Electric vehicle for energy saving using sensing technology

摘要

In the case of power equipment including construction equipment, generators at industrial sites, vehicles, ships, and aircraft, various types of energy including fuel, cells, or alternative energy sources are converted into kinetic energy and used. However, while using energy in this way, when 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. An object of the present invention is to provide an energy recovery device that efficiently recovers wasted energy using a generator and increases energy efficiency by using the inertial force derived from the power generating device. An electric vehicle according to an embodiment of the present invention for achieving the above object includes a rotating body receiving rotational force from a motor, a first driving shaft connected to the motor, and a clutch controlling the second driving shaft connected to the rotating body, and the first driving shaft. a speed control device for controlling the rotational speed to the rotational speed of the second drive shaft, wherein the speed control device includes a first drive shaft rotation speed sensor for detecting the rotation speed of the first drive shaft and a second for detecting the rotation speed of the second drive shaft and a plurality of generators whose number to be connected to the first drive shaft is determined based on the respective rotation speed values of the drive shaft rotation speed sensor, the first drive shaft rotation speed sensor, and the second drive shaft rotation speed sensor.
