"Add power station" to crack electric car charging difficulty

Going out to the car is closely related to the lives of the people, the electromagnetism of the car is the future development trend, in line with the National energy conservation and emission reduction policy call, new energy and electric vehicles have received more and more extensive attention from all walks of life. However, the difficulty of charging has become one of the main reasons that restrict the development of electric vehicles, causing the construction of electric vehicle charging facilities to be in a dilemma. In view of the backward charging pile technology, difficulty in operation management and high construction cost, flexible matrix charging reactor technology has emerged, which provides an innovative model for the future development of electric vehicle industry.

Charging pile construction is in a dilemma

According to the "Guidelines for the Development of Electric Vehicle Charging Infrastructure (2015-2020)" issued by the National Development and Reform Commission and other departments, it is clearly stated that by 2020, the number of electric vehicles will reach 5 million, and the number of new centralized charging and replacement stations in the country will exceed 12,000. More than 4.8 million decentralized charging piles are available to meet the charging needs of 5 million electric vehicles nationwide.

Electric cars are energy-saving and environmentally friendly, but charging is a bit difficult. The biggest concern for car owners when buying and driving electric vehicles is the difficulty of charging: charging pile parking spaces are occupied by fuel trucks, charging long lines have to pay parking fees, and charging requires a high parking fee of 10 hours is even more painful. Different charging platforms can not be used. Car piles do not match the charge of electricity and so on .... all these things are not satisfactory, most electric car owners have encountered.

On the one hand is the large-scale planning and construction, on the other side is the extremely low utilization rate of charging piles, the owner's charging is inconvenient, which is the current dilemma facing the layout construction of charging piles in China. Statistics from the national power grid show that at this stage, the daily charge time of a single charge pile operated by the national power grid is 0.35 hours, and the overall utilization rate is 1.46 %. Statistics from the southern grid show that as of January this year, the southern grid system has built a total of 4356 charging piles, most of which are vacant.

Three major reasons for poor charging

Backward charging pile technology, difficulty in operation and management and high construction cost are the main reasons for the difficulty in charging electric vehicles.

First, the development and construction of charging piles often can not keep pace with the "upgrade" of electric car batteries. With the increase in the range of electric vehicles and the development of rapid charging technology, the battery recharging rate has continued to increase. A considerable part of the charge piles are due to the slow charging and have been abandoned by the owner after just one or two years of construction and have been vacant for a long time.

Pile vehicle mismatch is also an important reason for the difficulty of charging. Due to the inconsistent charging standards in the pre-electric vehicle industry, the capacity and charging ratio of various types of electric vehicles in China are different, and the output power requirements of charging Motors vary greatly. In order to meet the charging needs of various types of electric vehicles, the output power of charging piles is designed to be very large, which will cause waste of energy when charging electric vehicles with small energy storage capacity; However, if the output power of the charging pile is designed to be small, charging the electric car with a large storage capacity will lead to a long charging time, which will cause inconvenience to the owner.

Secondly, the operation and maintenance of decentralized charge pile is very difficult. Due to excessive dispersion, it is difficult to manage the on-site operation. The phenomenon of "occupying" the charge pile position of the fuel truck is extremely common. Electric car owners often find the charge pile and can only "hope Mei to quench thirst"; On the other hand, due to difficulties in maintenance, the failure rate of charging piles is extremely high, and phenomena such as vehicles not charging on charging piles, abnormal current, and charging guns not pulling down occur from time to time.

Third, the main areas of charging piles include shopping districts, office buildings and parking lots. The area is expensive, the construction cost is high, the owner's parking fee is expensive when charging, and the construction and use costs are high.

"Add Power Station" Solving Problem

With the rapid development of power battery technology, the demand for intelligent and convenient charging system will be higher and higher in the future. If the difficulties facing charging facilities can not be solved, the development of electric vehicle industry will be greatly limited.

According to media reports, the flexible matrix charging reactor technology developed by Shenzhen Otis Power Equipment Co., Ltd. with independent intellectual property rights is committed to improving the status quo. This technology can integrate all or part of the intelligent charging modules and monitoring systems in the electric vehicle charging station, and use computer control technology to centrally control and dynamically distribute the intelligent charging modules to provide electric power cells for electric vehicles. This technology is expected to increase the utilization rate of charged piles and reduce large amounts of waste.

Recently, Xiao Xia, member of the 3rd China DC Standards Committee and chairman of Autoxun, told the media that the flexible matrix charging reactor has the following characteristics compared with the traditional charging pile. First of all, the flexible matrix charging reactor technology can automatically identify and allocate the required maximum charging power according to the charging demand of the vehicle, ensuring that each electric vehicle can be charged at the maximum power, which satisfies the future "battery upgrade" requirements of electric vehicles, to avoid the repeated construction of charging pile facilities.

Secondly, the operation difficulty of the centralized flexible matrix charging stack is greatly reduced compared to the decentralized charging pile. Flexible matrix charging reactor technology uses a charging cabinet, which can also meet the power supply of more than 10 charging piles, arrange special personnel for on-site maintenance management, and build an electric vehicle "power station" similar to a fuel truck gas station. This can prevent fuel cars from occupying charging piles and timely troubleshooting.

Third, the construction of a centralized flexible matrix charging reactor can form a chain of benefits for power grids, operators and landowners. This business model can reduce the construction cost, improve the utilization rate of charging piles, avoid waste, and increase the enthusiasm of all parties.
