From the perspective of technical reserves, the mass production of 800V high-voltage platforms also means that China's new energy automobile industry has officially entered the era of super fast charging.
At four o'clock in the morning, Los Angeles has teenagers chasing basketball dreams, and at four o'clock in the morning, there are online ride-hailing drivers queuing up to recharge their lives.
"It takes nearly 2 hours to charge one charge, and twice a day." It is the current bottleneck of new energy vehicle charging technology that gives online ride-hailing drivers a life problem. According to CCTV financial reports, in order to get out of the car smoothly in the winter, drivers can only be forced to get up early to seize a few fast-charging piles, and even so, they often can't grab it.
With the unexpected development of the new energy market in 2021, the industrial pain points of "slow charging and difficult charging" have rapidly upgraded, making online car drivers miserable, and greatly affecting the car experience of the majority of new energy car owners, and the entire new energy industry is eager for more efficient and convenient charging methods.
According to the research of Lingying Consulting, in view of the actual needs of domestic users for fast charging and mileage, among the many solutions, the high-voltage vehicle system (800V platform) and the supporting super charging pile are currently favored by most automakers, coupled with a new power battery technology with a high charging rate, at that time, the application side of the "charging and mileage anxiety" is expected to be significantly alleviated.
At the same time, Ouyang Minggao, an academician of the Chinese Academy of Sciences, also pointed out at the seminar organized by the Electric Vehicle Hundred Association that to solve the worries of charging, greater power fast charging technology is needed, super fast charging is the trend of the times, and the industry needs to promote the use of higher voltage platforms of ≥800V for electric vehicles. It can be seen that the 800V high-voltage platform has been recognized in the industry and can effectively solve the technical development route of charging problems.
At present, the domestic hot-selling model voltage platform is still generally stuck between 400-600V, such as Tesla Model 3 voltage platform is 400V, with its self-built supercharge pile can be charged for 15 minutes to travel 279km, the theoretical charging rate is about 1.85C, which is the industry's higher level; BYD Han EV cruising range of 550km, the maximum charging system voltage is 569.6V, can achieve 25 minutes 30%-80% SOC charging speed.
However, if the new energy vehicle can be equipped with an 800V voltage platform, the charging rate can easily achieve 2.2C-4C, and the charging speed is greatly improved. At that time, the new energy vehicle supplementary energy can basically be comparable to fuel vehicles, and the historical problem of "slow charging and difficult charging" of new energy will also be solved.
In the field of complete vehicles, Porsche Taycan has taken the lead in bringing the 800V voltage platform into the mass production of electric vehicle models, and in the field of power batteries, there are also forward-looking companies that have laid out the 800V high-voltage platform early. Among them, such as Fu Neng Technology's 800VTC overcharge and overpressure technology, it has become the industry's first 800V high-voltage platform that can achieve mass production so far.
From the perspective of technical reserves, the mass production of 800V high-voltage platforms also means that China's new energy automobile industry has officially entered the era of super fast charging. After coordinating with the whole vehicle and the national power network, the mileage anxiety will be completely eliminated from the dictionary of new energy.
800V high-voltage fast charging has become a mileage anxiety "game breaker"
Since Porsche Taycan first brought the 800V voltage platform into the mass production of electric models, in 2021, domestic and foreign car companies set off a wave of 800V voltage platform model releases in an attempt to seize the new highland of high-power fast charging. Obviously, 800V high-voltage fast charging is already recognized in the industry as a mileage anxiety "game breaker".
According to the formula of electrical power, P = IU, to increase the charging power, either increase the voltage or increase the current. However, due to the high current for the charging gun, cable and battery core components will produce a high heat loss, the theoretical increase limit is not high, the current mainstream charging gun maximum current limit of 500A, can achieve the charging power of about 200kW, but also far from meeting the charging needs.
In contrast, the technical route of increasing the voltage can not only easily achieve a rapid increase in charging rate, but also reduce heat loss, reduce the quality of the whole vehicle, optimize the power structure, improve safety performance, and so on.
As far as the current hot selling part of the pure electric models are concerned, the average charging rate of the matching power battery DC fast charging theory is about 1C, and it takes at least 30 minutes to complete the 30%-80% SOC, considering the impact of charging efficiency and temperature, 0~100% SOC is basically more than 90 minutes. Once a long-distance trip is required, such a charging efficiency is unacceptable to the user.
The existing 800VTC overcharge and overvoltage platform technology of Fu Neng Technology can make the charging rate reach 2.7C, and the package charging equivalent is 2.2C. This means that SOC's 10%-80% charge takes only 15 minutes, which is much higher than the current charging speed, which is at an industry-leading level; its next-generation product technology can shorten this process to 7 minutes, so that electric vehicles can compete with fuel vehicles in terms of power replenishment. That is to say, with this set of technology, the time spent charging electric vehicles will be greatly compressed, and only the time to take a short break in the service area for a meal can be charged to 80%, and even more worry-free than refueling.
