PROBLEM TO BE SOLVED: To provide a battery pack capable of suppressing excessive increase in temperature.SOLUTION: A battery pack 1 comprises a battery module 6 containing a battery cell 8, a heat storage part 11 including a heat storage container 12 containing a heat storage material 13, cooling paths 18a, 18b through which heat of the heat storage part 11 is propagated and from which the heat is emitted, and a cooling source 21 configured to cool the heat storage part 11. A heat storage material that absorbs heat when a solid changes into a liquid and radiates heat when a liquid changes into a solid. The heat storage container 12 is thermally connected to a battery module 6. By driving the cooling source 21, a cooling medium circulates through the cooling paths 18a, 18b, and heat of the heat storage part 11 emitted into the paths is discharged to the outside. |
