Approaching the Spring Festival, many car owners will drive long distances, hundreds of kilometers of high-speed driving at every turn.
There has always been a saying on the Internet that electric vehicles will not work at high speeds, and there is no comparison ...... with fuel vehicles
The main reason is that the advantage of electric vehicles is that they start quickly! But the disadvantages are also obvious, the middle and rear sections are average, and the motor battery cannot adhere to long-term high-speed driving.
Truly!
The electric motor drive response of electric vehicles is indeed better than that of internal combustion engines, and it is said that urban roads start far more than fuel vehicles, and electric vehicles have their unique characteristics of fast torque output, as long as the voltage is in place, 100 milliseconds can output the target torque.
And fuel vehicles, even turbocharged usually exceed 1It takes 5 seconds to reach the ideal target torque, and it takes 200-400 milliseconds to achieve it with natural inhalation.
So judging from the starting action, electric cars are really good!
Generally, fuel vehicles with good power have a top speed of more than 200 per hour, and they can even run faster, and the rear power in acceleration is also abundant.
However, even if the top speed of electric vehicles can be reached, it cannot be maintained for a long time, and even the maximum speed of many electric vehicles is 180 per hour.
The tram's ability to accelerate continuously is very weak.
It is because the torque and power of the tram are realized by the motor speed card number
2 There is an upper limit to the speed of the motor, which is usually around 20,000 rpm.
Limits the ability of the motor to play in the faster speed range!
This one is undeniableIn fact, there are also many electric vehicles that can accelerate in the middle and rear sections, such as Zeekrypton 001, Tesla mod3, and it is no problem to overtake at a speed of 120 to 150 kilometers per hour under normal circumstances.
In terms of China's high-speed legal speed, this speed is enough, and it doesn't make much sense to have a little more, after all, we are not going to the track.
It's a little better in the urban section, after all, the charging piles on the street, even if there is no electricity, can be rescued at any time.
But if this battery anxiety is put to the maximum if it is long and high-speed
One charging is inconvenient, only available in the service area, and I am worried that I can't stick to the next charging pile. And if you accelerate at full speed, the battery level will drop twice.
Therefore, the train generally does not run at top speed, after all, it is good to save a little electricity.
Therefore, the tram can't run fast on the highway, not that the tram doesn't support it, but the driver's rational planning, after all, the success and safe return home is the key!
