On January 8, 2021, the Ministry of Industry and Information Technology, member of the Ministry of Industry and Information Technology, Host Xin Guobin, presided over to convene electric vehicles, emphasized that electric vehicles low-temperature use problems related to consumers, should be "people The fundamental departure point of the center, high attention, carefully solved; vehicle and battery companies should strengthen technical research, improve the low temperature driving performance of electric vehicles, improve user experience, universities and research institutions to strengthen basic commonal technology research, and have strong support for industrial development. Positive cold winter, many regions in my country ushered in strong cooling weather. Recently, the major media has also reported that "cold wave strikes, new energy owners in Tricky shit" and other winter lithium-ion batteries.

Winter new energy cars are powered down, how is it difficult to charge? New energy vehicle promotes bottleneck how to break? Become an issue that needs to be solved in the industry. Winter lithium-ion battery power-down phenomenon has found that there is a way to understand that in low temperature, the lithium ion activity in the dynamic lithium ion battery is lowered, and even some lithium ions lose activity, which is also a lot of new energy vehicles charge. Reasons why you do not advance, and the cause of slow charging.

At the same time, the electrolytic solution of the power lithium-ion battery has become more viscous due to the low temperature environment, and the energy consumption of the lithium ions during the discharge process, leading to the vehicle "running". In response to the battery's "non-tolerance" of the battery, many companies have studied various types of battery thermal management systems, I hope to keep the dynamic lithium-ion battery to solve the "afraid" problem. Battery thermal management system accurately measures and monitors battery temperature, heat dissipation during battery pack temperature, fast heating under low temperature conditions.

However, there are currently in the starting stage, and there are differences in technology, cost, scale, supporting, and prices of technology, cost, scale, supporting, and prices in the entire industry. In the northern region, the thermal management system has higher cost and system complexity requirements. Some time ago, Harbin was fired in the open air banking process of a brand pure electric passenger car.

The fire rescue brigade "Fire Accident Certificate" recognizes: the vehicle is abnormal during the charging process, the power lithium-ion battery heating system is abnormal, and the temperature in the battery pack continues to rise, resulting in fire burning. For winter lithium-ion batteries, the R & D battery thermal management system is a feasible method, but whether the effect or safety risks are expected, but also need to further verify. Yinlong titanate can be highly low-temperature effective to solve new energy vehicles winter operational challenges, is there a power lithium-ion battery with low temperature resistance? The answer is.

According to CCTV Financial Channel: lithium silver titanate has good low temperature, the lowest temperature in the simulation experiment is -50 ° C. The lithium titanate structure is stably, with a three-dimensional lithium ion diffusion passage and the surface does not form a solid-liquid interface passivation film, and the kinetic performance can still maintain a normal temperature at low temperatures. Charging does not cause a short circuit or a lithium branch crystal that causes negatively deteriorated, with the ability to completely charge and discharge at a super wide temperature range of -50 ° C ~ 60 ° C.

Regarding the unique environmental factors in the northern cities in the winter, the new energy vehicle needs to be "pressed the disease", "low temperature" is the primary choice. Yinlong's new energy has been dedicated to the development of lithium titanate, and the lithium titanate-based lithium-ion battery has a wide range of temperature, high safety, long life, fast charge and other characteristics, still maintains stable operation in a cold environment. Effectively solve problems in the operation of new energy vehicles.

At the same time, Yinlong New Energy Car operates in the cold area of ​​Harbin, Hohhot, Baotou, etc. Technology is progressing, the era is more in the past, and the new energy vehicle is still a general trend. I believe in the near future, in the practice and application of the lithium-cell-based lithium-ion battery solution for Yinlong New Energy, the new energy vehicle will break through the chains of cold winter, usher in warm spring.
