  • Patent number: 9722443
    Abstract: There is a request for charging and discharging of a lithium-ion battery with as less degradation as possible. In an operation using only binary values as in conventional technology, however, in a charged state in which the battery is used, there is a high possibility that the battery is used toward accelerating the degradation thereof. In a power distribution device for distributing power between a plurality of batteries and a plurality of customers, when distributing the power of the batteries to the loads of the customers, by being based at least on the degradation information of the batteries, the state of charge, and the temperature data of the batteries, a battery discharging function is achieved that makes the degradation of the batteries minimum.

  • Publication number: 20150326040
    Abstract: Charging equipment and a charge control unit are provided, in which a plurality of devices mounted with battery can be simultaneously charged by the single charging equipment. Further, a method of controlling charge and a method of receiving charge are also provided. The charging equipment supplies electric power to the battery for charging, comprising a power output part which outputs DC power used for charging, a plurality of user operation units which can be connected with a vehicle equipped with a battery as a device mounted with battery, and the charge control unit which controls a power supply from the power output part to the user operation unit. Herein, the charge control unit distributes the electric power outputted from the power output part to supply the distributed power to the user operation unit connected with the vehicle.

  • Publication number: 20150115969
    Abstract: A storage battery analysis system includes a storage device storing data of time series variation of a voltage value and a current value during a charging period of a storage battery and data of time series variation of the voltage value and the current value during the charging period of the storage battery; and an arithmetic device that executes a process to read out the time series variation data of the voltage value and the current value during the charging period of the battery, compares the read time series variation data, identifies a difference in the time series variation between the initial usage period and the analysis period, and stores in the storage device the difference as an index indicating a degradation state of the storage battery.

  • Publication number: 20030191742
    Abstract: Page access log information, answer log information and click log information record the access counts to respective contents. A contents check list sets values corresponding to an aimed value of the access contents to contents as a target, and sets a measure when the contents do not obtain the aimed value. A contents server refers to a corresponding log, and sums the access count to contents from the start date of release of the contents to the latest date when the log can be acquired on the day of check before the time limit. The contents server refers to the list, and checks whether this access count has reached its aimed values or not. When the access count has not reached the aimed value, the contents server performs a measure for the contents.

  • Publication number: 20030033390
    Abstract: A program distribution system includes a program transmitting device configured to transmit a program content to a remote location. A viewer terminal device is configured to receive the transmitted program content and output the content to a display. The viewer terminal device is further configured to provide a viewer with a choice of viewing the content in a first viewing setting or a second viewing setting. The first viewing setting displays one or more commercials at predetermined time intervals. The second viewing setting displays the one or more commercials at different times than the predetermined time intervals.

  • Publication number: 20030018545
    Abstract: In an online shopping system having a shopping basket function capable of conducting an order process in onetime by storing items to be purchased in a purchase list, an interface for the shopping basket function is provided as a shopping basket window separate from a catalog window for displaying item data of the online shopping. The shopping basket window is placed near a pointer displayed on the catalog window and a display position thereof is moved in linkage with the movement of the pointer. The shopping basket function includes a list of items to be purchased which is a main body of the shopping basket, a function to add item data to the list, and a function to change the item information registered in the list. Preferably, the shopping basket main body is not constantly displayed. Instead, an interface function to recall the content display of the shopping basket is provided in the shopping basket window.
