CTOnews.com, April 8, China FAW held a "meeting Flag Technology-Red Flag New Energy Technology Conference" in Changchun FAW NBD Flag Space and launched the third largest platform under the "Flag" super architecture-Red Flag hybrid platform HMP. Qiu Xiandong, director, general manager and deputy secretary of the party committee of FAW, said that there will be mass production of two complete vehicle products equipped with HMP platform in the second half of this year.

CTOnews.com learned from the official that the "banner" super architecture consists of an electric and intelligent integration platform HME and an intelligent and experiential integration platform HIS. Among them, the research and development of hybrid platform HMP took five years and broke through 526 key core technologies. The four core systems are:

High efficiency hybrid transmission system: the comprehensive efficiency is more than 90%, the output torque of the longitudinal transmission is more than 4500nm, the output torque of the horizontal transmission is 3900Nm, and the global order noise is less than 65 decibels. International pioneer longitudinal dual-motor multi-gear hybrid transmission LDU45, used in C-class hybrid vehicles, to achieve the shortest transmission path and the lowest system loss.

Hongqi has also developed a very compact and efficient horizontal hybrid transmission HDU35, which is used in A-class and B-class hybrid vehicles with the shortest axial length of 376mm in the industry, and adopts medium-voltage silicon carbide inverter and multi-layer flat line oil-cooled motor for the first time to reduce the assembly weight by more than 10kg compared with similar products.

High-performance hybrid engine system: Hongqi has built two hybrid engines, 20TD and 15TD, with the highest thermal efficiency of 44.3% and 45.2% respectively, and can still achieve ultra-high power of more than 60kW / L on the premise of ensuring high thermal efficiency.

Power decoupling electric drive system: under the action of the innovative structure of intelligent disconnect and electric auxiliary drive, the mode of four-wheel drive and two-wheel drive can be switched automatically in 100ms. The Hongqi power decoupling electric drive system can output more than 200kW power, and the rotational speed can reach 18000 revolutions per minute. The latest generation of high-performance customized magnetic steel and multi-layer square conductor technology are adopted to achieve the ultimate small lightweight, the material consumption is reduced by 17%, and the weight is less than 74kg.

High safety and low temperature battery system: the lightweight all-composite box has a strength of up to 1000 MPA and non-brittle material characteristics, protecting the armored structure of the battery when the weight is more than 15% lower than that of the metal box; the resistance to 1000 ℃ high temperature and full insulation forms three-dimensional electrothermal protection, which completely eliminates the risk of short circuit and arc drawing. Hongqi has also developed a low-temperature active cell, which has been tested by the bench. After being shelved for 12 hours under the environment of minus 20 ℃, its available energy is 8% higher than that of the metal box battery, and its power output capacity is more than 25% higher.
