To say the prospect of the lithium battery wholesale market of the new national standard electric bicycle, I have to ask why it is necessary to promote the electric bicycle on a large scale because the car is so convenient now? Automobile not only promotes economic prosperity and brings convenience to life, but also brings energy and environmental protection problems. Automobile exhaust has a great impact on the environment. With the rapid growth of the total number of motor vehicles, automobile exhaust pollution is becoming more and more serious. In big cities such as Beijing, Shanghai and Guangzhou, motor vehicles have become the largest source of carbon monoxide, nitrogen oxides, hydrocarbons and other pollutants. After years of market development, people's awareness of environmental protection has been strengthened, and the concept of green travel has been deeply rooted in the hearts of the people. Electric bicycles have gradually become an important means of transportation for consumers' daily short-distance travel. Now, with the introduction of the "new national standard" of electric bicycles and the impact of environmental protection policies, the market share of lead-acid batteries for old electric bicycles will slowly shrink, while the market share and Prospect of lithium batteries for portable electric bicycles are very large.
The application advantage of lithium battery in the electric bicycle industry is that lithium battery is a new green high-energy chemical power supply, because lithium-ion power battery has the following advantages: high working voltage; Higher specific energy; Small volume; Light weight; The cycle life is 2-3 times longer than that of lead-acid battery; Low self discharge rate; No memory effect; Environmental protection, etc. It shows very superior performance in the application of high-energy and high-power electric bicycle power supply, electronic equipment and electric toys. When the medium discharge current is above, the discharge time of lithium battery can be several times that of lead-acid battery; At present, the development of lithium-ion battery is still in a bottleneck period: safety performance and power battery management system. In terms of safety performance, users put forward very high requirements for the safety of lithium battery due to its high energy density, high working temperature and poor working environment.
At present, in order to meet the requirements of the "new national standard", the industry mainly has the following three ways: first, R & D and production of lightweight lead-acid batteries. However, the production technology and production line of lead-acid batteries are relatively mature, and it is not easy to realize the requirements of the "new national standard" in a short time; The second is to produce lightweight body. For the car factory, this step is relatively easy to control, but since the previous weight of electric bicycles was mainly concentrated on the battery, it is difficult to meet the standard only by reducing the body weight; Third, replace the original lead-acid battery with lithium battery. For the current electric bicycle enterprises, the development of the upstream and downstream industrial chain has been very mature, and it is not easy to directly and widely replace suppliers. However, with the continuous improvement of consumers' brand awareness in the future, the industry will usually adopt the method of the first plus the second to make the transition first. It is a trend for lithium batteries to further replace lead-acid batteries in electric bicycles. The prospect of the new national standard electric bicycle lithium battery wholesale market is very broad.
