Title:
POWER SUPPLY APPARATUS SYSTEM
Document Type and Number:
Japanese Patent JP2011061979
Kind Code:
A
Abstract:
To provide a power supply apparatus system that calculates an internal resistance of a battery more satisfactorily.
The power supply apparatus system 10 is used for determining the internal resistance of an energy storage device 12 to supply electricity to a motor-generator 60 based on an amount of voltage fluctuation of voltage across of the energy storage device 12 and an amount of current fluctuation of current flowing in the energy storage device 12. The system 10 includes an accuracy improvement means for improving accuracy in determining the internal resistance of the energy storage device 12 by increasing the amount of voltage fluctuation and current fluctuation.
