Document Type and Number:
Japanese Patent JP6855890
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power supply device in which the detection accuracy decrease of a battery charge state can be reduced by suppressing the effect of voltage drop.SOLUTION: A device includes a plurality of power supplies for supplying electric power to an electric load, a power detecting unit for detecting a power supply between a plurality of power supplies and an electric load, a current control unit for controlling a current flow of each of the plurality of power supplies, and a charging state detecting unit for detecting the charging state of each of the plurality of power supplies; a plurality of power supplies generate a voltage by a chemical reaction; the current control unit determines that the power supply amount of the a power supply detected by the power detecting unit is equal to or greater than the requested electric power requested by the electric load if a part of the plurality of power supplies is the first power supply and the remainder is the second power supply, and stops the flow of the current in the second power supply while flowing current between the first power supply and the electric load; and the charging state detecting unit detects the state of charging of the second power supply in the state in which the current flow of the second power supply is stopped by the current control unit.SELECTED DRAWING: Figure 3
