Electric roller

Abstract

To provide an electric roller capable of increasing the uptime of a battery while easily controlling the speed and achieving contribution to the carbon-free society, improvement of the working environment and enhancement of maintainability.SOLUTION: An electric roller 1D includes: a pair of rolling wheels respectively provided at the front and back; a vehicle body frame rotatably supporting the rolling wheels; a rolling wheel electric motor for driving the rolling wheels; a rolling wheel inverter for controlling rotational speed of the rolling wheel electric motor; a battery for supplying electric power to the rolling wheel electric motor and the rolling wheel inverter; and a control unit 3D that outputs a signal to the rolling wheel inverter in accordance with the inclination of a forward / reverse lever. The electric roller does not comprise any internal combustion engine, and uses only the battery as a power source of the rolling wheels. The control unit 3D has a normal charging mode capable of charging the battery when the vehicle is stationary, and a travel charging mode capable of charging the battery during travel.SELECTED DRAWING: Figure 30
