Open the file, the beginning part is still very correct. After all, the emissions and pollution of pure electric vehicles are much better than those of conventional fuel vehicles, especially in the case of station use, which is a good protection for the health of the surrounding staff. At the same time, "winning the blue sky defense war" is a political task, and there is nothing to question.
Secondly, there are various principles and requirements related to safety and emergency, as well as the general outline of corresponding management measures. This is also the writing standard of documents and the fixed format to convey the spirit, which belongs to the prescribed matters in the prescribed actions and is indispensable. At the same time, it expresses the importance of safety work in the text, which is completely correct and has no objection.
But when I saw the specific operation and requirements, I was shocked. The words between the lines not only reveal amateurs, but also show that the drafters don't even understand the most basic common sense of new energy vehicles.
For example:? Emergency Plan for Battery Failure Events of New Energy Vehicles. Drivers of new energy vehicles should pay special attention to the high temperature alarm and battery compartment during driving. If it is found that the temperature of one battery exceeds the safe temperature, they need to check the temperature of the adjacent battery. If the temperature difference is greater than 5℃, they need to stop and open the battery box cover to check the battery. If the battery compartment smells or smokes, it should be handled according to the vehicle operation procedures, and it should not be handled blindly ... "
There are several "slots" worth talking about in this passage: First, drivers are required to pay attention to the high temperature alarm and battery compartment during driving. The original text says, "Drivers of new energy vehicles should pay special attention to the high-temperature alarm and battery compartment during driving. If it is found that the temperature of one battery exceeds the safe temperature, they need to check the temperature of the adjacent battery. "
We know that no matter what brand of pure electric vehicles, especially small passenger cars, the power batteries are a whole, most of which are installed on the chassis of the vehicle, and some cars also occupy the space under the back seat or the bottom of the luggage compartment, but they are all fixed and sealed. Even the replaceable battery models of Weilai or Beiqi New Energy are locked on the chassis by bolts or bayonet. Excuse me, how can I get the driver to open a whole battery pack? What do you think of the temperature difference between different batteries inside? And what's the point of "checking the temperature of adjacent batteries"? Is there an essential difference between one fire and two fires?
To say the least, there is no battery compartment that can be opened at all. Who came up with the idea that the temperature difference is greater than 5℃? Let's not talk about this nonsense. Let's say that the temperature difference of 5 degrees is within a safe and reasonable range, not to mention that the temperature difference of the battery cell is 5 degrees, which is just the battery pack of some unilateral liquid cooling systems. The upper and lower ends of the battery cell itself will also have a temperature difference of several degrees, which is completely normal.
Therefore, just reading this passage, it can be clearly seen that the framers of the document have no understanding of new energy vehicles at all, even the most basic common sense.
Let's take a look at the more sinister regulations behind: "(3) Open the battery compartment cover, pull the battery box out of the car body, and try to keep the battery away from the car body. When operating, pay attention to the battery box being bruised when sliding out; (4) After the battery is pulled out, try to isolate the car from the battery? 5m？ Outside. "
God, what the hell is a "battery cover"? What the hell is "pull the battery box out of the car"? The driver is required to lie prone under a smoky vehicle that may explode at any time, use a wrench to manually unscrew more than a dozen bolts tightened by machines on the production line, then remove multiple high-voltage cable interfaces and monitoring data lines, and finally pull the power battery pack weighing hundreds of kilograms out of the car body by hand? And try to isolate it 5 meters away? Do you think drivers are all hulk hulk?
It can be seen that the drafters of the provisions simply don't understand the basic structure of new energy vehicles, especially pure electric vehicles. In their minds, they think it is the lead-acid battery of battery cars. But even the big lead-acid battery of the old scooter is heavy. Try taking one with your bare hands. Have you ever seen a merchant who changed the 12V small battery in the auto parts factory? Shoveling the battery with a trolley is really heavy.
The even more incredible clause is this: "If public security firefighters arrive, try to stop them from washing the battery with water. Prevent the battery from burning due to the short circuit of a larger battery. " You're going to rebel!
Let's not say that the simplest and most effective way to deal with the out-of-control fire of power battery at present is to spray it with a lot of water to help cool down and prevent the accident loss from further expanding, that is, to let the fire brigade wash it with fire hydrants. Just letting the driver "try to prevent him from charging the battery" is enough for the driver to eat in prison for several years. At the scene of the fire, anyone must unconditionally obey the command and arrangement of the fire brigade. Firefighters there are spraying water with faucets. How dare you, a driver, stop the water anyway? Cuff them to the ground and put them in a police car.
After reading these "big slots", the following article is like Article 22? Do not open the door or start the vehicle power supply when charging. This irrelevant "nonsense" requirement did not inspire me to vomit. Not to mention that opening the door when charging is the common sense and daily behavior of many ordinary new energy owners. Many cars can connect electricity, use air conditioning and warm air when charging.
As for article 18? It is forbidden to walk or stay in the charging area during charging. In my eyes, it has become a little reasonable. After all, walking around being touched by the charging cable is also a work-related injury and a production safety accident. Therefore, understanding and understanding are strictly required.
To sum up, it is better to invite professionals to do professional things. In particular, managers should make corresponding management and specification requirements on the premise of having a basic common sense understanding of new things. Why don't you ask the driver to dismantle the smoking power battery by hand? Why not tell him to break the big stone in his chest!
