Abstract: A stationary power storage system includes a control device configured to control a current value of each of a plurality of power storage devices. Each of the plurality of power storage devices is configured to be switchable between conduction and interruption in accordance with a command from the control device. The control device is configured to select at least one power storage device to be used for energy management from the plurality of power storage devices and interrupt a current of at least one power storage device that has not been selected. The control device is configured to, for the energy management, control a current value of the power storage device that has been selected, and during execution of the energy management, acquire an output value, when no current flows, of at least one current sensor corresponding to at least one power storage device that has not been selected.

Abstract: A control device of a charging device performs constant current charging, when starting charging at time t0. When the SOC of a battery reaches a set value ? at time t1, the charging current is limited to gradually decrease. When the battery voltage VB of the battery reaches a charging completion voltage VBb at time t2, charging is terminated. When the charging current is small, the polarization is small, and therefore, the charging completion voltage VBb can be set to a value corresponding to the full state of charge, to charge the battery to a state close to the full state of charge without relying on CV charging.

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.

Abstract: Provided is an electric device made more convenient by being configured such that the temperature of a wide area in each accommodation section can be individually adjustable. In an electric device, a first refrigerant pipe is provided to a right-side member constituting a side surface of a first accommodation chamber, and a second refrigerant pipe is provided to a left-side member constituting a side surface of a second accommodation chamber. The first refrigerant pipe and the second refrigerant pipe are independent of each other. A regulating valve includes: a first regulating valve provided to the first refrigerant pipe, and a second regulating valve provided to the second refrigerant pipe.

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.

Abstract: In order to obtain an illuminating device that can carry out optimum illumination corresponding to various usage modes, the illuminating device includes a grip held by an operator and extending in a vertical direction; a battery connected to a lower end of the grip; and an irradiation part connected to an upper end of the grip, and the irradiation part is connected to the grip so that the irradiation part can be turned between a first position extending from the upper end of the grip to an upper side and a second position extending from the upper end of the grip to a lower side, a first lamp is provided on a grip-side end part of the irradiation part, and a second lamp is provided on a side surface of the irradiation part.

Abstract: A power tool includes a housing including: a body part having a substantially cylindrical shape and extends in a front-rear direction; and a handle part connected to the body part. The body part includes: a driving source; a power transmission mechanism part configured to transmit a driving force of the driving source; and a tip tool holding part to which the driving force of the driving source is transmitted from the power transmission mechanism part. The handle part includes a switch. A top part protruding from a surface of the handle part is formed on a side surface of the handle part along a longitudinal direction of the handle part. At least a portion of the top part is arranged at a position deviating rearwards from a center of the handle part in the front-rear direction.
