Development of smart charging technologies for the flexibilization of electric fleets

Mobility is vital in the day-to-day operations of many businesses. In order to reduce fuel costs and improve operational efficiency, nowadays, many businesses are opting for e-mobility and adopting electric vehicle (EV) fleets for their mobility needs. Consequently, charging an electric fleet having a large number of EVs overloads the charging infrastructure and can lead to congestion of the local distribution grid, especially during peak load hours.

In the FlexFleet project, smart fleet charging strategies to reduce peak power demand will be developed along with a booking tool to cater to a fleet with the existing charging infrastructure. The developed charging strategies will be validated on a real-life example fleet of around 100 EVs operated by the associate partner RegioNetz. During the validation, smart charging standards such as ISO 15118, and OCPP 2.0 will be implemented in the charging management. The learnings and the results of the project will be shared with third parties by creating detailed action recommendations for smart fleet charging.

In this project, ISEA is mainly responsible for data analysis, development and validation of smart fleet charging strategies and providing recommendations for smart charging. The project will take place in cooperation with the Beijing Institute of Technology, which is carrying out a similar project in China. The results from the two sides will be combined during the steps of the development of smart strategies and the creation of action recommendations.

The FlexFleet project is funded by the Federal Ministry for Digital and Transport (BMDV).
