For new energy vehicles, the test standards for their range will also affect the final range value displayed.
The method of calculating range depends largely on the type of vehicle and the energy source used. Below are some common scenarios of how range is calculated:
Fuel vehicles or motorcycles
● Range = (fuel capacity / fuel consumption) × maximum speed. Where fuel capacity is the capacity of the fuel tank (in liters), fuel consumption is the amount of fuel consumed per 100 kilometers (in liters), and maximum speed is the maximum speed (in kilometers per hour) that the vehicle can reach at high speed.
Electric bicycles or motorized vehicles
● Range = Battery voltage (V) × Battery capacity (Ah) × Speed (KM/H) ÷ Motor power (W).
● Another simplified calculation method is: theoretical range = battery capacity × 3 (e.g.: 48v20ah theoretical range is 20 × 3 = 60km).
It should be noted that the above formulas are based on the estimated value of ideal conditions, the actual range will be affected by a variety of factors, such as road conditions, temperature, load, driving habits and so on.
In addition, for new energy vehicles, the range test standards will also affect the final range value displayed. Currently, there are common range standards such as WLTC, NEDC and CLTC, etc., and the range figures measured by them may differ. Generally speaking, the numbers measured under the WLTC standard are relatively more realistic, while the numbers measured under the CLTC standard may be more false. Therefore, these factors need to be taken into account when comparing the range of different vehicles.
