A vehicle battery cooling device including a battery case containing a battery for generating a high voltage and disposed in a space between a pair of right and left side panels at a rear side of a vehicle, a cooling fan disposed at a location overlapping the battery case in a vertical direction of the vehicle and configured to send cooling air to the battery case, and a duct placed in a space between the battery case and the side panels in a width direction of the vehicle so as to communicate the cooling fan and the battery case with each other. The duct is fastened to the battery case via a bracket, the bracket has an inner space having a U-shaped cross section, and the duct is disposed inside the inner space.

Cooling device of vehicle battery

A coverof a battery pack case has an intake port and an exhaust port. With in the battery pack case, battery accommodation sections respectively accommodate battery modules and a junction box accommodation section. A supply flow path and an exhaust flow path are provided at ends of each of the battery accommodation section. A guide is provided between the cover and the battery modules accommodated in the battery accommodation portions. The guide and a lower surface of the cover define a distribution flow path. The air introduced from the intake port flows to the exhaust port through the distribution flow path, supply flow paths, clearances between battery cells, exhaust flow paths, and exhaust port. The battery cells are efficiently cooled.