More importantly, after the new energy vehicle is equipped with the 800VTC overcharge and overvoltage platform technology of Fu Neng Technology, it can also increase the cruising range by 5% on the basis of the original voltage platform. At the same time, high voltage brings high power, and low heat production, while significantly improving battery safety, it can help the acceleration performance of the whole vehicle to easily cross the threshold of 3 seconds to break through the hundred, completely crushing ordinary fuel vehicles, bringing extraordinary driving pleasure.
Obviously, the 800V voltage platform for the new energy vehicle to bring a fast charging time, safety, endurance, power performance and other aspects of the improvement, is the automotive voltage platform from the initial 6V battery gradually improved, the quantity of the change to the qualitative change of the key node.
But the current industry consensus is that the 800V high-voltage charging system cannot be achieved overnight, which means that during the transition period, the 400V-800V system will be a coexistence state, and a qualified high-voltage electric vehicle must be compatible with high and low voltage platforms.
As a producer of products, Fu Neng Technology has fully realized the short-term shortcomings brought about by technological progress. Its 800VTC overcharge and overvoltage platform automatically identifies the voltage platform of the pile through the intelligent switch matrix inside the BDU, realizing the automatic switching of 800V and 400V, which is compatible with the domestic 800V/400V charging pile, and also greatly facilitates the user's choice.
Because of this, Fu Neng Technology, which has been quietly cultivating the industry for many years, won the Prospective Powertrain Excellence Award in the 6th Lingxuan Awards with its 800VTC supercharge and overpressure technology, and won the Annual Innovative Technology Award in the golden globe award of high-tech lithium battery.
The logic behind Fu Neng Technology's frequent awards is that on the eve of the imperative of high-power fast charging of new energy vehicles, a mature, mass-producable 800V high-voltage platform is of great significance. As a supercharging platform technology with a charging rate of 2.2C-4C, Fu Neng Technology's 800VTC overcharge and overpressure technology has made a correct demonstration for the industry to solve the user's energy replenishment anxiety.
High-power fast charging reshapes the pattern of new energy vehicle power replenishment
Under the leadership of Fu Neng Technology's 800V high-voltage platform technology, the entire industry is accelerating its leap to 800V high-voltage platform in an attempt to seize a new high ground of high-power fast charging.
Internationally, Hyundai, GM, Volkswagen, Mercedes-Benz and other mainstream car companies have announced 800V high-voltage platform plans; and in China, including Lantu, Geely Kr, Xiaopeng, GAC E-An, BYD e platform, ideal and other car companies have also accelerated the layout of 800V fast charging technology.
According to Anxin Securities forecast, in 2021, the domestic mass production of high-voltage platform models include Extreme Kr 001, BYD Han EV, BAIC Jihu Alpha S Hi Edition, etc., the annual sales volume is expected to be about 70,000 units; in 2025, 5 million new energy vehicles are expected, of which 3 million will be equipped with high-voltage platforms.
In terms of segmentation, Essence Securities expects that from 2021 to 2025, the sales volume of domestic high-voltage platform models will be about 7, 31, 73, 148 and 3 million units, respectively. From 2022 to 2025, the year-on-year growth rate of high-voltage platform vehicles will be 335.4%, 137.7%, 101.8%, and 102.3%, respectively.
It is foreseeable that in the next few years, the sales of models equipped with high-voltage platforms will increase exponentially. This also means that the 800V high-voltage platform has become the standard for new energy vehicles.
At the same time, the number of high-voltage high-power charging piles adapted to 800V high-voltage models will also increase. In 2021, the industry is expected to lay 3,000+ ultra-fast charging piles, and the number will be expanded to 10,000+ by 2023. Coupled with the upgrading of existing piles, there will be more powerful charging piles at the end of the road in the future.
Under the synergy of high-pressure fast charging technology-market-supporting, it is not difficult to speculate that mileage anxiety will withdraw from the historical stage of new energy at a speed visible to the naked eye. When charging no longer becomes a trouble, the "crowded" new energy vehicle power supply pattern will change, returning to the convenient, comfortable and green nature of new energy vehicles.
In the epoch-making process of new energy vehicles returning to the essence of sustainable development, Fu Neng Technology, which grasps the "bull nose" of core technological innovation and takes the lead in mass production of 800V high-voltage platform, is indispensable. At the same time, the application and promotion of fast-charging batteries will certainly trigger revolutionary changes in electric vehicles and many application scenarios.
The popularity of super fast charging makes electric vehicles become mobile energy storage devices in the true sense, through V2G technology, so that electric vehicles can be charged when the power grid load is low, discharged at the peak of the power grid load, dig deep into the energy storage value of power batteries, optimize the energy structure, and improve energy efficiency.
