<P>PROBLEM TO BE SOLVED: To greatly improve safety in an abnormal condition by surely preventing nonaqueous electrolyte batteries from becoming abnormally high temperatures to be fired while efficiently cooling the nonaqueous electrolyte batteries. <P>SOLUTION: The power supply device comprises the plurality of chargeable nonaqueous electrolyte batteries stored in an exterior case 2. Herein, fire extinguishing chemical 3 is filled in the exterior case 2, and the nonaqueous electrolyte batteries 1 are immersed in the fire extinguishing chemical 3 and cooled via the fire extinguishing chemical 3. The nonaqueous electrolyte batteries immersed in the fire extinguishing chemical are cooled in an ideal condition to reduce their temperature rise. This surely prevents the nonaqueous electrolyte batteries from becoming abnormally high temperatures to be fired. When the nonaqueous electrolyte batteries become the abnormally high temperatures to release high temperature gas, the gas is released into the fire extinguishing chemical, thereby surely preventing cooling liquid from catching fire from the gas as well as firing the outside resulting therefrom. <P>COPYRIGHT: (C)2009,JPO&INPIT |
