Electrification technology of traditional automobile

Recently, auto stocks have suddenly skyrocketed, and many brands have daily limit. This reason is obviously because under the guidance of the Ministry of Industry and Information Technology on June 27th, 1000, the China Society of Automotive Engineering organized and issued the Technical Roadmap for Energy Saving and New Energy Vehicles 2.0, which was revised and compiled by more than one and a half experts in the whole industry. There should be no doubt that a road map will stimulate the stock market and the development of China's new energy automobile industry.

According to the plan, by 2035, the sales of energy-saving vehicles and new energy vehicles will each account for 50%, and the automobile industry will realize electrification transformation, and the number of fuel cells will reach about 6.5438+0 million; Traditional energy-powered passenger cars are all hybrid, and new energy vehicles have become the mainstream, accounting for more than 50% of sales. In terms of charging infrastructure, by 2035, slow charging piles (including free piles and public piles) will have more than 65.438+0.5 billion ports, and fast charging public piles (including special vehicles) will have more than 65.438+0.46 billion ports. This plan has set a hard goal, and major car companies will be in danger of life and death if they don't follow up in time. The intention of using this measure to rush to the forefront of the world's cars is also on the paper. In fact, even if it looks aggressive, it has a certain industrial base. In addition to the new forces, many car companies have also participated in the research and development of new energy vehicles, especially electric vehicles. Looking at the automobile industry, almost no automobile companies at home and abroad have not started the research and development of electric vehicles today.

Technology Roadmap 2.0 for Energy-saving and New Energy Vehicles covers nine key areas, including energy-saving vehicles, pure electric and plug-in hybrid vehicles, fuel cell vehicles, intelligent networked vehicles, power batteries, electric drive systems for new energy vehicles, charging infrastructure, automobile lightweight technology, intelligent manufacturing and key equipment. It can be seen that the technology roadmap provides technical guidance for the sustained, rapid and healthy development of China's automobile industry and promotes the accelerated development of the electric vehicle industry. Under the general trend of automobile new energy, all major automobile enterprises are facing strategic upgrading. How to choose a good opportunity for transformation, how to change and the pace of transformation all test the strategic decision-making and technical level of automobile enterprises.

China has drawn this road map for the automobile industry, so under the trend of new energy, who has been at the forefront of today's automobile industry? To say that new energy vehicles are brilliant now, Toyota is the only one. Only Toyota's current sales of new energy vehicles have reached more than 200 million, ranking first in the world. As another giant in the automobile industry, Volkswagen released a three-step strategy and product planning for energy conservation and environmental protection as early as 2009. Three years ago, it also announced a strategic plan to develop new energy vehicles in China. By 2025, Volkswagen will launch more than 20 new models, including imported and domestic plug-in hybrid vehicles and pure electric vehicles. By 2030, audi ag's direct investment in promoting the industrialization of electric vehicles will exceed 20 billion euros, which can be described as deep pockets. It is a gamble to develop new energy vehicles. In addition to traditional car companies, Tesla, the leader of pure electric vehicles, is not to mention. Recently, the Shanghai factory has invested a lot, and the price of the whole vehicle has gone down after being produced in China, which has brought a lot of pressure to all new energy vehicle developers. Automobile giants are fierce, domestic independent brands and joint venture brands have stepped up their follow-up, and domestic new energy brands have gradually emerged. It is better to catch up early than late, and the latecomers will catch up. In the industrial transformation to new energy, let's take a look at the development trend of some car companies.

Toyota

As early as 1997, Toyota launched the world's first mass-produced HEV model "Prius" based on the concept that "eco-cars can only contribute to the environment if they are popularized". Prius ". Today, the Prius has developed to the fourth generation.