At the same time, super fast charging also provides a solid theoretical foundation for the landing of the concept of flying cars. At present, the biggest obstacle to flying cars is the battery, which needs to lift the battery pack into the air, which means that only high-energy density fast-charging batteries can make flying cars a reality. At that time, urban traffic will change from flat to three-dimensional, which is expected to completely solve the traffic congestion problem caused by urbanization.
It is reported that the 800V overcharge and overpressure platform that the R&D team of Fu Neng Technology has overcome for 3 years has been technically docked with a number of automobile brands, and the technology will also cover application fields such as flying cars in the future, providing a full set of services for completely solving the mileage anxiety of new energy travel.
Behind this is fu neng technology's low-key deepening of battery technology for more than 20 years. At present, Fu Neng Technology has a global R & D team of more than 1,000 people, has mastered dozens of independent research and development of the core technology of the whole industry chain, and obtained and is applying for more than 200 domestic and foreign patents. At the same time, Fu Neng Technology is well aware of the importance of core technology innovation, and the amount of R&D investment in 2020 exceeded 370 million yuan, accounting for 33.21%.
Innovative technology empowerment, leading the development of the new energy era
There is no doubt that the 800V high-voltage platform can effectively solve the important direction of the development of new energy vehicles, but it is often the whole body that is involved, and the high-voltage platform seems to only increase the voltage from 400V to 800V, but behind it is the upgrading of the entire system.
Once the new energy vehicle is to be fully replaced by a high-voltage platform, the upstream and downstream of the entire industry will create a new demand gap, and most of the original components need to be redeveloped and designed to match the high-voltage platform. At the same time, large-rate fast charging is easy to produce lithium evolution, and once the charging rate reaches more than 4C, it will greatly affect the stability of the battery, which poses a great challenge to the existing battery technology, especially the BMS technology.
Among them, the most typical is that due to the material limit, the silicon-based IGBT chip, which was originally in full swing in the new energy automobile industry, was replaced by silicon carbide with the advantages of high pressure resistance, high temperature resistance and high frequency. SiC power devices not only meet the needs of 800V voltage platforms at both withstand voltage and loss levels, but also have the potential to be further expanded to 1200V voltage platforms. According to Anxin Securities, the market size of domestic new energy vehicle silicon carbide power devices is expected to reach 6 billion yuan in 2025.
The complexity of the linkage upgrade of downstream vehicles, piles and charging networks is also far beyond imagination. An indisputable fact is that the current grid conditions can not support the construction of intensive supercharger piles in the short term, how to rationally distribute, the maximum use of limited resources to meet the travel needs of car owners, including complex big data calculations, as well as intelligent technologies such as "planning driver itinerary".
Mileage anxiety brings the demand for high-voltage charging platforms, and high-voltage charging platforms create new demands upstream and downstream, thus transforming and upgrading the entire industry, an industry is often in the repeated pull of demand and technology spiral upwards.
As Dr. Wang Yu, Chairman of Fu Neng Technology, said at the 2021 Annual Meeting of Gaogong Lithium Battery: "The new era of green development has given the lithium battery industry a new mission to drive carbon neutrality, leading the industry to a new journey of product innovation and co-creation, win-win industrial chain collaboration, and sustainable development and common prosperity." "The global energy Internet will also be a systemic solution platform for developing a low-carbon economy and realizing energy transformation and transformation." In the great leap forward of 800V high voltage fast charging, Fu Neng Technology's 800V high voltage platform has taken a crucial first step for the industry.
At present, Fu Neng Technology is connecting with a number of large vehicle companies at home and abroad for 800V high-voltage platform projects, applying the technology to newly developed cooperative models, and is committed to launching highly competitive products in the industry. With the continuous maturity of the upstream and downstream systems of 800V high-voltage fast charging, the expansion of production capacity of power battery enterprises has become a trend. In view of this, Fu Neng Technology's production bases in Ganzhou, Jiangxi and Zhenjiang, Jiangsu are all at full capacity, and in Wuhu, Anhui Province, the annual output of 24GWh battery projects, but also plans to establish new production bases in China, Europe and North America, improve the global layout, and serve global vehicle customers. It is estimated that in 2025, the power battery production capacity investment of Fu Neng Technology and the joint venture company will reach 120GWh, ensuring the demand for power batteries from customers around the world.
In the context of the approaching global carbon neutrality "big era", the deep integration of energy and transportation is accelerating, technological innovation will play an increasingly important role in this huge industrial change, and with 800VTC supercharge and overpressure technology as an important starting point, Fu Neng Technology has seized the opportunity in this sustainable development competition. In the next few years, Fu Neng Technology will also participate in this global competition as the head of China's new energy brand internationalization, thus creating unlimited possibilities in the new energy era.
