Problems solved by technology

[0004] However, with the above-mentioned configuration, since the battery module is heated, there is a possibility that a temperature difference may occur depending on the position of each battery cell.
That is, with the above-mentioned structure, each battery cell cannot be heated, so there is a possibility that the temperature of each battery cell does not rise at the same time (non-uniform temperature rise occurs).

Embodiment Construction

[0036] Hereinafter, embodiments of the present disclosure will be described in detail based on the drawings. In addition, the battery pack 10 according to the present embodiment (refer to figure 1 ) is an auxiliary power supply mounted on an autonomous vehicle (not shown) that runs on electric power. That is, the battery pack 10 is a backup power source for enabling the autonomous vehicle to travel a certain distance even when a battery stack (not shown) serving as the main power source fails to function due to a failure or the like.

[0037] In addition, for convenience of explanation, in each drawing, the arrow UP, which is appropriately shown, is the upward direction of the battery pack 10 , the arrow FR is the front direction of the battery pack 10 , and the arrow RH is the right direction of the battery pack 10 . . Therefore, in the following description, unless the directions of up-down, front-rear, and left-right are described unless otherwise specified, the up-down d...

Abstract

This battery pack is provided with: a cell stack configured so as to include a plurality of battery cells arranged in the thickness direction; a case accommodating the cell stack; a heating substrate having a plurality of metal patterns that generate heat by energization, the heating substrate being disposed inside the case so that each metal pattern faces each of the battery cells; and a plurality of thermally conductive sheets interposed between the plurality of battery cells and the plurality of metal patterns, respectively.

Description

technical field [0001] The present disclosure relates to battery packs. Background technique [0002] Conventionally, there is known a battery pack in which a sheet heater is attached to the inner surface of a lid of a storage container in which a battery module including a plurality of battery cells is accommodated (for example, see Japanese Patent Laid-Open No. 2014-194904). [0003] For a battery module composed of a plurality of battery cells, the performance is degraded at low temperature. Therefore, in this battery pack, by heating the storage container with the sheet heater, the battery module is indirectly heated through the storage container. [0004] However, in the above-described configuration, since the battery module is heated, there is a possibility that a temperature difference may occur depending on the position of each battery cell. That is, with the above-described configuration, it is not possible to heat each battery cell, and therefore there is a poss...
