Recently, the old friend and my big spoys, saying that now, the endless life of the pure tram type is seriously dasual, causing him to abandon the high speed, after 4S shop, 4S shop also said that all kinds of tests are very normal. He believes that the 4S shop is definitely in shocking responsibility.
I listened to the whole thing, although I had a deep sympathy against him, but I have to tell him the truth. It is a factory, not the manufacturer’s virtual standard, but He will dig himself.
It is necessary to reproduce his story, because this situation is a lot of pure tram type owners experience, understanding the true situation, Avoid you to dig your own.
This is a misunderstanding, and the old friend is going to go to the city to send people, the destination is around 80 kilometers away from the departure location, while the old friend’s pure tram model shows, 200 kilometers of the battery life.
Old friend is a 10-year fuel car, and the vehicle will save energy at high speed when running high speed. This can run a round, then Put it in the company’s downstairs, don’t delay.
The whole process of giving people is no problem. When it comes back, when the old friend discovers the battery life, it has been less than 80 kilometers, and the lighting mileage is very fast, not yet To the middle, there is a remaining 20 kilometers, and I am afraid to enter a gas station, but also a charging pile, this is a shocking and dangerous spent “a robbery.”
Old friend said, if you know that pure tram type is so serious, you will make him “distress” in high speed, he will definitely change its own fuel car to run high speed. 
Don’t say that old friends’ pure tram type is a brand, so as not to cause unnecessary negative impacts to the brand. In fact, all pure tram type running high speed is encountered.
In fact, the manufacturer is virtual standard life, and it is impossible to judge through this matter. The reason is that the old friend gives himself a pit. It is because he uses the wrong experience.
For fuel vehicles, driving in the urban area, due to frequent parking and start, and energy consuming, it is more cost-effective than running high speed, while driving on the highway, due to moving, small brakes, and internal combustion engine The work efficiency change, it is more economical, so many fuel-fuel drivers open the pure tram type, there is a mistake experience, think that the pure tram runs at the same energy, the actual battery life, should be marked than in the city The battery life is longer.
But the fact is that it is exactly the opposite.
Pure tram type running high speed, will be more expensive, the actual battery life, which is much reduced more than driving in the urban area, is determined by the working principle of pure tram type. 
In the urban area, although there is more traffic light, the parking is frequent, but the electric car is idling at the traffic jam, although the motor is still in power-on, but if the control pedal does not step on the door, the motor will not work. The energy of the motor loss does not work is basically negligible.
That is, the vehicle caused by traffic jams in the urban area will start, stop, will not bring greater power consumption, the labeling of the life, and it will be quiz, according to their own battery life. It is more reliable.
But the high speed is not the same, the speed increases, the wind resistance has rapidly increased the speed of the vehicle, the vehicle maintains a high speed, and it needs to overcome the wind resistance, the higher the speed. The larger the wind resistance, so the higher the speed, the higher the power consumption, the more the life is dropped.
Moreover, the motor does not have a high speed, and the power consumption is high, but after a critical point, the electricity consumption will increase vigorously, this is not a problem of which motor, and almost All high-speed motors, this is also a common problem of all electric vehicle motors.
This shows that the experience of the old driver before, in electric cars, is not applicable, relying on this experience to run high speed, do not leave anchor, this can’t blame the vehicle itself. 
This is a solution
After the old friend asks, how does this judge, there is no formula, it can be judged, the high-speed and the cityThe life ratio of travel within the district.
This is really unable to solve, because the wind speed is different on the day, the top wind is not necessarily, the road condition is different, and each driver control has different speeds, and each brand motor is also different. It is very judging at high speed. How much can I have on the endless mileage.
What is it?
One is that if you travel, and you don’t understand the charging station layout along the way, it is recommended that you still have a fuel vehicle, after all, the gas station is everywhere.
Even with the high speed of the road, it is best to find a good charging station before departure, to ensure that you will not leave on the high speed, nothing more than a point of charge of charging.
The working principle of electric vehicles is different from the fuel truck, many experiences used in the fuel truck, not suitable for electric vehicles, don’t dig your own Pit itself.
