-30 degree extremely cold gallop, Weima M7 directly facing the pure battery exclusion zone!

As soon as the WM M7 was released, it aroused the interest of many people, after all, this is the first private car of the WM family. According to the official response of WM, WM M7 will be mass-produced in 2022, officially mass-produced and listed, according to the current official release of the news, this highly anticipated WM first car is undergoing an extremely cold test.

Every new model in WM must undergo a lot of testing and multiple tests before mass production, and the WM M7 is no exception, recently tested in an extremely cold environment of -30 ° C. Extremely cold weather in the northern region is a situation that may be encountered in the use of cars. During the test, experienced engineers used efficient on-board evaluation technology to record the state of the M7 in extreme cold conditions to ensure that the M7 model after mass production has a consistently pure driving interest.

The M7 also delivered an excellent answer, in the extremely cold environment of -30 ° C, the energy consumption of the WM M7 is 17kWh/100km, and the temperature in the car can reach a comfortable temperature in 17 minutes, and the energy consumption of the air conditioner is less than 10%. At the same time, a number of "freezing" tests were carried out in the -30 °C environment for 12 hours, and after freezing, the cold start was normal, and the charging efficiency from 30% to 80% of the SOC could still be maintained for 30 minutes.

It is understood that the WM M7 is equipped with the third generation of WM Living Motion three electric energy system, its electric drive assembly efficiency of more than 96%, efficient integrated motor mass kilometer density of 2.399kW/ kg. At the same time, the new car also has a battery thermal management system, which adopts two ways: "active heating" and "self-heating during discharge" to keep the battery at a comfortable working temperature. In addition, it can also coordinate the energy consumption management of motors, air conditioners and other accessories, making battery energy allocation more intelligent.
