건설장비, 산업현장의 발전기, 차량, 선박, 항공기를 포함하는 동력장치의 경우, 연료나 전지 또는 대체에너지원을 포함한 다양한 종류의 에너지를 운동에너지로 변환하여 사용한다. 그러나 이렇게 에너지를 사용하다가 필요 시에는 감속 및 정지, 즉 제동을 해야하는데, 이런 경우 불가피하게 대부분의 에너지가 열로 바뀌어 유용하지 못한 상태로 소모된다. 본 발명은 낭비되는 에너지를 발전기를 이용하여 효율적으로 회수하고, 모터에 의해 유래된 관성력을 이용하여 에너지효율을 높이는 센싱기술을 이용한 에너지회수용 선박을 제공하는 데에 그 목적이 있다. 상기 목적을 달성하기 위한 본 발명의 일 실시 예에 따른 서브발전기 제어형 에너지 회수용 철도 차량은 모터로부터 회전력을 전달 받는 회전체, 모터와 연결되는 제1구동축 및 회전체와 연결되는 제2구동축을 단속하는 클러치, 제1구동축의 회전 속도를 제2구동축의 회전 속도로 제어하는 속도제어장치를 포함하고, 속도제어장치는 제1구동축의 회전속도를 검출하는 제1구동축회전속도센서, 제2구동축의 회전속도를 검출하는 제2구동축회전속도센서, 제1구동축회전속도센서 및 제2구동축회전속도센서의 각각의 회전속도 값에 기초하여 제1구동축과 연결되는 개수가 결정되는 복수의 발전기, 를 포함한다.

    In the case of a power device including construction equipment, a power generator in an industrial site, a vehicle, a ship, and an aircraft, various types of energy including fuel, batteries, or alternative energy sources are converted into kinetic energy and used. However, while using energy in this way, if necessary, deceleration and stopping, that is, braking is required. In this case, most of the energy is inevitably converted into heat and consumed in an unusable state. The objective of the present invention is to provide an energy recovery device which efficiently recovers wasted energy using a power generator and increases energy efficiency by using the inertial force derived from a power generation device. An objective of the present invention is to provide a car for energy recovery using sensing technology, which is configured to efficiently recover wasted energy using a power generator and increase energy efficiency by using the inertial force derived from a motor. To this end, a car for energy recovery using sensing technology in accordance with one embodiment of the present invention comprises: a rotation body which receives a rotational force from a motor; a clutch which controls a first drive shaft connected to the motor and a second drive shaft connected to the rotation body; and a speed control device which controls the rotation speed of the first drive shaft to the rotation speed of the second drive shaft. The speed control device comprises: a first drive shaft rotation speed sensor which detects the rotation speed of the first drive shaft; a second drive shaft rotation speed sensor which detects the rotation speed of the second drive shaft; and a plurality of power generators, wherein the number of the power generators connected to the first drive shaft is determined based on rotation speed values of the first drive shaft rotation speed sensor and the second drive shaft rotation speed sensor.
