Hongqi EH7 analysis and interpretation: appearance, control, and battery life are all bright spots
On March 20th, EH7 was officially launched. The new car launched a total of 5 configuration models, with a price range of 22.98-30 9,800 yuan. As the first to use the Qimiao double-wing new energy logo, it adopts a new platform architecture, focusing on the mid-to-high-end market. How about it? Let’s analyze and interpret it.
In terms of appearance, a total of 6 color schemes are available, using a combination of traditional and modern designs.The front face features a closed grille and styled headlights.The side.Adopting a two-tone body and short front and rear overhangs, the design of concealed door handles and large inclination of the rear window also reduces wind resistance. At the rear, a through-type blackened light group is used to echo the front face.
In terms of interior, there are 4 double-spell color schemes to choose from, with a simplified design and not many physical buttonsIt is also equipped with a 6-inch + 15.5-inch dual screen and AR HUD head-up display system, and is equipped with 8155The steering wheel adopts a prismatic design, and the seat adopts an integrated design. It also has mobile phone wireless charging, ambient lights,,, and other configurations.
In terms of space, the length, width and height are 4980, 1915, and 1490 mm respectively, the wheelbase is 3000 mm, the trunk volume is 400 liters, and the positioning is 4 doors and 5 seats. And it is equipped with a 1.96-square-meter panoramic canopy, which covers an area exceeding the second row of seats, with an insulation rate of ≥ 99% and a heat insulation rate of ≥ 80%.
The seat material adopts a four-layer structure of foam + soft foam + skin soft foam + skin, and there is a 100mm slow rebound sponge in the front row. The front seats have 12-way electric adjustment, as well as seat memory, heating and ventilation functions. The rear seat tilt is customized at 25 degrees, giving more adjustment space.
From the power point of view, equipped with 22500r/min ultra-high speed motor. The maximum power of the rear drive version motor is 253 kW, 450N · m, the maximum speed is 190km/h, and the fastest 0-100km acceleration time is 5.8 seconds. The maximum power of the four-wheel drive version motor is 455 kW, the maximum torque is 756N · m, the maximum speed is 190km/h, and the fastest 0-100km acceleration time is 3.5 seconds.
From the battery life point of view, there are three battery packs of 75kwH, 85kwH and 111kwH, and the maximum CLTC pure electric cruising range can reach 820 kilometers. It supports up to 365kw fast charging, and the battery life can reach 215km after 5 minutes of charging. At the same time, it adopts intelligent discharge technology, and the external discharge power is 3kW.
The low temperature and high rate battery system, through high anode material, low temperature and high conductivity, improves the lithium intercalation, reduces the SEI film, and increases the low temperature by 28%. The energy retention rate of the battery at -10 ° C is 93%, and the energy retention rate of the battery at -20 ° C is 85%.
From the chassis point of view, the front virtual kingpin double fork arm + rear five-link chassis suspension system is used, and the lightweight coefficient of the all-aluminum chassis reaches 1.15. Front and rear child and mother tires are also used, and the front wheel narrow tires have light steering and the rear wheel wide tires have stable control. And the drive anti-skid control technology can reduce the driving torque earlier and inhibit the wheel skidding of low-attachment road vehicles.
There is also autonomous continuous adjustable, through multiple estimation of vehicle weight changes, the algorithm is used for load compensation, no matter how the number of occupants changes, the damping force can be adjusted in real time to ensure driving comfort and handling stability. In the elk test performance, the test vehicle speed is ≥ 75km/h, the corner response time is ≤ 150ms, and the angle control accuracy is ≤ 1 °.
Conclusion: There are also many competitors at the same level, such as popular models at the same level, etc., and the market sales and recognition are good. And what kind of performance will it have? We will wait and see!
