Looking back at the independent brand camp, under the guidance of policies, the trend of independent brands developing new energy sources in recent years is obvious. Today, it's hard to say whether new energy can help them achieve overtaking in corners, but for those powerful independent brands, they have really conquered the position of PHEV technology.
Representative model: 20 19 MG 6 new energy 50T trophy 5 2nd edition.
On April 27th, SAIC launched a modified model of MG 6. Although it is an "annual" model, the upgrade range is quite large, especially for new energy vehicles. With the introduction of "50T" powertrain, the car has become "Shuang Sheng" in terms of performance and technology.
20 19 MG 6 and new energy vehicles are not much different from the old models in appearance, while the "5-second version" blackens some decorative strips on the basis of conventional models to strengthen its own sports tonality.
As the focus of this change, the "New Energy" model is equipped with an inline four-cylinder 1.5T engine, which is matched with the 10-speed EDU gearbox. The latter adopts the design of 6-speed engine end +4-speed motor end, and realizes the speed change effect through the cooperation of electronic control clutch and gear set.
At the same time, the front axle drive motor of the new car adopts hairpin winding structure, which cancels the previous ISG motor. According to the published data, 1.5T engine can generate the maximum power of 124kW, and the comprehensive output power and torque of the whole PHEV system are 224kW and 480N respectively. m .
In addition, the car is equipped with a ternary lithium battery pack with a capacity of 9. 1kWh, which can realize pure electric battery life of 5 1km under NEDC working conditions. When using slow charging equipment, it takes 3.5 hours for the battery to be fully charged.
The new power system not only makes this product have stronger and more consistent output performance, but also adds a mandatory EV mode to the new car. Through the original intelligent charging, charge maintenance and forced charging, the car can provide four power transmission modes and three driving modes: ECO, NORMAL and SPORT.
In addition, the redesigned MG 6 new energy vehicle also has the function of energy recovery gear memory. When starting the vehicle again after the flameout, there is no need to set relevant functions repeatedly, and the humanized function is improved.
At present, the Roewe and MG brands under SAIC have a variety of PHEV and pure electric vehicles, and the launch of 20 19 MG 6 new energy means that SAIC's harvest in this technical field has begun.
Representative model: Tang DM
BYD, as one of the earliest car companies in its own brand to deploy new energy products, has provided gasoline, plug-in hybrid (DM) and pure electric versions for its models so far, which has blossomed in three major areas and market segments of cars, SUVs and MPVs, and even some models have 5-seat, 6-seat and 7-seat versions, with a huge lineup.
"Tang" is a medium-sized SUV model of this brand. According to the cruising range of pure electric vehicle, the vehicle is divided into two versions: "DM80" and "DM 100", with carrying capacity of 19.96kWh and 23.97kWh respectively, and the comprehensive cruising range of pure electric vehicle is 8 1km and 100km respectively.
In terms of power, BYD Tang DM's PHEV system consists of a 2.0T engine and a "three motors", including a 48V BSG starter motor (not involved in driving) with an output of 1 10kW power /250N? M torque front axle motor, output 180kW power /380N? M torque rear axle motor, the comprehensive power of the system is 44 1kW, and the torque reaches 950N? M. It can realize electronic four-wheel drive, and there is no longitudinal transmission shaft between the front and rear axles, and it is a 6-speed dual-clutch gearbox matched with the engine.
In addition to eye-catching dynamic parameters, the car also provides two driving modes, HEV and EV, as well as ATS terrain feedback system. EV mode is pure electric four-wheel drive. The key point is that when the battery charge is lower than 15%, the car can automatically switch to HEV mode, charge the battery pack with the help of the engine and braking energy recovery device, and ensure the battery charge is between 15%-25%, that is to say, even if the charging pile cannot be found, the car can be driven by hybrid power.
Today, BYD's DM and E platforms have developed to the third generation. Through the continuous optimization of transmission logic and efficiency, the fuel economy of PHEV models has been improved, and the "dependence" on charging piles has also been reduced, further catering to consumers' actual car habits.
