What is the most indispensable thing for pure electric models?
A motor with a power of 150kw can make the vehicle accelerate within 8 seconds (yuan plus), and a motor with a power of 200kw can ensure the acceleration of the vehicle within 6 seconds.
The recently launched ZEEKR 007 directly gave a motor with a power of 310kw, and the front power was even more terrifying.
If it is directly equipped with a two-axle motor, the acceleration performance of a four-wheel drive electric vehicle is even more terrifying, 230,000 bought four-wheel drive Krypton 007,3Breaking 100 in 8 seconds, this is already a height that is difficult for fuel vehicles within one million to reach.
Trams actually run fast, especially in urban areas.
Because the power of the internal combustion engine is in the middle and rear sections, at least after 2000 rpm, the real strength of the internal combustion engine can be exerted, but the motor can reach the best power in an instant, and the "instant maximum torque" characteristic brings a very terrifying initial acceleration ability.
In urban areas, the speed of this car can not reach 80km h, which is definitely the world of motors.
Pure electric models are products with very obvious strengths and weaknesses, and fast acceleration is their characteristic, but the same problem is also very obvious, that is, the power consumption problem that many companies will not mention.
In itself, electric vehicles have a serious problem of battery life collapse, a comprehensive road conditions can reach 80% of the battery life completion rate of the model is already very good, according to the domestic CLTC test standards, many models of the battery life completion rate is not high.
Therefore, how to control power consumption is very important.
100 kilometers of power consumption is a comprehensive index, not only drive consumption, air conditioning and heating consumption is not small, how to control the power consumption under comprehensive road conditions, in fact, is very important.
The difference in energy consumption between trams of the same size is actually very large.
Excellent trams can make 11kWh of power consumption under the CLTC standard, but if the control of power consumption is not good enough, the power consumption of 100 kilometers can reach 13kWh, and this data gap can be widened to about 40% due to the difference in the intensity of daily use.
That is to say, some cars can achieve 14kwh of power consumption per 100 kilometers for daily use, and 20kwh for 100 kilometers of poorly controlled cars.
Compared with performance, it is obvious that we need products with low power consumption, after all, the power carried by the battery pack is fixed, and the lower actual power consumption will ensure longer battery life and more accurate power estimation data.
After all, in daily household situations, 8 seconds of acceleration is actually enough, in most cases, the acceleration ability within 5 seconds is redundant, the tram is a barrel effect piled up of products, power consumption is often an important factor limiting the reputation of the vehicle.
There are a large number of models in the market that have been complained by users about false standards, the main reason is that the power consumption is not good, and the gap between CLTC's laboratory data and daily use is huge.
If the power consumption is not done well, the battery life under daily use will definitely collapse.
The logic is that the battery life displayed on the dashboard is calculated according to the full power and CLTC power consumption standards, but the power consumption during daily use must be higher, so the battery life must be inaccurate.
A car can not have a very fast charging speed, nor can it need the so-called 5 seconds of acceleration, but we must do the most basic power consumption, because power consumption is like the fuel consumption of fuel vehicles, and we are sensitive to fuel consumption in the era of fuel vehicles because of high oil prices.
The reason why we are not sensitive to power consumption in the era of electric cars is because it is unnecessary to calculate the cost of electricity, but we are more worried about battery life, in fact, short battery life is a direct problem caused by high power consumption.
In other words, we demand low power consumption in order to pursue long battery life and no anxiety, which is the most basic product power of a car.
