At present, new energy vehicles are accelerating the encroachment on the market of traditional fuel vehicles. The market penetration rate of new energy vehicles in the first 11 months of 2021 reached 12.7%, which was a significant increase compared with the penetration rate of 5% in 2020.
But do new energy vehicles really reduce carbon? At present, China's thermal power generation accounts for about 70%, "if the energy structure does not change, the blind expansion of electric vehicles is to increase carbon emissions, not reduce carbon emissions." Liu Ke, a foreign academician of the Australian National Academy of Engineering and dean of the School of Innovation and Entrepreneurship of southern university of science and technology, once said so.
Under the dual carbon target, electric vehicles and hybrid vehicles should develop in parallel, and the carbon reduction value of hybrid power should not be ignored because the development momentum of electric vehicles is good.
Moreover, at this stage, compared with pure electric vehicles, hybrid vehicles have obvious advantages over fuel vehicles. Because it does not need to install charging infrastructure, the user's driving habits do not change much, there is no mileage anxiety, and the power reliability is strong under extreme conditions such as high temperature and high cold, which can meet the needs of users in different regions.
At a time when traditional fuel vehicles still dominate the market, exploring a variety of technical routes is conducive to the early realization of the dual-carbon goal of the automotive industry. Hybrid is by no means a transitional technology, but an indispensable technology route for the automotive industry to achieve its goal of carbon neutrality.
At present, GAC, BYD, Changan, Geely, Chery, SAIC, Dongfeng and other car companies have launched their own hybrid technology routes to accelerate the layout of hybrid technology and products.
On December 12 this year, GAC Trumpchi's new second-generation GS8 was listed, priced at 186,800-246,800 yuan. The new car launched two power options, the Pilot Series and the Dual Engine Series, of which the Twin Engine Series is the first Chinese brand model equipped with Toyota THS Hybrid Technology, opening a new era of Trumpchi Hybrid.
GAC Trumpchi has brought world-class hybrid technology to users, which not only grasps the current consumer demand for cars, but also conforms to the trend of industry development.
Two hybrid paths go hand in hand
On November 19, at the Guangzhou Auto Show, GAC Group announced the "Green Net Plan" carbon neutrality target: "GAC Group promises to achieve carbon neutrality of the whole life cycle of its products by 2050 (challenge 2045). ”
In response to the "Green Net Plan", GAC Trumpchi released the development strategy of "hybridization + intelligence" dual-core drive, with the goal of achieving hybridization of all models in 2025, with hybrid sales accounting for more than 60% in 2030, challenging to achieve carbon neutrality in 2045.
In addition to accelerating the launch of hybrid models, GAC Trumpchi will also focus on building carbon neutral factories, introducing green electricity and super photovoltaic power generation systems, aiming at zero carbon, and realizing the digitization, intelligence and low carbonization of the whole industry chain.
GAC Trumpchi aims to build the strongest hybrid technology platform in China based on GAC Julang Power. Through open cooperation and independent research and development, GAC Trumpchi has two sets of industry-leading hybrid systems.
A set of GAC 2.0ATK engine and GAC GMC2.0 hybrid system is combined, the engine has a maximum thermal efficiency of 42.1%, and a thermal efficiency utilization rate of up to 95.5%. GAC has independently developed GMC electromechanical coupling hybrid system, which is compatible with hybrid and plug-in hybrids, and GAC has complete independent intellectual property rights.
One is GAC's third-generation 2.0TM engine and Toyota's fourth-generation THS hybrid system. The new second-generation GS8, which was the first to carry this system, locked in the explosive model as soon as it was unveiled, and the order went all the way up after the listing.
"There are only two hybrids in the world, one is the Toyota hybrid and the other is the other." People often use this phrase to praise Toyota hybrid technology.
Toyota THS Hybrid System has more than 20 years of technical accumulation, after four iterations, deeply rooted in the essence of hybrid technology. It is a generator, drive motor, planetary gear mechanism, P-gear parking mechanism, mechanical pump, etc. highly integrated in one, the whole system structure is simple, small size, light weight, power control unit power density and efficiency is higher than the same type of products.
With the blessing of multiple technologies, the THS system can reasonably control the distribution of fuel power and electric power, so that the power system always runs in the efficient range, and realizes both fuel consumption and power.
Vehicles equipped with Toyota's THS system have sold more than 18 million vehicles worldwide, and their total battery is equivalent to about 260,000 pure electric vehicles, but the CO2 emission reduction effect is equivalent to about 5.5 million pure electric vehicles.
On the one hand, GAC independently developed a hybrid system with GMC as the core, and on the other hand, through a strong alliance with Toyota, GAC Trumpchi became the first Chinese brand equipped with Toyota's hybrid system THS. With the support of two sets of hybrid systems, GAC is building the strongest hybrid platform for Chinese brands.
