System & Integration

The Fraunhofer Battery Alliance develops customized battery modules and systems for a wide range of applications. This includes the simulation-based design of the mechanical structure, thermal management, joining technologies and contacting methods. The focus is also on safety concepts, the development of battery management systems (BMS) and algorithms to determine charging and aging. Optimized charging and operational management strategies, as well as integrated sensors to monitor operating parameters, contribute to increasing system reliability, operational stability and safety. In addition, housings and mountings are optimized and the interfaces of modular battery systems are designed to enable application-specific integration in terms of both performance and communication.

• Prototype development and manufacturing: module and pack development, battery system design, battery housing
• Safety-oriented design of battery systems
• Functional safety and pre-certification of hardware and software components
• Battery management systems (BMS), monitoring, cell balancing, remote diagnostics and cloud-based data management
• Thermal system optimization and management (cooling/ heating)
• Wired or wireless integrated sensors
• Battery state estimation algorithms (SOx)
