Questions about electric vehicles Questions about electricity for battery cars?

According to the national electric vehicle ranking, the first place is Xinri; second place went to Yadea; The third place is Oupai.

Of course, Yadea's cars are expensive, as long as the ampere number of 36V and 48V is the same, there is not much difference in technical parameters and durability.

The ordinary simple model sells 1700, which is also low in the simple electric car model, and our Yadea electric car in Yunnan is not less than 2000 yuan.

If you are in true love, I am afraid you have to think carefully, he belongs to a pure third-tier brand, and even the spokesperson is a third-tier star. The quality is not as good as Yadea, and the ** aspect is not as high as Yadea. There is no problem with riding, mainly after-sales service.

I think you still choose the best 48V, now the price of the 36V electric car 1700 is too high, and it is almost eliminated, and it is estimated that the ones sold now are in stock. It's that I sell electric cars, and I don't sell the style you said, but I have a 48V little flying fish (similar to a small bee sample test) The empty car purchase price is 1280 yuan, plus Tianneng battery 48V 390 yuan, plus the charger about 30 yuan, a total of 1700, but if someone gives about 1850, I can sell it. Yadea, the new day is OK (top ten brand electric vehicles), who is better depends on how you use it.

In my Sichuan side, Yadea sells well, but the customers are not too satisfied.

My family is a rainbow cat, it's not good at all, I can't run! Don't buy it, I highly recommend Giant, I only recommend used, tested, true love is OK, I haven't used it on the new day, I don't know

The battery needs to buy a special battery, and the batteries that the local dealers have are generally cheap batteries.

A well-serviced electric car is the best electric car.

Despise all Tianjin brands flickering! Shoddy! There is no strength to rely on appearances alone!

It's better to choose Chinese famous brand products. You get what you pay for.

Personally, I think the new day is a little better, the brand!

It can't be counted that way.

1 It depends on whether your road is asphalt road, water old mud road, dirt road and other ground conditions, as well as whether it is a mountain road or a flat road.

2 Look at your load, that is, how much weight the person your bike pulls.

3 Look at how many blocks you drive on the road, the faster the speed, the higher the electricity.

4 Look at how high the temperature is when you are on the road, the temperature is 28 degrees Celsius and the temperature is 15 degrees, and the temperature is minus seven or eight degrees Celsius, which also has a greater impact on the battery.

5 It depends on whether you have a good wind or a bad wind.

6 Some electricity in the battery cannot be used, such as about 5-10% left, you need to consider charging, at this time, even if you fill the gas pedal, the car will not run fast, so Lu Han's lack of these electricity can not be counted.

Theoretically, it can be calculated as 69 100 = 690 meters in the early days), that is, 690 meters can be driven for every 1 percent of the sales, and 56 can be driven 56 kilometers at a loss.

One hundred percent electricity per kilometer!

If it is a new tram battery, you have a problem with the electric car or the battery has a problem, under normal circumstances, a fully charged electric car, every one or two months, the electric car still has a lot of electricity, 1 unless you return to the motor car before the state of change the crack power loss is your problem.

2. The battery is leaking and full, the electric vehicle lock is closed, the controller steals electricity, and the electric vehicle is problematic.

3. The battery itself loses power, the battery is a problem, or the old battery.

This cannot be accurately calculated, but only empirically to see how many kilometers can be run with the remaining electric core, because the first 30% of the battery is durable, the middle is linear, and the last 30% is powered off quickly.

Because the voltage is low in the later stage, to ensure sufficient power, the current will become larger, and the active efficiency will be reduced.

Generally, the new motor manufacturers will use relatively poor motors! Naturally not as good as the original, the original motors are strictly inspected, the motor you replace belongs to the after-sales motor, naturally a little worse, but the power consumption is only one of them,,Hehe。。

1. The power consumption of the motor is large, which means that the current of your motor's riding limbs is large, which means that the motor that changes the slag is not good.

2. It is also possible that the motor is not installed properly, and the motor is not parallel to the frame. Or the motor is not on the same centerline as the front wheels.

