  • Publication number: 20240308389
    Abstract: An electric work vehicle includes an electric motor capable of driving a body to travel, a battery to supply electric power to drive to the electric motor, the battery being chargeable by an external power supply device, a temperature detector to detect a temperature of the battery, and a controller configured or programmed to control operation of the electric motor and control a state of charging performed by the power supply device. In response to charging being performed by the power supply device, the controller is configured or programmed to set a target charging current in a state where work travel is possible after charging, based on a detected value of the temperature detector and a preset setting condition.

  • Publication number: 20240102718
    Abstract: Provided is an electrical device. In a setting unit, a right-room temperature display unit displays a set temperature or the current temperature of a first housing room. A left-room temperature display unit displays a set temperature or the current temperature of a second housing room. A right-room temperature setting button is an operation unit for a user to switch the set temperature of the first housing room. A left-room temperature setting button is an operation unit for a user switch the set temperature of the second housing room. The set temperature difference between the first and second housing rooms is controlled to be within a prescribed value. When the set temperature of one of the first and second housing rooms is changed so that the set temperature exceeds a prescribed value, a microcomputer automatically changes the other set temperature so that the set temperature difference is within a prescribed value.
