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

    【課題】バッテリの稼働時間を向上することができるとともに、速度制御を容易に行うことができ、脱炭素社会への貢献、作業環境の改善及びメンテナンス性の向上を図ることができる電動ローラを提供する。【解決手段】電動ローラ1Dは、前後にそれぞれ設置された一対の転圧輪と、転圧輪を回転可能に支持する車体フレームと、転圧輪を駆動させる転圧輪用電動モータと、転圧輪用電動モータの回転数を制御する転圧輪用インバータと、転圧輪用電動モータ及び転圧輪用インバータに電力を供給するバッテリと、前後進レバーの傾きに応じて転圧輪用インバータに信号を出力する制御部3Dと、を有し、内燃機関を備えておらず、前記転圧輪の動力源をバッテリのみとし、制御部3Dは、停車状態で前記バッテリに充電可能な通常充電モードと、走行中に前記バッテリに充電可能な走行中充電モードと、を備えている。【選択図】図30
