Abstract: An electrically-driven working apparatus in one aspect of an embodiment of the present disclosure comprises: a battery; an abnormality detection unit; a power supply path; a first disconnection unit; a second disconnection unit; and a control unit. The control unit activates the first disconnection unit to disconnect the power supply path if either of an overload or an over discharge of the battery is detected by the abnormality detection unit, and subsequently determines whether discharge from the battery has stopped after activating the first disconnection unit, and activates the second disconnection unit to disconnect the power supply path if discharge from the battery has not stopped.

Abstract: A battery pack for a motor-driven appliance comprises a battery including a plurality of cells, a cell discharge unit that discharges each cell individually, a voltage detection unit that detects each cell voltage, a target cell determination unit, and a discharge control unit. When at least one cell having the cell voltage equal to or smaller than a specified threshold is present, the cell voltage that is the smallest among them is set as a smallest cell voltage, and when at least one other cell having the cell voltage larger than the smallest cell voltage by a defined value or more or having the cell voltage larger than the threshold by the defined value or more is present, the target cell determination unit determines the at least one cell as a target cell, and the discharge control unit causes the target cell to be discharged by the cell discharge unit.

Abstract: A main body of a motor-driven appliance is configured such that a plurality of battery packs are attachable thereto. Each of the battery packs contains a battery. The main body of the motor-driven appliance acquires, from each of the plurality of battery packs, discharge capacity information indicating a discharge capacity of the contained battery. The main body of the motor-driven appliance sets at least one control parameter to control discharge from a power source to a motor, in accordance with at least the discharge capacity information of a battery with a lowest discharge capacity, among the acquired respective discharge capacity information.

Abstract: A random number generating device includes a processing request part, a receiving part, a counting part, and a random number generation part. The processing request part makes a request for a predetermined processing to a processing requested object. The receiving part receives a response from the processing requested object in response to the request. The counting part performs a counting operation to increase or decrease a count value with a predetermined cycle, the counting operation being started at least prior to receipt of the response. The random number generation part acquires at least one count value of the counting part at least one predetermined acquisition timing after the receipt of the response is started, and generates a random number by using the at least one count value that is acquired.
