With the continuous advancement of global energy conservation and emission reduction, the rapid development of new energy vehicles, consumers in the choice of a pure electric vehicle, the mileage has become the primary reference data, but at present, the official calibrated mileage and the real mileage also have a big gap. So, is there an electric vehicle that has the closest mileage achievement rate in practical application scenarios to official data?
The China New Energy Vehicle Endurance Reality Challenge organized by CCPC, a subsidiary of China Automobile Research Institute, gave the answer.
As the "Olympic Games" of the automotive industry, CCPC has created a new model of automobile performance comparison for domestic brands of mass production vehicles, as an important part of the competition format, China's new energy vehicle endurance realism challenge, with the closest to the actual application scenario of the WLC working conditions of the vehicle for real endurance test. With its outstanding endurance performance, Chevrolet Chang tour stood out from the fierce competition and ranked first in the 100,000 to 300,000 new energy model group with a real endurance rate of 77.03%, which once again confirmed the excellent product strength.
In order to ensure the fairness and impartiality of the race, the challenge was performed by professional drivers and referees of the CCPC competition, and the participating vehicles were fully charged before departure, the mileage was cleared, the air conditioning was set to automatic mode, and the temperature was 23 °C. 5G real-time monitoring, transient data guidance and information collection are carried out on the vehicle throughout the event. Chevrolet's 2022 Tour strictly follows the rules of the race, and is tested in a loop on the real road in the low-speed, medium-speed, high-speed and ultra-high-speed sections until the target speed cannot be maintained due to insufficient power. In the end, with its excellent real endurance performance, Chang Tour stood out from the competition and ranked first in the same group.
As Chevrolet's first pure electric intercity coupe, Chang tour has won a good market reputation with excellent pure electric drive technology, intelligent interconnection technology and stable and reliable security technology since its listing. Of course, behind the success of the smooth tour is bound to be inseparable from the blessing of the three electric technology. The high-performance electric drive system has become the core of this car, consisting of a permanent magnet synchronous motor and a high-precision single-stage gearbox, with a transmission efficiency of up to 96%, a light start, no setbacks in speed, and a rapid acceleration response. The maximum power of the motor reaches 130 kW, the peak torque is 265 N·m, and the maximum speed can reach 170 km/ h. It can be said that the data of the motor also directly affects the acceleration of the daily driving of the patrol, after all, the instantaneous torque burst of the electric vehicle is very outstanding, and the feeling of pushing back still has to be there.
In addition, high-performance ternary lithium battery has become the best proof of the authenticity of the battery life, the battery capacity is 61.1kW·h, pure electric driving mileage can reach 518km, according to the real endurance rate of 77.03%, the real mileage of the patrol has reached 399 kilometers, and the Monday charge fully meets the needs of the urban commuting to work. The power consumption of 100 kilometers is 12.6 kWh, which further reduces energy consumption. At the same time, the high-performance ternary lithium battery pack adopts a number of reliable and safe designs, and the intelligent water circulation temperature control system can accurately control the temperature, dynamically adjust the heating and cooling of the battery according to the intelligent algorithm, and ensure that the cell temperature can work normally between -20 °C and 55 °C. Aerospace-grade nano temperature control material aerogel is adopted between the cells, which can withstand high temperatures of 1200 °C, and the anti-thermal diffusion performance reaches more than 10 times the requirements of the national standard. High-performance composite thermal insulation materials are used between battery modules, which can withstand high temperatures of 1000 °C, and have excellent insulation and can withstand high voltages.
Design a high-strength protective frame around the battery pack, a lower anti-collision beam made of 100% high-strength steel, a double-frame structural beam and a number of through-line structural beams, triple physical protection. After a collision, the energy transfer of the battery can be disconnected through the battery management system within 1 second and the residual voltage in the loop can be reduced to a safe range within 5 seconds by a dual independent design.
In addition, Chevrolet Patrol also supports DC fast charge and AC slow charge two charging methods, when the power is close to full, automatically enter the trickle charging mode, small current replenishment, so that the battery remains fully charged, prolong the battery life, fast charge mode, 40 minutes can be charged to 80% (average 15 minutes to increase about 120km cruising range); Chevrolet smart charging pile supports 32A slow charging mode, you can complete the charging within 8 hours. And Chang patrol also enjoys 3 years or 100,000 kilometers of the whole vehicle and 8 years or 160,000 kilometers of the three-electric system super long warranty service.
Of course, Changshuo is also equipped with 3 energy recovery modes, namely lightweight free recycling mode, medium high efficiency recycling mode, and strong empowerment recovery mode, which effectively improves the endurance performance. The three driving modes of ordinary, sports and single pedal allow the driver and occupants to freely choose the driving mode according to different road conditions and driving habits. In congested road conditions and continuous corners, driving is easier, while more energy can be recovered, making cruising more realistic and reliable.
Write at the end:
The current automobile market can be said to be transforming into new energy vehicles, and in the era of continuously high oil prices, new energy vehicles, regardless of car cost or driving texture, are enough to gradually replace fuel vehicles to take over the market. However, the problem of mileage has always been an important factor for car companies to consider, after all, in winter, cold weather has a great impact on the battery, and the mileage achievement rate is also greatly reduced. Chevrolet Cruise can do so well with enough technology to make the endurance real rate so good, which shows that this pure electric model is enough to relieve the current consumers from the problem of mileage anxiety.
