Embodiment Construction

[0021] The invention will now be described with reference to the accompanying drawings and in conjunction with preferred embodiments.

[0022] figure 2 It is a structural block diagram of the device for correcting the remaining power of the smart battery according to the present invention, and particularly shows the structure of the control unit embedded in the smart battery.

[0023] exist figure 2 In, reference numeral 10 denotes a battery unit used for charging in the battery, 20 denotes a sensor for detecting the voltage, current and temperature of the battery unit 10, and 30 denotes a table information storage unit which includes a predetermined charge A state of charge (SOC) fuel gauge, where the battery charge is recorded as a function of the battery's asymptotic SOC and number of cycles, and a table of predetermined FCC corrections, where the FCC corrections over cycles are linearized by segment.

[0024] In the present invention, the state of charge (SOC) represen...

Abstract

A method for counting cycle count of a smart battery, a method and device for correcting full charge capacity of a smart battery, which is used as reference capacity for indicating correct remaining capacity of the battery, are disclosed. The present invention increase cycle count that is a standard for updating FCC in gradual floating variables in consideration of SOC to obtain continuous cycle count. FCC information is updated when the battery has been fully charged or the integer of the cycle count increases 1 using a predetermined FCC correction table in which FCC correction values varying with the cycle count are linearized by sections. This improves reliability in actually corrected FCC information and increases accuracy in the remaining capacity indicated on the basis of the FCC information.

Description

technical field [0001] The invention relates to an intelligent battery, and in particular to a method for calculating the number of cycles of the intelligent battery with asymptotic floating point variables. In addition, the present invention relates to a method and apparatus for correcting a full charge capacity (FCC) of a smart battery using a method of calculating the number of cycles of the smart battery as a reference power indicating an accurate remaining power of the smart battery. Background technique [0002] Generally, portable electronic devices, such as notebook computers, PDAs, cellular phones, etc., include batteries on which the current remaining power and charging time are displayed, and such batteries are called smart batteries. The smart battery has a predetermined internal control unit to provide the electronic equipment containing the battery with the current temperature, working status and remaining power of the battery. [0003] The remaining capacity ...
