Before explaining the technology of EQC in detail, let's go over the parameters first: EQC is made in China by Beijing Benz, and the manufacturer's guide price is 49.98-62.28 million yuan. It is positioned as a medium-sized pure electric SUV with a body length, width and height of 47741* 890 *1622 mm.
Chassis and circuit architecture
85% of the chassis of EQC is newly developed, 65,438+05% is designed and parts for GLC fuel vehicles, and the body-in-white is designed for GLC***. Judging from the photos, the layout structure of the SUV chassis is not particularly problematic. The front of the car has a cage structure, which "frames" the front motor and some large electrical equipment.
Some people think that the white body of GLC limits EQC's imagination, and the front motor set framed by iron cage is very similar to the layout of fuel vehicles.
This may make innovators feel that there is no bright spot and it is too traditional. But the author believes that Mercedes-Benz's big data on traditional recipes is extremely rich and reliable. Perhaps EQC has no obvious advantages in production and weight control. However, EQC has enough experience in safety data and reliability to support it, which is the biggest difference between traditional manufacturers and new manufacturers.
In the picture, the battery pack is completely protected by the frame.
In addition, according to the trademark information submitted by Mercedes-Benz in the Trademark Office of the State Administration for Industry and Commerce, Mercedes-Benz EQ brands are expected to be divided into seven categories, and even integrated into the debugging of AMG to launch AMG EQ models. In 2022, Mercedes-Benz will build 10 electric vehicles.
Next year, EQA, EQB and other models will come out one after another, and they will come from Mercedes-Benz's EVA pure electric platform. Wait for the EVA platform model to go on the market, and then judge the chassis layout of EQC. Recently, we also realized that besides the three electrical systems, the electrical architecture and optimized circuit system are the foundation of a smart car.
Battery and cruising range
The battery used in domestic EQC is selected from Contemporary Ampere Technology Co., Ltd., with a total battery capacity of 79.2KWh and an official cruising range of 4 15km. Compared with the new forces with cruising range of 500, 600 or even 700, 465 and 438+05 kilometers are really not outstanding, but if you commute in a city like Beishangguang or cross an intercity like Beijing and Tianjin for about 200 kilometers, the cruising range of about 400 kilometers can meet the usage scenarios.
What makes Mercedes-Benz officials more confident is that the calculation of EQC cruising range takes into account comprehensive factors: speed, temperature, driving habits, road conditions, load and so on. In our actual test drive, the performance cruising range is basically the same as the actual cruising range, with only a small initial entry, which can really bring great security to users.
According to our actual test, the road conditions and expressways in Tianjin actually travel 43km, and the cruising range is reduced from 106km to 67km, with a loss of 39km, which is unexpected. After all, other people's homes have "fallen much" and they have seen "falling less" for the first time. But there is also the driver's factor, because after the cruising range is lower than 100km/h, the driver will pay more attention to controlling the speed.
The actual power consumption rate is 23.7kWh/ 100km, which can achieve our goal of saving energy when we enter ACC adaptive cruise state on the actual urban expressway, with a minimum of 20kWh/ 100km.
At the same time, we also measured the charging of EQC. According to official data, the battery charge of EQC in fast charging mode will not exceed 45 minutes from 10%-80%, but the charging power needs to reach 74kW or more.
However, in practical use, pure trams are highly dependent on the perfection of charging facilities and the working conditions of charging equipment, especially under long-distance driving conditions. Moreover, our trip to Tianjin mainly promotes hybrid vehicles, especially around the city, and the charging facilities are not satisfactory in terms of density and maintenance.
We went to make the first call and were told that the equipment had been out of service for "several years". The second company found a fast charging device, and the actual charging power is only 10.42kW, which is a common situation for pure electric car owners in second-and third-tier cities. I can only hope that the new energy supply facilities in China will be improved in the future.
Therefore, although I personally suggest buying pure trams and actually using new energy vehicles, I suggest that friends who buy new energy vehicles must first ensure that they have household charging piles and are stable enough.
