With the development of China's urbanization process, the electric bicycle industry has experienced rapid development for many years, and will soon usher in the most stringent new national standard on April 15. When consumers buy electric bicycle products, the primary consideration is the cruising range. The new national standard will lead to a new era of polymer lithium-ion battery electric bicycles.
　　 Lead-acid batteries have long dominated the market with low prices, but lead-acid batteries have inherent shortcomings such as short service life and heavy weight. In order to meet the consumer's requirements for battery life, traditional manufacturers can only use more and more cumbersome lead-acid batteries to solve the problem. Under the new national standard requirements, this solution seems to be no longer feasible. The new national standard has changed the parameters of electric bicycles. Among them, the upper limit of 55kg is set for the whole vehicle quality, and at the same time the battery weight must be reduced; then, the lighter weight polymer lithium ion battery is the only alternative to the lead acid battery.
　　 Compared with traditional lead-acid batteries, polymer lithium-ion batteries give people the most intuitive feeling of smaller size and lighter weight. In general, the same volume of polymer lithium-ion battery is 2 to 3 times the capacity of lead-acid batteries; in addition, polymer lithium-ion batteries have a service life of up to 5 years, while lead-acid batteries have only 2 to 3 years. Polymer lithium-ion batteries are more cost-effective than lead-acid batteries.
　　 The more fashionable and more decent electric vehicle products are born on the basis of polymer lithium-ion batteries, and the polymer lithium-ion battery electric vehicles are more designed. At the same time, most battery intelligent management systems (BMS) are also based on polymer lithium-ion batteries, which adds a safety guarantee for vehicle use.
　　 Although the market share of electric vehicles today is still far below the share of lead-acid battery models, lithium-ion products account for less than 20% of the total market. After the new national standard, electric bicycles will enter a new track, and each enterprise will compete in the intelligent technology of lithium battery and lithium battery. After the traditional big factory loses its inherent advantages, the emerging enterprises have the advantage of relying on the advantages of lithium battery. The advantages of lithium battery are obvious, and the replacement of lead-acid batteries is a trend of social progress. Do you like this electric car?
