On October 18 this year, the "China International Energy Conservation and New Energy Vehicle Exhibition (IEEV)" jointly sponsored by the Beijing Municipal People's Government and the Ministry of Industry and Information Technology opened grandly at the Beijing National Convention Center. With the theme of "opening a new era of automobiles", the exhibition once again heated up the concepts of "new energy" and "energy saving", which attracted the attention of people in the automobile industry and consumers, and provided some emerging self-owned brand products and technologies. Great opportunity.
Among the many manufacturers that appeared in this exhibition, Lanuo New Energy won the "2018 Excellent Hybrid System Supplier" award issued by the organizer of the conference with the differentiated route selection of "48V light hybrid system + lithium titanate battery". Such a unique choice of technical route has given China and even the global auto industry a brand-new solution, and may it become the mainstream configuration of energy-saving cars tomorrow?
Founded in 2015, Shanghai Lannuo New Energy Technology Co., Ltd. is committed to fulfilling a golden promise with a national independent brand - to make the sky bluer and the water clearer. This is also the origin of the company name "Lannuo". It is not difficult to see from this that entrepreneurs are green and sustainable in terms of entrepreneurial ideas. This is also confirmed in the interview with the company. The founder Han Li said: "AZUR means azure in French, and EVE is taken from part of the letters of English Everywhere. The English name of Lannuo AZUREVE means a piece of azure everywhere. A symbol of hope. We hope that technological progress will save non-renewable energy as much as possible while meeting human needs, so as to achieve the goal of "sustainable development". This is the report of the 19th National Congress of the Communist Party of China. "A manifestation of an important spirit."
"The key to fulfilling the blue promise lies in our unique product line," said founder Han Li. Indeed, in the process of entering the market, Lannuo New Energy chose "product focus" and "differentiation strategy". Their technical route is unique in China. According to the founder: "What we do is not to promote It is not a product, but to promote a technical route and try to establish a standard system in a new application field.Titanic acid battery is most suitable for the application of hybrid electric vehicles, and can obtain lower fuel consumption and gas emissions through various control methods , so I believe - it is the mainstream configuration of tomorrow's energy-saving cars!"
48V light-hybrid technology, an opportunity for self-owned brands to comprehensively upgrade technology
In the context of global energy conservation and emission reduction, my country has introduced mandatory standards "Fuel Consumption Limits for Passenger Cars" (the fourth stage standard) and "Evaluation Methods and Indicators for Fuel Consumption of Passenger Cars", which clearly define the future development of passenger cars. Pointing to the word "fuel saving". my country's current main milestone goals are: by 2020, the average fuel consumption of new passenger cars is 5.0 liters per 100 kilometers; by 2025, the average fuel consumption of new passenger cars is 4.0 liters per 100 kilometers; liters/100km. Under high pressure, multiple technical schools are working together, some technical schools have emerged in the field of energy conservation, and a new generation of technology has begun to emerge.
In the field of hybrid electric vehicles, Japanese HEV technology has almost monopolized the market. In 2011, major European car companies jointly launched a 48V hybrid technology standard to compete with Japanese HEVs. Against such a background, the development of the 48V hybrid technology route of domestic self-owned brands has become a good way out, and some manufacturers (such as today's protagonist-Lano New Energy) have gradually surfaced, and continue to accept OEMs verification.Also read:https://www.aimeno.com/lithium-battery-pack/196.html
First of all, from the perspective of cost-the price/performance ratio is gratifying. At present, my country's 48V hybrid technology only needs 30% of the manufacturing cost of the high-voltage hybrid system, but can achieve 70% of the fuel-saving effect of the high-voltage hybrid system; in addition, OEMs can continue to use the original powertrain structure and gradually increase The complexity of its hybrid motion optimizes fuel consumption and emissions. The 48v power system consists of a small engine and an electric motor. The battery is used to store the energy recovered during the start/stop/brake process. It requires little modification to the vehicle and a low production line modification cost. It is more suitable for the transformation and upgrading of traditional car companies at home and abroad.
Secondly, according to IHS "Global Insights", by 2025, the market share of 48V hybrid vehicles will account for 95% of the global light hybrid market, which will be almost half of the total global hybrid vehicles. And its latest forecast also shows that by 2025, the global annual output of 48V vehicles will reach 13.6 million. More importantly, China will become the main market for 48V technology in the future. By 2025, nearly 8 million 48V models will be produced in China. In the future, it may really become the most effective solution for energy-saving vehicles!
Ternary positive lithium titanate negative battery is the best safe and reliable hybrid battery solution
Since the industrialization of lithium-ion batteries in 1991, the negative electrode material of batteries has been dominated by graphite. In recent years, lithium titanate has been valued as an anode material due to its many excellent properties.
