In recent years, as the attention of the new energy vehicle industry continues to heat up, false information and online rumors on topics such as industry policies, vehicle safety, and environmental protection have appeared from time to time, confusing the public, misleading the public, and affecting the healthy and sustainable development of the industry. Starting from December 8, the "Today's Rumors" column will focus on typical rumors and misunderstandings in the new energy vehicle industry every Friday, and strive to clarify fallacies and solve doubts and doubts for the public.
Rumor that new energy vehicles can not be charged in rainy and snowy days?
Truth: Whenever there is heavy rainfall, the topic of "can you charge new energy vehicles on rainy days" is very likely to cause controversy. In this regard, the new version of the "National Standard for New Energy Vehicle Charging Interface and Communication Protocol" issued on December 28, 2015 stipulates that the protection level of the charging gun interface before plugging is IP54, and IP55 after plugging. However, some car owners like to use long power strip flying cables to charge their cars, which is very dangerous on rainy days, so be careful. In addition, there may also be water ingress caused by loose and deformed sealing rubber rings due to non-standard operation, and there will be similar risks caused by snow falling on snowy days, in addition to rainy days. Therefore, it is recommended that you follow the specifications when plugging and unplugging the charging gun, and if conditions permit, try to choose a charging pile that is not open to the air in rainy and snowy weather.

Rumor that "fast charging" is very damaging to the power battery of new energy vehicles?
Truth: New energy vehicles can be roughly divided into two categories: pure electric vehicles and plug-in hybrid vehicles in terms of power sources. Pure electric vehicles have a relatively large battery capacity, and there are generally two charging methods: fast charging and slow charging, while plug-in hybrid vehicles have a smaller battery capacity, and some vehicles are only equipped with slow charging. Fast charging is relative to slow charging, and the degree of damage to the battery depends on the frequency of use. Frequent fast charging may cause some damage to the power battery compared with slow charging, but if the rationality and technological advancement of BMS (battery management system), battery density, materials, temperature, etc. are fully considered in the design and development process of new energy vehicles, it will also greatly reduce the reduction of fast charging for battery cycle charge life. Especially with the deployment of high-voltage platforms and the acceleration of the construction and layout of high-power charging piles, high-voltage fast charging will become an important trend of new energy vehicles.

Myth: Is "goose feather snow" a blizzard?
Truth: Recently, there have been blizzards in many places. Some people think that since it is a blizzard, it must be a very violent "goose feather snow", right? Whether it is a blizzard or not depends on the amount of snowfall and the duration of the snowfall.
The standard for snowfall levels in continental meteorology divides snowfall into seven levels: light snowfall (sporadic light snow), light snow, moderate snow, heavy snow, blizzard, heavy snowfall, and heavy snowfall. The standard generally uses two standards: 12 hours and 24 hours. Among them, snowfall with 10.0 to 19.9 mm of precipitation in 24 hours or 6.0 to 9.9 mm of precipitation in 12 hours is called blizzard. In other words, a blizzard must be a period of accumulated precipitation on the level of a blizzard. The term "goose feather snow" describes the size of the snowflakes rather than the magnitude of the snowfall. The "goose feather snow" we see, if it does not last for a long time, is not necessarily a blizzard, and if the continuous snow we see lasts for a whole day, the accumulation may reach the blizzard or even the heavy snow, and the threat to transportation, energy, agriculture and other fields is greater.

Circular: In November 2023, 18.14 million reports of illegal and adverse information were accepted nationwide
Details: In November 2023, the Whistleblowing Center of the Cyberspace Administration of China (CAC) instructed cyberspace reporting departments at all levels and major website platforms across the country to accept 18.14 million reports of illegal and negative information such as pornography, gambling, infringement, and rumors, an increase of 5.0% month-on-month and 52.7% year-on-year. Among them, the Whistleblowing Center of the Cyberspace Administration of China accepted 641,000 reports, an increase of 9.7 percent month-on-month and 29.6 percent year-on-year, 885,000 reports were accepted by local network information reporting departments, an increase of 23.6 percent month-on-month and 13.9 percent year-on-year, and 16.614 million reports were accepted by major website platforms across the country, an increase of 4.0 percent month-on-month and 56.6 percent year-on-year. Among the reports accepted by major website platforms across the country, the number of reports accepted by major commercial website platforms accounted for 49.2%, reaching 8.168 million.
