Patent ID: 8211559

Claim:
A leak detection system comprising: a first structure adapted to contain a liquid or a liquid storage structure used in an energy storage system, said first structure further comprising an electrical terminal section that extends through said first structure; a second structure placed in proximity to a surface of said first structure; a first conductor coupled to a first area of said second structure; and a sensing system adapted to sense a change in at least one electrical value or measurement associated with a leak state electrical path that includes at least one area of said second structure and said liquid in an interior portion of said first structure, said sensing system is coupled to said first conductor and said electrical terminal section; wherein said second structure is adapted such that said electrical value or measurement will change when at least some of said liquid comes in contact with said second structure; wherein said leak state electrical path comprises an electrical path between said electrical terminal section and said liquid which is completed when a breach occurs in a portion of said first structure which permits said liquid to pass through said first structure.
