Rapid battery inspections intensified: Innovative technology performs 1 million checks per second, enhancing aircraft and marine vessel safety
Revolutionary Battery Technology Improves Safety, Efficiency, and Longevity
Dynamic impedance spectroscopy, a groundbreaking innovation developed by Germany's Fraunhofer Institute for Manufacturing Technology and Advanced Materials (IFAM), is set to transform the battery industry. This technology, with potential applications in eco-friendly electric aircraft and the shipping industry, aims to enhance the safety, efficiency, and longevity of batteries used in electric vehicles, renewable energy systems, and future aircraft.
Traditionally, battery monitoring required batteries to be at rest for up to 20 minutes to deliver state information. However, the new real-time measurement technique performs dynamically, during live operation. It overlays a multi-frequency test signal on the battery current during charging or discharging and captures data up to one million times per second. This delivers a detailed and accurate picture of the battery’s state of charge (SoC), state of health (SoH), and internal safety status almost instantaneously.
This continuous, live assessment allows battery management systems to detect early signs of cell degradation or localized overheating and take preventive action, thereby enhancing safety and preventing failures or thermal runaway. It also optimizes battery usage and charging strategies to extend the overall battery lifespan, reducing degradation and prolonging service life. Moreover, it provides more precise and faster information than conventional charge status displays, facilitating improved efficiency in battery operation and management systems.
The innovation makes impedance spectroscopy more powerful, faster, and practical for real-time use during operation. Specialized algorithms developed by the research team reduce the volume of data instantly without compromising accuracy. Dynamic impedance spectroscopy holds promise for renewable energy providers who rely on battery storage to balance fluctuating power inputs, as it allows for more precise real-time monitoring.
The method isn't limited to lithium-ion (Li-ion) batteries; it can also be applied to solid-state, sodium-ion, lithium-sulfur, and future battery technologies. The project was led by Fabio La Mantia, PhD, a professor of energy storage and conversion systems at the University of Bremen.
With this development, battery systems become smarter and more reliable, with better predictive capabilities for maintenance and safer operation under real-world conditions. This supports the advancement of electric mobility, sustainable energy, and next-generation aviation technologies.
