Abstract

The invention relates to a method performed by a control arrangement for setting a remaining Distance to Empty parameter in an electric vehicle, wherein the control arrangement is configured to estimate a first remaining Distance to Empty value at least based on a remaining State of Charge of the vehicle's energy storage. The method comprises when the first remaining Distance to Empty value is estimated to be below a Distance to Empty threshold value determining a second remaining Distance to Empty value at least based on an actual distance travelled since the first remaining Distance to Empty value was estimated to be below the Distance to Empty threshold value. The method further comprises setting the remaining Distance to Empty parameter at least based on the second remaining Distance to Empty value. Hereby, the risk of rapid decrease of the Distance to Empty parameter at low battery charging level is mitigated and the Distance to Empty parameter will be perceived as correct which means that unnecessary stress is avoided when low State of Charge of the vehicle's energy storage is reached. The invention also relates to a control arrangement, a vehicle comprising the control arrangement, a computer program, and a computer-readable medium.
