As we all know, a pure electric vehicle parameters are constant mileage, mileage and constant velocity, by definition, that is, on the temperature, load and other variables under the control of the vehicle at a speed of 60plusmn; 2 km per hour constant speed that can travel the longest distance. So, if you are traveling across town, under constant Mileage reach the finish line faster; or reach the end of the middle charge faster?
To address this issue, we still need to make an assumption. For example, the test vehicle needs to be cross-town trip of about 480 kilometers, while the maximum endurance test vehicle odometer now 500 kilometers, in accordance then travel 60 km / h, 8 hours before they can reach the end. 
If the test vehicles with intermediate charging mode, according to the maximum speed of 120 km / h is calculated 4 hours to reach the end.
However, in consideration of the electric vehicle when traveling at high speed, power consumption will be faster, but can not keep the vehicle 120 km / h, together with the charge time, the high speed estimated vehicle reaches the end of time spent in about five hours, will still be faster than under constant conditions.
Therefore, under normal circumstances Cross City trip, take the vehicle at high speed midway charging way, will reach the finish line faster than the constant speed.
