POUCH CONTAINMENT SYSTEM FOR THERMAL PROTECTION USING SENSOR INTEGRATION AND EMERGENCY RESPONSE TRIGGERS
This disclosure describes a battery device with at least two battery cells and a stainless-steel foil pouch located between the battery cells. The stainless-steel foil pouch holds a liquid and/or chemicals that prevent and/or delay thermal propagation. The battery device integrates sensors and emergency response triggers.
1 - 10 . (canceled)
11 . A method, comprising:
placing at least one sealed chamber between a plurality of battery cells;
detecting a physical condition of the sealed chamber via at least one sensor; and
triggering a response according to the detected physical condition.
12 . The method of claim 11 , wherein the sensor is a pressure sensor detecting inflation of the at least one sealed chamber.
13 . The method of claim 11 , wherein the sensor is a thermocouple affixed to a conductive metal surface.
14 . The method of claim 11 , wherein triggering the response comprises notifying a vehicle operator and initiating a controlled shutdown.
15 . The method of claim 11 , wherein the at least one sealed chamber is filled with a pressure-reactive material and the sensor detects mechanical strain.
16 . The method of claim 11 , wherein the sensor is configured to detect an early-stage battery venting and signal a preemptive cooling.
17 . The method of claim 11 , wherein the method comprises logging a thermal event.
18 . The method of claim 11 , wherein the at least one sealed chamber is formed from welded metal sheets and the sensor is embedded at the weld seams.
19 . The method of claim 11 , wherein the at least one sealed chamber and the sensor are configured together for retrofitting into existing battery modules or packs.
20 . The method of claim 11 , wherein the sensor comprises self-diagnostic capabilities.
