Problems solved by technology
However, the heat dissipation method of adding a heat-conducting frame and a heat-conducting shell requires a high contact surface between the cell and the heat-conducting material through single heat conduction, and the conduction efficiency is limited.
Active cooling systems such as air cooling and water cooling require additional components, increasing energy consumption and weight, which is not conducive to the endurance of unmanned aerial vehicles

Abstract
A battery (100), comprising a casing (11), the casing (11) being provided with an accommodation chamber (111); and a plurality of electric cores (13), the plurality of electric cores (13) being accommodated in the In the accommodating cavity (111), and arranged in layers; wherein, the plurality of electric cores (13) are arranged at intervals to form a plurality of air passages (131); the side of the housing (11) An air guide hole (112) is also provided, and the air guide hole (112) communicates with the air channel (131), so that the air flow outside the housing (11) can pass through a part of the air guide The hole (112) enters the accommodating cavity (111), so as to blow to the plurality of electric cores (13), and flow through the air channel (131), and flow out from another part of the air guide hole (112), Therefore, the heat generated by the plurality of battery cells (13) is taken away. The battery (100) can be used in an unmanned aerial vehicle (200).
Description
technical field [0001] The invention relates to an energy storage device, in particular to a battery and an unmanned aerial vehicle with the battery. Background technique [0002] UAVs usually use batteries to provide energy sources to ensure the normal operation of UAVs. When the power battery of the unmanned aerial vehicle is in use, its high-rate discharge generates a lot of heat, which leads to a serious problem of temperature rise. In addition, the power batteries of unmanned aerial vehicles are often connected in series and parallel with multiple cells, the internal heat of the battery is not easy to dissipate, the internal temperature is uneven, and the local temperature rise is too high, which further accelerates battery decay, shortens battery life, and affects safety performance. [0003] At present, the heat dissipation method for the multi-series parallel lithium-ion battery pack is to install a heat-conducting frame and a heat-conducting shell to transfer the i...
