산업용 드론은 배터리 용량의 한계로 인해 비행시간이 제약을 받는다. 이러한 문제를 극복하기 위해 드론스테이션의 자동충전 기능이 연구되고 있지만. 기존 산업용 드론의 배터리팩 구조는 자동충전에 적합하지 않다. 이에 본 논문은 드론 스테이션의 자동충전에 적합한 배터리팩 구조를 제안한다. Industrial drones have restrictive flight time because of battery capacity limitation. To overcome the drawback, auto-charging mode of drone stations has been studied, but conventional battery pack forms of industrial drones are unsuitable for implementing the auto-charging mode on drone stations. Accordingly, this paper proposes a drone-battery-pack structure concerned the auto-charging mode with drone stations.

Recently, projects to employ supercapaciotrs as a main-battery of micro mobilities have been researched. This paper developed a fast charger for supercapacitor based battery packs. The goal of the charger is to charge more than ninety percent within ten minutes. The battery pack has 8 kWh for a total capacity. Four 10S14P (10 series 14 parallel) battery modules are connected in the battery pack by series and parallel formats. The fast charger builds to simultaneous charging to supercapacitors each parallel line in the battery pack, and the charger consists of forty charging channels. Each charging channel contains a power module, two current boards, a control board, and a microprocessor board. The Charging channel has 4.2 V and 300 A to maximum output. As a result of the charging test, the fast charger makes an 8 kWh supercapacitor based battery pack to over ninety percent charge in under ten minutes.
