At present, the domestic new energy automobile industry has entered a stage of rapid development, but for the general consumer, when purchasing new energy models, there will be various troubles. Taking pure electric models as an example, mileage anxiety is a major difficulty that hinders the choice of many consumers, but in the current pure electric models, the mileage can no longer be the same as in the past. Although the mileage has increased, many consumers have found that the real mileage often does not reach the value declared by the manufacturer when it is actually used.
In the recently concluded 2022 CCPC China New Energy Vehicle Competition and Actual Road Endurance Real Rate Challenge (WLTC Condition Method), Chevrolet Chang patrol ranked first in the 100,000 to 300,000 new energy model group, while the Xiaopeng P7, which is priced higher and has the longest nominal endurance, ranked last in the same group.
The closest to actual driving WLTC conditions shows the leading edge
Founded in 2015, the China Mass Production Vehicle Performance Competition (CCPC) is a national event jointly launched by China Automobile Research Center Co., Ltd., a wholly-owned subsidiary of China Automotive Technology and Research Center Co., Ltd., and the China Automobile and Motorcycle Sports Federation, known as the "Olympic Games" of the automotive industry, which makes the event have a strong professionalism and authority, and creates a model of automobile performance comparison.
As an important part of the CCPC series of events, the China New Energy Vehicle Competition and the Actual Road Endurance Real Rate Challenge use the WLTC working conditions closest to the real use scenario to conduct real endurance tests on the participating vehicles. In the course of the challenge, in order to ensure the authority and fairness of the race, there are CCPC new energy competition professional drivers and referees to participate in the execution, and the participating vehicles are fully charged before departure, the mileage is cleared, the air conditioner is set to automatic mode, the temperature is 23 ° C, and the cycle test is carried out in the low-speed section, the medium-speed segment, the high-speed section and the ultra-high-speed section on the real road, until the target speed cannot be maintained due to insufficient power.
Under such strict competition standards, Chevrolet Cruise finally won the 100,000 to 300,000 new energy model group championship with its excellent endurance performance.
Focus on new energy for 27 years, leading technology takes into account both low power consumption and high safety
Chevrolet Chang tour was able to win the championship in the harsh competition conditions and beat the three popular models of Nezha U Pro, Eian S Plus and Xiaopeng P7, which stemmed from its own outstanding strength, especially the advanced technology of the three-electric system. Although GM is a traditional automobile company, it has been focusing on the field of new energy for 27 years and has accumulated rich experience in research and development and manufacturing. The Chevrolet Patrol is based on GM's new electric vehicle architecture for development, so it is equipped with many advanced technological achievements.
Chevrolet Patrol power is equipped with a high-performance electric drive system, consisting of a permanent magnet synchronous motor and a high-precision single-stage gearbox, of which the maximum power of the motor is 130 kilowatts, and the transmission efficiency of the electric drive system is as high as 96%, and the comprehensive power consumption is 12.6kWh/100km.
In addition to the low loss of the electric drive system, the battery system of the patrol is also very durable, which adopts a high-performance ternary lithium battery pack with a capacity of 61.1 kWh and an official cruising range of 518 kilometers.
The low loss of the electric drive system and the durability of the battery are the basis for the performance of the long cruising range. In addition to the advantages of hardware, Chang Patrol also adopts an exclusive brake energy recovery system, which can intelligently distribute mechanical brakes and electric brakes, when the driver gently presses the brake pedal, the brake braking force is all provided by the motor anti-drag, and the maximum speed of the vehicle when decelerating is converted into electrical energy stored in the battery pack, reducing energy waste. Brake braking power is provided by mechanical braking only when the driver re-presses the brake pedal or brakes urgently. The advantages of the brake energy recovery system for pure electric vehicles are obvious, only in the middle range of energy recovery, the vehicle mileage can be increased by 23%, which has played a good auxiliary role in improving the cruising range.
Due to the structural characteristics of the ternary lithium battery pack, it can only play its due performance in the appropriate operating temperature range, and the safety of the battery pack will be higher at this temperature. Based on this concept, the high-performance ternary lithium battery system equipped by Chevrolet Chang patrol adopts intelligent water circulation temperature control system, aerospace-grade nano temperature control material, high-performance composite thermal insulation material and balanced pressure relief valve quadruple design to control the battery temperature, so that the battery is always in the most suitable working temperature, which can reduce battery attenuation, make the power output more efficient, and further enhance the safety of the battery system.
Among them, the intelligent water circulation temperature control system equipped with Chang Patrol can accurately control the temperature, and can dynamically adjust the heating and cooling of the battery according to the intelligent algorithm to ensure that the battery temperature can work normally between -20 °C and 55 °C, whether it is in the extremely cold weather in the northern winter or the hot summer weather in the south, the chang patrol can reduce the battery attenuation to a minimum. In addition, in terms of vehicle safety, most of the spontaneous combustion incidents of new energy vehicles that have attracted much attention from consumers are related to the overheating of the power battery system, and the quadruple design adopted by Chang Patrol can undoubtedly kill the risk of spontaneous combustion in the cradle, which can make consumers more assured to drive the vehicle.
Not only has high safety at the structural design level, the high-performance ternary lithium battery system equipped with Chang patrol has also passed the routine limit test of 7 categories 13 such as puncture puncture, extrusion, fire, overcharge, and short circuit with excellent results before loading. In addition, to further verify its safety, the battery is also involved in rail, drop and transverse column collision tests above regulatory requirements, as well as the verification of insulation, leak detection and flip tests for intelligent water circulation temperature control systems. With the support of more than 400 battery parts-level software tests and software control measures, the battery pack has been rigorously verified, not only can easily cope with the possibility of common damage, in some uncommon damage cases, the battery pack can also ensure safety, enough to dispel consumers' concerns about battery safety, plus Chevrolet also provides a sincere vehicle for 3 years or 100,000 kilometers and three-electric system 8 years or 160,000 kilometers of ultra-long warranty services. Eliminate the worries of using pure electric vehicles for consumers.
Write at the end
For the current new energy vehicles, intelligent technology configuration is important, but these are only the parts that add luster, as a car, the driving experience is the basis for judging whether a car is excellent or not. For pure electric vehicles, the real mileage will be directly linked to the consumer driving experience. Winning the 2022 CPCC China New Energy Vehicle Competition Real Rate Challenge using the harsh working conditions of the WLTC is enough to prove the real endurance performance and outstanding technical level of Chevrolet Chang's leading level of patrol.
Of course, the strength of Chevrolet Patrol is not limited to the power system, its comprehensive strength is also excellent, especially in terms of technology configuration, Smooth Patrol is equipped with 8-inch LCD instruments and 10.1-inch central control screens, and built-in a new generation of MyLink+ intelligent vehicle interconnection system and a new generation of OnStar intelligent car connection system, with CarPlay/CarLife mobile phone interconnection system, as well as NetEase Cloud Music, Koala FM and other Apps, plus a more complete active and passive security configuration, Such a rich configuration performance is very rare for the Chevrolet Patrol, which is priced at 159,900-187,300 yuan, and can well meet the needs of consumers.
Such a real performance undoubtedly provides more peace of mind for every consumer who chooses Chevrolet To cruise, in which you may find it difficult to feel "mileage anxiety", suddenly out of power, halfway anchor? On Chevrolet Patrol, there is no one.
