Abstract:
A method for controlling an information terminal according to one aspect of the present disclosure includes: when a user of the information terminal uses the electric mobile body, acquiring information indicative of a state of an electric storage device mounted in an electric mobile body from the electric storage device via a first communicator that is a communicator of the information terminal and that performs near field communication with the electric storage device; and transmitting the information indicative of the state of the electric storage device to a server device via a second communicator that is a communicator of the information terminal and that communicates with the server device.
Abstract:
A storage battery pack includes: a secondary battery; and a circuit that includes a power consumer which consumes power of the secondary battery, and that causes the power consumer to consume a remaining power of the secondary battery until a voltage of the secondary battery reaches a voltage lower than a discharge cutoff voltage.
Abstract:
A storage battery housing device includes: a casing that includes a shelf on which a storage battery pack is placed; a connection unit that is provided at the rear of the shelf and has the storage battery pack detachably and electrically connected thereto; a power reception plug that is connected to an external power source and receives power from the external power source; and a charging control circuit that uses the power received by the power reception plug to charge, via the connection unit, the storage battery pack connected to the connection unit.
Abstract:
A rental system includes a first acquirer that acquires first identification information, which is identification information of a user, from a storage device in which the first identification information is stored; a second acquirer that acquires second identification information, which is identification information of a first battery pack, which is a battery pack for rent, from a storage provided in the first battery pack; control circuitry that associates the first identification information acquired by the first acquirer and the second identification information acquired by the second acquirer with each other when the first battery pack is rented to the user; and a storage in which the first identification information and the second identification information are stored in association with each other.
Abstract:
A power storage device includes a storage battery, a mounting unit that detachably mounts the power storage device on a motor-driven moving object, an output controller that controls output of driving power from the storage battery to the motor-driven moving object, and a controller that, when the motor-driven moving object is within a particular area, causes the output controller to reduce the driving power supplied from the power storage device to the motor-driven moving object compared to the driving power when the motor-driven moving object is outside the particular area.
Abstract:
An electricity distribution device is connected to a system power supply and a battery pack, and includes: a primary power converter circuit converting DC electric power discharged from the battery pack into electric power supplied to the load; a first switch switching conducting and non-conducting states between the primary power converter circuit and the load; and a control circuitry controlling the first switch to switch the conducting and non-conducting states between the primary power converter circuit and the load. The primary power convertor circuit consumes DC electric power discharged from the battery pack, in a state where the first switch switches the non-conducting state between the primary power convertor circuit and the load, and a current value is acquired when discharging from the fully-charged state to an empty state. The fully-charged capacity of the battery pack is measured using the acquired current value.
