With the rapid development of electric vehicles, how to solve the safety problems brought by electric vehicles has become a new topic and difficulty in the automotive industry. As the power source (or one of the power sources) of electric vehicles, the power lithium battery system has become the focus of public attention for its safety and reliability. Studying the failure mode of the power lithium battery system is of great significance to improve the battery life, the safety and reliability of electric vehi

The direct consequence of the surge in investment is the "Great Leap Forward" in the production of power lithium batteries in 2016. The balance between the supply and demand of lithium-ion power lithium batteries will be broken, and the industry is facing a key turning point. In 2016, the production and sales of new energy vehicles in my country continued to increase rapidly. Electric vehicles from January to March [: Unless otherwise specified, the electric vehicles mentioned in this article include p

The performance of traditional anode materials has reached the limit, and the demand for anode materials in the traditional energy storage field has also been saturated, and the layout of the power lithium battery market has become a "must fight" for anode material companies. The four important components of lithium-ion batteries include positive electrode, negative electrode, electrolyte and separator. Among these four materials, the price of negative electrode material is relatively stable, and the t

On September 6, at the "Power Storage Battery Frontier Technology and Application" forum hosted by the Battery Industry Alliance, the reporter learned from Chen Chunmei, Director of the Automobile Division of the Equipment Industry Department of the Ministry of Industry and Information Technology that the Ministry of Industry and Information Technology is currently accelerating the drafting and compilation of "Promoting Automotive Power". The Guiding Opinions on the Development of the Lithium Ba

This paper introduces the characteristics of lithium-ion batteries, summarizes the development history of electric vehicle battery management systems, briefly introduces the requirements, functions, and technical characteristics of battery management systems, and makes an outlook for the development of electric vehicle battery management systems. The emergence of electric vehicles is driven by global warming, environmental pollution and energy crisis. In 2015, the global production and shipment of electric vehic

Unconsciously, the pace of 2016 has entered the ninth month, and the performance of the lithium battery industry in the first half of the year is obvious to all. The latest statistics from the National Bureau of Statistics show that from January to June 2016, the output of lithium-ion batteries was 2.976 billion, a year-on-year increase of 20.66%; the main business income was 114.436 billion yuan, a year-on-year increase of 26.95%, accounting for 49.06% of the entire battery industry. (Lithium - Ion Battery Equipme

Today, the National Automobile Standardization Committee announced on its official website the draft for comments on the recommended national standard for automobiles, "Specifications and Dimensions of Power Battery Products for Electric Vehicles", which was organized and revised by the Electric Vehicle Sub-Standard Committee. According to the draft, under the condition that the industry specifications for automotive power batteries are gradually being improved, the specifications and size standards fo

At the 2016 my country International Graphene Innovation Conference held recently, Tunghsu Optoelectronics (stock code: 000413) recently announced the power bank product "ene king" is still the focus of attention. Wang Zhonghui, deputy general manager of Tunghsu Optoelectronics, emphasized: "'The King of Graphene' is not a graphene battery, but a graphene-based lithium-ion battery. We have never said that it is a graphene battery in our previous publicity." Since the announcement of &

New energy vehicles are one of my country's strategic emerging industries and occupy an important position in "Made in my country 2025". The hollowing out of the core technology of traditional fuel vehicles has always been a pain in the heart of my country's auto industry. The battery is the "gathering place" of the core technology of new energy vehicles. Recently, the author heard that several major domestic auto companies are in contact with battery companies such as Samsung SDI, LG
