DEVELOPMENT OF FLAME PREVENTION DEVICES FOR NICKEL IRON BATTERY MODULES FOR ELECTRIC VEHICLE USE

The effort described in this report consisted of an evaluation of several prototypical components of an electric vehicle battery pack and its safety devices, a critical review of the public technical and patent literature pertaining to combustible gas management, and an experimental evaluation of the best candidate approaches. Three approaches were selected for evaluation: explosion attenuation, hydraulic arresters (water traps), and mechanical module isolation. The major system constraints under which an approach would have to operate were defined as follows: a cost of less than $10 per module, compatibility with common manifold for watering and venting, and stability in caustic and acid electrolytes.