Representative model: 20 18 Changan CS75PHEV
CS75 can be described as the sales responsibility of Changan Automobile in the SUV field, and the PHEV version of this car provides consumers with new choices, and from a technical point of view, the technology content of this car is not weak.
The power system of CS75PHEV consists of 1.5T engine and front and rear dual-drive motors. The comprehensive output power of the system reaches 255kW, with 605N? M torque, which can realize electronically controlled four-wheel drive and provide road modes including snow, sediment and mountains, while the single-stage reducer and the rear-axle two-stage reducer are provided by GKN and Schaeffler respectively.
With the help of the battery pack with the capacity of 12.96kWh located in the middle of the front and rear, the pure electric cruising range of the car can reach 60km, and it takes 4 hours to fully charge the battery when using the slow charging device. It is worth mentioning that the car can use the P 1 generator located between the engine and the gearbox to charge the battery pack, and at the same time, it can make an appointment to charge in the on-board system and set the charging speed, which is convenient for the owner to avoid the electricity price peak.
In addition, the car offers four driving modes: EV, AUTO, CHARGE and SAVE***. In EV mode, the top speed of the car can reach 130km/h, and the engine will not intervene until the battery is exhausted. The intervention timing of automatic mode engine depends on the throttle depth. The key point is that the energy recovery intensity of the automobile can be adjusted in six gears by shifting paddles.
At present, Yidong, CS 15 and other models under Changan Automobile have launched pure electric versions. Although CS75 PHEV makes up for the brand's shortcomings in the field of "hybrid", compared with its huge product lineup, the proportion of new energy vehicles still has room for improvement.
Representative model: 20 19 Jiaji New Energy
Cargill is not only the first MPV model under Geely brand, but also the first MPV model equipped with PHEV system in its own brand. Pure fuel, MHEV, PHEV versions * * * and 1 1 models are listed simultaneously to meet the car purchase needs of different consumers to the greatest extent.
Structurally, the PHEV system adopted by Cargill New Energy is basically the same as the Borui GE PHEV model, but the output power is slightly different. Among them, the inline 3-cylinder 1.5TD engine is made by Geely and Volvo, and its maximum power and torque are 130kW and 255N respectively. M, the motor is connected in parallel on the even shaft of the 7-speed dual-clutch gearbox to realize hybrid power output. The comprehensive power and torque of the system are 190kW and 385N respectively. m .
The ternary lithium battery pack with the capacity of 1 1.3kWh is located under the second row of seats. Geely official said that charging the battery pack from 0 to 100% does not exceed 1.5h, which can provide the car with 56kW pure electric mileage.
Like most PHEV models of its own brand, Cargill New Energy also supports EV and HEV, and the throttle response of HEV mode can be adjusted according to sports, comfort and ECO mode. It should be noted that the car can switch to HEV mode by stepping on the accelerator deeply in EV mode to ensure the maximum power output in overtaking, merging and other scenes.
In the face of the overall transformation of the automobile market to new energy sources, and the opening of the second child policy in China for many years, the scene of "one car for one family, one car for many people" will increase day by day. In Che Yun's view, this is why Geely set foot in MPV market and offered three power options. It is undoubtedly a long-term solution to lay out products before consumer demand.
Representative model: 20 18 WEY P8
P8 is the only new energy vehicle of Haval and WEY brands at present, but its technical content is by no means superficial. The car is built on an independent Pi4 platform, and its plug-in hybrid system includes a 2.0T engine, which can output 15kW/50N respectively. M consists of 85kW/195n m front axle BSG motor and rear axle motor, equipped with a two-speed reducer, and the transmission system is served by a six-speed dual-clutch gearbox.
The comprehensive output power of the system is 250kW, and the comprehensive torque reaches 524N? M, with the help of the battery pack with the capacity of 12.96kWh, the pure electric mileage of this car is 50km.
WEY P8 provides five driving modes: automatic, sport, electric, energy saving and AWD * * *. In EV mode, when the battery power is less than 24%, the frequency of engine intervention will increase significantly, and when the remaining power is less than 16%, the car cannot enter the pure electric mode. SAVE mode engine can charge the battery pack, which relieves the vehicle's high dependence on charging piles to some extent.
