The reasons for the false range of new energy vehicles can be summarized as follows:
1. There are differences between testing standards and actual use: idealization of testing conditions: Currently commonly used testing standards such as NEDC, CLTC, etc., the testing process is carried out under specific and ideal conditions, such as turning off non driving load equipment such as air conditioning, headlights, audio, etc., and the testing temperature is controlled within a certain range. The simulated conditions are relatively simple and cannot fully reflect the complex situations in actual road driving. Incomplete testing cycle: The existing testing standard cycle is difficult to cover various scenarios in actual use, such as high-speed driving, rapid acceleration, rapid deceleration, long-term climbing and other special working conditions, which will increase energy consumption and affect the range.
2. Multiple challenges in practical use: Temperature factors: In low-temperature environments, battery activity decreases, electrolyte conductivity deteriorates, battery internal resistance increases, resulting in decreased discharge capacity and reduced range. In high temperature environments, although the battery activity is high, the heat dissipation system and air conditioning cooling will increase energy consumption, which also affects the battery life. Road conditions and driving habits: Congestion on urban roads, undulations on mountainous roads, and wind resistance on highways can all increase energy consumption. Intense driving behaviors such as rapid acceleration and deceleration can also instantly increase the output power of the motor, consuming more electrical energy. Altitude: In high-altitude areas, the air is thin and vehicles need to consume more energy to overcome air resistance, which affects their range.
3. Business strategy of car companies: Promotion strategy: Some car companies may use optimistic data to promote their range in order to gain an advantage in market competition and attract consumers to purchase. This promotional approach may lead to a gap between consumers' expectations of range and actual usage.
The main reasons for the false range of new energy vehicles include differences between testing standards and actual use, multiple challenges in actual use, and the business strategies of car companies. Consumers should fully understand these factors when purchasing new energy vehicles and rationally view the promotional data of range.
