Abstract
A device for determining at least one range of a battery characteristic curve for a battery in a vehicle, having a measuring device for measuring battery parameters, and an analysis unit including a device for determining the current state of charge (SOC) of the battery from the measured battery parameters, a device for determining a shift value (VW) from the difference of a measured battery parameter and a standard value derived from a standard battery characteristic curve considering the determined state of charge (SOC), and a device for determining at least one range of a new battery characteristic curve by adding the shift value (VW) to the standard battery characteristic curve.
