While the market is still concerned about pure electric vehicles, Japanese Toyota and Honda, as well as Hyundai Korea, are focusing on hydrogen fuel cells.
If you attended the China International Import Expo(CIIE) in Shanghai last year, you will find that Honda, Honda and Hyundai's booths are all technologies in this field.

Maybe you have no confidence in hydrogen fuel and are still optimistic about the pure electric direction? It doesn't matter, because the core technology of electric vehicles comes from lithium batteries. At present, the leading manufacturers of lithium battery technology in the world are Panasonic, Sanyo, LG Chem and Samsung, except Contemporary Amperex Technology Co., Limited, which ranks second in supply.
that is to say, Japanese and Korean companies basically have an attitude of "eating in the bowl and watching in the pot" about hydrogen fuel and pure electricity technology.
Hydrogen fuel cell truck jointly developed by Toyota and Hino
In these two days, Toyota and Hino decided to jointly develop heavy fuel cell trucks, and promote their practical use through "driving demonstration experiments" in the future.
In fact, Toyota and Hino have positioned "hydrogen" as an important energy source in the future early in the morning. They have more than 15 years of research and development experience since they jointly conducted an empirical experiment on fuel cell buses in 23.
Toyota and hino are a family, but Toyota focuses on passenger cars, and its sub-brand hino is the representative of commercial vehicles. The heavy fuel cell truck jointly developed by * * * is based on Hino Profia, but it will still adopt a specially designed chassis to adapt to the structure of the fuel cell truck and be completely lightweight to ensure sufficient load capacity.
As for the power of the hydrogenated Toyota Mirai
, two sets of hydrogen fuel cell stacks newly developed by Toyota for the next generation Mirai are adopted, and Hino's strong point technology-the vehicle driving control system applied to the hybrid technology of large vehicles.
The current Toyota Mirai is the first generation product, and at the 219 Tokyo Auto Show, Toyota released the concept car of the next generation Mirai fuel cell electric vehicle (FCEV).
the second generation Mirai is completely redesigned, with a larger cruising range, and the goal is to increase by 3% compared with the current generation.

Toyota, Hyundai and Bosch are all laying out commercial hydrogen fuel cell vehicles, because environmental protection puts great pressure on the commercial vehicle field, and it is necessary to find new technological breakthroughs as soon as possible. The lithium battery pure electricity technology, which is generally optimistic about passenger cars, is not suitable for long-distance commercial vehicles.
trucks or buses need a high cruising range, while ordinary lithium battery electric vehicles have to push dozens of tons of load to reach a cruising range of several hundred kilometers, and the battery weight will become too amazing, making it unsuitable for this field. At this time, the technical advantage of hydrogen fuel cell, which can complete hydrogenation in 5 minutes, is very obvious.
For example, both Toyota and Hino believe that heavy trucks like Hino Profia, which are used for trunk transportation, have enough cruising range, load capacity and fuel supply in a short time, and fuel cell vehicles that use hydrogen with high energy density as fuel can meet these needs.
another important reason why hydrogen fuel cell technology is easy to popularize in commercial vehicles is that the driving route of commercial vehicles is relatively fixed, which is friendly to the construction of hydrogen refueling stations.
the driving cost of Toyota Mirai is close to that of a fuel car
There is no doubt that the cost of hydrogen fuel is still very high (the price per kilogram in Europe is generally more than 5 euros), but it is expected to decrease after mass production in the future, and the energy density of hydrogen is very high, and 1 kilogram of hydrogen can generate the energy equivalent to that provided by about 3 liters of diesel.
Toshiba solar hydrogen production plant in Japan
Japan mainly develops solar and wind hydrogen production technologies, and with government subsidies, the driving cost of Toyota Mirai is close to that of gasoline vehicles. Japanese companies have mastered 83% of the patents of global hydrogen fuel cell technology and are in a leading position.
both Toyota and hino have proposed to significantly reduce CO2 emissions during driving by 25. therefore, it may be the only way to make every effort to promote technological research and development and popularization of electric vehicles, and hydrogen fuel cell trucks are also one kind of electric vehicles.
