Nach der Aussage zeigt der Wert die beste Präzision wenn man den Akku in einem Rutsch auf ebener Fläche möglichst ohne Reku von voll bis RE leert. Kürzere Fahrten mit Unterbrechungen und Neustarts verfälschen minimal die Bestimmung der SOC => Verbrauchte kWh werden fehlerhaft, weil die SOC beim Neustart neu berechnet wird.The way this number is calculated is based on the change of the battery state of charge and it's total usable energy. From a displays standpoint we only update the display when the vehicle is running.
Where this may be influenced to a lower than expected value is when there is a battery state of charge correction. While energy is moving into or out of the battery, we use a Battery State Estimation algorithm to determine the State of Charge. Our battery conditioning capabilities in the Volt are engineered to consistently draw the most from our battery while protecting its long term performance capability. After the vehicle rests for a while, we can more accurately determine the state of charge. If that correction causes the state of charge to drop a little bit, that drop will not be accounted for in the kWhs used because the vehicle is not running. This doesn't mean that during that drive you used less of the battery, or the battery's capacity is less, it just shows that there's been corrections in that battery state of charge estimation. Many factors can cause this to happen such as temperature changes and the amount of energy that goes in and out of the pack.. ie mountainous driving.
