摘要： A battery control device is connected to a plurality of battery cells. The battery control device includes a voltage value calculator, a communicator, and a voltage value updater. The voltage value calculator calculates, based on a current flowing through a plurality of battery cells, a voltage of each battery cell. If the battery control device is connected to a charge control device, the communicator receives information relating to a voltage of each battery cell, which has been detected by a voltage detector in the charge control device, from the charge control device. The voltage value updater updates the voltage calculated by the voltage value calculator based on the voltage information received by the communicator.

摘要： A battery ECU acquires open circuit voltages of a plurality of battery cells that are divided into a plurality of groups A, B, C using a plurality of detecting units, and calculates SOCs of the battery cells based on the open circuit voltages. Then, the battery ECU selects the group to which the battery cell having the largest SOC among the SOCs of the plurality of battery cells belongs, and selects the battery cell to be discharged in the selected group. A series circuit composed of a resistor and a switching element is connected in parallel with each battery cell. The battery ECU turns on the switching element corresponding to the selected battery cell. At this time, the battery cell is connected to the resistor, thus being discharged.

摘要： An SOC of each battery cell is periodically detected, and an SOCmin and an SOCmax are determined. Battery cells having the SOCs larger than SOCmin+α are selectively discharged. After an elapse of a preset equalization processing time period, discharge of all the battery cells is stopped. The equalization processing time period is set based on a rate of change in the SOC of the battery cell subjected to discharge and a rate of change in the SOC of the battery cell not subjected to discharge such that a magnitude relationship between the SOC of the battery cell having the SOCmin and the SOC of another battery cell is not reversed.

摘要： When a voice is inputted to an operation terminal (200), the audio input is subjected to voice recognition in a voice recognizing unit (107) and keywords are extracted. A search condition creating unit (110) creates a search condition from the extracted keywords. A search unit (111) searches for control items that can be options to choose from. These control items are displayed on a television screen by an output information creating unit (113). A user uses the operation terminal (200) as a pointing device to select and point a desired control item among the displayed control items. Thereafter, a “select” key of operation keys is operated to obtain control codes for this control item. The control codes are sent to a television set (300).
