Fraunhofer R&D Center for Electromobility Bavaria PHOENIX - Building more reliable and performant batteries by embedding sensors and self-healing functionalities to detect degradation and repair damage via advanced battery management system
Developing more efficient and reliable batteries
The PHOENIX project focuses on researching self-healing, sensor, and trigger functions in batteries. By developing cells that can last longer and identify and prevent various types of degradation, the goal is to enhance the sustainability and cost-effectiveness of batteries.
With the implementation of an advanced battery management system (BMS), it will be possible to identify performance degradations and evaluate the overall battery quality. This approach could potentially extend the service life of batteries by up to 100%.
Fraunhofer ISC plays a crucial role in developing the sensors and trigger functions. These sensors are designed to detect degradation within the cell. Expansion, temperature, and ultrasonic sensors are being assessed for this purpose, while mechanical, thermal, and magnetic triggers are being explored to initiate the self-healing process within the battery materials.
