The tram has a range of 1000 kilometers, why are you anxious about running long distances?

Every year when they go home during the Spring Festival, many people run long distances, waiting to see the jokes of the tram, and the last time NIO did a live broadcast, it was Li Bin, the boss of NIO, who personally drove the long distance and ran more than 1,000 kilometers. So why is it that the range of the tram has reached 1000 kilometers, and there is still anxiety, everyone is still waiting to see the jokes of the tram, or do you think that the tram is not good for running long distances?

Over the past year or so, Brother Meow himself has also test-driven a lot of pure electric cars, and has also run long distances, running back and forth from Wuhan to Shanghai.

First of all, the anxiety of running long distances in trams comes from the battery, and the discount on the range of running at high speed is indeed too high. For example, in the live broadcast of Weilai, you will find that the speed of the whole process is only more than 80 and 90, and it is not on 120.

Indeed, if the tram runs at a high speed of 120, then the endurance achievement rate is more than half of the good ones, and some are not so good, such as rain and snow in winter, which may only be forty percent. 1,000 kilometers may be only 500 kilometers. Of course, 500 kilometers is indeed not short, for many fuel trucks, the fuel tank is a little smaller and will run 500 kilometers.

But the second problem is that the relative replenishment of oil trucks is relatively fast. When I entered the gas station, I filled a tank of fuel in 3 minutes, and continued to run after filling it up.

But tram charging, how to say slower than oil cars, although this year there is 800 volt fast charging, but according to Brother Meow's own experience of running high speed and long distances, 800 volt fast charging in many places, in fact, can not play an effect.

Because in the high-speed service area, many of them are charging piles of the State Grid, many of them are 60 kilowatt charging piles, and some of them are 120 kilowatts, but they are not popular. Then even if your car supports 800-volt fast charging, the charging pile can't keep up, so the charging is also slow.

Third, it is the problem of the occupancy rate of charging piles. Usually run well, there are not so many trams on the highway, and many places on the charging pile are empty, but when it comes to holidays, there are many cars on the highway, and the occupancy rate of the charging pile is high.

And Brother Meow found that when many drivers go to charge, they just feel that they need to charge to 100% full, but the fast charging range of most trams is 20% to 80%, more than 80%, and the charging power is all down, especially after 90%, trickle charging is slower.

It may take half an hour to charge from 20% to 80% in the front, but it may take 50 minutes or even an hour to charge from 80% to 100%, and the time cost has greatly increased.

But many drivers feel that they are going to be full, at this time for the charging pile to occupy a long time, originally a service area may have four piles, if everyone does this, then the car behind can not be charged, resulting in a long queue.

So in the event of a holiday, I suggest that if you drive the tram back, then you charge it to 80%, use up the fast charging section and quickly withdraw, vacate the position for the car behind you, and wait until there is a vacancy in the next service area, and then charge it with you.

If everyone can do this when driving a tram, then the efficiency of the charging pile will be greatly improved during the holidays. If you have to charge 100% of the pile, then everyone's charging efficiency will be seriously reduced.

Fourth, anxiety about traffic jams. Because we usually encounter traffic jams on oil trucks, if the jam is very long, it is very cold and you can't stand it, so you need to turn on the air conditioner.

For example, a petrol car uses an engine to heat up, and an electric car actually uses a battery to heat up. Although they are all heated, it seems that the anxiety of the tram will be greater, like the parking of the tram for heating, which may basically reach more than 2,000 kilowatts to 3,000 kilowatts of power, and it will take more than 20 to 30 kilowatts of electricity in 10 hours.

The oil truck uses one liter of oil per hour, and more than a dozen liters of oil are used in 10 hours, but in the same way, if it is opened to traffic, when everyone has no electricity and no oil, if there is a rescue, the oil truck is filled quickly, but even if the tram has rescue, the charging time is much slower.

summary

Although the tram is now claimed to have a range of more than 1,000 kilometers, due to the actual car environment and the influence of the charging environment, compared with the oil car, there is still anxiety when there are many cars on the festival, especially when the weather is cold.

Anxiety comes more from uncontrollable factors such as road conditions and charging, so if you drive a pure electric car for a long distance during the holidays, you really need to plan well in advance, of course, hybrid vehicles do not have this anxiety.
