Following the fatal traffic accident of Uber's self-driving test vehicle due to the failure of its self-driving system, a Tesla Model X in California, United States, exploded after a traffic accident. The owner of the car died of his injuries after being taken to the hospital. Insiders told reporters that Tesla's good-looking data on performance and mileage can be said to be achieved on the premise of radical technology. He said that during the use of Tesla's 18650 battery, as long as there is a slig

Lithium-ion batteries are simply lithium-ion batteries, which have been widely used in some models of electric vehicles. For the first charging of lithium-ion batteries, the charging time and methods of lithium-ion batteries, the global electric network editor Yu Jiangping will be below. Explain in detail to everyone. Correct use of lithium-ion electric vehicle batteries The correct use of lithium batteries actually boils down to three points. The editor of Global Electric Vehicle Network has summarized the f

Soft case Li-ion batteries are 40% and 20% lighter than steel and aluminum case Li-ion batteries. In terms of weight, soft-loaded lithium-ion batteries are much lighter than hard-loaded lithium-ion batteries, but the important weight ratio still depends on the weight of the box. different abilities Soft-pack lithium-ion batteries are 10% to 15% higher than steel and aluminum batteries, and 5% to 10% higher than steel and aluminum batteries. Although the capacity of soft-pack lithium-ion batteries is not much

As a core component of digital products and electric vehicles. Lithium-ion batteries in these products typically consist of multiple cells. During use, charge and discharge performance and battery life may be significantly reduced due to increased internal core temperature of the battery cells. Especially for power lithium batteries in the automotive field, accurate cell temperature estimation and monitoring are critical to the performance and life of the entire battery system.(Lithium - Ion Battery Equipment)

In 2018, Guoxuan Hi-Tech invested 493 million yuan in research and development. The research and development projects include: 22-platform lithium iron phosphate battery development, ternary battery development and industrialization, battery capacity design and manufacturing assurance technology, model-based battery design and There are 6 major projects including intelligent manufacturing technology development, technology to improve battery energy density, and 20 platform lithium iron phosphate battery development

Is hydrogen fuel-powered lithium battery a real black technology? Recently, BYD revealed to investors that it is developing hydrogen fuel-powered lithium batteries. In fact, in May, BYD struck a deal with an American company, Hybrid Electric Power, to collaborate on hydrogen fuel-powered lithium-ion battery buses. Not only BYD, it is understood that domestic companies Weichai Power and Great Wall Motors have successively deployed hydrogen fuel-powered lithium batteries. Japan's Toyota began research on hy

In recent years, the development of new energy vehicles has developed by leaps and bounds, and there is a tendency for latecomers to catch up. In the research and development process of new energy vehicles, whether it is the extended-range hybrid model Volt launched as early as 2010, or planned in 2023 Before the vision of launching at least 20 pure electric vehicles, GM has already placed new energy vehicles at the height of corporate strategic development. Whether it is a pure electric vehicle or a hybrid vehi

The primary problem of BMS is security, which needs to have: 1) Overcharge protection, that is, the charging needs to be terminated in time when the voltage exceeds the standard. 2) Over-discharge protection, that is, the discharge is terminated when the voltage of any cell in the group is lower than the over-discharge threshold. 3) Over-current and short-circuit protection, the main function is that the output can be automatically turned off and enter the self-locking state when excessive discharge curren

Lithium battery has entered people's daily life on a large scale, but where does it come from? What are the links in the production process of lithium batteries? Although there are some differences in the production process of lithium batteries depending on different lithium battery manufacturers, due to the same principle, the main production processes of lithium batteries are basically the same, generally including: batching, coating, rolling, cutting, slitting , Welding tabs, winding, packaging, baking, liqu
