A wearable battery pack includes a battery pack body, a battery cell and a housing accommodating a battery cell and a wearable device capable of wearing so that the battery pack body at least be worn on a user's back. The battery pack body has a heat dissipation channel running through one side of the battery pack body to the opposite side. The side of the battery pack body which is penetrated by the heat dissipation channel is located between the back of the user and the other side when the user carries the battery pack body.

A battery pack includes a housing, a battery cell group accommodated in the housing, a plurality of battery pack connection terminals coupled to the connection terminals of an electrical device, including a battery pack positive power terminal electrically connected to a positive pole of the battery cell group, a battery pack negative power terminal electrically connected to a negative pole of the battery cell group, a first battery pack terminal to transmit a first type of data, and a second battery pack terminal to transmit a second type of data. Also, a data transmission method between the battery pack and the electrical device enables data collection for data analysis while ensuring normal operation of the battery pack and the electrical device.

One embodiment provides an electronic device, including: a battery pack stack comprising at least two battery packs; wherein the battery pack stack comprises at least one cumulative heat reducing component positioned between the at least two battery packs. Other aspects are described and claimed.

A method and apparatus may be used for power source time division multiplex for thermal management and extended operation. The apparatus includes a primary power source, a secondary power source, and a processor. The processor obtains an internal temperature measurement of the image capture device. The processor may determine a thermal zone based on the internal temperature measurement. In an example where the determined thermal zone is a first thermal zone, the processor may be configured to draw power from the secondary power source. In an example where the determined thermal zone is a second thermal zone, the processor may be configured to alternately draw power from the primary power source and the secondary power source. In an example where the determined thermal zone is a third thermal zone, the processor may be configured to draw power from the secondary power source.

A portable radio device incorporating active thermal mitigation systems, and methods of use thereof. An example radio device incorporating an active thermal mitigation system may comprise a portable radio device selectively connectable or otherwise interoperable with a power adapter or battery device, wherein the power adapter or battery device includes an active thermal mitigation system. The system may include a micro-fan, blower, or other similar device configured to generate airflow, and may be configured to direct a flow of air or other fluid towards the radio device. The system may further include one or more fins or other features for directing and/or enhancing fluid flow, as well as sensors and control features to vary flow depending on temperature of the radio device or other variables. Thus, the system allows for the continuous cooling the radio device via convection without requiring the incorporation of the active thermal mitigation system within the radio device.
