Projektbeschreibung

The goal of the project is to develop a fully networked battery management system (BMS) for electric vehicles that improves range predictions and extends battery lifespan. 

The project is funded by the German Federal Ministry of Transport (BMV) with a total of 2 million € as part of the mFUND innovation initiative. To implement the project, the associated project partner, SOL Motors GmbH, is providing its innovative small motorcycles as examples. 

Intelligent Networking of Battery and Energy Management

At the outset, extensive data will be collected at the test benches of the Karlsruhe Institute of Technology (KIT) and at ANSMANN in Assamstadt for the training of AI-based battery models. The actual BMS will be developed by ANSMANN and subsequently linked to the state-of-charge estimation software developed by KIT.

A special feature of DiEMS is the close integration of the BMS with an intelligent energy management system (i-EMS). The vehicle models from Fraunhofer ICT, combined with route planning and other data such as weather forecasts, enable particularly precise range prediction. EnQS GmbH is responsible for the software architecture and the integration of the various components. Simultaneously, a user-friendly interface is being developed to address individual user needs.

The components – from charge level monitoring to range estimation – are initially tested in simulations and on test benches before being combined into a complete system. Finally, the system is installed in a SOL Motors moped and tested under real-world conditions.

About the BMV's mFUND:

As part of the mFUND innovation initiative, the BMV (Federal Ministry of Transport) supports data-driven research and development projects for the digital and connected mobility of the future. Project funding is complemented by active professional networking between stakeholders from politics, business, administration, and research, and by the provision of open data on the Mobilithek (Mobility Library).
