If the automobile industry is compared to an aircraft carrier sailing on a new channel, the underlying technology is like an engine, providing surging power for advancement; industrial integration is like a compass, pointing out the direction for transformation. What are the underlying key technologies in accelerating the electrification transformation of the automobile industry? In the face of bottlenecks in the development of industries such as charging and battery life, what new ideas will the integration of green energy and transportation bring to China's auto industry?
Recently, Hou Jinlong, President of Huawei Digital Energy Technology Co., Ltd., expressed his views at the China Electric Vehicle Hundreds Forum (2023) that attracted industry attention.
Hou Jinlong, President of Huawei Digital Energy Technology Co., Ltd.
Hou Jinlong said, " In the field of transportation electrification, Huawei Digital Energy is positioned as a power domain solution provider and a charging network solution provider. Through the high-quality coordinated development of smart electric and charging networks, user experience will be improved and electrification will be accelerated. process. "
Transportation and energy, the historic integration of two industries
In human history, every integration and development at the industrial level will bring about a huge improvement in social and economic efficiency and a leap in the quality of people's life experience. The accelerated integration of the two major industries of transportation and green energy is driving the automotive industry to accelerate the transformation of electrification that has not happened in a century.
The two major industries of transportation and green energy have never been more closely linked than they are today. On the one hand, the transformation of the energy industry is inseparable from transportation: transportation is one of the most important energy application scenarios. According to statistics from the International Energy Agency, carbon emissions in the transportation sector account for 23% of the total global carbon emissions, more than one-fifth. Hou Jinlong believes that carbon neutrality has become the common mission and the most urgent need of all mankind, and the electrification of the transportation industry will be the key path for global carbon neutrality.
On the other hand, the upgrading of the transportation industry is also inseparable from the promotion of energy: the further improvement of the penetration rate of new energy vehicles, the improvement of the utilization rate of renewable energy in the transportation industry, the improvement of energy efficiency, the construction of new urban infrastructure such as charging networks, They are all inseparable from the support of a large number of new energy technologies that continue to innovate.
The integration of green energy and transportation electrification is the only way to accelerate the transformation of the automobile industry and promote the leap from the era of traditional automobiles driven by fossil energy to the era of intelligent networked electric vehicles.
Low-carbonization and digitalization are the two directions to accelerate the transformation of the automobile industry
Hou Jinlong believes that low-carbonization and digitization are two definite trends in the 21st century, and they are also two directions to accelerate the electrification transformation of the automobile industry.
In terms of low-carbonization, the transportation industry will accelerate its evolution towards green and low-carbon on both the power generation side and the energy consumption side. On the power generation side, the proportion of global renewable energy power generation will increase from the current 25% to 90% in 2050, and the energy demand of the transportation industry in the future will be dominated by clean energy. On the energy side, the electrification transformation of the transportation industry is the general trend, and the global penetration rate of new energy vehicles will increase from the current 2.5% to 70% by 2050. At that time, the huge global new energy vehicle market will become the core application scenario of newly added renewable energy power generation (green power).
In terms of digitalization, Hou Jinlong believes that "through the integration of 4T technology, namely: digital technology Bit, power electronics technology Watt, thermal management technology Heat, and energy storage management technology Battery, the automotive industry will accelerate the transformation of electrification and intelligence." On the one hand, electrification will realize a new energy power transformation that integrates power batteries, power electronics technology and digital control technology. On the other hand, intelligence is based on electrification, and deeply integrates digital technologies such as connection, sensing, cloud, and AI to realize the transformation of smart travel experience.
Low-carbonization and digitalization represent the latest developments in new energy technology and information technology. When the two technologies are integrated and implemented in the transportation industry, cars will gradually become the third space besides homes and offices. A low-carbon smart The era of connected electric vehicles has arrived.
Two-wheel drive: Coordinated development of smart electric vehicles and charging networks
In the process of vehicle electrification, inconvenient charging, anxiety about battery life and low cost performance are the three main problems currently affecting users' choice of new energy vehicles, which directly affect the further improvement of the penetration rate of new energy vehicles. For example, battery life anxiety in scenarios such as high speed and low temperature in winter makes many users discouraged from new energy vehicles. With the reduction of subsidy policies, the prices of new energy vehicles, especially A-class vehicles, are still high. For car companies, new car development costs are high and the cycle is long, leading to cost performance bottlenecks for new energy vehicles.
In view of the above industry bottlenecks, how to integrate digital technology and power electronics technology to realize the coordinated development of smart electric vehicles and charging networks is the direction for the industry to break through.
- R & D cost reduction and efficiency increase, improve the cost performance of the vehicle
In recent years, the research and development cycle of new energy vehicles has dropped from three to four years in the period of fuel vehicles to within two years. Even so, the high R&D cost and long cycle time of car companies are still the primary factors affecting the cost performance of complete vehicles, especially for A-class cars that occupy the main force in the market.
In order to help car companies build better cars faster and more efficiently, Huawei Digital Energy launched the world's first hyper-converged 7-in-1 electric drive system, which uses advanced technologies such as power & algorithm fusion, which can save car companies 10 million in development costs and shorten The development cycle is 2 months. This makes it possible for car companies to create "the price of A-class cars, the space and power experience of B-class cars".
- Relieve battery life anxiety
How to "make more mileage per kWh" is the ultimate expectation of users for the battery life of new energy vehicles. Huawei Digital Energy has built the industry's highest-efficiency electric drive system for mass production. Through high-efficiency SiC modules, ultra-high-speed flat-wire motors, and intelligent oil cooling design, it achieves three-level efficiency from components to systems to complete vehicles, with an efficiency of up to 92%. Under the same battery configuration, the cruising range of the vehicle is increased by 4.5%. For hybrid vehicles, Huawei Digital Energy has launched the industry's first range-extending 2-in-1 electronic control system, which can bring users lower fuel consumption and a quieter driving experience.
- Faster and more convenient charging experience
In the future, the charging experience of new energy vehicles should be "charging wherever there is a road". Huawei Digital Energy maintains a technological leadership in high-power ultra-fast charging and super-charging system architecture. At the Shanghai Auto Show in April this year, Huawei Digital Energy will bring the second-generation high-voltage platform power domain solution to achieve 200 kilometers of energy replenishment in 5 minutes; at the same time, it will also release the world's first fully liquid-cooled, optical-storage integrated overcharging system architecture, Accelerate the high-quality development of charging infrastructure.
The integrated development of the two major industries of transportation and green energy has provided a historic opportunity for my country's auto industry. In the field of power domain, as a component supplier, it is committed to helping car companies build good cars and bringing the best driving experience to users. Huawei Digital Energy looks forward to working with customers and partners to open up cooperation, contribute to the electrification of transportation and the goal of "carbon neutrality", and build a green and beautiful future.
