High voltage battery pack apparatus for vehicle

摘要

Disclosed is a high voltage battery pack apparatus for a vehicle which includes a cooling device having first and second battery packs which are installed in a center console of the vehicle. The first and second battery packs may be uniformly cooled through a distribution duct to improve cooling performance which minimizes the number of cooling fans that are used. Since the number of cooling fans is minimized and a discharging duct is not used, weight reduction and cost savings can be achieved.

主权项

1. A high voltage battery pack apparatus for a vehicle, comprising:
a first battery pack and a secondary battery pack installed in a center console and disposed to be separated from each other; a battery case fixed to a floor panel and configured to cover the first and second battery packs; a cooling device installed in the center console to have a cooling air flow route configured to discharge cool air to a rear side of the center console after cooling the first and second battery packs by using cooled air drawn in at a front side of the center console; an upper pad connecting an upper surface of the center console with a top surface of the battery case to prevent cooled air discharged to the rear side of the first and second battery packs from moving toward the front side in the center console after cooling the first and second battery packs, and a lower pad connecting the floor panel with a bottom surface of the battery case; and a diaphragm member installed between a bottom surface of the center console and rear surfaces of the first and second battery packs to divide an internal space of the center console into a first chamber in which the first and second battery packs are installed and a second chamber for discharging cooled air, wherein an upper grill and a lower grill connecting the first and second chambers are formed on upper and lower ends of the diaphragm member, respectively.
