Abstract
A fire suppressant for cooling a battery pack includes a pressurized mixture of a dry chemical and carbon dioxide. The dry chemical is an inorganic particulate chemical. The dry chemical particles are small enough to be carried by a flow of depressurizing carbon dioxide. A mass of the dry chemical is between 5% and 50% of a mass of the carbon dioxide. The carbon dioxide, when depressurized, vaporizes and cools the dry chemical and the battery pack. The dry chemical can adhere to the battery pack when the mixture is depressurized. An amount of the fire suppressant used to cool the battery pack is equal to or greater than an inerting volume of fire suppressant for the battery pack.
