CELL BALANCE APPARATUS AND CELL BALANCE METHOD

摘要

A feeding apparatus includes a feeding unit configured to feed power in a non-contact manner to the charging apparatus mounted on a vehicle and a feeding control unit that receives vehicle detection information from a sensor configured to transmit vehicle detection information when a vehicle is detected. The apparatus executes control so that the feeding unit provided in the feeding apparatus feeds first power determined for each feeding apparatus so as to specify the feeding apparatus, transmits charging start information indicating a start of charging when feeding unit specifying information containing information to indicate the power level at which power is received from the feeding unit is received from the charging apparatus, and the received power level is determined to be within a specific power range, and executes control so that the feeding unit feeds second power in order to charge a battery unit of the charging apparatus.

1. A cell balance apparatus wherein, for at least three serially connected accumulator elements (“cells”), one end of an inductor is connected to a connecting point between adjacent cells, another end of the inductor is connected to another end of each of the adjacent cells via a switch element, and a charge is transferred between the adjacent cells via on/off control of the switch elements so as to equalize voltages of the cells, the cell balance apparatus comprising:
average-voltage calculating unit to divide the plurality of serially connected cells into two groups while maintaining a sequential order of the serial connection and to calculate an average voltage of cells within each group; average-voltage comparing unit to compare the average voltages of the two groups calculated by the average-voltage calculating unit; and on/off control unit to perform on/off control of the switch elements in accordance with a comparison result provided by the average-voltage comparing unit in a manner such that a charge is transferred from a cell located at a border of the group with a higher average voltage to an adjacent cell located at a border of the group with a lower average voltage.
