One of the biggest advantages of BEVs is their excellent acceleration. An electric motor with a power of 150 kW can accelerate the car to 100 kilometers in 8 seconds, while an electric motor with a power of 200 kW can accelerate the car to 100 kilometers in 6 seconds. The recently launched ZEEKR 007 model is equipped with an electric motor with a power of up to 310kW, which can be described as full of power.
If it is equipped with a dual-motor four-wheel drive system, the acceleration performance of four-wheel drive electric vehicles is more powerful, and the four-wheel drive Krypton 007 priced at 230,000 yuan only needs 3It can accelerate to 100 kilometers in 8 seconds, which has exceeded the level of million-level fuel vehicles.
BEVs perform particularly well in urban areas, as the internal combustion engine needs to rev more than 2,000 rpm to exert maximum power, while the electric motor can achieve the best power output in an instant, which makes the electric vehicle perform even better in the city. However, BEVs also have significant disadvantages, the most prominent of which are range and power consumption.
Under the domestic CLTC test standard, the endurance completion rate of many models is unsatisfactory, and how to control power consumption has become particularly important. The power consumption per 100 kilometers is a comprehensive indicator, which involves not only the drive consumption, but also the energy consumption of the air conditioning and heating system. Therefore, it is very important to control the power consumption in the overall road conditions.
The energy consumption of electric vehicles of the same size varies greatly, with excellent models achieving 11kWh of power consumption under the CLTC standard, while models with poor control may reach 13kWh or even higher. In daily use, this data gap may expand to about 40%, and for users, the level of power consumption is directly related to the accuracy of mileage and power estimation.
While the acceleration of electric vehicles is excellent, for most users, acceleration in less than 5 seconds is sufficient. Therefore, the product strength of electric vehicles should be reflected in low power consumption, because power consumption directly affects the mileage. The main reason for many models that have been complained by users is that the power consumption is not well controlled, and the CLTC laboratory data is very different from the power consumption in daily use, so the cruising range will also be affected.
Although a car does not have to have a very fast charging speed or the performance of acceleration to 100 kilometers in 5 seconds, it must achieve basic power consumption control. Because power consumption is as important for electric vehicles as it is for fuel vehicles, we pay less attention to power consumption because calculating the cost of electricity is not a matter of urgency, but we are more concerned about the range, and the higher power consumption directly leads to a shorter range.
Therefore, we pursue low power consumption in order to have a longer range and less anxiety, which is also the most basic practical performance of a car.
