Abstract:
To provide: a railway vehicle power storage device which is small-sized and light-weighted, and has an easy maintainability, a high reliability structure and a good cooling performance; and a cooling method for the device.SOLUTION: A power storage device 1 for a railway vehicle has a housing 10 accommodating one or more storage batteries in an airtight state and an electronic cooler 18 which discharges low temperature air into the housing 10. As an inner space in the housing 10 is sealed, dust invasion from an outer air can be prevented. Further, as the electronic cooler 18 is arranged in the housing 10, cold air can be supplied while airtightness in the inner space is being kept, thereby, cooling efficiency can be improved while a reliability is maintained.SELECTED DRAWING: Figure 2
