  • Patent number: 10557890
    Abstract: A method for dynamically monitoring a capacity of a battery includes estimating a first voltage threshold of the battery that is being discharged, wherein the first voltage threshold corresponds to a low capacity of the battery, and measuring a present voltage and a present current of the discharging battery. The method further includes re-scaling the present current based on the estimated first voltage threshold and the measured present voltage of the discharging battery, and calculating, based on re-scaling the measured present current, the battery's capacity before the present voltage level decreases below the first voltage threshold.

  • Publication number: 20140005855
    Abstract: A device for calculating mileage is disclosed. The device includes an estimation calculator, a mileage calculator, and a filter. The estimation calculator is configured for determining a first battery power consumed over a first predetermined distance, wherein the first battery power is determined based on a velocity and an initial remaining power. The mileage calculator is coupled to the estimation calculator, and is configured for determining an estimated remaining mileage based on the first battery power, the first predetermined distance, and a power balance. A filter is coupled to the estimation calculator and the mileage calculator, and is configured for smoothing the estimated remaining mileage and outputting a smoothed estimated remaining mileage.

  • Publication number: 20130335036
    Abstract: A balance charging detector is configured to detect a balance charging condition for a battery. The balance charging detector includes a controller and a comparing module. The controller is configured to monitor a status of the battery, access battery parameters for the battery that correspond to the status, and generate a group of balance charging parameters based on the battery parameters. The comparing module is configured to set a balance charging flag based on a comparison of the group of balance charging parameters and a set of thresholds. A balance charging signal can be generated if the balance charging flag is set to indicate presence of a condition to perform a balance charging of the battery.
