Groundbreaking technology enables rapid, frequent battery inspections at the rate of a million times per second for enhanced aviation and maritime safety.
Dynamic Impedance Spectroscopy, a groundbreaking new technology, is set to transform the way we monitor and manage batteries in various industries. This real-time measurement technique allows for the continuous assessment of a battery's state of charge (SoC), state of health (SoH), and internal safety parameters with unprecedented speed and accuracy.
The technology, developed by a dedicated research team, monitors a battery's internal state during live operation, unlike traditional impedance spectroscopy which requires the battery to be at rest. By overlaying a multi-frequency signal onto the battery's charging or discharging current and measuring responses up to one million times per second, Dynamic Impedance Spectroscopy offers a more detailed and accurate picture of what is happening inside the battery cells.
Improved Safety and Efficiency
The real-time monitoring provided by Dynamic Impedance Spectroscopy offers several critical improvements. Enhanced safety is one such benefit. The system can detect issues such as local overheating within individual cells in real time, allowing the battery management system to immediately take actions like reducing power or shutting down problematic cells before failures or fires occur. This is especially important in safety-critical fields such as aviation and maritime sectors, where battery safety standards are stringent.
Increased efficiency is another advantage. Real-time monitoring enables optimized charging strategies that balance between fast charging during short stops and slower charging during longer sessions, minimizing battery wear and avoiding overheating.
Extended Longevity
By continuously tracking the battery’s internal health, cell degradation can be precisely monitored and predicted. This enables battery management systems to better regulate usage and charging practices, thus extending the battery’s lifespan.
Broader Applicability
Dynamic Impedance Spectroscopy is versatile and not limited to lithium-ion batteries; it can also be applied to advanced battery chemistries including solid-state, sodium-ion, and lithium-sulfur. This broad applicability makes the technology promising for industries such as electric aircraft, ships, and renewable energy storage systems, where safe and reliable battery operation is crucial even under variable operational conditions.
Adoption Across Industries
The shipping industry is showing interest in adopting the technology, and it has attracted attention from other safety-critical industries as well. In a press release, Pleteit suggested that the technology could be used in eco-friendly electric aircraft.
In summary, Dynamic Impedance Spectroscopy brings a significant advancement: real-time, ultra-high-frequency internal battery monitoring during operation. This capability allows immediate detection of faults, precise performance optimization, and predictive maintenance—factors that collectively improve safety, efficiency, and longevity across various high-stakes industries.
Technology like data-and-cloud-computing can be used to store and process the vast amounts of real-time data gathered by Dynamic Impedance Spectroscopy, enabling battery manufacturers and operators to analyze trends and make informed decisions about their batteries' performance and maintenance.
By leveraging cloud platforms, advanced analytics, and machine learning algorithms, data-and-cloud-computing can help battery management systems predict and prevent issues before they become critical, thereby improving overall safety, efficiency, and longevity across industries.
