  • Method and apparatus for determining an operating point-dependent change in resistance factor and vehicle
    Patent number: 9784796
    Abstract: An apparatus and a method for determining an operating point-dependent change in resistance factor (AFAP) of an energy storage device, wherein a start resistance is determined at an operating point start point in time, wherein a change in resistance between a present resistance of the energy storage device and the start resistance is determined at least at an operating point end point in time, wherein an end resistance is determined as a sum of the start resistance and the change in resistance determined at the operating point end point in time, wherein the operating point-dependent change in resistance factor (AFAP) is determined as a ratio between the end resistance and a nominal resistance proportion of the start resistance, and to methods for determining an operating point-dependent resistance.

  • METHOD AND APPARATUS FOR DETERMINING A CHANGE IN RESISTANCE OF AN ENERGY STORAGE DEVICE AND VEHICLE
    Publication number: 20160109527
    Abstract: An apparatus and a method for determining a change in resistance (?R0) of an energy storage device, wherein a measurement voltage (Umeas) of the energy storage device is detected, wherein a model voltage (Umod) of the energy storage device is determined, wherein a deviation (Ue) between the model voltage (Umod) and the measurement voltage (Umeas) is determined, wherein a measurement current of the energy storage device is detected, wherein a change (Ud) in the deviation (Ue) over time is determined, wherein the change in resistance (?R0) of the energy storage device is determined depending on the change (Ud) in the deviation (Ue) over time, and to a vehicle.
