The new third-generation Roewe super-hybrid eRX5 reshapes the new hybrid pattern of its own brand

In today's hybrid vehicle market, there are roughly two types of series-parallel super hybrid models. One is a dual-motor version. The first to promote dual-motor is Honda's iMMD hybrid system; the other is a single-motor version. More representative is Toyota's THS hybrid system.At present, most of the super hybrid systems used by domestic manufacturers are dual-motor versions, while the super electric drive EDU G2 Plus launched by Roewe and mounted on the new third-generation Roewe super-hybrid eRX5 is a single-motor hybrid system.

What is the super electric drive EDU G2 Plus?

Before introducing the Roewe system, let me explain the difference between the dual-motor hybrid system and the single-motor hybrid system on the new third-generation Roewe super-hybrid eRX5?Dual-motor hybrid and single-motor hybrid are completely different in terms of technical ideas. It can be described in a better-understood way: dual-motor hybrid is an addition based on pure electric vehicles, while Roewe super electric drive EDU G2 Plus is It is based on the addition of fuel vehicles.There is no difference between these two ideas, but they have their own characteristics in the way of implementation, giving consumers different choices of ideas.

The basic logic of the dual-motor hybrid is a pure electric vehicle. In order to solve the mileage anxiety, a hybrid system is added. This system is simply composed of an engine and an attached GM small motor.Therefore, it will be more like an electric vehicle during use, and it is directly driven by the motor in most working conditions.Since there is no conventional gearbox, a minimum speed threshold is required if the engine is to be driven directly.

Roewe Super Electric Drive EDU G2 Plus is a single-motor, multi-speed plug-in hybrid configuration. The basic logic is to make the engine and motor work in their best working conditions, and decouple the engine and the motor through the gearbox. , make different power allocation, make the vehicle achieve better economy.

The Roewe super electric drive EDU G2 Plus uses a set of 2*5 intelligent gearbox. It can be seen from the structure diagram that the motor and gearbox are highly integrated. Through a gearbox, the power of the motor and the engine is integrated and output. onto the drive shaft.The transmission can freely adjust the power output of the engine and electric motor through 10 gears.

Compared with the dual-motor hybrid system, the single-motor is more complicated.Because the transmission system of the EDU G2 Plus needs to be coupled and integrated with the motor, clutch, and gear shift, and requires greater shift smoothness.And not all OEMs can do a single-motor hybrid, because the single-motor hybrid system requires a lot of technical accumulation in gear matching and power connection adjustment, which is a necessary condition for the maturity of the single-motor hybrid system.As the first domestic car company to make a dual-motor hybrid system, why did SAIC choose a relatively more difficult path?In a live class, the engineer gave the answer: "After you have dual motors and then decide to make a single motor, you will not blindly pursue high parameters. Only by developing a better single motor model can you surpass yourself."

What are the advantages of the super electric drive EDU G2 Plus?

The biggest advantage of the super electric drive EDU G2 Plus is in the power. If you can sum it up in one word, it is "fast!" It has an absolute advantage in terms of parameters. The new third-generation Roewe super-hybrid eRX5 has a 180kw super-large motor. The motor can output 270N.m, has 10 gears, and supports full power shifting. The acceleration from 100 kilometers can reach 6.9s, and even the single-person test can reach 5.9s!The super electric drive EDU G2 Plus is combined with a 1.5T engine, which can burst out 570Nm of torque and 432 horsepower.So why does Roewe's hybrid system have such a strong power?Let's analyze it technically.

Compared with Toyota THS, which also uses single-motor hybrid technology, the biggest difference lies in the gearbox. Roewe adopts a self-developed intelligent gearbox, and the new third-generation Roewe super hybrid eRX5 EDU G2 Plus super electric drive 2 × 5 Intelligent gearbox, original adaptive shifting, mechanical decoupling of motor 2-speed shifting and engine 5-speed shifting to achieve 2×5 10-speed shifting, which can easily complete seamless shifting. It is the best in terms of transmission efficiency and power response. Better than the eCVT used by Toyota. Assuming that both Toyota and Roewe are in a feeding state at the same time, from the perspective of the gearbox alone, the dynamic response and driving experience of the Roewe model will most likely be better than that of Toyota.If you have driven a Toyota THS that feeds power, you probably understand what "feeding a bug" is.

