At the SAIC Roewe E50 EV and Roewe 550 plug-in hybrid test drive meeting, a SAIC technician said: “The Shanghai users of the SAIC Roewe E50 new energy vehicle are mainly divided into two categories. One is because there is no license plate. I got a Shanghai license plate through the E50. Second, I really understand the new energy vehicle technology. I am a more loyal fan."

According to statistics, in Shanghai, the official guide price of the Roewe E50 is 234,900 yuan, a national subsidy of 33,250 yuan, a local subsidy of 40,000 yuan in Shanghai, a non-stop profit of SAIC Motor at 33,650 yuan, the actual selling price is only 128,000 yuan, and Shanghai New Energy can be obtained for free. Vehicle license. The official guide price for the Roewe 550 plug-in hybrid car is 248,800 yuan and 259,800 yuan. After enjoying the above subsidies, it will be 185,500 yuan and 196,500 yuan. It will also be able to obtain a Shanghai new energy vehicle license for free. This affordable nature naturally attracts many consumers.

However, because of the technology users who choose Roewe New Energy Vehicle, it is even more worthwhile for SAIC. This shows that SAIC's accumulated technology in the field of new energy has finally achieved great results. Zhu Jun, director of SAIC New Energy Technology Center, once said that the Roewe 550 plug-in hybrid car has mastered technologies that many multinational car companies do not have.

Because of repeated fire incidents, the safety of new energy vehicles is the subject of the public's greatest concern, and it is also one of the concerns about not buying new energy vehicles. According to SAIC technical personnel, Roewe's two new energy vehicles have made various technical enhancements in the security field. Take the Roewe E50 as an example, the battery compartment of the car is placed at the bottom of the car. Because SAIC conducted a real-vehicle test on the rugged road surface of the Roewe E50, according to the analysis of the final test results, it was found that the battery was the safest to install on the chassis. SAIC adopted special materials to protect the bottom of the Roewe E50 and to ensure its protection.

The most important thing to mention is the side column crash protection system. When an impact is encountered, the protection system can buffer and absorb the impact force and protect the battery to the maximum extent, thus ensuring the safety of the passengers in the vehicle. Through the collision energy management system, the front body structure can achieve stepwise energy absorption in frontal and 40-degree offset collisions, ensuring the safety of passengers in the vehicle.

Prior to this, after a certain foreign brand of electric vehicles crashed, no fire broke out on the scene. However, one month later, the battery was ignited by a chemical reaction due to extrusion. This shows that the battery is difficult to fire. To ensure battery safety, the Roewe E50 and Roewe 550 plug-in hybrids have passed stringent battery safety standards.

For example: The battery has reached the international advanced IP67 dustproof and waterproof protection level; the chassis battery compartment is equipped with a large number of anti-collision structure, which can guarantee the safety of the battery under the side collision and other extreme collisions; at the same time, it adopts a full range of high voltage/battery protection. The system includes high-voltage electric shock and leakage insulation protection, high-pressure system waterproof structure, and vehicle collision protection. He said, "With these technical guarantees, our E50 has survived a crash test and has not caught fire for more than a year."

The technician said: "The high-voltage power supply of the Roewe 550 plug-in hybrid car is designed according to the principle of multiple protection. From the parts, modules and systems to the vehicle, any level can automatically protect against external or own interference or In addition, technicians have designed an emergency switch in the battery pack so that once the vehicle is hit, the power supply is cut off from the middle, eliminating the danger of high voltage. The entire battery has a total of four protections to ensure safety."

He introduced that after delivery of the users, the two vehicles are also equipped with a remote real-time monitoring system. When the system is turned on, the background center monitors the technical status of the vehicle in real time. In the event of low battery power, abnormal vehicle data, and system alarms, etc., The back office staff will monitor the abnormality at the first time, and at the same time feedback to the vehicle intelligent information control system, light the warning light to alert the driver of the abnormality of the vehicle, and fundamentally protect the safety of the occupants.

In addition, in terms of motors, electronic controls, etc., the two new energy vehicles also reached a higher level of technology. In particular, the Roewe 550 plug-in hybrid car is equipped with the first domestic Green-motion high-performance triple-core hybrid engine group, including 1.5LVTI high-efficiency gasoline engine, Integrated StarterGenerator starter and Tractionmotor traction motor, which can automatically Switch the output of three power sources to achieve the balance of ultra-low fuel consumption and super power. Its fuel consumption per 100 kilometers is only 2.3 liters, while it can also output 160 kilowatts of peak power and peak torque of 587 Newton meters. EDU smart electric drive gearbox to replace the traditional mechanical gearbox is the highlight of the Roewe 550 plug-in hybrid car powertrain.

With the advancement of technology and the policy of promoting new energy vehicles, sales of SAIC new energy vehicles are increasing. According to data from the China Association of Automobile Manufacturers, in the first quarter of this year, sales of SAIC Roewe's new energy vehicles accounted for 12% of the total domestic sales of new energy vehicles. This year, the sales target of the Roewe 550 plug-in hybrid vehicle is 3,000. SAIC said that from the current sales situation, it is very easy to achieve this goal.
