Weilai also demonstrated two electric vehicle technologies at the Donghe Trade Show.

Weilai Penguin will release an electric range-extended version of the Penguin in the future.

The range-extended electric vehicle released by Weilai this time is fundamentally different from previous range-extended electric vehicles.

In the past, extended-range electric vehicles had an additional engine and generator installed on the vehicle.

When the power in the car battery is exhausted, the engine starts to start, driving the generator to generate electricity, supporting the operation of the vehicle, and the excess power can be charged into the battery.

However, the extended-range electric vehicle released by Weilai this time has a generator, but it does not have an engine to drive the generator.

So what drives the generator to charge the battery?

When a battery-driven vehicle is running, the power of the running wheels drives the generator to provide power to the battery.

Weilai installed two high-frequency generators on the Penguin's rear axle.

When the battery power of the vehicle itself is less than 40%, the generator and axle are connected to drive the generator to run.

The electricity generated by the high-power generator begins to supply power to the battery to achieve the goal of long-distance battery life.

The power generated by the generator can support the battery to run for 300 kilometers, and the battery itself can run for nearly 300 kilometers, which achieves the goal of 600 kilometers of battery life.

Compared with electric vehicles that use the engine as a range extender, it has the advantage of not burning oil and being quiet.

But there are also disadvantages, that is, when the battery is exhausted and the vehicle cannot move, it will no longer be able to generate electricity.

If the wheels don't turn, there will naturally be no power, and the generator will naturally not be able to generate electricity.

Another disadvantage of this method of extending the range is that it consumes the battery's charge times faster.

The generator often charges the battery, which naturally consumes the number of charging times of the battery.

But this problem is not too big.

The lithium iron phosphate battery currently produced by Weilai has an astonishing number of more than 3,400 recharges. If you only use it for commuting, these recharge times are enough for you to use it for decades.

One charge a day can last you ten years.

One charge every two days can last you twenty years.

If you charge it once a week, you will really have to send everyone away, but the car will still be there.

As for the reduction in battery power, this is basically negligible.

Battery power does not shrink as quickly as people think.

It's about 1.5 to 2 percent per year.

In other words, a battery has been used for ten years and still has 80% of its power.

If you don't run long distances and just travel around the family circle, it is enough.

However, this form of range extension is still not suitable for cold northern regions.

Weilai also launched an engine version of the range extender specifically for northern users.

The vehicle is equipped with a 1.2t 475 gasoline engine and a high-power DC generator. When the battery power is consumed to 20%, the engine starts to work and drives the generator to generate electricity. It runs directly with the electric motor on the vehicle, and the generator emits

The excess electricity can also be reverse-charged into the battery.

It consumes 3.8 liters of fuel per 100 kilometers, but achieves a maximum range of 800 kilometers.

Of course, if you replace it with a 35-liter fuel tank, it will not be a problem to run a thousand kilometers.

Even if it is extremely cold and the battery power is reduced by one-third, you can still achieve more than 500k mileage using the engine.

Compared with those extended-range electric vehicles in the previous generation after 2020, Weilai's technology has far exceeded the level of these car companies in the previous generation in 2020.

The range extenders used by those car companies are basically 1.5t engines, and the fuel consumption is generally around 4.7.

Weilai now uses a 1.2t engine to achieve the effect of their 1.5t engine.

This is technology.

These are two cars that will be released at the end of the year.

However, Weilai did not disclose when these two technologies will be used in electric vehicles.

If it is said to be launched at the end of the year, who would want to buy it?

Naturally, the car owner will wait until the end of the year. Who will sell the current Penguin to?

It is really unrealistic to expect people to spontaneously buy electric cars, so what means should be used?

Jiang Yu remembered that the country used policy measures to promote electric buses.

Since electric buses can be promoted, can the country promote electric taxis?

If the country promotes electric taxis, there will be a minimum demand of 100,000 or 80,000 vehicles in cities of various sizes across the country.

This is a blue ocean.

Jiang Yu found a phone number, thought for a moment and called it.

"Minister Chen! What are you busy with?"

Minister Chen, whom I met at the Shanghai Auto Show a few months ago, now plays a role.

"Mr. Jiang! What else can you be busy with? Besides the electric car thing, how are the sales of your Weilai electric cars?"

"Don't mention it. It has been on the market for two months and only three to four thousand units have been sold. At this rate, the future is not good."

"There are only three to four thousand vehicles, which is really not much. So, Mr. Jiang, what can you do?"

"Minister Chen! Can you remember the country's promotion of electric buses a few years ago?"

Everyone on the phone was silent for a long time.

"You mean you also want the country to adopt policies like electric buses?"

"I think this policy is very good."

"Then what do you think is better to use an electric car for?"

"Minister Chen! What do you think about using electric cars as taxis? This is the best choice to save energy and reduce carbon emissions."

"This is a really good idea, but can your electric car withstand the traffic volume of a taxi? Taxis are different from family cars, and their consumption is very large."

"Minister Chen! Don't worry! There is definitely no problem with our cars, but the country must solve the charging problem as soon as possible. You can't just promote charging cars without setting up charging stations!"

"We were just about to discuss this issue, and we happened to be discussing it with you about the taxi issue. We will try to finalize this matter before the year and start implementing it next year. Oh, that's right! We need to build charging stations. How is your research on impulse equipment?

?』

"Do you need to ask about our charging station technology? How many years have electric buses been used? Our charging station technology is now the most advanced in the world."

"This will be easy to handle. Don't build a charging station when the time comes. You will be dumbfounded if you don't have the equipment."

Jiang Yu put down the phone and was very satisfied. If the country starts to promote electric taxis, this will be a very big order.

As the first domestic company to produce electric vehicles, Weilai will naturally take a large part of this list.

But I definitely won’t eat it all, I’ll definitely leave some for others.

The next thing is to wait patiently.

Weilai Group does not produce the charging piles itself, but leaves it to other companies in Donghe County.

But no matter who makes it, the quality must pass.
Chapter completed!
