Speaking of “bluish” The car Many people may feel strange, it actually is Shanghai GM Buick 6 VELITE Chinese name. Not long ago, Shanghai GM Buick officially announced the creation of someone by the name of Chinese netizens, but also introduced a bluish 410KM version. As the name suggests, light blue version refers to the 410KM NEDC mileage of the new car 410 kilometers, but it is not a large battery pack in 301KM facelift version based on the so simple, but for the entire three-including batteries, motors, electronic control, including systems have been upgraded.
Three full upgrade system
Buick bluish 410KM capacity upgrade version of the battery pack to 52.5 kwh, It uses an energy density of 140 Wh / kg NCM523 three yuan lithium batteries. Meanwhile, the new car also switched to greater power, higher efficiency and wider speed range front permanent magnet synchronous motor, the maximum power of 110 kilowatts, peak torque of 350 Nm middot; m, respectively, compared 301KM lifting plate 25 kilowatts and 95 cow middot; m.
car electronic control system integrates a DC DCDC integration module, and dynamic frequency control technology, the peak efficiency of the whole system reaches 95% or more. Buick official data showed, compared with bluish 301KM version, light blue version of the NEDC 410KM mileage increased from 301-410 km, 0-50 km / h acceleration time from 4.4 seconds to lift 3.6 seconds, a hundred kilometers energy consumption reduced to 13.1 from 13.3 kwh kwh.
Version Buick bluish 410KM also designed independent circulation intelligent battery pack temperature control system. Molten aluminum alloy sheet against water module batteries, the battery pack is placed in the lower end, with a separate outer loop, coolant member pots, pumps, heating and cooling the auxiliary heat exchanger module.
This system not only has an independent temperature control module may dynamically adjust the heating and cooling efficiency of the battery, you can also rely on the pressure and temperature sensors double check, to achieve precise battery monitoring coolant temperature, electrical core temperature was maintained at more suitable working range.
aspects of safety, light blue Buick 410KM version based on the new Energy Star as a forward vehicle architecture developed models, beginning of the design targeted to create an independent high-strength double-frame structure protection, and increase the number of car body style crash beam through design, to enhance crash safety of the battery pack.
EIC system testing standards of new cars is also very strict, not only to go through the puncture, crush, soak, fire, overcharge, over discharge, short circuit, over-temperature, shock, vibration, temperature, shock, heat shock, 13 limit salt spray and other safety inspection, but also increased the railroad tracks, drop test and above the existing national legislation of the lateral column touch test, passed the stringent GM’s global vehicle durability test.
outside protected physical structure, Buick bluish 410KM Edition through Aerospace-grade temperature control nano airgel insulation material as batteries, high pressure dual independent discharge design, battery status, all-weather monitoring and early warning of more than 400 system-level security requirements and measures, battery management system and driving key subsystems meet ASIL D system is the highest safety standards.
design is still very sense of technology
Buick bluish 410KM and 301KM edition version of the model is almost no difference between the front face of micro Blue Series family of mask , from the convergence Logo for flying wing extending from the LED elements Zhanyi headlights, recognizable very obvious. Bluish 410KM extends to the rear of the roof plate, forming a huge interior space, it is positioned official purpose MAV.
Buick bluish 410KM version of the rear license plate frame design bumper position, the tailgate has a lot of blank looks simple and technological sense. Buick bluish 410KM 301KM version of the body size and identical version, length and breadth were 4650/1817/1510 mm, 2660 mm wheelbase.
In the interior, Buick bluish 410KM Edition line follows the suspension elements of the design and the depth of color of the collision. Compared to 301KM version, 410KM unique version also adds cruise control, panoramic sky, suede seat, the main electrically adjustable driver’s seat, front seat heating functions.
commendable that Buick bluish 410KM version of space travel was barely affected by a large battery pack, front and rear ride feel and fuel car close to the floor is not raised, the head is not depressed. Moreover, light blue Buick version 410KM rear central platform also only a very small magnitude of the bulge, while three people will not ride uncomfortable. Trunk floor models as compared to the general fuel is higher, but the full level of the second row seats recline ratio by 4/6, the maximum expansion volume to 1098 liters trunk.
Dynamic excellent, enabling single-pedal driving
the actual driving Buick bluish 410KM version can provide a unique lightweight electric vehicle acceleration feel, you can feel the light pedal timely effective power output. Moreover, thanks to the new wide speed range of the motor, the high-speed power reserve state is not significantly reduced. The same should appreciate that, light blue Buick version 410 to the driver offers a full selection of privileges, such as high / medium / light intensity select three-block kinetic energy recovery, sport / normal / economic select three driving modes, high and low power air conditioning selection, etc., so that the driver can freely mix according to demand.
The kinetic energy recovery switch to strong intensity stopper, after releasing the accelerator pedal will see a noticeable deceleration, then familiar, it may be utilized only the accelerator pedal acceleration and deceleration, and It is often said that the single-pedal driving. In the block can feel involved in the kinetic energy recovery system, and softer than the strong block of interventional procedures, comfort has improved significantly, but most of them need to meet the brakes. Light and fuel stop feeling it close to the car.
Buick bluish version 410KM chassis with McPherson independent suspension, the structure of the multi-link independent suspension, the overall tuning soft, road small bump baseThis can be filtered out in comfort on paved road is more remarkable. But in the intense driving or driving on non-paved road, slightly blue 410KM version of the chassis is still difficult to suppress the vehicle’s inertia is too large, body posture control is not very good. After
Conclusion
Buick version will NEDC bluish 410KM mileage raised to 410 km, and finally filled the previous board’s short life, not only for the city daily use, consumers need daily walk through the suburbs or the occasional long-distance travel demand is also met. Compared to version 301KM, 410KM upgrade version of the price actually only 1.2 million, with models in two new cruise control, panoramic sky, suede seats, electrically adjustable driver’s seat main, heated front seats, etc. If the function is also only 14,000 yuan more than 301KM upgrade version of the same configuration models, very competitive.
