  • Patent number: 11385056
    Abstract: An apparatus and a method of detecting liquid leakage within a battery pack using a gyro sensor and a moisture detecting sensor. When liquid leakage of a coolant is detected, such as when a pipe of a coolant supplied for cooling (radiating heat) within a battery pack is damaged, the apparatus recognizes a liquid leakage generation position according to a slope of the battery pack by using a gyro sensor and determines whether the liquid leakage is generated based on a difference in a temperature between an upper side and a lower side of a corresponding region by using moisture detecting sensors, thereby improving accuracy of the detection of the liquid leakage according to the slope and the position of the battery pack. Particularly, the moisture detecting sensor is operated to be on only when the detection of the liquid leakage is required, thereby preventing unnecessary energy consumption.
