US Patent 10008752 Safety feature for energy storage device

Disclosed is a technique for detecting a hazardous condition by a conductive layer in an energy storage device. An energy storage device assembly includes a conductive layer configured to cause a change in an electrical parameter in the event of a hazardous condition. A melting point of the conductive layer is lower than a boiling point of a liquid coolant. An electrical sensor is electrically connected to the conductive layer and configured to detect a change in the electrical parameter in the conductive layer. Upon detecting a change in the electrical parameter associated with a hazardous condition, an energy management system suspends operation of the energy storage device.
