Title:
POWER SUPPLY DEVICE
Document Type and Number:
Japanese Patent JP2016127770
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suitably suppress the deterioration of a power supply caused by a rise of a temperature.SOLUTION: A power supply device comprises: a power supply in which a voltage value is lowered in at least a part of a region as a charge amount cSOC(State Of Charge) of a capacitor being a power storage element which can charge and discharge electricity similar to a secondary battery is lowered; temperature detection means for detecting a temperature Tc of the power supply; usable range changing means for raising an SOC usable range cWout minimum value of a power output of the power supply as the temperature of the power supply is high while maintaining an SOC usable range cWin maximum value of a power input of the power supply constant; and center SOC changing means for raising a center SOC being a control target as the temperature of the power supply is high.SELECTED DRAWING: Figure 4
