POUCH CONTAINMENT SYSTEM FOR THERMAL PROTECTION USING SENSOR INTEGRATION AND EMERGENCY RESPONSE TRIGGERS

1 . A battery system, comprising:

at least one sealed chamber disposed between a plurality of battery cells; and

at least one sensor configured to detect a physical condition of the sealed chamber and trigger a response, wherein:

the sealed chamber is configured to mechanically deform when subjected to mechanical force resulting from swelling of an adjacent battery cell, and

the sensor is configured to detect mechanical strain or expansion of the sealed chamber associated with swelling of the adjacent battery cell.

2 . The system of claim 1 , wherein the sensor is a pressure sensor detecting inflation of the at least one sealed chamber.

3 . The system of claim 1 , wherein the sensor is a thermocouple affixed to a conductive metal surface.

4 . The system of claim 1 , wherein the response comprises notifying a vehicle operator and initiating a controlled shutdown.

5 . The system of claim 1 , wherein the at least one sealed chamber is filled with a pressure-reactive material and the sensor detects mechanical strain at a welded seam of the sealed chamber.

6 . The system of claim 1 , wherein the sensor is configured to detect an early-stage battery venting and signal a preemptive cooling prior to a thermal runaway condition.

7 . The system of claim 1 , wherein the system comprises logging of a thermal event.

8 . The system of claim 1 , wherein the at least one sealed chamber is formed from welded metal sheets and the sensor is embedded at the weld seams.

9 . The system of claim 1 , wherein the at least one sealed chamber and the sensor are positioned between adjacent battery cells within a battery module.

10 . The system of claim 1 , wherein the sensor comprises self-diagnostic capabilities.
