Powerful and fuel-efficient, what are the advantages of the second-generation EDU electric drive system technology?

We can find that electric vehicles have developed rapidly in the past two years, and charging facilities have also been popularized quickly. However, the anxiety of long-distance driving, low-temperature endurance, and long charging waiting time are all small bugs that are difficult to solve. So from the market situation last year, we found that plug-in hybrid vehicles are becoming more and more popular. And when choosing a car, users actually care more about the plug-in hybrid technology. So, today we will take a look at the current popular Roewe RX5 ePlus, which is equipped with SAIC's second-generation EDU electric drive system, and what are the advantages.

The Roewe RX5 ePlus is equipped with a plug-in hybrid system consisting of a 1.5T engine with a maximum power of 169 horsepower, a pure electric range of 52km, and an official minimum comprehensive fuel consumption of 1.6L per 100 kilometers. Its biggest highlight is the second-generation EDU electric drive system, which consists of a 6-speed transmission on the engine end and a 4-speed transmission on the motor end. It can be composed of up to 24 gears, which can cover more driving conditions and better balance energy saving and performance. For example, there are corresponding gears when energy saving is needed, and there are corresponding gears to cope with strong power when strong power is needed. This is the power of the second-generation EUD system. Of course, it is precisely because of this that the second-generation EDU electric drive system has a transmission efficiency of more than 94%, and a power response speed of less than 0.2 seconds, which also makes the Roewe RX5 ePlus look very smooth.

In addition, the Roewe RX5 ePlus not only uses the second-generation EDU electric drive system, but also adds an IEM intelligent energy management system. This system can intelligently adjust the vehicle's kinetic energy recovery intensity and power output according to different road conditions, making the fuel-saving performance even better than the Corolla PHEV.

Simply put, the IEM intelligent management system can realize intelligent power system regulation and intelligent power regulation. After turning on this function, the map navigation information and environmental information can be used to intelligently identify and judge 9 major road conditions such as entering a roundabout, speed limit camera, downhill, etc., and autonomously control the vehicle status such as energy recovery intensity and power system operation mode, so as to select the most suitable power system operation mode for the user and release the ultimate efficiency of the "green core". For example, when the user encounters a red light and has a strong need to decelerate, the iEM intelligent energy management system will actively increase the energy recovery intensity, let the car decelerate quickly as expected by the driver after releasing the accelerator, and store the energy in the battery pack, so that it will not waste fuel due to braking, nor will it be squeezed by the car behind due to slow deceleration.
