Abstract
The present invention extends to methods, systems, devices, apparatus, and computer program products for detecting battery status and failure. In general, detecting mechanical swelling of a battery cell along with optional measurement of temperature increases can be used to identify a battery cell as failing or failed. Force strain sensors or similar extension/compression sensors can be mounted in a (e.g., fire resistant) sleeve surround a battery pack and/or between cells in a battery pack. In some embodiments, extension/compression sensors are used along with temperature probes to detect battery cell failure.