Driving experience
EQC offers two power versions, both of which are dual-motor versions. Shall we drive to EQC? 400? 4MATIC version, the maximum power of dual-motor combination is 300kW, EQC350? The maximum power of 4MATIC is 2 10kW.
As the EQC vehicle weighs nearly 2.5 tons, it can be seen from the chassis structure displayed that the suspension part has been strengthened.
In actual driving, pure electric vehicles have inherent advantages in NVH field. EQC has a quieter driving experience and less feedback. It can be felt that engineers are trying to adjust EQC to the shadow of Mercedes-Benz in different driving modes, but after all, pure trams have their own characteristics, and the front section is more sensitive than fuel vehicles.
Generally speaking, the driving experience is excellent, and many friends say that he can compete with S-class. Personally, I think it should be from the aspects of mute and power output ability.
I am deeply touched. I used to drive a fuel car. I don't need to look at the dashboard. I can roughly judge the speed by the feedback of tire steering and noise. Driving EQC at high speed will unconsciously overspeed.
MBUX and Real Scene 2 Navigation
Judging from the big data given by Baidu, the current users' dependence on car machines mainly focuses on navigation, vehicle function setting, music search and practical services (ordering and booking tickets).
In order to alleviate and solve the mileage problem, EQC navigation has the function of route optimization for electric vehicles. As long as the destination information is input, the vehicle can intelligently give the driving route and mark the charging pile information on the road. The owner can set the remaining cruising range after arriving at the destination, so that EQC can calculate the most convenient and efficient distance for charging along the way.
In addition, EQC also has AR real-life navigation function. At the fork in the road, the car can display the real scene shot by the front camera and mark the walking route in the real scene.
Driving assistance function
Mercedes-Benz did not pay special attention to the promotion of driver assistance system, but EQC's function in L2 driver assistance is not weak. In addition to the conventional ACC adaptive cruise, automatic car following and other functions, EQC can also realize auxiliary lane change.
EQC can accurately identify the road conditions, and when the left turn signal or right turn signal command is input, it can decisively and quickly judge the road conditions and execute them.
Price consideration
It is generally believed that EQC attracts users who trust Mercedes-Benz and like Mercedes-Benz, and intends to switch from tank trucks to pure trams. The price of nearly 600 thousand makes many people who like him in a wait-and-see state. So recently Mercedes-Benz launched a three-year interest-free installment plan similar to foreign leasing.
In other words, a down payment of 50,000 yuan (actually 49,999 yuan) and a monthly payment of 2,888 yuan will give you EQC3 years. By the end of the three-year interest-free period, users can choose to pay the final payment to buy EQC, or they can choose to buy a new car at the market price of EQC exceeding the final payment.
This can not only solve the concerns of potential consumers about the second-hand value preservation of pure trams, but also solve their concerns about the uncertainty in the future: if there is a better choice after three years, the consumption decision made today is not wrong.
For Mercedes-Benz, they have increased the stickiness with users and gained the opportunity for users to continuously "generate electricity" for the enterprise.
abstract
Automobile electrification is a long road. Just like 125 years ago, when there was a car, innovative engineers made various attempts and had a heated debate on the choice of technology.
There are more and more topics about new energy vehicles, smart cars, technology and development, but consumers and fans still seem to have not reached an understanding. On the contrary, people's cognitive gap on advanced technology is getting wider and wider. Some people are still immersed in the roar of fuel trucks and flowing gasoline to express their feelings, while others are excited about every function improvement of autonomous driving. ...
This reminds me of a sentence by Dickens, a great writer in A Tale of Two Cities: This is the best time and the worst time. People compare the industrial transformation of Mercedes-Benz to the elephant turning around, where difficulties and opportunities coexist. Therefore, Mercedes-Benz encourages itself by this, which is closely related to the theme of this activity "A Tale of Two Cities".
