Introduces a lithium-ion battery in the application of the electric bicycle industry

Source: 2020 - 04 - 06 12:03 hits: lithium ion battery in the application of lithium ion battery electric bicycle industry in our country, the application of electric bicycle industry has experienced three stages: 1. From 2000 to 2004, power lithium battery safety problem has not been solved. Some of China's electric bicycle companies bold attempt to use lithium cobalt acid lithium ion batteries. Ii. From 2005 to 2008, represented by suzhou heng heng manganese acid lithium batteries, lithium battery enterprise promoted strongly, has solved the manganese acid lithium battery safety, start mass production and market. Iii. Since 2009, the quality of the lithium battery has the very big enhancement. It has reached the practical stage. From 2007 lithium-ion battery electric bicycle on the batch application, it has been seven years, specializing in the production of lithium battery electric bicycle enterprises, such as suzhou jie than Mr Lu and JieXiang, beautiful line in tianjin, ningbo, shenzhen HuaTa has made a significant contribution to the enterprise, and the original manufacturer of lead acid battery electric bicycle once encountered problems, and tend to give up the lithium battery electric bicycle, turning lead-acid electric cars. At present, the more mature lithium electric vehicle production enterprises, export sales accounted for more than 60%, domestic sales of less than 40%, with exports and domestic sales. In power lithium battery export quantity, the five main components of the lithium-ion batteries ( Motors, lithium battery, charger, controller, sensors) Components for exports is greater than the vehicle exports, exports accounted for about 60% of the whole vehicle exports. At present, the application of lithium ion batteries in electric bicycle slowly. This is because: 1. The performance of lithium battery needs to be improved. Hope that the life expectancy of lithium-ion batteries in 3 years, 2 years of repair rate less than 2%, and on the ratio of more than lead-acid batteries. 2. Industry result in low price disorderly competition in the market is filled with bad products, quality accident frequency, affected the enterprise's ability to improve the quality and enthusiasm, led to the slow development of lithium-ion battery technology. 3. Lithium battery after-sales service is not standard, complex operation, brings anxiety to vendors and users, has affected the lithium battery electric bicycle sales. 4. Promote the lithium battery electric bicycle is the key to the government did not applied to the new energy, promote the lithium battery policy guidance and the limitation of the lead-acid battery, lithium batteries used in electric bicycle should give policy preferences, and cause environmental pollution of lead acid batteries should limit policy. Policy guidance affect the application of lithium battery electric bicycle.
