Through a series of innovative achievements such as C2B technology, Kirin battery and Shenxing battery, as well as new materials for single crystal nickel-cobalt-manganese cathode, we have set a world record of 240 mA-hour per gram.
Q:How does Ningde era provide adaptive battery solutions for different vehicle scenarios?
A:The goal of our Ningde era is to make every technical route to the extreme and put it in the most suitable scene. For example, the fully upgraded third-generation Shenxing super-rechargeable battery has the strongest control capability, can achieve fast charging in extremely cold environments, and ensure safe charging throughout the life cycle. In addition, the latest products of Kirin, Xiaoyao and other brands will also come standard with this charging capability.
Q:How does ohmic impedance affect battery performance, and why did Ningde era choose 300mm batteries as its standard size for ultra-high speed batteries?
A:Ohmic impedance is a parameter that measures the resistance of a conductor to current. Its size is proportional to the length of the conductor and inversely proportional to the cross-sectional area. Therefore, the longer the conductor, the greater the ohmic resistance, which in turn affects the heat generation and overall performance of the battery. After precise calculation in Ningde era, it is found that the 300mm battery core can reduce the heat production by more than 20% compared with the 400mm battery core. Based on this scientific judgment and long-term persistence, Ningde era has chosen 300mm batteries as the standard size for ultra-high speed batteries since 2015.
Q:How to solve the problem of interface reaction impedance through technological innovation in Ningde era?
A:Interfacial reaction impedance refers to the resistance encountered when lithium ions pass through the SEI film with a thickness of more than ten nanometers on the surface of the negative electrode of the cell. In order to solve this problem, Ningde Times Industry pioneered SEI gene directional editing technology. By accurately locating and replacing the substance X that hinders the migration of lithium ions, it is replaced by imitation biomass KE, thus greatly improving the ability of lithium ions to pass through SEI membrane and achieving the effect of both overcharge speed and battery life.
Q:How does diffusion impedance affect battery performance, and how did the Ningde era deal with this problem?
A:Diffusion resistance is the resistance encountered in the process of lithium ion intercalation into the negative graphite layer, because the graphite layer spacing is very narrow and the repulsive force between atoms will affect the lithium ion intercalation rate. In this regard, Ningde era adopted a new supporting graphite technology to transform the single atomic layer graphite, similar to implanting stents in narrow capillaries, effectively broadening the width of graphite layers and significantly improving the intercalation speed of lithium ions.

Q:How to solve the problem of internal temperature measurement of battery pack in Ningde era?
A:Based on the electrochemical thermal coupling physical model combined with NTC real-time data, Ningde era accurately analyzes the real temperature inside the battery, controls the temperature acquisition accuracy within the range of plus or minus one degree, and successfully realizes the battery capacity retention rate after 1000 cycles of overcharge.
Q:In the cold environment, Ningde era how to achieve efficient battery overcharge?
A:Faced with the problem of reduced charging efficiency caused by the sharp increase of battery internal resistance in low temperature environment, Ningde era has proposed two solutions: one is the battery self-heating scheme, which allows the battery to heat itself up through oscillating current of a specific frequency without relying on external charging piles; The second is an integrated over-charging solution, which, combined with efficient power exchange service, can achieve 9-minute full charge in an environment of minus 30 degrees and take into account the demand for fast energy supplement.
Q:How does the Ningde era view the practice of lithium iron phosphate batteries in achieving a thousand-kilometer endurance and their contribution to the lightweight of automobiles?
A:Ningde Times believes that simply increasing the size and weight of the battery in pursuit of lithium iron phosphate to achieve a thousand-kilometer endurance is not ideal, which will seriously affect vehicle performance and handling, and is contrary to the automotive industry's pursuit of lightweight concept. Through the research and development of Kirin batteries and other products, Ningde era has realized that while maintaining high energy density, the weight of the battery pack should not exceed 750kg, so as to ensure the performance, safety and handling of the whole vehicle, and avoid the waste of resources and the negative impact on the user's driving experience.
Q:What is the impact of the vehicle weight loss of 255kg on the braking distance?
A:After losing 255 kilograms of weight, the car's 100-kilometer braking distance can be shortened by 1.44 meters. This gap may mean the difference between life and death under harsh conditions such as rain, snow, slippery or icy roads.
Q:What is the performance of lightweight for the improvement of vehicle durability?
A:The lightweight battery can reduce the wear of chassis tires, thereby increasing the service life of parts. For example, after weight loss, the service life of vehicle braking systems and suspension systems can be increased by 40%, tire life can be extended by more than 30%, and under certain conditions, the original tire replacement cycle of 3-40000 kilometers can be extended to at least 40000 kilometers.
Q:How does weight reduction improve vehicle energy consumption and carbon emissions?
A:Compared with lithium iron phosphate batteries with the same amount of electricity, a weight loss of 255kg can reduce the energy consumption of the whole vehicle by at least 6% for 100 kilometers. According to the calculation of 20000 kilometers per year, 1 million vehicles equipped with Kirin batteries can save 1.15 0.6 billion kilowatt-hours of electricity and reduce carbon emissions by about 78500 tons, which is equivalent to 1250 hectares of green space covered by 2.5 million trees.

In addition, for users who pursue higher endurance and want to control budget and weight, a super-hybrid system has been introduced. Through perfect integration of ternary and lithium iron materials, the energy density is increased to 230 watt-hours per kilogram, so that the battery pack can maintain its original weight, increase its endurance by 15% to 20%, and even achieve pure electric endurance exceeding 600 kilometers, redefining the endurance benchmark of pinhole models.
Q:Why set 600km as the new benchmark for pinhole tracks?
A:Because the 600-kilometer endurance not only realizes the quantitative change in the endurance, but more importantly, it brings a qualitative change in the user experience. When the pure electric endurance is less than 400 kilometers, the probability of turning on and using the range extender is as high as 15%, and when the endurance reaches 600 kilometers, according to the big data model derivation, the probability of using the range extender drops to less than 1%, daily commuting and long-distance travel almost do not need to start the range extender, and the comprehensive endurance can even exceed 2000 kilometers.
Q:What are the characteristics of the second generation super smart battery?
A:Xiaoyao's second-generation super intelligent battery can still stably output 1.2 MW of power under 20% SOC power loss state, and can generate more than 1.5 MW of instantaneous power under full power state, thus solving the pain point that battery power output is affected by power in hard-core off-road and ensuring strong and continuous power output in various harsh environments.
Q:How does Xiaoyao's second generation perform in off-road scenes?
A:In the face of complex off-road scenes such as chicken coop pits in the desert, Xiaoyao's second-generation battery pack can provide more than 350 kW instantaneous power and easily get out of trouble. Regardless of the power level, its power output remains strong. In addition, Xiaoyao's second generation ensures that the battery pack can remain safe and stable in extreme off-road environments through bulletproof bottom coating technology and the industry's top sealing and waterproof capabilities.
