Abstract
Official abstract text for this publication.
A battery pack includes a plurality of tubular batteries, holders, a storage bag, and a battery casing. The holders hold the plurality of tubular batteries. The storage bag is a flexible bag-shaped member in the interior of which the holders holding the plurality of tubular batteries are accommodated, and is filled with an insulating filler that is fluid and not solidified during use. The battery casing accommodates the storage bag in which the holders are accommodated.
First claim
Opening claim text (preview).
1 . A battery pack including: a plurality of batteries; a plurality of holders which hold the plurality of batteries; a storage bag which is a flexible bag-shaped member that accommodates the holders holding the plurality of batteries, and is filled with an insulating filler that is fluid and not solidified during use; and a battery casing that accommodates the storage bag in which the holders are accommodated. 2 . The battery pack according to claim 1 , including a discharge part that opens when a gas is generated from the batteries, and at least discharges the gas to the outside of the battery casing. 3 . The battery pack according to claim 2 , wherein the battery casing includes a case body which has a cylindrical shape and has at least one end which is open, and a lid portion that closes the portion of the case body which is open, and a space filled by the insulating filler is closed by the lid portion, and the discharge part is formed in the lid portion. 4 . The battery pack according to claim 1 , including a battery control unit that determines a state of the plurality of batteries based on a detection result of a sensor, wherein the battery control unit is accommodated in the storage bag. 5 . A propulsion device including: the battery pack according to claim 1 ; a drive source which is driven by electric power supplied from the battery pack; and a propulsion unit that uses a drive force generated by the drive source to generate a propulsive force that moves a moving body.