The battery car is indeed economical, practical and convenient. However, the jujube fiber bottle car must ensure that the battery power is sufficient. Only the stool guesses the imitation can ensure the use of the car. It's okay to have high temperatures in summer. In winter, the temperature is low, and the battery car is early in the morning, and the mileage is short. Keep charging frequently.

Turning off battery cars is more economical and much cheaper than gasoline cars. So as for the question of how much electricity he uses, this is not very important, as long as you charge him in time when you don't use it every day. Only charging, even if this battery is highly buried, only for a long time.

The so-called homemade battery is actually the assembly of the battery, including the shell. plates, glue. electrolyte and much more.

Personally, I think that buying an electric car has the following questions, and there are several major questions that you must face:

1. Power anxiety;

2. Fast update and iteration;

3. Highly integrated.

Today, let's talk about battery anxiety (range anxiety). Is the problem of battery life prominent? Charging too long?

In fact, I don't think the main shortcoming of electric vehicles is that range. At present, most of the mainstream electric vehicles on the market can have an actual range of more than 400km. When driving long distances, the average person can't withstand 400km continuous driving, which means that the high-speed 120km h continuous driving is close to 4 hours (crazy calculation).

Tesla passengers said that with this ride experience, I would like to get out of the car and rest in less than three hours. Ask yourself: Can you drive for so long? Therefore, the problem of battery life is particularly prominent.

The solution of major manufacturers is to develop new battery technology or enhance battery life. Obviously, enhanced re-battery life is a relatively easy solution to achieve, just match the charging infrastructure and add fast charging capabilities. Therefore, major manufacturers have shown their magic and given many fast charging schemes, but it still takes more time to charge than to refuel.

When driving long distances, it doesn't even take enough time for a fuel car to get back to the toilet. And the electric car can last a few more years, probably need to eat, go to the toilet, and then rest for ten minutes. If you think about it from another angle, this invisibly adds points to road traffic safety (Road Traffic Safety Law - long-distance driving requires rest).

Developing a new battery technology is the most challenging? Since fast charging is an immediate solution, even manufacturers developing new battery technologies have to follow suit, otherwise they will not be able to keep up. Of course, there are also manufacturers that do not keep up with the rhythm of the market (Hongguang miniev:

I suspect you're connotating me). When it comes to battery technology, that has to be mentioned"Big guy"BYD. When you think of BYD, what comes to mind?

Masks, Dynasty series, battery technology ......That's right, it was the world's No. 1 mask manufacturer, the pioneer of the Dynasty series, and the first-class on-board battery technology. After all, BYD has mastered the core technology, so BYD's electric vehicles not only have fast charging, but also will apply the latest battery technology to ensure the three inputs of charging piles, fast charging and batteries. Of course, there is also the issue of battery safety, which is also of great concern to BYD.

What should I do if my range is reduced in winter? There is another question: electric vehicle users in the north should have a deep experience, that is, the range of 500km in winter becomes 250km?

That is, it is often referred to as the problem of electricity loss in winter. In fact, it should not be called a false standard of power, because whether it is a lithium battery or a lead-acid battery, it is a problem of battery activity.

It doesn't matter if you don't get angry. If you don't know how to ride an electric car, you can choose other ways of travel according to your living standards, such as green and low-carbon environmental protection travel: walking, taking buses, sharing bicycles, or you can call online car-hailing if the conditions are better, and taxis are also very convenient.

Learn simple tricks for electric vehiclesFirst of all, find a spacious place without people and cars, start to learn to ride a battery car, turn off the electricity, sit on the car, land on both feet, push the car for two hours, do this step to get familiar with the car, turn on the electricity, drive along a straight line, turn to the end, slow down when turning, continue to drive straight, drive around the four sides, slow down every corner, get on the road, wear a helmet, and keep right. Go to the left and hit the left direction light, go to the right and hit the right direction light, and ride more, the more courage you will have, and you will ride.
