Electric Bicycle Charging Station

An intelligent charging and charging device which can quickly charge and conveniently set up in cities, has been successfully developed by the Institute of environmental protection and energy technology, Changshu, Jiangsu, and has been demonstrated in Changshu area.

According to the Changsha Yongxin, the device consists of five parts: fast charging batteries, fast charging chargers, intelligent IC card charging system, charging devices installed on the roadside and supporting cables, plugs and sockets.

The most fast charging battery and fast charger in the system have applied for national invention patent.

The price of the whole system is around 3000 yuan.

The traditional charging method of the battery is filled with batteries. Each battery needs to be filled. Otherwise, it will cause the battery capacity to drop and affect the service life. The system uses a special structural battery. It can make the battery charge from 20% (less than 20% of the battery charge) to 70% in 8-10 minutes by using a special charger, which is sufficient for users to continue cycling for 20-30 kilometers.

The rest of the bike can go home and take the slow charging method to fill the battery.

Over the past few years, electric bicycles have become more and more popular in China. Especially in economically developed areas such as Jiangsu and Zhejiang and the Pearl River Delta, electric bicycles are gradually replacing the traditional means of pportation because of the restrictions on the development of motorcycles and fuel powered vehicles.

However, with the popularization of applications, the disadvantages of electric bicycles using traditional lead-acid batteries are becoming more and more obvious: short service life, long charging time, and gradual increase of battery mileage with the increasing use time. Many people are running out of batteries and have to push home.

How can we solve this problem?

Now many manufacturers have begun to pay attention to this problem. The measures adopted are the use of rechargeable batteries with larger capacity and higher mileage, such as Ni MH batteries, and even more advanced lithium battery products. However, such batteries are expensive and have long charging time.

It is hoped that electric bicycles can also be fast charging on the half way, just like ordinary cars and motorcycles.

It is understood that the business operation mode of the institute adopts the form of franchising and franchise, and director Sha Yongxin introduces that they plan to absorb a chain franchisee in every city to build a unified charging station network.

The Institute provides the necessary equipment and technical services for the station, and the franchisee is responsible for the network layout of the charging station, the sale of special batteries and after sales service.

The scale of 300 charging stations in a city is calculated. The total investment is 1 million yuan.

Unlike the gas station, the proportion of electricity charges in the operating cost of the charging station is very low. Generally speaking, it takes about 0.45 degrees to fill a standard battery. Only 70% degrees of electricity cost 0.3 degrees, and the cost is about 0.15. According to the charge of 1 yuan, electricity accounts for only 15% of the total cost.

This charging station has lower power demand. According to Sha Yongxin, the power of the charging station is between 1.2-1.5KW, which can directly use the civil power grid for power supply.

Each charging station is charged 30 times a day, charging 1 yuan for each charge, excluding all kinds of operating costs, the daily profit is around 20 yuan. According to the 360 day business time of a year, the annual profit can reach 7200 yuan, that is to say, the cost can be recovered within six months.

The risk indicates that the charging station is an ancillary industry of electric bicycles. Its development depends on the size and possession of a city. Besides, the urban traffic control department is also a potential risk factor for electric bicycles.

Take Beijing as an example, at present, Beijing has no license for electric bicycles, and even a licensed vehicle can only ride to 2006. Therefore, when considering the project, we must examine the local traffic policies and regulations in detail.

In addition, reporters in the interview feel that the concept of electric bicycle charging station is undoubtedly advanced, the cost of a single charging station is not high, only about 3000 yuan, but if we consider that the overall layout of a network in a city has a long cycle and a big investment disadvantage.

In particular, the cost of IC card charging system is too high. It is worth considering whether it is necessary for some small cities to adopt IC card charging system.

Reporters believe that the best way is not to do not take the form of franchise, but to purchase a single device as required, placed in roadside shops, repair shops and other places, charging time charge.

The need for special attention is that the fast charging station needs to use the new battery developed to achieve the best performance. Sha Yongxin introduced that the battery price is 100-200 yuan higher than that of the ordinary battery, but the performance has also been greatly improved. The charging capacity is increased by 20% compared with the ordinary battery, and the life is increased by 50%.

Generally speaking, electric bicycle users need to replace new batteries every 1-2 years. Therefore, when a city builds its station for the first time, it should consider the problem of changing new batteries, which may prolong the cycle of return.
