SAFETY SENSOR MODULE WITH VEHICLE COMMUNICATION TO FIRST RESPONDERS
A battery system for a vehicle includes a battery pack having a structure defining a chamber receiving a battery. A first sensor is mounted to the structure for sensing an operating condition within the chamber. A safety module is disposed outside of the chamber. The safety module processes signals received from the first sensor to identify if the operating condition defines an abnormal condition occurring within the chamber. The safety module sends a first safety module signal when the signals received from the first sensor indicate the abnormal condition is present within the chamber.
1 . A battery system for a vehicle, comprising:
a battery pack having a structure defining a chamber receiving a battery;
a first sensor mounted to the structure for sensing an operating condition within the chamber; and
a safety module disposed outside of the chamber, the safety module processing signals received from the first sensor to identify if the operating condition defines an abnormal condition occurring within the chamber, the safety module sending a first safety module signal when the signals received from the first sensor indicate the abnormal condition is present within the chamber.
2 . The battery system for a vehicle of claim 1 , wherein the structure includes a frame having an outer wall defining a portion of the chamber, and the first sensor is attached to the outer wall.
3 . The battery system for a vehicle of claim 2 , wherein the first sensor is a smoke sensor mounted to the outer wall.
4 . The battery system for a vehicle of claim 2 , wherein the first sensor is gas sensor mounted to the structure.
5 . The battery system for a vehicle of claim 2 , wherein the outer wall is attached to a vehicle.
6 . The battery system for a vehicle of claim 1 , wherein the structure includes a bottom wall and the first sensor defines a moisture sensor positioned on the bottom wall.
7 . The battery system for a vehicle of claim 6 , wherein the bottom wall includes a low point, with the moisture sensor positioned at the low point.
8 . The battery system for a vehicle of claim 1 , wherein:
the battery includes multiple battery cells,
the structure includes a cross beam defining a plurality of sub-chambers each receiving at least one of the multiple battery cells, and
the first sensor defines multiple identical sensors having individual ones of the multiple identical sensors mounted in each of the sub-chambers.
9 . The battery system for a vehicle of claim 1 , further including a second sensor mounted within the chamber detecting an operating condition within the chamber different from the operating condition sensed by the first sensor, the safety module sending a second safety module signal when the signals received from the second sensor define abnormal conditions present within the chamber.
10 . The battery system for a vehicle of claim 9 , further including a third sensor mounted outside of the chamber detecting a condition of the structure, the safety module processing signals from the third sensor to identify if an abnormal condition of the structure is present.
11 . The battery system for a vehicle of claim 10 , wherein the third sensor is included with the safety module.
12 . The battery system for a vehicle of claim 2 , wherein the safety module is mounted to the outer wall.
13 . A battery system for a vehicle, comprising:
a battery pack having a structure defining a chamber receiving a battery;
a first sensor mounted to the structure sensing conditions of the structure; and
a safety module disposed outside of the chamber, the safety module processing signals received from the first sensor, the safety module sending a safety module signal when the signals received from the first sensor indicate an abnormal condition of the structure.
14 . The battery system for a vehicle of claim 13 , wherein the first sensor defines an accelerometer mounted to the structure.
15 . The battery system for a vehicle of claim 13 , wherein the first sensor defines a strain sensor mounted to the structure.
