No. In the early years, some people filled the batteries directly with well water, boiled water, or even river water. Ultimately, no batteries survived. Shortly after filling, the battery was completely damaged and could not be repaired. .
The main reason is that water contains metal ions. Adding them to the battery will cause serious battery self-discharge. When not in use, the battery will discharge internally. Battery life will be significantly reduced. In addition, it is particularly easy to lose water when loading, and the water is more likely to evaporate. This vicious cycle will significantly reduce battery life.
Distilled water contains almost no metal ions and has extremely high resistance. Therefore, adding it to a large battery will not causes self-discharge of the battery. In fact, the effect of adding distilled water to the battery is the same whether for medical or drinking purposes. They do not all contain metal ions, and the purity and cleanliness requirements for medical use are higher after all, they need to enter the human body.
Note that there is also a large bottle of drinking water which is not distilled water, but pure water. This water is not distilled, but filtered via reverse osmosis equipment. Although it is pure, it contains metal ions.
Wahaha purified water sold around the world is like this. The strength will be lower than that of distilled water. In case of emergency, you can also add distilled water to the battery. However, due to the low resistance, the battery will have internal discharge. There is no problem charging it every day. If left for a while you constBe aware that the battery power is decreasing too quickly. The battery should be recharged in time during storage.
Do you still remember the hydrohydrogen car that “runs on drinking water”? New energy vehicles are another.
In theory, it is possible, but in fact, it is not yet possible to use this technology in production.
First of all: the production of hydrogen gas by water electrolysis is itself an energy conversion process (conversion of electrical energy into chemical energy). We know that energy itself is conserved in this conversion process. some conversion efficiency problem. For example, during the process of electrolysis of water, the current will heat the water and vaporize part of it, which requires a certain amount of energy, which makes the chemical energy (hydrogen and oxygen) obtained lower than the previous electrical energy. When he isused in cars to convert it into kinetic energy, there is a certain conversion efficiency problem. At the current price of electricity, this cost is too high.
In addition, hydrogen itself is difficult to store. To achieve a certain energy density, a certain pressure and adsorption materials are required. Currently manufactured hydrogen storage tanks and hydrogen absorption materials cannot achieve greater energy density. . You can't just let a car pull a big tank and drive down the road like a tanker truck, can you?
So not yet.
In recent years, the huge market potential of new energy vehicles has prompted many automobile manufacturers to conduct research. In addition to the electric vehicle technology chosen by most automobile manufacturers, other niche technologies in terms ofnew energy have not been spared. For example, Youth Cars, which became famous in 2019 thanks to its “hydrogen engine”, then caused an outcry in public opinion due to the principle “you can run if you drink water”.
After two years, the young car, which had not been heard of for a long time, is once again in the public eye. However, this time it did not bring good news as one of its subsidiaries went bankrupt.
Entering bankruptcy liquidation proceedings
According to reports, Jinhua Youth Automobile Manufacturing Co., Ltd. (hereinafter referred to as "Jinhua Youth Automobile Manufacturing Co., Ltd." The interim administrator of "Jinhua Youth Automobile" issued the "Instructions for Claiming Claims in the Bankruptcy and Liquidation Case of Jinhua Youth Automobile", announcing officially that the company has entered the bankruptcy liquidation processe.
I have to say that it's really no surprise that Youth Cars found itself in this situation. Many companies are entering the new energy automobile market, but few can talk nonsense like Youth Auto.
In the "water-hydrogen engine" manufactured by Youngman Automobile, it has the advantage that "hydrogen can be produced in real time from the water on board, and the vehicle does not only needs to add water to ride". However, after this benefit was reported, it was questioned by the majority of netizens.
According to the data, a hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. The basic principle is the reverse reaction of the electrolysis of water. The “hydrogen” fuel used in fuel cells can come from hydrogen produced byelectrolysis of water and any hydrocarbon, such as natural gas, methanol, ethanol (alcohol) and biogas. The cost of hydrogen fuel cells is reported to be 100 times that of regular gasoline engines.
Theoretically speaking, "a car that can run by adding water" is not without scientific basis. But why does the “water-hydrogen engine” of the Youth Car raise so many doubts? The problem is that in the step of transforming water into hydrogen and oxygen, the answer given by Young Car is that it only uses a catalyst. Anyone who has studied chemistry in high school knows that a catalyst can change the reactants (increase or decrease) without changing the chemical balance, and that its own mass and the substance that does not change before and after the chemical reaction are called catalysts. So this doesn't give people a reasonable answer, and the whole report gives us the impression that "it's enought add water and you can run”.
Building a car is not an easy task
In fact, the so-called "water-hydrogen engine" manufactured by Youth Auto Group has actually been questioned. During the new energy vehicle subsidy fraud scandal in February 2017, the website of the Ministry of Industry and Information Technology announced administrative sanctions against seven automobile companies, including Youngman Auto.
Undoubtedly, new energy vehicles and traditional fuel vehicles are not one or the other, and the automobile industry is not only a technical direction of purely electric vehicles , including internal combustion engine vehicles, hybrid vehicles, hydrogen fuel cell vehicles. , and natural gas vehicles. There is plenty of room for technological innovation in many areas. sos when we make carsAt that time, various technologies might not be spared. But building a car isn't easy, nor is it a way to cheat or make money. Only through serious and dedicated research can we truly occupy a place on the automotive road of the future. The end of the “hydrogen car” scam also made everyone realize that it is impossible to build a car easily without real materials.