First, lithium titanate batteries can be used safely in both high-temperature and low-temperature environments, and it also reflects its important advantage of wide temperature resistance (especially low temperature resistance). Generally, electric vehicles will have problems charging and discharging at -10°C. Lithium titanate batteries can be charged and discharged at -40°C to +60°C, whether in the frozen northern Europe, northeast China, or in the hot Southeast Asia, the equator The vehicle will not affect the work due to battery "shock", which eliminates the worries of users and OEMs.
Second, compared with safety issues such as accidents caused by short-circuit fire caused by crystal precipitation on graphite negative electrodes, lithium titanate negative electrodes have no concerns in this regard at all. Once the traditional graphite negative electrode is overcharged after lithium intercalation, metal lithium is easy to precipitate on the surface of the electrode. After the diaphragm is pierced, it will react with the electrolyte to produce flammable gas, which brings great safety hazards. In comparison, the negative electrode potential of lithium titanate is higher than that of pure metal lithium, and it is not easy to produce lithium crystals, which greatly improves the safety performance of lithium batteries. A third-party organization once tested lithium titanate batteries and found that under harsh tests such as acupuncture, extrusion, and short circuit, it can achieve no smoke, no fire, no explosion, and its safety is much higher than other lithium batteries.
Third, the crystal structure of the lithium titanate material can maintain a high degree of stability during the intercalation and deintercalation of lithium ions, and the lattice constant changes little. This "zero strain" electrode material greatly prolongs the cycle life of lithium titanate batteries. The average cycle life of ordinary batteries is 3,000 times, while the number of full charge and discharge cycles of lithium titanate batteries can reach more than 20,000 times. After being used as a power battery for 10 years, it may be used as an energy storage battery for another 10 years. From the perspective of the whole life cycle, the cost of lithium titanate battery is lower.
Fourth, another advantage of lithium titanate is strong fast charge and discharge capability and high charge rate. Compared with graphite anode materials, lithium titanate has a higher lithium ion diffusion coefficient and can be charged and discharged at a high rate. At present, the charging rate of the high-power lithium titanate battery selected by Lannuo can reach more than 50C, while the battery charging rate of ordinary graphite anode materials is generally only 20C. While greatly shortening the charging time, the cycle life is less affected and the thermal stability is also stronger.Also read:https://www.aminobattery.com/product/
To sum up, lithium titanate batteries with wide temperature resistance, safety, long life and fast charging have irresistible competitive advantages.
Shanghai Lannuo New Energy, thanks to the founder's ten-year vision and experience in the field of new energy batteries, keenly seized the opportunity, perfectly combined 48V hybrid technology with lithium titanate batteries, and conducted in-depth research on The coordination and control of each part of the 48V power system adopts the unique on-board intelligent fast charging technology, and makes full use of the advantages of lithium titanate battery charging and discharging times to achieve the best fuel saving rate. The battery system is really developed from the height of the vehicle demand, and it directly points out various challenges such as the unsatisfactory fuel consumption of the hybrid vehicle products in the current market, the low system efficiency and the need to improve the driving experience, which is eye-catching!
At present, based on the strategic positioning of leading international technology, the company has carried out technical cooperation and development with many well-known domestic and foreign OEMs. The high-power 48V battery system, HEV battery system, PHEV battery system, HCU, BMS and other products of the light-hybrid system vehicles mainly promoted by the company have entered the product testing and verification stage, and have achieved good results. In addition, high-power 48V systems can also be quickly upgraded to high-voltage HEV systems. At present, in order to improve product price competitiveness, Lano New Energy has designed and developed a platform for sharing modules between 48V and high-voltage HEV systems, which can further significantly reduce production costs. At present, many manufacturers have clearly expressed their willingness to cooperate, and are now fully entering the mass production preparation stage.
Lannuo, an auto parts company with its own brand, has the courage to face opportunities and challenges in the field of automobile electrification, which is a battle for hegemony. Under the circumstance that the sad situation of "hollowing" of traditional automobiles is difficult to reverse, private brand parts companies devote themselves to research and development, boldly innovate, and have ambitions to change this situation in the field of energy-saving and new energy vehicles, and strive to catch up with internationally renowned brands. Parts companies, exciting! Cao Nanhai, head of product development technology of Lannuo, said: "Engineers rely on data to speak. I think the hybrid battery products independently developed by Lannuo are not inferior to similar international products in terms of indicators and parameters, and even have more obvious performance in some aspects. Advantages. Lano's hybrid battery is one of the core components of vehicle electrification, and we will continue to ensure product quality.