In Che Yun's view, the highlights of P8 technology listed on 20 18 are still eye-catching. On the other hand, its sales volume (2010 vehicles sold in March/910) is also a good achievement for Great Wall.
Representative model: 20 19 Chuanqi GS4 New Energy
As a PHEV version of Chuanqi GS4, the appearance of the car has not been whitewashed too much. The powertrain is a combination of 1.5L naturally aspirated engine and front axle motor. The former adopts Atkinson cycle with better fuel economy, and their maximum power is 7 1kW and 130kW respectively, and the torque reaches 120N? M and 300N? M, the transmission system is a single-speed gearbox for electric vehicles.
The 12kWh battery pack of this car is provided by Wanxiang and is designed with liquid cooling device. It takes 3 hours for the battery to be fully charged, and the mileage of the Ministry of Industry and Information Technology is 58km. From the driving mode, its PHEV system is closer to the extended-range hybrid. In the case of sufficient power, the power output mainly depends on the motor, but when accelerating or overtaking, the engine will also intervene to charge the battery.
It should be noted that, depending on the vehicle speed, the probability that the engine is used for "power generation" is greater than that for "transmission", that is, it can be divided into two working modes: high-speed and low-speed range extension.
At this stage, GAC New Energy has only two plug-in hybrid models, Chuanqi GA3PHEV and Chuanqi GS4 PHEV. In contrast, with the growth of Aion family, the strength of its pure electric lineup will be more impressive, and the "transition" attribute of PHEV models will become more and more obvious.
Representative model: 20 17 zino 60H
Zino, which belongs to BMW Brilliance, is the representative of the "joint venture and independent" brand. Considering the inextricably linked with BMW, the technology of its models can be easily traced back to the source.
Zino 60H has a high similarity with BMW Brilliance X1"25LE" in both design and power structure, such as 1.5T three-cylinder engine, 10.7kWh lithium battery pack, 70kW rear axle motor and 6-speed automatic manual transmission. The comprehensive output power and torque of the system are 170kW and 385N, respectively. M, and can realize timely four-wheel drive, pure electric mileage of 60km.
There are three driving modes: AUTO EV, MAX EV and SAVE. In AUTO EV mode, the computer will choose pure electric or hybrid driving according to the data such as throttle depth, while in MAX EV mode, the engine will not participate in the work, while in SAVE mode, the engine is responsible for driving and charging at the same time, but the battery cannot be fully charged.
In Che Yun's view, Zhi Nuo 60H can be regarded as the product of "takenism". Its hardware is the same as "BMW", but it is under another brand.
China's new energy policy orientation has promoted the research and development of major car companies and related technologies to a certain extent. However, if we carefully observe the product layout and development of independent brands in recent years, we can easily find that some products born under powerful independent brands are gradually changing from "fitting policy" to "catering to the market".
For example, BYD, in addition to implementing a multi-power combination coexistence scheme for a car, the model represented by "Tang" in this paper is no longer based on the "national standard" with a pure battery life of not less than 50km, and the third-generation DM and E platforms are put on the market, which has made great progress in optimizing energy output logic, reducing fuel consumption in power failure and reducing dependence on charging piles.
Moreover, at present, technologies such as 10 speed EDU, rear axle drive axle, "hybrid four-wheel drive" and Atkinson cycle engine can be seen in new energy products of independent brands. Perhaps there is still a gap between independent brands and overseas brands in terms of power performance and comprehensive efficiency. From the perspective of "daring to act" and accelerating landing, the catch-up of local brands is gradually narrowing the gap between brand attributes and technical reserves.
The key point is that "hybrid" is only a transitional stage on the road of electrification, but it is very important for paving the way for pure electric products. For this reason, SAIC Roewe MARVEL X, GAC New Energy Aion S and Geely Geometry A appeared, which showed us its dedicated pure electric platform.
It can be seen that on the road of "getting an electric shock" step by step, the strategy of independent brands is changing from passive to active, and the understanding of technology is more profound.
