[0002] The present invention relates to a battery pack and a battery device including the same, and more particularly to a battery pack and a battery device including the same that can prevent interference between a cable portion and a housing portion. [Background technology]

[0003] A battery pack is a device that combines many battery cells to protect them from physical shocks in the external environment and perform a specific function. Typical examples are rechargeable batteries installed in smartphones, walkie-talkies, laptops, radio-controlled cars, etc.

[0004] A battery pack may include cables for connecting the outputs of multiple batteries housed therein. The cables provide an electrical path for current to flow within the battery pack. However, if the cables interfere with or are damaged by other components within the battery pack, this can lead to permanent damage to the battery pack or a safety hazard. That is, if the battery pack is used in an exposed state depending on the usage environment, continuous impact and vibration can cause the battery pack to become disconnected or short-circuit, potentially resulting in a fire or explosion. These phenomena can be caused by cable interference. Therefore, there is a need for a technology that can prevent interference between the battery pack and the cables by stably positioning the cables within the battery pack.
