Plug and mix with gears, hurry back!
If you plan to buy a car, hesitate between range extender, single-speed hybrid and multi-gear DHT, I suggest you give up multi-gear DHT, this is my suggestion, of course, the money is your own, how you spend it is ultimately up to you, the decision is in your hands, let me talk about why it is recommended that you carefully choose multi-gear DHT plug-in hybrid models.
First of all, as Li Bin said, these are transitional technologies, there is no doubt that after the mass production of solid-state batteries, what plug-in hybrid range extension will become a thing of the past, even at the moment, if you rarely run long distances, it is urban commuting, I suggest you go directly to pure electricity, because after you buy a hybrid, you will find that you don't want to use oil at all, it is better to go to pure electricity.
Secondly, if you need to run long distances, find it inconvenient for pure electric models to travel long distances, have battery life anxiety, and are entangled between several hybrid models, I advise you to first exclude multi-gear DHT plug-in hybrids.
Multi-gear DHT is not an advantage of plug-in hybrid models, but a disadvantage! Be clear about that.
Multi-gear DHT models, by many bloggers, said by many bloggers, what engine can be more involved in driving, the engine can be directly driven at low speed, the role of the engine is more important, etc., but this is not an advantage. In the era of electric drive, allowing the engine to participate in the drive and play so many roles is against the trend and contrary to the development law of new energy vehicles.
Multi-gear DHT models, is to circumvent Toyota and BYD's patents, in addition, in order to give full play to the residual heat of the internal combustion engine, at the same time on the power battery price reduction, and the stability of the motor drive has no confidence, therefore, these traditional car companies have chosen the multi-gear plug-in hybrid route, at present, is a misguide.
I thought that it could reduce high-speed energy consumption, but because the engine participated in the drive, it could not achieve steady-state cruise, and it has been maintained in the high-efficiency range of work, but it increased energy consumption, resulting in the original advantage of high-speed energy consumption, and the range extender can not open the gap at all, and I thought that I could participate in the drive at low speed, which can increase the power performance of the vehicle, so I did a lot of work, the tuning of the internal combustion engine, the matching of the internal combustion engine and the gearbox, and the coordination of the internal combustion engine and the motor. As a result, the extended-range model simply uses a higher-power motor to easily achieve anti-killing. To summarize the multi-gear DHT plug-in mix, it is thankless, and the simple problem is complicated.
The original advantages of multi-grade DHT did not show the advantages of crushing, and the disadvantages of multi-grade DHT were very fatal.
The first is the increased cost and complex structure, which leads to the inability of multi-gear DHT models to put down a large battery and increase the cost, which is nothing to discuss, which is not only the cost of hardware, but also the cost of tuning and matching software. At present, the multi-gear DHT plug-in hybrid model with the highest pure electric battery life is Wei brand Mocha, with a pure electric range of 215 kilometers, and the range extender models with high pure electric battery life abound, with the continuous price reduction of power batteries, there will be more and more range extender models with large batteries, and at that time, the gap between the pure electric range of the two sides will be further widened.
Second, complex structure, more complex software matching and tuning logic, resulting in multi-gear DHT models to drive more like fuel vehicles, recently a car company also OTA upgrade a wave of firmware, the main thing is to solve the problem of shift frustration of DHT models, in the era of electric drive, but also to optimize the problem of shift frustration, a little funny, and the range extender is basically not the problem of shift frustration.
Third, multi-gear DHT has a higher risk of failure, for example, there is a greater risk of stall compared to the range extender, and there is a transmission failure problem, a certain brand, there has been a large area of gearbox quality problems, don't ask me which brand, you just need to search on the Internet to understand.
Multi-gear DHT models, in the final analysis, it is a fuel vehicle that can be driven by pure electric driving, it is still used to build fuel vehicles to build new energy vehicles, car companies feel that the cost of power batteries remains high, it is better to give more play to the residual heat of the internal combustion engine, but I did not expect that in the past year, the price of raw materials for power batteries has plummeted, and the cost of 100 degrees of power batteries has fallen to less than 50,000 yuan. The range extender is different, it has determined the direction of pure electric drive at the beginning, betting that the price of the power battery will be reduced, and now it is right.
Power battery price reduction, is undoubtedly good for the range extender, this year, we will see more pure electric range of two or three hundred kilometers of range extender models, large battery small range extension program, urban completely electricity, long-distance travel without range anxiety, is undoubtedly the best solution at present.
