<p>PURPOSE:To provide battery performance independent of outside humidity via the control of battery operation humidity, and avoid an ignition accident without exposing a battery directly to the atmosphere, even if a battery housing container is broken, by connecting a heat exchanger to a battery device and covering the outer wall of the device with an insulation material. CONSTITUTION:A cell 1 with the side and bottom covered with a nonaqueous cooling medium 7, is housed a battery housing container 8. While external positive and negative terminals 10 and 11 are being led out, the cell 1 is secured with a battery fastener 9, and the upper side of the cell 1 is concealed with a cover having a vent valve 12. The end of a humidity measurement instrument 13 is inserted in a cooling medium located along the periphery of the container 8, and the container 8 is provided with a heat exchanger 16 for supplying secondary feed water 17. Also, a pump controller 18 is operated, according to the temperature indicated with the instrument 13, and the feed water 17 is circulated through the medium 8 on the operation of a pump 15 connected to the heat exchanger 16. Furthermore, the outer wall of the container 8 is covered with an insulation material not shown herein. According to this construction, a high- output type nonaqueous electrolytic secondary battery can be efficiently cooled.</p> |