In terms of matching motors, the new third-generation Roewe super-hybrid eRX5 is equipped with a 180kw I-pin flat wire winding motor, which is at the forefront of the current hybrid models in terms of single motor power!Toyota, which also uses a single motor, has only 88kw dual-engine Camry.With the support of a better gearbox and a larger motor, the new third-generation Roewe super-hybrid eRX5 achieved a good performance of 6.9s per 100km/h and 5.9s in a single person measurement, which has an advantage over competing Roewe products of the same level. .

At the same time, thanks to the I-pin flat wire winding structure, more coils can be accommodated under the condition that the size of the rotor remains unchanged, so that the working efficiency of the motor will be higher, and the power will be saved at the same speed. will be higher.Therefore, the new third-generation Roewe super-hybrid eRX5 theoretically achieves fast and power saving.

In addition to "fast", another major advantage that has to be mentioned is "safety". The Roewe hybrid system uses lithium iron phosphate battery packs. The new third-generation Roewe super hybrid eRX5 is equipped with a set of 12.3 kWh batteries. battery pack.First of all, the capacity of the battery pack is not small, 12.3 kWh can achieve 61 kilometers of pure electric battery life under NEDC conditions.According to the WLTC working conditions under the latest China 6 regulations, it can achieve a pure electric range of 50 kilometers.In terms of pure electric battery life, it is completely sufficient to meet the use in urban areas.Secondly, based on the characteristics of lithium iron phosphate batteries and Roewe's excellent battery thermal management technology, Roewe proposed "battery 0-burning technology", which has come up with its own excellent solution to the current intensifying battery safety problems.

Finally, the "economical" Roewe has launched the IEM intelligent energy management system. This system can adjust the source of power according to different road conditions, such as using the engine at high speed, using the electric motor when stuck in traffic, and through various modes such as driving mode and power recovery. , it can optimize the fuel consumption of 0.5-1L per 100 kilometers, and can make the NEDC comprehensive battery life of the new third-generation Roewe super-hybrid eRX5 reach more than 1050 kilometers.

How different is the appearance of the new third-generation Roewe super-hybrid eRX5?

I have also mentioned the current hybrid technology of domestic manufacturers, and all of them have chosen dual-motor technology. Whether it is adding a few DHTs, whether it is Raytheon Power or DM-i, it is essentially the same.The advantage is the same driving texture as an electric car, but the problems of the dual-motor version are gradually exposed in the test of the market.For example, in a certain company's "EV limited" incident, although the problem was basically solved through OTA upgrade, the high-speed fuel consumption also increased from 4 liters per 100 kilometers to 7 liters per 100 kilometers.

And the super electric drive EDU G2 Plus hybrid technology on the new third-generation Roewe super hybrid eRX5, thanks to the structural difference of the single-motor hybrid system, there will never be an "EV limited" situation.And under high-speed conditions, the engine and gearbox can make different output combinations, and high-speed driving will be more fuel-efficient.

In general, the emergence of the new third-generation Roewe super hybrid eRX5 and the emergence of super electric drive EDU G2 Plus hybrid technology are beneficial to the domestic hybrid vehicle market.

First, it gives consumers more choices. Hybrid models with more economical car costs have long been the first choice for consumers to buy a car. However, before the dual-motor hybrid models on the market focused on high-speed vehicles for some car use scenarios. Consumers on the Internet are not friendly. The emergence of the new third-generation Roewe super-hybrid eRX5 solves the vacancy in this market. For consumers who have high-speed needs, the super electric drive EDU G2 Plus hybrid system is better than other brands of hybrid systems. system is more appropriate.

Second, it stimulates the current domestic hybrid market. At the time when the hybrid vehicle category is rapidly breaking out, Roewe launched its own third-generation super-hybrid eRX5, but the EDU G2 Plus technology is not a product that is temporarily launched in the market, but It is the result of continuous technological iterative development to the third generation.SAIC's own brand plug-in hybrid is one of the earliest domestic plug-in hybrid models exported overseas, with the largest export sales, and global sales have maintained rapid growth.Sandian system has also passed strict global standard testing and certification, and the quality is guaranteed.
