Since 1990, various countries have been developing hydrogen energy vehicles. Toyota Mirai, Honda Clarity and Hyundai NEXO are the three representative models. For future new energy vehicles, Toyota has been focusing on hybrid and hydrogen energy, but has little interest in pure electric vehicles. As early as 2014, Toyota's first hydrogen energy model Mirai was launched, and the distribution industry paid attention to hydrogen energy.
A few days ago, Toyota's new generation of Mirai official images were released. The new car is positioned as a hydrogen fuel model. It is built on a rear-drive platform and has a coupe-style appearance. It will be equipped with three hydrogen storage tanks and has a cruising range of up to 650km. , the new car will be officially launched in 2021.
The second-generation Mirai adopts a dynamic coupe design. The "big mouth" shaped front grille is similar to the Asian dragon style. The shape of the new car has become longer, wider and lower. The position of the front logo has changed. Under the hood, with sharp headlights, the front face is very futuristic.
Looking from the side, the design style of the second-generation Toyota Mirai coupe is very obvious. The 20-inch multi-spoke wheels and low body design make it full of side impact. In terms of body size, the length, width and height of the second-generation Mirai are 4975/1885/1470mm respectively, and the wheelbase is 2920mm. The size of the new car is close to that of the Asia Dragon, and the seating space is relatively comfortable.
The rear of the second-generation Toyota Mirai adopts a through-type taillight design. The simple lines are consistent with the front face, which is also the current mainstream direction.
The interior center console shape of the second-generation Mirai is also the latest design, showing similarities with Lexus. An 8-inch digital instrument cluster + a 12.3-inch multimedia system, in addition to a very avant-garde streaming rearview mirror and a 14-speaker JBL sound system. At the same time, leather wrapping is used on a large area, and the overall texture is full. In terms of decoration, the second-generation Toyota Mirai also adopts the latest design style, which is dynamic and has a sense of technology.
The Toyota Mirai powertrain is a hybrid powertrain with fuel cells as the main power. Like a gasoline engine in a mild hybrid car, the Toyota Mirai's fuel cell stack provides most of the power, and the stack usually stops running when the Mirai is stationary.
The second-generation Mirai power system has been upgraded, adding a newly developed FC unit, improving the performance of the fuel cell system and increasing the capacity of hydrogen storage. The cruising range has been increased by 30%. The maximum power of the drive motor is 134KW, the maximum torque is 300N·m, and the vehicle’s top speed is 175km/h. The chassis design comes from the Lexus GS chassis.
The new car will be equipped with three hydrogen storage tanks. Regarding vehicle safety issues, hydrogen fuel car hydrogen storage tanks, Toyota uses carbon fiber + Kevlar composite materials. In the simulation experiment, the hydrogen tank deformed. It will not leak or explode, so there is no need to worry about safety. It can block the attack of light firearms. Unless you use a sniper rifle of .50 caliber or above to fire continuously, it will not be able to penetrate the hydrogen storage tank.
The biggest highlight of Mirai is its power system called TFSC (Toyota? FC? Stack), which converts the chemical energy generated by combining hydrogen and oxygen into mechanical energy, so Mirai power is still Produced from electric energy, Mirai is more environmentally friendly than traditional electric vehicles.
The second-generation Mirai has been upgraded in appearance, power, configuration, etc. Hydrogen energy vehicles have many constraints, such as high cost and high price, few hydrogen refueling stations, weak infrastructure and other factors. All of them have caused a lot of difficulties in promoting new cars.
Domestic fuel cell technology is also gradually advancing. SAIC has insisted on R&D investment since 2001. Its core technology is comparable to that of international giants. It has obtained 511 patents related to the fuel cell field and actively participated in the formulation of 15 National standards for fuel cells.
In June 2018, SAIC Group established Shanghai Jie Hydrogen Technology Co., Ltd. to integrate core resources such as technical talents in the fuel cell field and accelerate the research and development of independent core technologies.
In 2019, SAIC Maxus FCV80 fuel cell vehicle launched commercial operation in Wuxi, serving the passenger line from Shuofang Airport to Jiangyin Passenger Terminal; this year, the first fuel cell MPV model - SAIC Maxus MAXUS was released. The EUNIQ?7 fuel cell vehicle is equipped with the PROME?P390, the third generation fuel cell system of Jet Hydrogen Technology. It can complete hydrogenation in 5 minutes and has a comprehensive cruising range of 605 kilometers.
Since 2016, Great Wall Motor Group has listed hydrogen fuel cell development as a key project of the group, targeting the world's cutting-edge key technology fields of hydrogen fuel cells, and developing platform-based parts for the passenger car and commercial vehicle markets. Design,? So far, it has invested a total of 1.57 billion yuan of its own funds in product development.
Weishi Energy, a subsidiary of Great Wall Holdings, focuses on the research, development, manufacturing and sales of hydrogen energy technology. After five years of exploration, it has successfully applied for 363 key technology patents in the field of hydrogen energy and fuel cells. In 2021, fuel cell SUVs will be mass-produced.
