Abstract
A vehicle battery safety sensor system providing liquid detection inside a battery pack includes a battery pack having a structure defining a battery cell bay receiving a battery. A first sensor is mounted to the structure proximate to a low point area of the battery cell bay for sensing an operating condition within the low point area of the battery cell bay. A second sensor is mounted to the structure elevated above the first sensor for sensing an operating condition above the low point area of the battery cell bay. A safety module processes signals received from the first sensor and the second sensor and identifies if the operating condition within the low point area of the battery cell bay defines a fluid present in the low point area of the battery cell bay.
