초록 ▼

The present invention provides a system and method for operating a rechargeable battery, the system comprising: current maintaining device for maintaining a predetermined current to the rechargeable battery until the rechargeable battery reaches a predetermined maximum voltage; voltage maintaining device for maintaining a predetermined voltage to the rechargeable battery until a predetermined minimum current is delivered to the rechargeable battery; determining device for determining a cyclical charge value delivered to the rechargeable battery by the current maintaining device and the voltage maintaining device during a cycle; and a correction device for correcting the determining device when charge is not being delivered to the rechargeable battery, on the basis of the charge value.

대표청구항 ▼

What is claimed is: 1. A system for operating a rechargeable battery, said system comprising:means for charging said rechargeable battery to a predetermined maximum voltage;means for determining a first dynamic charging range for the rechargeable battery for a first plurality of charging cycles; andmeans for calculating an offset error for said determining means while there is no more than a relatively low load on the rechargeable battery,wherein the means for charging comprises:means for delivering a predetermined charging current to the battery until the battery is charged to the predetermined maximum voltage; andmeans for successively delivering progressively smaller charging currents to the battery until a predetermined minimum charging current of the progressively smaller charging currents is reached, wherein each of progressively smaller charging currents is delivered to the battery until the battery is charged to the predetermined maximum voltage.
