Abstract

A cooling control apparatus for a battery pack according to the present invention comprises: a temperature sensor which measures the temperature of a battery pack; a blower module which makes a cooling medium flow into the battery pack by driving a fan; and a control unit which controls the blower module to be driven so as to allow for different flow rates of the cooling medium to flow into the battery pack depending on the temperature information inputted from the temperature sensor.; The present invention drives a differential cooling mechanism according to temperature distribution or the situation of the battery pack, so that it is possible to both stabilize battery pack operation and optimize energy utilization for greater efficiency, and it is also possible to more effectively troubleshoot the error states of the cooling system of the battery pack, and the method can be applied to the battery control and user interfacing, thereby making it possible to provide a cooling control apparatus which is more stable and enhances user convenience.

Description

technical field [0001] The present invention relates to an apparatus and method for diagnosing and controlling a cooling system of a battery pack, and more particularly to an apparatus for use as a secondary battery pack for an electric vehicle (EV), a hybrid vehicle (HEV), etc. A cooling control device and method capable of applying different cooling methods depending on temperature conditions of a secondary battery pack and capable of minimizing a risk of a cooling system malfunctioning. [0002] This application claims priority from Korean Patent Application No. 10-2010-0084145 filed on Aug. 30, 2010, the entire contents of which are disclosed in the specification and drawings are incorporated herein by reference. Background technique [0003] Secondary batteries have high applicability depending on the kind of product and excellent electrical characteristics, such as high energy density, and thus are generally used as power sources of electric vehicles (EV) or hybrid veh...
