Claim Text:
1. A cooling blower control system for a high-voltage battery, the cooling blower control device comprising: a first sensor configured to sense an internal temperature of a battery pack assembly; a second sensor configured to sense an output current of the battery pack assembly; a first controller configured to perform fuzzy control by using outputs of the temperature sensor and the current sensor as inputs to output a cooling blower's duty ratio; and a second controller configured to perform pulse-width modulation (PWM) control by using an output of a fuzzy controller as an input to output a control signal for driving the cooling blower, wherein the first controller is the fuzzy controller which comprises:
