As the joint-venture brand plug-in hybrid vehicles enter the market one after another, the once-very-high-gloss independent plug-in hybrid vehicles gradually fade away, and the market share has been declining. However, with the development of some independent brands, more competitive plug-in technology has been introduced, which is expected to make a comeback of independent plug-in models.
Yesterday, SAIC passenger cars held an event in Shanghai about the third generation MG6? Analysis meeting of PHEV three-electricity technology. The feeling after listening is that compared with the old generation technology, the new generation of hybrid technology has made remarkable progress, not only with better performance, but also with lower cost, which is more conducive to market expansion.
so, what is the new generation of hybrid technology for SAIC passenger cars? With its blessing, what is its product strength and market prospect?
1. What is the technical strength?
first look at the third generation MG6? General arrangement of PHEV three-electricity system.
As can be seen from the figure, the third generation MG6? The core components of PHEV are: front drive, rear energy storage, and the middle is mainly connected components, such as oil circuit, circuit and exhaust device.
compared with other plug-in models, the third-generation MG6? The biggest difference in the layout of PHEV is the power battery, which is located under the trunk. Compared with the BYD system which is generally tiled under the chassis and the general system which is mainly located under the central armrest, the PHEV has the least influence on the lateral and vertical seating space. The low center of gravity is a good scheme for MG6, a sports car. Of course, it will sacrifice a little trunk space. However, if the rear seats are put down, the maximum space is still 124L L.
look at each component again.
this engine has the approximate parameters as shown above, and belongs to the "blue core" series of SAIC. We noticed that compared with the previous generation system, this generation system changed to a 4-cylinder machine. We don't know the reason behind this. Its efficiency is that although the cost will increase, NVH will be better in theory. In addition, for this engine, SAIC is the strongest in its class.
on the drive system, the new MG6? PHEV is upgraded to the second generation EDU, so-called EDU, that is, intelligent electric drive. The second generation EDU adopts a four-in-one architecture, which is highly integrated by high-power permanent magnet synchronous motor, 1-speed gearbox, motor controller and the second generation HCU intelligent hybrid control unit.
compared with the first generation, the most obvious change of the second generation EDU is that it changes from a double motor to a single motor, and with other matching components, it is said that it saves thousands of dollars. It is worth mentioning that this clutch is a dry clutch. According to the field engineer, the dry clutch can meet the requirements because the low-speed working condition is mainly driven by pure electricity and the engine rarely participates.
In addition, the gears of the second generation EDU have been upgraded from 2 to 1 (forward), including 6 on the engine side and 4 on the motor side. According to the engineer's electromotive force &; According to the reporter of Jingang New Energy, the gear ratio on the motor side is about 4-14.
as for the driving motor, we are all familiar with it. Hair-pin motor winding technology is adopted, which can effectively improve the motor power and operating efficiency, and is also beneficial to heat dissipation. SAIC emphasizes that it is the first independent brand to use Hair-pin motor winding technology.
as for the cooling mode of EDU system, the new MG6? PHEV adopts dynamic oil cooling technology for the first time, and according to SAIC, it is also the first vehicle in China to adopt this technology.
It is reported that after the application of dynamic oil cooling technology, it can cover a higher service temperature, reach racing level, and directly cool the heat source, which is more efficient and reliable. At the same time, due to the adoption of this technology, the continuous power and torque of the motor can also be improved by 1%.
we found that compared with the old model, the new MG6? PHEV adds about 2kWh battery, which makes the pure battery life reach 7 kilometers and the full charging time only takes 3.5 hours. It is worth mentioning that this battery pack is designed according to the most authoritative UL258 standard in the United States, which is considered to be the most stringent battery testing standard in the world.
although the third generation MG6? PHEV's three-electricity technology has been completely innovated, which is not only powerful in performance, but also very fuel-efficient and safe. But the core of this system is actually its IEM intelligent energy management system.
It is reported that the IEM intelligent energy management system can intelligently identify 11 major road conditions such as high speed, mountain road, congestion, speed limit and downhill, and intelligently select the power system mode according to the real-time road conditions, so as to realize the energy path planning and intelligent power management of big data navigation. By recommending the optimal energy consumption path, summarizing and displaying the trip benefits and other IEM explicit interactive modes, the use fun of IEM functions can be enhanced, the driving experience can be improved, and the efficiency of the whole trip system can be optimized to the maximum extent.
IEM intelligent energy management system is intelligent enough because it is combined with the second-generation HCU intelligent hybrid central controller to form the "super brain", which can dynamically collect information such as road information, radar information, navigation information, personal driving style, vehicle energy state, etc., and realize intelligent switching of various hybrid modes and optimization of electricity and oil consumption.
2. What is the product competitiveness and market significance?
on September 12th, the third generation MG6? PHEV is officially listed, and the price of new car is 1398-166,8 yuan. Yes, SAIC has lowered the price range of A-class plug-in hybrid vehicles to 13, yuan, which is further reduced compared with the same-class automatic oil-blocking vehicles. For the third-generation MG6 alone, its low allocation has been fully connected with the automatic oil-blocking vehicles.
when the electromotive force &; According to Jingang New Energy, the problem of high cost and high selling price of plug-in hybrid models, which was widely criticized before, is being solved by SAIC. The drop in the price means that the market is stronger, and SAIC is worth looking forward to. It is also worth noting that the third generation MG6? The performance of PHEV has not decreased, but has been strengthened.
first of all, the power, the third generation MG6? The maximum horsepower of PHEV is 35PS, the maximum torque is 48N·m, and it breaks 1 in 6 seconds, which is basically comparable to the power output of mainstream 3.T models. In the transmission part, due to the adoption of the world's only second-generation 1-speed EDU intelligent electric drive gearbox, the .2-second sports car-class dynamic response is realized.
secondly, fuel consumption, the third generation MG6? The comprehensive fuel consumption of PHEV has dropped from 1.5 to 1.1L per 1 kilometers, which is very impressive. This figure is the lowest among all hybrid models equipped with turbine engines, including independent brands and joint venture brands.
in addition, the third generation MG6? The fuel consumption of PHEV in state B is only 3.9L/ 1 km, that is, the actual fuel consumption under feed, which is close to or even better than the fuel consumption of Toyota Corolla/Ralink twin-engine which is famous for its ultra-low fuel consumption.
the acceleration performance is super strong, and it is also very fuel-efficient. It has passed the third generation MG6? With PHEV's hybrid technology, SAIC has overcome the dilemma of performance and fuel economy. This is of great significance not only to the marketing of plug-in hybrid vehicles, but also to the breakthrough of independent brands in plug-in hybrid technology.
in fact, according to SAIC, the third generation MG6? PHEV's new energy and three-electricity technology not only won the National Science and Technology Progress Award, but also has four international patents, which laid a solid foundation for China plug-in hybrid vehicles to enter the international market.
