There is provided a battery energy discharge device in which water is injected into a battery pack, for example, at the time of the occurrence of an abnormal situation in a vehicle, whereby the water is converted into an electrolyte aqueous solution having a high electric conductivity by the electrolyte substance provided in the battery pack, heating is suppressed by the electrolyte aqueous solution, and the battery can be discharged quickly. An electrolyte substance M is provided inside a battery pack 5 accommodating a vehicle drive battery 8 or inside an air duct 64 (water injection route) connected to the battery pack; in particular, in the case that terminal electrodes are disposed on the upper side of the battery 8, the height position H of the electrolyte substance from the lower face of the battery pack is set to a position in which the electrolyte substance is dissolved in water after the battery has securely obtained a predetermined water-submerged height, whereby the cooling performance for the battery can be obtained securely at the time when the electrolyte aqueous solution makes contact with the terminal electrodes of the battery.
