The difference between the actual mileage of electric vehicles and the manufacturer's publicity has always been the focus of consumers' attention. Many users have found that although manufacturers claim that electric vehicles can travel 80 kilometers, they can often only reach 0 kilometers in actual use, and they shrink to about 0 kilometers in winter. Exploring the reasons behind this gap can be summarized in the following five points.

First of all, the actual riding conditions are very different from the manufacturer's test environment. Frequent stops at traffic lights, acceleration overtaking, climbing and other actions during riding will significantly increase energy consumption and thus reduce the cruising range. The operating temperature of the battery is also a key factor, and as the temperature drops, the battery performance is also affected, resulting in reduced battery life. In addition, the load of electric vehicles cannot be ignored, and for every 18 kg of load, the range may be reduced by 0% to 0%.

The dynamic attenuation of the battery itself is also an important factor affecting the battery life. With the passage of time and the increase in use, the battery capacity gradually decreases, and even with the right charging method, this natural process of attrition cannot be avoided. As a result, EVs have a good range at the beginning of their purchase, but tend to decline significantly after half a year.

The owner's riding habits also have a significant impact on the range. Different car owners have different riding styles, some tend to drive at high speeds and brake frequently, while others focus on economic mode and maintain a constant speed. Obviously, the latter riding style is more conducive to improving the range. Factors such as tire pressure and the weight of the owner cannot be ignored, which will affect the resistance of the electric vehicle to a certain extent, and then affect the range.

The riding environment and road conditions also have a significant impact on the range. In actual riding, it is inevitable to encounter uphill and downhill sections, and the battery life may even be only about 50% of the theoretical value when continuously going uphill and downhill. At the same time, the wind factor should not be underestimated, with headwinds or crosswinds reducing range, while tailwinds can help improve range. Road conditions are also one of the key factors affecting range, and dry roads are more conducive to improving battery life than wet roads.

It is important to note that the range advertised by the manufacturer is usually the theoretical maximum, not the average value in actual use. According to the new national standard, the range of electric vehicles is allowed to have a margin of error of 10%. Therefore, manufacturers often choose to mark the maximum range to attract consumers. However, this often leads to disappointment among consumers in actual use, because there is a large gap between the actual battery life and the advertised data. In the face of this situation, many consumers call on manufacturers to mark the cruising range more realistically to avoid misleading consumers.

There are various reasons for the difference between the actual mileage of electric vehicles and the manufacturer's publicity, including riding conditions, battery attenuation, riding habits, riding environment and road conditions, and manufacturers' publicity strategies. Therefore, consumers should look at the promotional data rationally when buying electric vehicles and make choices based on their actual needs.
