Mobile WebSiteWith the new energy policies of various countries being rolled out, new energy vehicles are bound to be the trend of the future automotive industry. However, in the face of new energy policies, the focus of each country is slightly different; domestic or most countries tend to be pure electric vehicles, while South Korea or a few developed countries prefer hydrogen or other rare fuel sources. Just recently, there is a message about modern NEXO that is in the eyes of the author: its key information charging 500 minutes of battery life for five minutes, no doubt makes the author a little amazing.
01 "Hydrogen fuel" battery, so effective?
After charging for five minutes, it can reach more than 800km of battery life, but the material of the battery itself is not the mainstream lithium battery, it is a hydrogen fuel cell. Why is it so efficient? Take a look at the history of modern cars playing with fuel cells.
In fact, as early as 1998, Hyundai Motor had a dedicated fuel cell technology research center. As a result, the production model ix35 FCEV has been produced before, and it was born in 13 years. It has a maximum life of 594km and a top speed of 160km. In 2015, it has already been recognized by Ward Top Ten. As for the hydrogen fuel cell that can reach 800km in five minutes of charging, it is the latest 120kw hydrogen fuel cell technology, which will be installed on the NEX0. At present, this model has begun to scale up in North America, and it has also received official recognition of this year's "Ward Top Ten".
As for the principle of the technology itself, it is far from the lithium battery. Hydrogen fuel cells actually use hydrogen to react with oxygen in the air in the fuel cell stack to generate electricity and send clean water. If the greenness of hydrogen is ensured, this system can be infinitely cycled. A fairly environmentally friendly new energy technology. At the same time, on the body, in addition to the general fuel cell stack, there is also a hydrogen storage tank for storing hydrogen, which is used to drive the motor and a battery pack that provides energy storage.
The core level of this modern 120kw hydrogen fuel cell technology is what makes me most optimistic. Nowadays, this hydrogen fuel cell has reached an output of 154 horsepower and a maximum speed of 179km/h. Hydrogenation for 5 minutes can achieve a maximum battery life of 800 kilometers, and an integrated hydrogen storage system has been developed to maximize the space; The electric drive and the fuel cell stack have been integrated, and it can be said that the mass production specifications are fully realized.
02 Compared with pure electricity, the difference between the two?
After reading this series about the power of hydrogen fuel cells, how does it differ from pure electric batteries in practical applications or operations? Let's take a closer look.
In terms of daily use, the number of charging piles has begun to spread, and although it is not as large as the number of traditional gas stations, it is also intensively controlled by urban centers. For hydrogenated fuels, it is unreasonable to control the surrounding areas of the community or within the commercial circle. More ways can still rely on traditional fueling stations, and hydrogen fuels, which are more reactive with air, should also be at gas stations. Separate places and so on to ensure safety. At the same time, the cost of hydrogen fuel is now significantly higher than pure electricity and fuel, which is still a big threshold for daily adoption.
In addition, in terms of safety, many consumers will worry whether the bottle and can in the car will make the safety performance of the car extremely poor. In the latest test of the European E-NCAP not long ago, the NEXO participating in the test received a five-star rating, which does not need to be considered. Another key point worth noting is that hydrogen fuel cells can still operate efficiently in extremely cold weather, and the overall performance is better than traditional pure electric vehicles.
In terms of maintenance costs in the later period, the current maintenance mode of hydrogen fuel vehicles is relatively simple and fixed, and the antifreeze and filter elements can be replaced periodically. The reason is that the power system needs excellent temperature control to ensure, so the requirements for antifreeze are extremely high; and for the environmental protection of new energy, the filter element is clean enough to ensure the cleanliness of the intake air. And from the aspect of environmental protection after disposal, the recyclability and handling of hydrogen fuel cells are also higher than those of conventional lithium batteries.
03 How long can the Chinese market see?
That said so much, how long in the domestic market can there be hydrogen fuel vehicles? This is still an unknown number.
As the top car company in the hydrogen fuel market today, Hyundai is still in the promotion stage in the European and American markets, and even the most important North American market has not yet been officially listed. Naturally, there is no spectrum for events entering the Chinese market. However, once these models are officially entering the market, under the blessing of various subsidies, they will inevitably have some impact on pure electric vehicles; however, the practical problems are urgently to be resolved.
Finally
The domestic new energy field is highly developed for pure electric vehicles, ignoring the development of some other new energy fields, and there are some top-heavy meanings. If there is a breakthrough in the rare gas category in the future, it will be a devastating blow to pure electric vehicles. The field of hydrogen fuel has been researched for many years, and the effect is now very significant. New energy trends tend to consumers can also pay more attention to such areas, and maybe the future will be one of your choices.
