The first to hear trouble coming
AcouBatt detects acoustic warning signs of potential internal cell failure earlier than conventional monitoring, giving teams more time to investigate, isolate risk and intervene before issues escalate.
What Exactly We Monitor.
Gas Evolution
Detect abnormal internal gas evolution as it develops, providing early warning of emerging cell issues.
Mechanical Damage
Identify acoustic signatures associated with micro-cracking and delamination before they escalate into more serious cell failure.
Cell Degradation
Monitor structural degradation in real time and identify cells trending towards low state of health or early failure.
Why Acoustics Warns Earlier.
Traditional BMS relies on changes in voltage, current and temperature, which may only become clear once failure has progressed. Off-gas sensing adds another valuable layer, but only detects gases once they have reached the sensor. AcouBatt detects acoustic activity generated by internal gas evolution, cracking and mechanical stress as these processes develop inside the cell. This can provide a significantly earlier warning window, giving teams more time to investigate, isolate and intervene before issues escalate. Continuous monitoring also identifies abnormal degradation trends, supporting preventative maintenance and reducing asset risk.
- Earlier warning of emerging safety-critical events
- More time to investigate and intervene
- Supports preventative maintenance and lower asset risk
How It Works In Practice
Sense
External sensors continuously record acoustic activity from your battery modules without modifying the cells or interrupting operation.
Analyse
Our AI analyses and classifies signals in real time, distinguishing normal behaviour from acoustic warning signs of gas evolution, mechanical damage and abnormal degradation.
Alert
When abnormal activity is detected, the affected cell or module is flagged, giving teams more time to inspect, isolate and intervene before the issue becomes safety-critical.
Lead time varies by battery chemistry, cell design, failure mechanism and operating conditions. In our testing, AcouBatt has detected acoustic warning signs hours before clear deviations appear in voltage, current or temperature.
Yes. AcouBatt monitors physical processes common across battery chemistries, including gas evolution, cracking and mechanical degradation. The system is calibrated for each chemistry and cell design.
Yes. AcouBatt can be applied to pouch, cylindrical and prismatic cells, with the sensor configuration tailored to the cell format, module design and operating environment.
Our AI is trained on one of the world’s largest databases of battery acoustic data and validated using labelled battery experiments. Under validated test conditions, our models classify acoustic signals with over 90% confidence.
