AutoBeta(AutoBeta.net)08/16 Report--

The topic about whether the backwardness of add-on electric technology will be eliminated has been controversial in the industry for a long time. Recently, a number of car company bosses have also expressed their views on extended range hybrid technology in public.

He Xiaopeng, CEO of Xiaopeng Automobile, said at a press conference on August 15 that ultra-fast charging will lead to an explosion of pure tram sales of more than 200000 yuan. With the development of ultra-fast charging technology, fuel vehicles below 100000 yuan will be quickly replaced by pure trams; fuel vehicles in the range of 100000-200000 yuan will be impacted by hybrid and pure electric models, and the hybrid performance will be more prominent; if more than 200000 yuan, pure electric models will be stronger.

On the same day, ideal car CEO Li also said at the Q2 performance meeting in response to everyone's doubts about the add-on technology: looking back five years, the add-on is still the best solution for SUV, and the ideal thing to do is to continuously improve the efficiency of the add-on. In the long run, extended range is the best solution for SUV. It points out that the add-on is an electric car, with an augmented range, and the PHEV is a fuel car with a battery. There is an essential difference. If this is not clear, I do not believe that they can make a good product. "extended range" means "increased mileage". An electric vehicle with a fuel engine on the basis of a pure electric vehicle uses the engine to generate electricity and recharge the battery when the battery is low. It is worth noting that the engine of the add-on electric vehicle does not participate in direct drive, and there is no fuel-driven mechanism such as clutch, gearbox and so on.

And there is also Huawei Yu Chengdong who is optimistic about the add-on hybrid technology. Earlier, it was pointed out that "at present, the improvement and popularization of charging piles still take time, and the extended range mode is the most suitable new energy vehicle mode at present." Extended range is very suitable as the first car in the family. It is suggested that pure fuel vehicles should be eliminated as soon as possible. It is also said that gasoline power generation for extended range vehicles is more fuel-efficient than fuel-fueled cars, which can save about half of the fuel and really bring about an improvement in energy efficiency.

Of course, some people support and others hold different attitudes. Tesla CEO Musk commented on the social platform earlier: hybrid cars are only a short stage of car development, and now is the time to give up hybrid cars. Feng Sihan, CEO of Volkswagen China, said: add-on electric cars may not be as environmentally friendly as imagined, and from the point of view of the whole country and the earth, using the combustion of fossil fuels to generate electricity for the car power system is a "bad solution". At the same time, Weidman, head of the R & D department of Volkswagen Group, also said that add-on is an outdated technology and has little potential for development. Li Ruifeng, CEO of Great Wall Wei Brand, even wrote many times on the social platform that "it takes good blacksmiths to make good steel. It is an industry consensus that add-program mixing technology is backward. No matter how big the mouth is, you can't talk nonsense." Add-on electric vehicle is a model with low threshold and out-of-date technology, which points out that the essence of add-on is "series plug-in hybrid".

Shen Hui, founder of Weima Automobile, also said earlier on this topic: "to rigidly judge whether a technical route lags behind or not, it is better to pay attention to what users really need." For users, what is easy to use is advanced, and 'easy to use' often means meeting the demand. From this point of view, technologies that pay too much attention to the advanced nature of technology while ignoring the actual needs of users have no prospects and have gone astray of 'engineer thinking'. "

It is understood that the added hybrid electric vehicle refers to the car that is driven by the motor and recharged by the engine. To put it simply, the car has both a motor and an engine, in which the motor is used to drive the wheels and provide power for the car. The engine does not participate in the drive, but consumes gasoline to generate electricity. The electricity generated by the engine is stored through the battery in the car and supplied to the motor while driving.

The good thing about the add-on power is its low cost, which requires neither complex gearboxes nor expensive batteries. For car companies, the cost is lower and easier to use, which is the biggest difference compared with pure electricity and PHEV. Technically, the added program structure is relatively simple and has a low threshold, which can shorten the R & D cycle and facilitate new brands of car companies to quickly push products and grab the market, while mixed R & D has a long cycle, a large investment, and requires years of technology accumulation. generally, it is also the choice of traditional car companies. Generally speaking, no matter added programs, pure electricity or PHEV, there is no absolute good or bad, but each chose a suitable way of playing for their own development.
