Research and development of lithium battery vehicles -Lithium - Ion Battery Equipment
Two echelons have been formed in the research and development of fuel powered lithium battery vehicles
In recent years, the cost, starting performance, hydrogen production and hydrogen storage and other key technical bottlenecks faced by the development and application of fuel powered lithium battery vehicles have been continuously broken through, and have begun to enter the industrialization stage.
In terms of fuel powered lithium battery cars, there are basically two echelons in the world. The first echelon is led by Toyota, and also includes multinational automobile companies such as Nissan, Honda, Hyundai, Mercedes Benz, and General Motors. There are plans to industrialize fuel powered lithium battery vehicles by 2020. In the second echelon of automobile companies, SAIC Group's technical level is currently at the forefront.(Lithium - Ion Battery Equipment)
Toyota's latest fuel powered lithium battery car Mirai (which means "future" in Japanese) is equipped with a fuel powered lithium battery system with a total power of 114 kilowatts. It uses a 70 MPa high-pressure hydrogen tank to fill up the hydrogen in three minutes and has a driving range of 700 kilometers. In terms of hydrogen security, Mirai uses a shell made of special materials to enable the hydrogen tank to withstand light attacks. In addition, the hydrogen storage tank has passed very strict local fire test, impact test and drop test. The fire resistance and fall resistance meet the requirements of global technical rules for high-pressure hydrogen storage tank, ensuring the safety of hydrogen storage. In terms of cold start at low temperature, a series of technical problems have been overcome and the start at minus 30 ℃ has been successfully realized. In terms of cost control, compared with Toyota FCHV adv in 2008, Mirai's cost decreased by 95%. In 2015, Mirai's selling price was 7.236 million yen (about 420000 yuan), and the actual selling price in Japan after receiving government subsidies was about 5.2 million yen (about 270000 yuan). To sum up, the world leading level represented by Mirai, whether from the perspective of low temperature starting performance, safety, driving range, or vehicle cost control, fuel powered lithium battery vehicles have been fully capable of competing with traditional internal combustion engine vehicles.
Hyundai has also announced its first fuel powered lithium battery vehicle, ix35, in 2013. The vehicle has passed tests under various environmental conditions and is currently sold by lease.
In 2014, Audi Automobile Company announced the fuel powered lithium battery vehicle A7 Sportback tron, which has a driving range of more than 500km and a maximum output power of 170kW.
In January 2013, Nissan, Daimler and Ford announced the joint development of a new fuel powered lithium battery system and accelerated the marketization of fuel powered lithium battery vehicles in the next decade. Daimler recently said that it is expected to launch fuel powered lithium battery vehicles with competitive prices in 2017.
In China, during the "Innovation Journey - New Energy Vehicles Traveling Ten Thousand Miles" event held in September 2014, the Rongwei 750, a fuel powered lithium battery vehicle independently developed by SAIC Motor Corporation, successfully challenged the humid coastal, extremely cold plateau, humid and hot south, and dry north climate environment, and fully tested its environmental adaptability, but there is still a certain gap to successfully enter the market.
Serious shortage of hydrogenation infrastructure construction
Similar to the charging infrastructure problems faced by battery electric vehicles, the development of fuel powered lithium battery vehicles also faces a serious shortage of hydrogen refueling station infrastructure. According to statistics, the construction of global hydrogen refueling stations entered a new stage in 2015, with 54 new hydrogen refueling stations. As of January 2016, there are 214 hydrogen refueling stations in operation worldwide.
