Embodiment Construction

[0031] Next, embodiments of the present invention will be described with reference to the drawings. Figure 1 to Figure 6 The battery pack accommodates the battery pack 9 in the exterior case 2 . The battery pack 9 connects a plurality of rechargeable batteries 1 in series and in parallel through the guide plate 3 .

[0032] [Exterior case]

[0033] figure 2 , image 3 and Image 6 The illustrated exterior case 2 has a box shape having a heat dissipation case portion 10 for dissipating heat from the battery 1 on the opposing surface, and accommodates the battery pack 9 inside. Although the exterior case 2 in the drawings is provided with the heat dissipation case portion 10 on two opposing surfaces, the exterior case may also be provided with the heat dissipation case portion only on one of the opposite surfaces. The exterior case 2 in the drawing has a shape in which the outer shape of the heat dissipation case part 10 is a square, and the periphery of the square is con...

Abstract

The invention discloses a battery pack. A battery combination (9) connected with terminal electrodes (1A) of a plurality of batteries is accommodated in an external shell (2) through a guide plate (3); each battery (1) is accommodated in the external shell (2) under the condition that the inner faces of a heat dissipation shell (10) on at least one opposite side is opposite to the terminal electrode (1A); the guide plate (3) connected on the terminal electrode (1A) of the battery (1) is thermally coupled to the inner face of the heat dissipation shell (10) by the battery pack; the external shell (2) is made of plastics; an inner-face protruding part (12) thermally coupled with the guide plate (3) in a face contacted state is arranged on the inner face of the heat dissipation shell part (10) in a protruding manner; a concave part (13) is arranged outside the inner-face protruding part (12) by the heat dissipation part (10); and the heat of the battery (1) is conducted to the inner-face protruding part (12) of the heat dissipation shell part (10) from the guide plate (3), so as to emit heat to outside from the external shell (2).

Description

technical field [0001] The present invention relates to a battery pack formed by welding lead plates on the terminal electrodes of a plurality of rechargeable batteries, in particular to a battery pack for dissipating heat from each battery through the lead plates. Background technique [0002] In a battery pack in which a plurality of batteries are connected in series or in parallel using guide plates, it is important to efficiently dissipate heat from each battery. In particular, when a plurality of battery packs are connected in series or in parallel and the charge and discharge current is large, the heat generated by the battery is large, and it is important to efficiently dissipate the heat generated by the battery. In order to achieve this heat dissipation, a battery pack has been developed that dissipates heat from a guide plate connected to the battery (see Japanese Patent Application Laid-Open No. 2005-317456). [0003] In the battery pack disclosed in JP-A-2005-31...
