An information processing apparatus that processes information related to a rental of a battery, includes: a first acquisition unit configured to acquire performance degradation information before the rental of the battery; a second acquisition unit configured to acquire performance degradation information after the rental of the battery; and a decision unit configured to decide a treatment for a rental user of the battery, based on the performance degradation information that is acquired by the first acquisition unit and the performance degradation information that is acquired by the second acquisition unit.

Information processing apparatus and information processing method

The present invention provides an electric power unit that is mounted on a mounting object, comprising a motor; and electrical equipment for driving the motor, wherein the motor has a first attachment portion that is attached to the mounting object, and a second attachment portion to which the electrical equipment is attached.

Electric power unit and working machine

A work machine (lawnmower) comprises: a main body unit having a work unit that performs a prescribed operation; and a travel motor that generates a rotational drive force that causes at least the main body unit to travel. The work machine also comprises: a travel operation unit that issues command information relating to the rotation speed of the travel motor; and a control unit that varies the rotation speed of the travel motor commanded by the travel operation unit on the basis of variation in the load on the work unit.

Work machine

A power supply device, provided with: a battery; a capacitor connected in parallel to a load; and a main switching unit capable of switching between a state of connection and a state of disconnection between the battery and the capacitor. The power supply device is provided with a precharge circuit for reducing the current from the battery and supplying the current to the capacitor. A control unit of the power supply device first supplies electric power from the precharge circuit to the capacitor, then sets the main switching unit from a state of disconnection to a state of connection, and stops the supply of electric power from the precharge circuit while the state of connection is established.

Power supply device

In a control apparatus of a walk-behind electric lawn mower equipped with an electric motor, a blade cutter connected to the electric motor, a rechargeable battery connected to the electric motor, a motor driver circuit to adjust supply of operating electric power to the electric motor, ON/OFF of a first switching element disposed in a current path connecting the battery and the electric motor and a second switching element interposed in the current path in series with a braking resistor to allow charge current from the electric motor to the braking resistor, wherein operation of the first and second switching elements are controlled based on detected battery temperature and internal voltage of the motor driver circuit.

Electric lawn mower control apparatus

An apparatus for controlling operation of a walk-behind electric lawn mower equipped with an electric motor, a blade cutter connected to the electric motor and a rechargeable battery mounted connected to the electric motor and a motor driver circuit. In the apparatus, when an instruction to stop the electric motor is inputted, the operation of the motor driver circuit is controlled to output regenerative electric current from three-phase coils of the electric motor. At that time, it is determined whether a rotational speed of the electric motor is equal to or less than a switching rotational speed and when it is, the motor driver circuit is controlled to switch from the regenerative braking to short-circuit braking that short-circuits the three-phase coils of the electric motor.

A working machine having a belt-type continuously variable transmission in a working power transmission system includes a target working speed setting section for optionally setting a target working rotational speed of a working unit, a working unit speed sensor that detects an actual working rotational speed of the working unit, a speed reduction ratio regulation mechanism that regulates a minimum speed reduction ratio of a rotational speed of a driven pulley with respect to a drive pulley, and a control unit. The control unit controls a drive source rotational speed to bring the actual working rotational speed close to the target working rotational speed, obtains a minimum limit speed reduction ratio based upon a target minimum rotational speed of a drive source and the target working rotational speed, and controls the speed reduction ratio regulation mechanism to keep the minimum limit speed reduction ratio.

Working machine

Disclosed is a snow removal machine capable of adjusting a snow throwing direction of a snow throwing section by means of a snow throwing drive section, which comprises: a snow throwing direction sensor for detecting a snow throwing direction of the snow throwing section; a snow removal machine inclination angle sensor for detecting an inclination angle of the snow removal machine or the snow throwing section relative to a horizontal surface; and a control section that controls the snow throwing drive section to adjust the snow throwing direction of the snow throwing section based on respective detection values of the snow throwing direction detected by the snow throwing direction sensor and the inclination angle detected by the snow removal machine inclination angle sensor.
