Abstract: A leak detection system for a battery enclosure for one of a rechargeable energy storage system, a battery cell, a battery module, and/or a battery pack includes a gas delivery system configured to selectively provide a trace gas to the battery enclosure. A first optical gas imaging sensor is configured to generate images of a surface of the battery enclosure after the gas delivery system charges the battery enclosure with trace gas. The images are used to selectively detect a gas cloud adjacent to the surface of the of the battery enclosure. The gas cloud is used to determine a location of a gas leak on the surface of the battery enclosure.
