ADAPTIVE FAN SPEED CONTROL FOR THERMAL MANAGEMENT OF A BATTERY

A method of controlling a fan speed for a battery unit includes determining power discharge and a current temperature of a battery unit and obtaining a relationship between fan speed for the battery unit and temperature of the battery unit based on the power discharge and the current temperature of the battery unit. The method further includes identifying a minimum fan speed based on the relationship between fan speed and temperature and a maximum operating temperature of the battery unit and controlling the fan by setting the speed of the fan to the minimum fan speed.
