Title:
COOLING DEVICE
Document Type and Number:
Japanese Patent JP2017128249
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a cooling device that is restrained from increasing noise and furthermore can secure cooling performance to a battery.SOLUTION: The cooling device comprises a duct for flowing cooling air which is supplied to a battery pack to a fan with a built-in AC power source and a fan with a built-in PCU. When battery pack temperature Tb is equal to or more than a threshold Ttha and equal to or less than a threshold Tthb, a battery cooling fan is driven and the fan with the built-in AC power source is driven (steps S110-S140). When the battery pack temperature Tb is equal to or more than the threshold Tthb, the battery cooling fan, the fan with the built-in AC power source, and the fan with the built-in PCU are driven (steps S110, S150-S190). Therefore, cooling performance to the battery pack can be secured while suppressing increase of the noise.SELECTED DRAWING: Figure 2
