With the continuous advancement of three-electric technology, the range of new cars is generally above 400km, and even high-end models of 700km are also numerous, but the concept of "mileage anxiety" seems to be bound to pure electric vehicles and is always lingering. Especially when it comes to the official nominal battery life, everyone will feel that there is always moisture in it and needs to be squeezed.
In the past two days, there is a very interesting test of the extreme range of Zero Race C01. With a nominal range of 717 kilometers, the Zero Race C01, which was launched shortly after it actually ran a very long score of 955 kilometers in the actual test on the road. This is a limitless and "drying" extreme battery life, which makes people suddenly feel that what you Zero Race did? Is it a hasty when giving the Zero Race C01 standard range?
The little secret of the inflated official standard battery life
In the early stages of the development of pure electric models, "milestation anxiety" was the most criticized by consumers and the most concerned issue when buying a car. Therefore, many electric car manufacturers inevitably strive to run far in the test.
21 tests before 2021 are all in accordance with NEDC standards. This is a set of automobile energy consumption testing standards formulated by Europe and is also the most mainstream range standard in China. In terms of practical results, this standard test method is still theoretical. Its test generally takes two methods. One is called NEDC working condition testing, which is actually in the laboratory. The car is tested on a treadmill called "chassis dynamometer". By simulating the road conditions in the urban area and suburbs, the test mileage is completed. Another constant speed method test is simpler. The vehicle conducts a constant speed test of (60±2)km/h, and calculates the mileage and energy consumption rate of the uniform speed state based on the mileage and energy consumption, which is more theoretical.
Since test environment is in a closed laboratory, the car can be free from wind resistance and actual driving environment, and everyone can achieve good theoretical results. However, this achievement does not take into account the characteristics of pure electric vehicles that consume more electricity on highways or in congested urban road conditions, so the NEDC's battery life is quite different from its real battery life. In order to promote the needs, some car companies only mention the mileage obtained through the uniform speed method to further impress the inflated battery life of the car companies.
In October 2021, the new national standard CLTC, which focuses more on stopping and running under medium and low-speed urban operating conditions, is also more in line with the actual operating conditions in China, was officially implemented. Many car companies are a little nervous when switching to the CLTC standard. There are many different opinions about the objectivity of CLTC. Can the new national standards meet consumer needs and demonstrate the true strength of car companies? Objectively speaking, this test standard is more favorable for electric vehicles with kinetic energy recycling and higher efficiency. However, from the example of Zero Racing C01, this standard still cannot reflect the actual working conditions of the car. The nominal 717-kilometer range of Zero Race C01 was tested under the CLTC standard, but the actual test of 955-kilometer range of Zero Race C01 has far exceeded the CLTC score, which is a real good result. What black technologies does
have in Zero Racing C01, which are not fake?
has the key factors that affect the energy consumption of pure electric vehicles, mainly including external resistance such as wind resistance and rolling resistance, and in addition, the energy density of the battery and the working efficiency of the motor. Leapmotor C01 has created a simple and modern high-performance luxury electric sedan through a series of pioneering technical solutions.
In order to improve energy density and optimize motor battery efficiency, Zero Run creatively adopted the world's first "battery-free package" CTC technical solution, directly canceling the battery pack design, integrating the battery, chassis and the lower body, not only reducing weight by 15 kilograms, but also increasing the battery layout space by 14.5%, thereby increasing the overall operating condition endurance by 10%, and increasing the overall torsional rigidity of the car body by 25%, and increasing the lightweight coefficient by 20%. The battery chassis is integrated and greatly improves the vehicle's corresponding speed, bringing 3.66 seconds to zero-hundred acceleration capability to the Zero Race C01.

In addition, the CTC solution also reduces the vertical height of Zero Race C01 by 10mm, making its center of gravity lower and more balanced. Combined with its streamlined dynamic posture, the coupe body, the active air intake grille of the cabin, the hidden door handle, the front wheel choke plate, the cabin lower guard plate, the ducktail design and other 16 aerodynamic design solutions, greatly reducing the resistance coefficient of the entire vehicle, and achieving a 0.226Cd ultra-low resistance leading in the same class.
Zero Race C01 wind resistance is as low as 0.226Cd
Long-range pure electric models not only rely on hardware such as battery motors, but also require an intelligent and efficient battery management system. Zero-Performance C01 adopts the industry's first AI BMS big data intelligent battery management system, which monitors cloud big data in real time, and actively protects the vehicle-side cloud to achieve accurate management of power . In addition, the system can also be based on deep learning of historical big data, realize early warning of faults and achieve OTA upgrades throughout the life cycle, thus providing strong support for long battery life.
We once said that Zero Run also has a deep accumulation in kinetic energy recovery. The Zero-Performance C01 is equipped with a variable architecture oil-cooled electric drive assembly to realize a three-in-one integrated design of motor, transmission, and , and controller. While achieving a high output power of 200kW, it maximizes the recovery of energy efficiency. Between the start and stop, the recovery of energy is fed back to battery life.

During the real test of Zero Race C01, the tester drove from Zhengzhou, Henan via the G45 highway to Langfang . Although the air conditioner was not turned on all the way, he drove at a low speed of about 60 kilometers. With the help of the Zero Race C01's ultra-low resistance coefficient of 0.226, the advantages of pure electric vehicles were maximized. However, the 955-kilometer range that exceeds the nominal 200 kilometers is indeed a surprise.
When we drive on a daily basis, we naturally won’t try to clear the battery life limit so deliberately. Like us in the city, we usually commute within 50 kilometers. In addition, we accompany our family on weekends to travel on a self-driving trip in the suburbs. Even if we drive in a fierce style and commute in a more congested urban environment, we will charge once. Whether it is the actual test of Zero Run C01 C01 or the nominal 717 kilometers, we can also drive for one to two weeks without worry, completely bidding farewell to the anxiety of battery life.
