Fast Technology reported on December 11 that recently, the winter test activity of understanding Chedi is being held, but after the release of the results of the achievement rate of pure electric battery life in winter, it has caused dissatisfaction among many car companies, and questioned that the test standards of understanding Chedi are not standardized and scientific and rigorous.
Gu Yukun, general manager of the Great Wall Tank brand, issued an article today, also questioning the non-standard winter testing activities of Chedi and the existence of a "greasy" situation.
According to him, in the ice and snow climbing test, the driving behavior of the tank 400 Hi4-T and the evaluation vehicles of the same group was inconsistent during the climbing process: in the acceleration phase, there was a phenomenon of loose throttle, and the speed of the vehicle was reduced from 45km h to 35km h, and then the full throttle climbed.
Before reaching the top of the slope, instead of rushing to the maximum limit like the same group of evaluation vehicles, the braking and stopping operation occurred when the ESP system was normal and the torque was 5400Nm, and the performance of the vehicle could not be fully exerted.
2. In the pure electric endurance test, the tank 400 Hi4-T has 72 minutes of preparation time before the test, during which the door is opened and closed more than a dozen times, and the total time to open the door is about 13 minutes, which increases the energy consumption of the air conditioner, and the total power consumption in this process is 61 degree, the battery life under the converted test condition is 128km。
At the same time, the battery power remains 29At 2%, the throttle depth reaches 84%, the engine starts early, triggering the so-called "test termination condition", the test ends, and 29 remainsThe all-electric range of 2% battery is not included in the overall test results.
In addition, Great Wall Motors also announced today that it will hold a "Communication Meeting on the Questioning of the Winter Test Standards of the Car Emperor" to explain the standards of the winter test of new energy to the public.
