Abstract

The present invention provides a battery temperature adjusting device capable of uniformly adjusting the temperature of a plurality of battery cells without causing an increase in size and a battery device. The battery temperature adjusting device according to the present invention includes a battery case capable of accommodating battery cells in a stacked state between side wall portions, one ofthe side wall portions being provided with a first medium flow path, and the other of the side wall portions being provided with a second medium flow path. The battery case has a first communication path communicating with one end of the first medium flow path and one end of the second medium flow path, and a second communication path communicating with the other end of the first medium flow pathand the other end of the second medium flow path. A temperature control medium is guided into the first medium flow path and the second medium flow path in parallel through the first communication path or the second communication path, flows into the second communication path or the first communication path from the first medium flow path and the second medium flow path, and is discharged to the outside of the battery case. The first communication path and the second communication path are arranged on the bottom surface of the device in parallel.

Description

technical field [0001] The invention relates to a battery temperature regulating device and a battery device. Background technique [0002] A battery device including a battery unit such as a lithium-ion secondary battery is mounted on a hybrid car or an electric vehicle. In general, these vehicles require more electric power than ordinary gasoline vehicles, so the charge and discharge current of the battery device is extremely large, and the temperature rise of the battery cells becomes large. An increase in the temperature of the battery cell will degrade the performance of the battery. Therefore, when the temperature of the battery cell rises significantly, the battery cell needs to be cooled rapidly. In addition, it is sometimes necessary to heat the battery cells to an appropriate temperature when starting the vehicle in a cold region. [0003] Regarding the cooling or heating of the battery cells, it is desirable that all the battery cells accommodated in the battery...
