The so-called electric vehicle with another hybrid concept, the concept of extended-range electric vehicle, is actually to load a diesel engine or gasoline engine on the vehicle. However, the function of this diesel engine or gasoline engine is not to drive the vehicle, but to provide power to the front.

The electric motor is charged, and then the electric motor is used to drive the vehicle."《》"

This approach will make the car's fuel consumption very low and also reduce emissions, because generally the horsepower and displacement of the gasoline and diesel engines used in such extended-range electric vehicles are quite small.

In this way, the goals of energy conservation, emission reduction, and cost savings are achieved, but such a car is not without its shortcomings.

The biggest disadvantage of this extended-range electric vehicle is that its horsepower is relatively weak and the linear output of the vehicle is not good.

Vehicle-mounted electric motors often have a weakness, that is, they have low power but high torque. This makes the car's speed-up performance better, but when the speed reaches a certain peak, it will be difficult to speed up. This is also the case with general hybrids.

The main reason is that when a car is driven by an electric motor alone, it is difficult to reach a speed of more than 100 yards.

This kind of car is sufficient for driving in urban areas, but if it has to face more complicated road conditions, it may be a little overwhelmed.

For example, when you drive on a slope or a road with many curves, the car's linear output will not be very good, and the vehicle speed will often appear to be slow.

Or when there are people on board or the load is large, the speed will not be able to increase, etc.

But when this idea is merged with hybrid vehicles, it will become extremely powerful. Everyone knows that in current hybrid vehicles, the main way to charge the battery is to recover kinetic energy during braking.

Moreover, in the current year of 2005, the method of plugging in to charge the car has not been widely promoted, so even Toyota, which has been making hybrid vehicles for the longest time, has difficulty in solving the problem of charging the Prius.

It is difficult to fully charge the car's battery just by recuperating the car's braking kinetic energy and charging the battery at high speeds of over 100 kilometers per hour.

After all, not all car owners go on the highway every day, so the Prius will also face the problem of frequent low battery power.

In the following years, in order to solve such problems, the third-generation Prius directly launched a third mode of plug-in charging to charge the car.

Some other manufacturers that have recently joined the hybrid car group are also trying their best to solve this problem. However, in the end, most of their methods are the same as the Prius, choosing to add an external charging port to the car.

Charge the car.

But this method is not perfect. You must know that at that time, there were not many countries in the world that had charging stations dedicated to charging hybrid vehicles on the roadside.

Moreover, the charging time will also be different due to voltage and other issues, resulting in different charging time and other problems.

Someone once thought of a way to quickly replace the battery of an electric vehicle, but in the end this idea was just a flash in the pan, and nothing was done. After all, the cost of doing so was too high.

But in 2011, Chevrolet launched a Volt model, which was a holographic vehicle that enhanced the performance of electric vehicles.

They equipped the car with an internal combustion engine, but the main function of this internal combustion engine is not to intervene in the driving work of the car. Instead, when the car's battery power is less than 30%, this internal combustion engine will intervene.

Then the generator is driven, part of the power is involved in driving the car, and the other part directly charges the battery.

When this car first came out, the data released shocked Jin Xiaoqiang. The car's maximum range in electric drive mode could actually reach 527.5 kilometers, far exceeding the Prius.

The pure electric drive mode has a distance of more than 20 kilometers in the third generation.

But the data released later on this car also surprised Jin Xiaoqiang. The price of more than 500,000 yuan, and the car's fuel consumption of 6.3 liters per 100 kilometers, made Jin Xiaoqiang feel that this car was really a scam.

of.

Aren't you kidding me?

With such high fuel consumption and such a high selling price, what’s the point of your so-called new energy vehicle?

It’s no wonder that after this car was launched by Chevrolet, few units were sold at all. Anyone who bought this car would have had their brains kicked by the donkey for choosing such a crappy car.

The most expensive part of Chevrolet's system is undoubtedly the planetary gear system inside. It is this system that causes the cost of the entire vehicle to be ridiculously high. But if such a system is abandoned, it will simply

It is not impossible to make an extended-range electric vehicle.

For example, later at the 2012 Beijing Auto Show, China Automobile launched a concept version of an extended-range power vehicle.

