US 2014/0197798 A1 · SECONDARY BATTERY SYSTEM AND OPERATING METHOD OF SECONDARY BATTERY

Abstract

A secondary battery has a progressively deteriorating SOC in which battery performance deteriorates when the secondary battery is stored, and is charged and discharged by a control device. An information processing device stores a preset first threshold smaller than the progressively deteriorating SOC of the secondary battery and a preset second threshold greater than the progressively deteriorating SOC, and separates the range from the minimum SOC to the maximum SOC of the secondary battery into, at least, two regions by setting the section from the first threshold to the second threshold as a boundary to thereby cause the control device to charge or discharge the secondary battery within any of the above regions.

Dependent claims

A secondary battery system including a secondary battery having a progressively deteriorating SOC in which battery performance deteriorates when the secondary battery is stored, comprising:

a control device that, while detecting the SOC of said secondary battery, charges said secondary battery with electric power from an electric power source and supplies the electric power discharged from said secondary battery to a load;
and,
an information processing device that stores a preset first threshold smaller than said progressively deteriorating SOC of said secondary battery and a preset second threshold greater than said progressively deteriorating SOC, and separates the range from the minimum SOC to the maximum SOC of said secondary battery into, at least, two regions by setting the section from said first threshold to said second threshold as a boundary to thereby cause said control device to charge or discharge said secondary battery within any of the above regions.

An operating method of a secondary battery having a progressively deteriorating SOC in which battery performance deteriorates when the secondary battery is stored, the method comprising the steps of:

providing a control device that, while detecting the SOC of said secondary battery, charges said secondary battery with electric power from an electric power source and supplies the electric power discharged from said secondary battery to a load;
causing a computer to store a preset first threshold smaller than said progressively deteriorating SOC of said secondary battery and a preset second threshold greater than said progressively deteriorating SOC, and to separate the range from the minimum SOC to the maximum SOC of said secondary battery into, at least, two regions by setting the section from said first threshold to said second threshold as a boundary;
and
causing said control device to charge or discharge said secondary battery within any of the above regions.

An information processing apparatus for controlling a secondary battery having a progressively deteriorating SOC in which battery performance deteriorates when the secondary battery is stored, comprising:

a storing device storing a preset first threshold smaller than said progressively deteriorating SOC of said secondary battery and a preset second threshold greater than said progressively deteriorating SOC;
and,
a processing device, which separates the range from the minimum SOC to the maximum SOC of said secondary battery into, at least, two regions by setting the section from said first threshold to said second threshold as a boundary, and which causes a control device that, while detecting the SOC of said secondary battery, charges said secondary battery with electric power from an electric power source and supplies the electric power discharged from said secondary battery to a load, to charge or discharge said secondary battery within any of the above regions.
