장애인용 전동 스쿠터용 태양 전지를 이용한 충전 장치{Solar cell charging apparatus for electric scooter for disable person}Solar cell charging apparatus for electric scooter for disabled person

본 발명은 장애인용 전동 스쿠터의 배터리 충전을 위한 충전 장치에 관한 것으로 특히, 전동 스쿠터의 충전을 태양 전지를 이용하여 장애인용 전동 스쿠터용 태양 전지를 이용한 충전 장치에 관한 것이다. The present invention relates to a charging device for charging a battery of a disabled electric scooter, and more particularly, to a charging device using a solar cell for a disabled electric scooter using a solar cell to charge the electric scooter.

일반적으로 전동 스쿠터는 축전지(이차전지)를 이용하여 전동 스쿠터의 구동에 필요한 동력을 얻는다. 전동 스쿠터는 3륜 또는 4륜 수송차량으로서 저속(보통 15km/h 이하)으로 운행하며, 장애인과 노인들의 근거리 이동, 쇼핑, 공항 또는 공장 내에서의 이동, 실내청소, 골프 카트 등 주로 사람이 많이 사는 도심이나 공해를 허용하지 않는 환경에서 저속으로 운행되고 있다. 전동 스쿠터의 주 동력원으로서의 축전지는 공해와 소음은 없으나 한 번의 충전으로 주행할 수 있는 거리가 짧고(40km 이하), 주행 후 다시 충전하는데 장시간(약 8~12시간)이 소요된다. In general, the electric scooter uses a storage battery (secondary battery) to obtain the power required to drive the electric scooter. Electric scooters are three- or four-wheeled vehicles that operate at low speeds (usually 15 km / h or less), and are primarily used by people with disabilities and the elderly, shopping, airports or factories, indoor cleaning, and golf carts. The company operates at low speeds in the city or in an environment that does not allow pollution. Batteries as the main power source of electric scooters have no pollution and noise, but they can run with a single charge (40 km or less), and take a long time (about 8 to 12 hours) to recharge after driving.

따라서, 이러한 장시간의 충전과 짧은 운행 가능 시간으로 인해, 스쿠터 축전지의 빈번한 과다 방전으로 인한 수명의 단축으로 대략 약 1~2년 정도 사용하면 새로운 축전지로 교체해야 하는 문제가 있다.Therefore, due to such a long charge and short running time, there is a problem that should be replaced with a new battery when used for about 1 to 2 years due to the shortening of the life due to frequent over-discharge of the scooter battery.

이에 본 발명은 상술한 사정을 감안하여 창출된 것으로, 본 발명의 목적은 전동 스쿠터의 축전지가 과다 방전되는 것을 감소시킬 수 있는 장애인용 전동 스쿠터용 태양 전지를 이용한 충전 장치를 제공하는 것이다.Accordingly, the present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a charging device using a solar cell for a disabled electric scooter that can reduce the excessive discharge of the battery of the electric scooter.

본 발명의 다른 목적은 전동 스쿠터가 일반 전기를 사용할 수 없는 운행 중이거나 정차하는 경우에도 충전이 가능하여 축전지의 충전 정도를 유지시켜 줄 수 있게 하는 장애인용 전동 스쿠터용 태양 전지를 이용한 충전 장치를 제공하는 것이다.It is another object of the present invention to provide a charging device using a solar cell for the electric scooter for the disabled to enable the electric scooter to maintain the charging degree of the battery by being able to charge even when driving or stopping when general electricity cannot be used.
