It is understood that "Changwei" battery is a colloidal power battery with low calcium alloy internalization and long life. It completely subverts the design concept of traditional lead-acid batteries in structural design and adopts a number of independent patented technologies for precision manufacturing. The battery has a unique structure, which can ensure zero leakage of the battery terminal, and it is not easy to crack the battery shell during installation and use, completely eliminating the corrosion and open circuit problems of the internal connecting devices of the battery, and the consistency of the battery has been improved unprecedentedly. At the same time, under the condition of keeping the external volume of the battery unchanged, the size and specific surface area of the electrode were optimized again, and the battery capacity was improved by about 5%. In order to further improve the service life of the battery, the company's R&D personnel also used special additives to slow down the corrosion rate of the electrode by changing the density of the electrolyte, which prolonged the service life by more than 20% compared with ordinary batteries. In addition, the battery also adopts the design of safety valve, which is more safe than ordinary batteries, and can ensure that the shell will not burst during use and eliminate potential safety hazards.
"Changwei" battery has the advantages of novel structure, large capacity, long life and good safety, which is a technical breakthrough. The battery is mainly used in the high-end electric moped market to promote the brand integration of the domestic high-end electric moped market. In recent years, with the intensification of competition in the domestic electric moped market, the lead-acid power battery, as the core component of electric vehicles, has been unable to meet the market demand of high-end brand electric vehicle manufacturers and first-line dealers due to the increasingly serious homogenization phenomenon. In this regard, after market research, Wei Chao Group put forward the R&D strategy of "eliminating homogeneity and seeking differentiation". According to this requirement, the company introduced the latest technology of Fuzhou University-German international high-energy battery technology in time, and the technical department and Fuzhou University jointly undertook the research and development task of "Changwei" brand battery. After more than three years of technical research, Changwei battery was finally put into mass production at 20 12.
The appearance of Wei Chao Power "Changwei" brand power battery has attracted the attention of many well-known domestic electric moped manufacturers and first-line dealers. It is understood that the battery has been used with some high-end brands of electric mopeds in China, and the market response is good, which has accelerated the process of brand integration marketing in the electric vehicle market. An industry expert said that the smooth production of "Changwei" means that the battery technology has been upgraded again, which has also injected new energy into the industry and brought another new leap to the whole industry.
