摘要:
Provided herein are approaches for embedding one or more protection components within a substrate, such as a printed circuit board (PCB). In one approach, an apparatus includes a first PCB layer and a second PCB layer, and a plurality of protection components formed between the first and second PCB layers. The apparatus further includes a core housing encasing the plurality of protection components, and a set of encapsulation layers formed over first and second sides of the core housing. In some approaches, the plurality of protection components are selected from the group consisting of: fuses, positive temperature coefficient devices, integrated circuits, and/or sensors. Electronic components, such as resistors and capacitors may be surface mounted on the top side of PCB to complete the protection circuit with the protection components. Through terminal connection, reflow soldering or other approaches, the apparatus may be connected to a battery pack to protect battery operation.

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.
