<p><P>PROBLEM TO BE SOLVED: To provide a technique for a battery pack or the like, capable of preventing capacity deterioration due to heat from an electronic device body. <P>SOLUTION: The battery pack 40 includes a first casing 41 containing battery cells 43a-43d and a second casing 42 containing battery cells 43e-43h. The first casing 41 can be fitted to a recessed part 26 to which a normal battery pack can be fitted, the recessed part 26 being provided on the bottom surface side of a notebook PC body 10. The second casing 42 is provided with an inclination of a predetermined angle relative to the first casing 41 so as to extend backwardly from the rear end side in the bottom surface of the first casing 41. Since a clearance can be formed between the bottom surface of the notebook PC body and the upper surface of the second casing, the heat from the PC body 10 can be prevented from reaching the inside of the second casing 42. Thus, the capacity deterioration of the battery cells 43a-43h can be prevented. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
