A thermal management device for a battery pack 104 of an UAV is disclosed. The thermal management device 100 comprises an insulating enclosure 102 that is made of a material comprising at least an EPP foam for enclosing the battery pack 104, and one or more heating coils 110. The heating coils 110 are electrically powered from an external power source 112 for pre-heating the insulating enclosure 102 to a predefined temperature before flight of the UAV. The EPP foam of the insulating enclosure 102 provides high thermal insulation for retaining the heat of the insulating enclosure 102 for heating the battery pack 104 and maintaining the temperature of the battery pack 104 above a threshold temperature when the UAV flies in a sub-zero ambience temperature. The insulating enclosure 102 with the one or more heating coils 110 are configured to provide uniform heat distribution across the battery pack 104.
