On January 14, 2014, at the special forum on the status and development of power batteries for the "China Electric Vehicles 100", Zhang Xiangmu, director of the Equipment Industry Department of the Ministry of Industry and Information Technology, pointed out how far new energy vehicles can go, ultimately depending on Power battery, "It can be said that whoever masters the key core technology of the power battery, whoever has the initiative to develop new energy vehicles."
In order to promote the development of power batteries, Zhang Xiangmu pointed out that the work required in China is to promote technological progress. The production of power batteries in China is not the most. At present, it is necessary to develop and improve relatively mature lithium-ion batteries, and to strengthen the deployment of new battery systems. . At present, China's single battery has made great progress, but after the battery pack is made, the performance will be greatly reduced. Moreover, there is still a big gap between China and the international level in battery control, storage technology and system integration.
As China's lithium-ion power battery enterprises are generally small and scattered, and most of the production capacity is not up to standard, Zhang Xiangmu reiterated that he should adhere to the "standard conditions for automotive power battery industry", thereby strengthening the supervision of automotive power battery products, preventing low-level redundant construction and promoting power batteries. Technological progress and scale development of production enterprises.
2014 is regarded as the first year of the development of new energy vehicles. From the data point of view, the development of new energy vehicles has become a trend. Between 2009 and 2012, China produced more than 10,000 new energy vehicles and produced more than 20,000 vehicles in 2013. In 2014, it grew to more than 80,000 units, of which 27,000 were produced in December.
From October 28 to November 28, 2014, the Ministry of Industry and Information Technology publicly collected opinions on the “Regulations on the Standards of Automotive Power Battery Industryâ€. The specification clarifies the basic requirements of the power battery enterprise, production conditions, technical capability requirements, product requirements, quality assurance capability requirements, sales and after-sales service conditions. Among them, in the basic requirements of enterprises, the requirements of the standard conditions for the production capacity of the enterprise are worthy of attention. The annual production capacity of the system production enterprises is not less than 10,000 sets or 200 million watt-hours.
Mounted units are two part assemblies: The housing and the bearing insert. There are several housing options that are considered [stock" housings; these are very common in the power transmission industry. Mounted unit inserts come in a variety of styles. The most common are radial ball Bearing Inserts, tapered roller bearing inserts, spherical roller bearing inserts, and plain bearing inserts. Bayview bearing & Supply stocks all common sizes in our Egg Harbor City warehouse.
Ball Bearing Mounted Units – Ball bearing mounted units are the most common unit in the industrial market. Ball bearing mounted units utilize a ball bearing insert and can be purchased as greaseable or sealed for life.
Tapered Roller Bearing Mounted Units – Tapered roller bearing mounted units, or Type E bearings, are a mounted unit that utilizes a tapered roller bearing cartridge insert. Type E bearings offer a higher load and speed ratings than ball Bearing Units .
Spherical Roller Bearing Mounted Units - Spherical roller bearing mounted units is another type of housed bearing. Spherical roller units offer the highest load ratings available and can adjust to misalignment.
Plain Bearing Units- Plain bearing units are the original mounted units. Plain Bearings can be made of 660 Bronze, wood, or lead. These units have high load and temperature ratings, but cannot run at a high RPM.
