To more effectively utilize power.SOLUTION: A movable body includes a motor, a first battery, a first electric wire for connecting the motor and the first battery, control equipment, a second battery, a second electric wire for connecting the control equipment and the second battery, a first power converter arranged on an electric wire for connecting the first electric wire and the second electric wire to convert voltage in a bidirection, and a controller for acquiring information of charging rates of the first battery and the second battery and controlling operation of each part. The controller executes a discharge assist mode for supplying power of the second battery to the first electric wire by a second power converter when driving the motor, a charge assist mode for supplying power of the second electric wire by the second power converter and charging the second battery when regenerating the motor, and a second battery charging mode for supplying power of the first battery to the second electric wire by the second power converter, charging the second battery and performing supply to the control equipment in the case that the charging rate of the second battery is equal to or less than a threshold.SELECTED DRAWING: Figure 3
【課題】電力をより有効に活用できる。【解決手段】モータと、第一バッテリと、モータと第一バッテリとを接続する第一電線と、制御機器と、第二バッテリと、制御機器と第二バッテリとを接続する第二電線と、第一電線と第二電線とを接続する電線に配置され、双方向で電圧を変換する第一電力変換器と、第一バッテリ及び第二バッテリの充電率の情報を取得し、各部の動作を制御するコントローラと、を備え、コントローラは、モータの駆動時に、第二電力変換器で第二バッテリの電力を第一電線に供給する放電アシストモードと、モータの回生時に、第二電力変換器で第二電線に電力を供給し、第二バッテリを充電する充電アシストモードと、第二バッテリの充電率が閾値以下の場合、第一バッテリの電力を第二電力変換器で第二電線に電力を供給し、第二バッテリを充電し、かつ、制御機器に供給する第二バッテリ充電モードと、を実行させる。【選択図】図3
