Have you noticed that the word-of-mouth of the range extender is reversing.
Three years ago, public opinion in the automobile circle was almost one-sided, what was the range extender? With multi-grade DHT plug-in mixing ratio? The range extender can be done, the multi-gear DHT engine can be driven at a speed of 60 per hour, the multi-gear DHT has several gears, the multi-gear DHT engine can be directly driven, can the range extender be?
But the sales soon slapped the face, the data shows that the best multi-gear DHT model currently sold is the Galaxy L6, with sales of more than 6,000 years, this sales volume is far worse than the range extender model, and the sales of the range extender model show a trend of multi-point flowering, and the sales of multi-gear DHT hybrid models are relatively sluggish as a whole.
Many people are praising multi-gear plug-in hybrid models, very hard, insisting that multi-gear DHT models are better than range extenders, but when it comes to sales, there is no confidence, and even very double standards, saying that the good sales of range extender models are not outstanding technology, but the new forces that make range extender models, the main focus is intelligent driving and color TV refrigerator sofas, which will be marketed than traditional car companies, but they can't explain why Chery's range extender models sell better than their own multi-gear DHT models.
After reading a few so-called car critics, they turned the range extender into garbage and regarded the multi-gear DHT as an advanced technology, but in addition to the fuel consumption of the multi-gear DHT high-speed direct drive is lower than that of the range extender, and the engine can participate in the drive, I can't tell what advantages the range extender has.
In fact, multi-gear DHT in the era of electric drive, is really taking off pants and farting, is against the trend, I hope many people can objectively look at the advantages and disadvantages of range extender and multi-gear DHT.
First of all, the disadvantage of the range extender is undoubted, that is, the high-speed energy consumption, which is about 3-6% higher than the multi-gear DHT model. Urban fuel consumption, range extender and multi-gear DHT models, can not open the gap at all, note, this is in the case of the efficiency of the range extender is about the same, you hold the ideal ONE holding the garbage range extender, and the comparison with the multi-gear DHT model with high thermal efficiency, it is meaningless. In fact, many extended-range models are considered by many people to have high fuel consumption, mainly because new car-making forces often can't get a good range extender.
There are many people who imagine that the power performance of the extended range is not as good as that of the multi-gear plug-in hybrid, in fact, it does not exist, you can observe that the motor power of the extended range model is often greater, which can make up for the power advantage that the engine can not participate in the drive.
And for this 3-6% high-speed energy consumption, what do multi-gear plug-in hybrid models need to pay?
1. The structure is more complex, the production cost is higher, and the cost of software tuning is also higher, resulting in the price of multi-gear DHT models is often higher than that of extended-range models, either sacrificing configuration or increasing the price, and there is no other way, which is also the direct reason why extended-range models sell better.
2. It cannot be co-developed with pure electric models, and co-linear production increases the cost of R&D and sacrifices the flexibility of product layout.
3. The extended-range structure sacrifices the flexibility of the layout of the chassis, resulting in the inability to realize four-wheel independent drive, and the inability to put down a larger power battery, the current multi-gear DHT model with the highest pure electric battery life is the Wei brand Mocha, with a pure electric range of only 215 kilometers.
4. Multi-gear DHT models, it is necessary to let the internal combustion engine participate more in the drive, which increases the problem of frustration, many people say that my range extender car does not have a frustration, that is not compared with the motor driven model. In addition, at present, there are brands of multi-gear DHT models on the market, and the failure rate is relatively high, including transmission failure and stalling.
5. On multi-gear DHT models, it is difficult to achieve a high level of high-end intelligent driving, why Huawei chooses the range extender solution, there are also reasons, the range extender is fully motor driven, and the intelligent driving scheme of electric vehicles can be calibrated together, and multi-gear DHT, involving gear shifting, involving the coupling of engine power and motor power, therefore, it is very difficult to achieve millisecond response without frustration and fuel saving.
It is precisely because of the above reasons that Huawei, Ideal, Nezha, and Leap have all chosen the route of range extender, many people say that this is because they can't build internal combustion engines and gearboxes, so why did Chery, Changan, GAC, BAIC, AND Dongfeng also join the ranks of range extenders? Is it because they can't build engines and gearboxes?
The advantages of multi-grade DHT, the advantages of high speed and low energy consumption, can be perceived by many consumers? How many high-speed does a normal consumer run in a year? What's more, the range extender often has a longer pure electric range, admit it, even if the multi-gear DHT is used as a transitional scheme, it is not the opponent of the same transitional scheme range extender, and the next three years will be clear.
