  • Method and system for estimating battery percentage
    Patent number: 8781770
    Abstract: A method and a system for estimating a battery percentage are provided. The method includes the following steps. A coulomb counter calculated battery index (CCBI) relating to an accumulated amount of current flowing out of a battery is obtained. A battery voltage curve tracer calculated battery index (VCBI) relating to a temperature, an output voltage of the battery, and a current flowing out of the battery is obtained. A modified calculated battery index (MCBI) ranging between the CCBI and the VCBI is generated according to the CCBI and the VCBI.
