Why aren't lithium-ion electric cars popular?

According to relevant research reports, the China electric bicycle association released the data of electric bicycles in China from 2014 to 2016: among them, lithium electric bicycles account for less than 3 million, accounting for less than 10%, and occupy a very low share in the whole electric bicycle. There are many reasons for this. One is the safety of lithium battery. Through the influence of lithium battery explosion in the past, people have doubts about the safety of lithium battery. Secondly, as for the price, lithium battery electric vehicle half (the range of larger higher); Thirdly, as for practicality, people have many tools for short distance travel, such as sharing bicycles. As a result of these three fundamental reasons, lithium battery electric bicycle, want to improve the market share, must solve these problems, find the direction of development.

In the retail market, there are few exclusive stores for lithium electric bicycles, and even big cities like Beijing, Shanghai, Guangzhou and Shenzhen do not exist. At best, in some large-scale electric vehicle physical stores, lithium electric bicycles are placed in the corner, rather than become the focus of sales. In this Tianjin bicycle exhibition, in addition to the new day launched several lithium electric bicycle products, even Emma, Luyuan, tailing and other large-scale enterprises can hardly see the shadow of lithium electric bicycle; Likewise, companies that specialize in bicycles are almost retreating from making lithium-ion bikes. This shows that lithium electric bicycles in the current domestic market have not become the mainstream. So what are the reasons for the slow spread of lithium electric bicycles over the years?

Lithium - electric bicycles can only be marketed locally. For example, in Beijing, nanjing, jinan and other markets, lithium electric bicycles account for a relatively high proportion of sales, especially in Beijing market, nearly two years of sales accounted for more than 30%. The rise in sales of lithium-ion bikes in Beijing has been driven mainly by congestion on the city's roads and government support for their use. In contrast, in Shanghai, lithium electric bicycles account for only 3-5% of sales in the past two years.

Sales in Guangdong's cities are around 6%. In smaller cities, li-ion bikes are less popular, and rural markets are even rarer, barely visible. The biggest problem restricting the promotion of lithium electric bicycle is the maintenance. If it is in Beijing, it will be very convenient to repair. Businesses will replace the batteries with problems, temporarily replace the old batteries for consumers, and wait until 10 days or so before they go to the store to replace the original repaired batteries. This kind of treatment is not available in every region, which restricts the sales of lithium electric bicycles.

The lithium - electric bicycle is too delicate to be anything but a walking tool. After the heavy load of lithium electric cars, there will be a lot of problems, such as short mileage, short service life, etc., if the charger quality is not good, lithium battery protection plate has problems, will occur in the charging process of fire and other problems, which makes consumers feel a little afraid.

The quality of lithium battery itself still needs to be improved. Different from lead-acid batteries, lithium batteries pay great attention to the consistency and stability of batteries in the assembly of cells. For example, 18650 batteries are used. In series and parallel connection, the voltage of each cell should be absolutely consistent. If the cell voltage is not consistent, the short plate effect will appear. Many vehicle companies in order to reduce costs, often in the choice of charger manipulation; Those small lithium battery enterprises will also be in the protection plate, battery cell on the movement of anencephaly, the result is obviously, lithium battery did not use to the provisions of the warranty period, lithium battery capacity has been unable to guarantee the continuation of the mileage of lithium electric bicycle.

According to the introduction, at present domestic electric vehicle lithium battery repair rate of the highest can reach about 13%, the lowest also in about 5%. Now many electric bicycle lithium battery enterprises are basically operating at the profit and loss point, battery enterprises almost no net profit, the reason is the serious excess capacity, large scale enterprises play price war to the death.

Although the lithium electric bicycle prospect development is very good, but the lithium electric bicycle quality does not go up, lithium electric bicycle after-sales service and lead acid battery cannot be replaced and maintained as convenient, may enter the bottleneck period of development.
