METHOD AND APPARATUS FOR DETERMINING A CHANGE IN RESISTANCE OF AN ENERGY STORAGE DEVICE AND VEHICLE |
| 摘要 |
An apparatus and a method for determining a change in resistance (ΔR0) 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 (ΔR0) of the energy storage device is determined depending on the change (Ud) in the deviation (Ue) over time, and to a vehicle. |

1. Method for determining a change in resistance (ΔR0) of an energy storage device, the method comprising:
detecting a measurement voltage (Umeas) of the energy storage device, determining a model voltage (Umod) of the energy storage device, determining a deviation (Ue) between the model voltage (Umod) and the measurement voltage (Umeas), and determining a change (Ud) in the deviation (Ue) over time, wherein the change in resistance (ΔR0) of the energy storage device is determined depending on the change (Ud) in the deviation (Ue) over time. |
