BATTERY PACK AND METHOD OF CONTROLLING ELECTRIC FAN FOR BATTERY PACK

摘要

A battery pack is disclosed. The battery pack includes first and second temperature sensors disposed in first and second internal spaces, respectively. 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 includes a microprocessor that determines a first fan speed percentage value of the electric fan based on the first temperature level and determines a second fan speed percentage value of the electric fan based on the second temperature level. The microprocessor selects the first fan speed percentage value when the first fan speed percentage value is greater than the second fan speed percentage value.
