BATTERY PACK AND METHOD FOR CONTROLLING ELECTRIC FAN IN BATTERY PACK

Title:

BATTERY PACK AND METHOD FOR CONTROLLING ELECTRIC FAN IN BATTERY PACK

Document Type and Number:

WIPO Patent Application WO/2015/182934

Kind Code:

A1

Abstract:

A battery pack is disclosed. The battery pack comprises first and second temperature sensors respectively disposed in first and second internal spaces. The first temperature sensor generates a first signal indicating a first temperature level of a battery cell. The second temperature sensor generates a second signal indicating a second temperature level of a DC-DC voltage converter. The battery pack further comprises a microprocessor for determining a first desired operational speed value of an electric fan on the basis of the first temperature level and determining a second desired operational speed value of the electric fan on the basis of the second temperature level. The microprocessor selects the first desired operational speed value when the first desired operational speed value is greater than the second desired operational speed value.
