system services, and user benefits. Essential to this is the smart management of power as seen in self-consumption optimization for solar setups and grid frequency regulation. Currently, technological, legal-regulatory, and procedural gaps still prevent the seamless transition to mass real-world operation of bidirectional charging strategies.

This is precisely where BDL Next begins: The project aims at simplifying and enhancing the technology of bidirectional charging to fit seamlessly into the current energy market and service systems. Work is also being done on the grid-oriented and market-oriented operation of bidirectional vehicles, so that they may become an integral part of our robust and intelligent power grid. A multi-stage field trial will use real-world experiences to identify weaknesses in the concept and technical development, further increase the economic and ecological benefits of bidirectional charging, and simplify the integration of the technology from a customer perspective.

The main tasks of our chair include:

  • Analysis of Vehicle-2-Grid cross-border effects.
  • Analysis of Vehicle-2-Grid related wholesale market price effects.
  • Development of MobiFlex model to estimate V2G flexibility based on new mobility data
