What does NEDC comprehensive range mean?

NEDC range stands for New European Driving Cycle, and here is some relevant information: 1. NEDC range refers to the New European Driving Cycle, which is Europe's range testing standard. When China's Ministry of Industry and Information Technology tests the comprehensive range of pure electric vehicles, it adopts the NEDC testing standard. 2. During NEDC testing, the vehicle is placed on a test bench. Although it can also be conducted on a windless flat road, to simulate various situations encountered during actual driving, the rollers in contact with the tires are equipped with motors to simulate resistance under different driving conditions. The test includes two driving conditions. The first is the urban driving cycle, which simulates urban driving conditions from 0 to 780 seconds, involving repeated cycles of acceleration, maintaining speed, deceleration, and stopping, performed four times. Starting from the 780th second, the second driving condition, the suburban driving cycle, is tested, where the vehicle speed is significantly faster than in the urban driving cycle.
As a regular driver who frequently uses electric vehicles, I think the NEDC combined range is just a rough estimate provided by manufacturers under ideal testing conditions. It simulates urban and highway driving in a lab to calculate an optimistic figure. In real-world usage, factors like using air conditioning, sudden acceleration, or extreme temperatures can reduce the actual range to about 70-80% of the advertised value. I consider this data when choosing a car, but I trust my own test-drive experience or friends' feedback more, since advertisements often exaggerate. A longer range means fewer stops to charge, which is convenient for long trips, but it's not an absolutely reliable standard. Nowadays, many cars boast high ranges but overlook real-world scenarios, so I always estimate conservatively to avoid running out of power mid-journey.
From the perspective of automotive technology enthusiasts, NEDC is an outdated European testing protocol that uses standardized driving cycles to estimate battery range, including modes like startup, acceleration, and constant speed. However, it's overly laboratory-based, ignoring real-world factors such as wind speed and tire pressure, resulting in over 20% deviation from actual results. I'm more interested in newer standards like WLTP, which better reflects real driving conditions with significantly higher accuracy. Understanding NEDC helps interpret advertised data, but actual performance should be assessed by combining vehicle energy consumption curves with user reports. When choosing an electric vehicle, don't rely solely on this number – battery quality and driving habits have greater impact, as frequent hard braking or fast charging can drastically reduce range.
