Abstract:
A control method for a battery storage apparatus including a battery pack includes (a) receiving an identifier for identification of an external battery pack via a near field communicator provided in the battery storage apparatus when the external battery pack is present within a communication range of the near field communicator and (b) outputting a piece of association data, in which the identifier and a piece of apparatus information on the battery storage apparatus are associated with each other, to a server apparatus via a communicator.
Abstract:
An information displaying method includes acquiring a battery identifier to identify a battery pack associated with a display device and a device identifier to identify a device to which the battery pack has been mounted, and causing a monitor of the display device to display information indicating that the battery pack corresponding to the acquired battery identifier has been mounted to the device corresponding to the acquired device identifier.
Abstract:
A method including: receiving identification information of a charging device including individual identification information of the charging device, and identification information of a power storage device, which is connected to the charging device, including individual identification information of the power storage device, from at least one of the charging device and the power storage device; determining the possibility of charging the power storage device from the identification information of the power storage device and the identification information of the charging device received; and transmitting information indicating the determined possibility of charging the power storage device to at least one of the charging device and the power storage device.
Abstract:
A system includes a first circuit in which storage battery units are connected in series, second circuits, adjusters that adjust the amounts of the currents flowing through the second circuits, and a controller that performs at least one of first control and second control. The first control is control in which the controller causes the adjusters to make the voltage of a first storage battery unit higher than the voltage of a second storage battery unit having a higher degree of degradation than the first storage battery unit by adjusting the amounts of the currents flowing through the second circuits and then stops a charge. The second control is control in which the controller causes the adjusters to make the voltage of the first storage battery unit lower than the voltage of the second storage battery unit by adjusting the amounts of the currents flowing through the second circuits and then stops a discharge.
Abstract:
