  • RESIDUAL BATTERY CAPACITY ESTIMATION SYSTEM THAT ADDS TWO MUTUALLY PERPENDICULAR COMPONENTS AND THE METHOD THEREOF
    Publication number: 20140095090
    Abstract: A residual battery capacity estimation system that adds two mutually perpendicular components and the method thereof are provided. The mechanism detects the battery voltage, current and temperature as the sensing parameters, and uses the preset electrical characteristic parameters and capacity change to look up a table for the battery dynamic internal resistance component. The mechanism uses the sensing parameters and the Coulomb counting method to calculate the component of the battery Coulomb counting charge. Afterwards, the battery dynamic internal resistance component and the battery Coulomb counting capacity component are then added to calculate the actual residual power of the battery. The mechanism achieves the goal of increasing the accuracy in estimating the battery residual power.
