As a revolutionary product of "intelligence, comfort and diversity", relying on the "ceiling" level hardware configuration including 3 lidar and 1016TOPS self-driving chips, M7 has a top intelligent driving experience that surpasses its peers. The test results shown by the M7 in the extremely cold environment of -30 degrees Celsius this time once again show the hard strength of the "tram learning bully" in the core fields such as sandian.
The WM M7 conducts harsh extreme cold tests that far exceed the standards of the user's daily use environment
-30 °C, 100 km energy consumption is only 17kWh, driving reliable, comfortable to use
Topics such as poor battery life and slow charging of electric vehicles in winter have been repeatedly pushed to the public. Starting from the actual needs of users, M7 is equipped with a low-attenuation and long-lasting power battery and equipped with a mature thermal management system, which can provide better battery life and more efficient charging experience. In the extremely cold environment of -30 °C, the energy consumption of the M7 test is only 17kWh/100km, which effectively solves the problem of users in alpine areas with a sharp reduction in winter car life.
At -30°C, M7's energy consumption per 100 km is only 17 kWh
In the cold environment, the performance of the battery cell declines, the battery output becomes weaker, which will lead to the vehicle "can not be strong", a reliable performance of the "warm baby" is particularly important for electric vehicles, the battery thermal management system to assume this role. M7 battery thermal management system adopts a strongly scalable distributed architecture, which adopts two ways: "active heating of thermal management system" and "self-heating of the battery during discharge" so that the battery is always in a comfortable working area to ensure normal charging and discharging performance. M7 battery thermal management system adopts high-precision SOC algorithm strategy, which can control the error within 5%, show the mileage more accurately, reduce the user's psychological anxiety, and give more sense of security. At the same time, the M7 battery thermal management system can also carry out more intelligent energy consumption coordination management of motors, air conditioners and other accessories, and when users need to drive with high power, they can fully give battery energy to the motor for output, and the battery energy allocation is more intelligent.
M7 electric drive assembly efficiency of more than 96%
At the same time, the M7 is equipped with a "small and fine" high-efficiency integrated motor, and its electric drive assembly efficiency is more than 96%, which makes the ultimate use of battery energy. It is worth mentioning that the mass power density of M7 high-performance motors reaches 2.388Kw/kg, which is at the leading level in the industry. The motor also meets the needs of use in harsh environments and is designed for a service life of up to 15 years. Based on the third generation of Living Motion power domain control, M7 sets up five driving modes of champion, comfort, energy saving, snow, and adaptive, and the driving sense is finer and finer, meeting more subdivided driving preferences. The comfort mode can provide the same driving experience as the fuel car, so that the "old driver" of the oil car has no sense of switching. The snow mode is to realize the joint commissioning of various components, effectively coping with common winter car scenes such as ice starting and snow climbing.
-30 °C, 17 minutes away from the car, comfortable temperature, enjoy reliable and pleasant travel
Earlier, for electric vehicle users, the realization of "air conditioning freedom" in winter was extremely luxurious. This is not only because of the problem of the heating speed of the air conditioner, but also because the high energy consumption of the air conditioner has led to a significant reduction in the mileage. With the continuous change of air conditioning technology, this phenomenon has changed a lot.
The M7 is equipped with intelligent dual-zone automatic air conditioning, integrated PM2.5 monitoring, negative ion air purifier, fragrance and other functions, creating a comfortable and healthy riding space for users. The M7 air conditioning system has also undergone commissioning work in different seasons of "spring, summer, autumn and winter", in different altitude environments of plains and plateaus, and has been specially optimized for extremely hot and cold weather. When the air conditioner is activated in the normal season and environment such as spring and autumn, the temperature in the car can be maintained in the comfortable temperature range of about 22 ° C for the head and about 33 ° C for the feet in 5 minutes. Especially in extremely hot and cold environments, this comfortable temperature can be reached in 17 minutes, and the air conditioning performance is outstanding.
Just like the "frequency conversion" function of home air conditioners, M7 thermal management system will also accurately control the temperature of air conditioning power based on the system status such as ambient temperature, battery temperature and user's personalized settings, whether it is summer or cold, it can bring you a comfortable and consistent temperature experience. Users can also remotely control air conditioning, intelligent defrosting, remote ventilation, battery temperature control appointment and other functions through the mobile app.
The alpine environment is comfortable for 17 minutes, and the warm air can be turned on in winter
M7 is like a "water master", its air conditioning system achieves an excellent balance between temperature regulation and energy consumption. Through the optimization of algorithm and calibration matching, M7 realizes the efficient cooperation of various executive components such as cold and warm dampers and medium temperature, and different working modes adapted to different seasons and different environments. In winter, the M7 achieves a great improvement in heating energy efficiency by increasing the opening of the cooling and heating dampers and reducing the temperature of the medium. The data shows that in the conventional environment, the energy consumption of M7 air conditioners accounts for only 3%, and in extremely hot and cold environments, the energy consumption of M7 air conditioners is less than 10%, so that users no longer make multiple choice questions with winter cars.
In addition, the M7 also adopts intelligent breathing grille design, in colder environments and high-speed driving, the grille will automatically open and close to meet temperature and aerodynamic requirements, so that the driving experience and endurance performance to further improve.
-30 °C, from 30% to 80% charging takes only 30 minutes, the quality is reliable, travel is not discounted
The environment of minus tens of degrees is a very extreme use environment for both smart electric vehicles and fuel vehicles. How to ensure that the M7 works normally in this environment - charging "no discount" and power "not pulling down" is another core issue of WM engineers. M7 has gone through 3 famous winter calibration test sites (chambers), spanning the ambient temperature from 5 °C to -40 °C, and fully matching various demanding use scenarios of users with more than 150 calibration and test items, from software and hardware to calibration, to create excellent product quality.
At -30°C, it takes only 30 minutes to charge from SOC 30% to 80%.
For core components such as batteries, M7 has conducted a number of "freezing" tests for 12 hours in a -30 °C environment, and the thermal management ability, battery pack thermal insulation performance, endurance and charging and discharging ability at low temperatures have undergone the most stringent tests. After "freezing", the M7 vehicle starts cold and normally, and the thermal management system can work normally and efficiently. At the same time, the SOC from 30%-80% charging time only takes 30 minutes, truly achieving zero anxiety in winter charging.
There is only one test standard for the power system, and it is also the most stringent one: the electric drive assembly of the M7 should be consistent with the performance of the normal temperature environment, and the performance is not discounted. The power and torque output are normal, and the torque response time is less than 80ms. It can also cope with the needs of rapid acceleration and climbing.

In order to ensure the timely delivery of products, WM engineers overcame various unfavorable factors to actively carry out vehicle calibration and testing work, and even the cold winter could not stop the engineers' pursuit of extreme product strength. Next, M7 will also undergo multiple rounds of rigorous testing, and strive to become a representative of the quality of intelligent electric vehicles, creating a smart, convenient, relaxed and pleasant travel experience for users. WM M7, live up to expectations!
