Abstract
A battery safety system includes a flow valve and a sensing device. The flow valve is disposed on a housing of the battery and includes a first valve that is embedded inside the housing and a second valve that intersects the housing. The first valve includes a cavity through which analytes released upon electrochemical reactions within the battery flow towards the second valve. The second valve extends through the housing to the outside, and defines an opening through which the released analytes exit the housing. The sensing device is disposed within the cavity of the first valve of the valve and is situated in a manner to be in fluidic contact with the released analytes as they flow from the inside of the battery to the outside. In some aspects, the battery safety system can detect a minute presence of one or more analytes. In some aspects, the sensor is in communication with a battery management system.
