What is the conversion ratio between NEDC range and actual mileage?
2 Answers
NEDC range is approximately 20% higher than the actual mileage. Here are the relevant details: 1. NEDC: NEDC stands for "New European Driving Cycle", which is the "New Standard European Cycle Test". The Chinese Ministry of Industry and Information Technology adopts the NEDC test standard when evaluating the comprehensive range of pure electric vehicles. The NEDC test cycle includes 4 urban cycles and 1 suburban cycle (simulated), with lower speeds in urban cycles and relatively higher speeds in suburban cycles. 2. Precautions: Before driving a pure electric vehicle, it is essential to check the remaining battery capacity to ensure sufficient driving range.
In my years of driving electric vehicles, I've found that the NEDC-rated range is just a reference value, and the actual driving range is typically only 70% to 80% of it. For example, if a car's NEDC shows 500 kilometers, the real-world range often falls between 350 to 400 kilometers. This gap comes from real-world conditions, like frequent stops and starts in city traffic during my daily commute, which drains the battery faster. Running the AC in summer or cold starts in winter also spikes power demand, easily reducing range by 20%. High-speed cruising with high wind resistance consumes more energy too, unlike slower speeds which are more efficient. For an accurate estimate, I'd advise owners to test it themselves: fully charge the battery, drive a normal route, record the dashboard data, and calculate the average. Regular battery maintenance is also crucial to prevent accelerated aging and range loss.
