Battery apparatus and method for detecting thermal runaway of vehicle battery

Abstract

A battery apparatus for a vehicle of the present disclosure includes a battery module including a plurality of battery cells having a battery cell, a surface of which includes powder coated thereon, a cooling path which is positioned under the battery module and into which a gas generated from the powder is introduced when the surface of the batter cell reaches a specific temperature, an outlet duct which is connected to the cooling path and discharges the gas introduced from the cooling path to an outside through an outlet port, a gas sensor which is installed in the outlet duct and detects the gas introduced into the outlet duct to generate a gas detection result, a vehicle controller which receives the gas detection result and processes the gas detection result into information indicating a possibility of thermal runaway of the battery cell, and a peripheral device which receives the processed information and outputs the possibility of the thermal runaway of the battery cell as visual information or auditory information.
