The present invention relates to a battery cooling device for vehicles and a method for controlling the battery cooling device, which compactly includes battery heat exchanging means mounted on a battery to cooling the battery in a water cooling type, and a heat exchanger, air blowing means and cooling water circulating means connected with the battery heat exchanging means. Operations of the air blowing means and the cooling water circulating means are controlled in such a way as to compare battery temperature, cooling water temperature and inside air temperature of the vehicle with one another, whereby the battery cooling device can enhance efficiency of the battery by properly controlling the battery temperature, reduce power consumption and noise by properly operating the air blowing means and the cooling water circulating means, and satisfy necessary inside temperature conditions while cooling the battery using the inside air of the vehicle.