The entire vehicle omits this complex planetary gear system, and only has an inverter to replace the role of the planetary gears, which can solve this problem very well.

In this way, the cost of the entire vehicle will be greatly reduced, and the model will be reduced to a pure electric vehicle.

The vehicle does not have a particularly big advantage in terms of speed-up and sports performance. The key lies in fuel saving and energy saving. The 0.9L dual-cylinder internal combustion engine configuration and the electric driving distance of more than 300 kilometers are the highlights.

Although China only launched a concept car at that time, Jin Xiaoqiang felt that if the advantages of this car could be carried forward, then this car would still have a huge market in China.

After all, most of the current car consumers in China are ordinary people, not all of them are rich, and everyone still cares about fuel consumption.

Moreover, the new generation of consumers, especially the ordinary family car consumers born in the 1970s and 1980s, is not unable to accept the concept of hybrid vehicles. It is just that the price and subsequent maintenance costs of hybrid vehicles are too expensive, so everyone

That's why I'm so shy about such a car.

If I could install such an extended-range drive system on a small car like the QQ, then the driving power provided by the 0.9L internal combustion engine might provide even better performance.

And once such a model enters the low-end model market at an ultra-low price, it may immediately set off a big storm.

You must know that the Ricky QQ, which is very popular in China, is a small-displacement car. The fuel consumption in urban areas is generally about 6.5 liters, and it is also 4.5 on suburban highways. In total, the fuel consumption per 100 kilometers is about 6.5 liters.

About 5 liters.

However, generally people who drive this kind of car still drive more in urban areas. If the fuel consumption of such a small electric car can be made less than or close to this average value, then in Jin Xiaoqiang’s view, such a model

There is still a lot to be done.

Even though the price is slightly higher than that of QQ, it has an incomparable advantage in terms of fuel consumption, and the most important thing is in terms of workmanship and silence. This kind of car has incomparable advantages over cars like QQ.

, if we give this car a perfect appearance, I believe there is still a lot to be done in PK and QQ.

Thinking of this, Jin Xiaoqiang couldn't help but start to get a little excited. Of course, this is only the most preliminary stage and is also the market cultivation stage.

As long as a certain number of consumers who are interested in hybrid vehicles are cultivated within this range, there will be a certain source of customers in the future.

I believe that these consumers, after their economic capabilities improve, will also be interested in the more high-end hybrid models that Huayang Power will launch later.

In fact, Jin Xiaoqiang also has his own thoughts about subsequent higher-level hybrid models. In his opinion, concepts like the Prius will become a mainstream hybrid model in the future.

Gas-electric hybrid drive will be the king of hybrid vehicles in the next ten years.

Especially the hot sales of the third-generation Prius and Prius C models have given Jin Xiaoqiang a clear direction in his mind. Toyota is just pushing the Toyota Prius to the second generation.

Their third-generation product will not be launched until 2009, and the Prius C, which uses lithium batteries, will not be launched until 2012, when lithium battery technology is relatively mature.

This gave me a lot of time to imitate their system. The entire Prius system is actually not complicated, but the most critical thing is of course the battery installed in the car.

The operating mileage that the on-board battery can guarantee in pure electric mode will be the key to future hybrid vehicles.

It seems that after returning home, we will have to work more on the lithium batteries studied by Binxin WeChat.

Compared with the nickel-metal hydride batteries currently used in hybrid vehicles, lithium batteries have advantages such as faster charging, no memory effect, more power, longer cycle life, and easier shaping.

Therefore, generally after 2012, new models entering the hybrid vehicle market generally use emerging lithium batteries.

Jin Xiaoqiang thought about it. If he remembered correctly, next year, in 2006, the world's largest electric hand tool company, Black & Decker, will launch a powerful electric hand tool. Once it is launched, it will be popular among consumers.

Popular.

The reason why this electric hand tool bag is so popular is because it uses lithium iron hydrochloride battery, which ensures that the battery function is more powerful.

This has ushered in a great era of lithium batteries. Starting next year, major energy companies in the world will increase their investment in research and development of lithium batteries.

It seems that we need to get some technically mature lithium batteries out as soon as possible, so that we can make better hybrid cars and compete with the Prius for the market!
