As one of the most widely circulated slogans of BYD's plug-in and hybrid models, "fuel disruptor" is well known to many people and recognized by many people, and repeatedly reaching the top of the new energy vehicle sales list is proof of its strength.
However, people only know that the DM-i series model is very good, very sought-after, and there is a queue to pick up the car, and they don't know why it is good. And why is it sought-after? In other words, what exactly is it subverting?
Some time ago, I just had the opportunity to test drive the latest Song Pro DM-i 110km flagship Pro, and I felt a lot. So today, we will take this car as an example to analyze BYD's DM-i super hybrid system to see where it is powerful?
For hybrid technology, BYD has studied for nearly 20 years, and has now developed to the fourth generation of products, which was officially launched in 2020.
It is also from this generation of products that BYD has opened a dual-platform strategy, DM-p focuses on performance, and DM-i pursues energy saving. The slogan "Fuel Disruptor" was also widely spread with the popularity of dm-i series models.
This Song Pro DM-i, its power system is composed of a 1.5L engine and two high-efficiency motors, the combined power of up to 173kW. The structure belongs to P1 + P3, the generator is arranged in parallel at the engine output, the drive motor is placed behind the clutch, and the engine direct drive is also provided.
Coupled with BYD's self-developed electronic control system and blade battery, this car can achieve a variety of modes, pure electricity, series, parallel connection, kinetic energy recovery, engine direct drive. Whether it is urban or high-speed, all kinds of road conditions can be easily handled.
Based on the technical principle of more electricity consumption and less oil use, Song Pro DM-i has a very close experience to that of pure electric vehicles in most working conditions, with faster power response, better smoothness and better economy.
For example, in winter, most fuel vehicles will face cold start, idle speed, low-speed creeping and other situations, waste of time, not to mention, this is also the most fuel-consuming conditions of the engine.
Another example is urban travel, large traffic, many traffic lights, stop-and-go is not the best use scenario for fuel vehicles, fuel consumption is certain, and the discomfort caused by frequent gear changes and turbo lag is more annoying.
But song pro DM-i will not have such troubles at all. Driven by the motor at low and medium speeds, you can get on the bus and start without waiting. Various working conditions in the city are also more suitable for electric vehicles, whether it is experience or energy consumption, it is better than fuel vehicles.
Moreover, this top-equipped Song Pro DM-i is equipped with a lithium iron phosphate blade battery with a capacity of 18.3kWh, which can provide a pure electric mileage of 110km, which is enough for most people's urban commuting needs.
If you have a charging pile installed in your home, you can also use the trough hours to charge when you park at night. Taking the Shanghai area as an example, the electricity fee of Trough is 0.307 yuan / kWh, and the full charge of this car is less than 6 yuan, equivalent to less than 1 cent per kilometer.
If there is no charging condition, this Song Pro DM-i also provides a fast charging interface, which can charge from 30% to 80% in 30 minutes.
When the power is low or the speed is high, it is necessary to generate electricity or drive directly, this special Xiaoyun engine has been prepared under the system deployment.
It is also a very important part of the DM-i hybrid system. Based on highlights such as Atkinson's cycle and high compression ratio, the engine has a maximum thermal efficiency of 43.04%, whether it is power generation or drive.
Even in the feed state, the comprehensive fuel consumption of the Song Pro DM-i top model is only 4.5L/100km, and it only needs to be filled with 92# gasoline. Even if there is no charging condition, there is no problem in using it as a fuel vehicle, and its car maintenance cost is lower than that of the same level of fuel vehicle.
In summary, Song Pro DM-i is mainly driven by motor, supplemented by engine drive. Driving in pure electric or series hybrid at medium and low speeds and parallel hybrid at high speeds, taking into account both power and economy, while also having better driving texture and longer cruising range.
In the state of full oil and full power, the top-equipped Song Pro DM-i can provide a comprehensive cruising range of 1090km, which not only eliminates the mileage anxiety of pure electric vehicles, but also leads significantly compared with fuel vehicles.
If there is a need for long-distance travel or self-driving travel, then this Song Pro DM-i is more suitable. First of all, there is no mileage anxiety, you can go when you want to go; more importantly, the mobile power station function it has can give you a richer car usage scenario.
Based on this technology, Song Pro DM-i can incarnate a large "charging treasure" anytime and anywhere, and through the inverter, it can release 220V, 50Hz household AC, and the maximum discharge power is 3.3kW.
Whether it's a high-speed service area or a wilderness camp, cooking, k-singing, games, etc. are all within a question if you want. More importantly, through this function, Song Pro DM-i can also charge other pure electric vehicles, although the charging speed may not be so fast, but it is completely no problem in emergency.
So, as a "fuel disruptor", what exactly has the BYD DM-i series subverted?
Through the above analysis, we also have a clearer understanding, which subverts the power, energy consumption, driving texture, mileage, use scenarios and so on of the fuel vehicle. But more importantly, it upends the price of fuel vehicles.
In the price range of 138,800 yuan to 163,800 yuan, in BYD's product lineup, Song Pro DM-i is aimed at the most mainstream family consumers. This price range is also the most competitive market for self-owned brand SUVs, such as Haval H6, Changan CS75 PLUS, Andyo L, each of which has a high degree of heat.
What are their advantages? High configuration, large space, good design, excellent cost performance, which is the common advantage of most domestic cars. In these aspects, Song Pro DM-i is more than enough, and more importantly, BYD has achieved "the same price of oil and electricity".
In the past impression, the hybrid model due to the addition of motors, batteries, electronic control systems and other key components, the price is much more expensive than the same level of fuel vehicles, but also let many people have the idea of "plug-in hybrid models are not worth buying".
However, through more than ten years of technology accumulation, BYD has not only mastered the research and development of the core technology of the three-electricity system, but also has a strong production and supply system support, thus achieving the "same price of oil and electricity".
Consumers can buy plug-in hybrid models with a better experience and lower cost of use with the budget of purchasing fuel vehicles. The hot sales volume and the queue to pick up the car are the embodiment of its strength.
For the Song Pro DM-i car, there is no doubt about the product strength, and the question is never whether it is worth buying? How long do you have to wait to pick up the car?
In order to solve this problem, BYD has been trying its best to expand the factory and increase production capacity, and I believe that the problem of "long car pick-up cycle" will no longer be a problem.
