Like the current coexistence of a large number of cars with different displacement, as more and more electric vehicles and spending power of different groups, the future will appear small and medium power charging power coexistence.This gives the government planning charging facilities out A major problem: how to layout the geographical space? How to distribute the charging power? 'On January 19 at the 2018 annual working meeting of China Charging Federation, China's leading electric vehicle charging facilities, chairman of Shenzhen Ott Xun Power Equipment Co., Ltd. Xiaoxia throw the above problem.
In Xiao Xia's opinion, the current development of electric vehicle charging facilities faces a serious bottleneck: structural supply imbalances.According to China Recharge Alliance estimates, the number of new energy vehicles in China is about 1,729,000, of which the number of pure electric vehicles is close to 1.5 million , Pure electric passenger car ownership 801000. According to this data, pure electric passenger car pile ratio has reached 1.8: 1.
In spite of this, there still exist a large number of charging power mismatch problems.High-power electric vehicles are difficult to find the power matching charging pile, charging efficiency is low; low-power cars sometimes charging in high-power charging pile, power waste.Moreover, some places Of the charging facilities in short supply, electric vehicles long lines charge; some local charging facilities and oversupply, resulting in very low utilization. 'Xiao Xia said.
Xiao Xia believes that the most important thing is the construction of electric vehicle charging facilities need forward-looking overall planning, but this plan is difficult to do, mainly due to the rapid changes in battery technology.Although we all agree that high-power charging is the future of the mainstream trend, but In addition, limited by the cost of the battery and the final transmission to the consumer sales price, the future will inevitably occur Dazhong Xiao electric vehicles coexist, because the low-cost low-cost, high-power prices High; and this ratio will have a major impact on the planning, the same unpredictable.
In the exchange with many local governments, Xiao Xia also found that the problem became more and more obvious. "Some places made overall planning and found that they were embarrassed by the upgrade of battery technology before the return on investment in charging facilities Situation: It is not willing to demolish and rebuild it. If it continues to be used, it will not satisfy most needs.
'A few years ago, Ott Xun foreseen this pain point, and the organization independently developed the matrix-type flexible charging stack technology.' Xiao Xia said, 'All or part of the smart car charging station charging module integrated together, according to vehicle demand Automatic distribution of charging power, breaking the existing charging infrastructure power curing problems, a substantial increase in charging power and equipment utilization, so that the city charging infrastructure planning and construction.
Xiao Xia further elaborated that a standard reactor with an installed power of 1080KW can now meet the charging needs of 1,000 social passenger cars, and either terminal can output power of 15kW to 180kW to dynamically match the connected electric vehicles The required charging power can not only meet the current situation of long-term co-existence of large and small charging power, but also adapt to the development of high-power charging technology in the future so that the scientific, rational and orderly planning of city charging facilities is feasible.
'A planning point, you can build a pile, to meet the basic needs of the nearby charge. If one day found that charging at this point to start lining up, it is very simple, and then stack a pile can be. The past heap can be the same Continue to use and so on, until the region's charge to achieve a balance between supply and demand .Xia Xia told reporters that in the future, whether it is to upgrade the battery life mileage or charging rate to bring the charging power increase, simply increase in each charging station The number of charging heaps, while the same land area requirements, will be able to adapt to the development of high-power charging technology.
'The application of this technology is a good solution from the point of view of difficulty in charging new energy vehicle owners, making equipment operators profitable and difficult for government planning.' Xiao Xia said that with the current long-term coexistence of different power vehicles and the future The development trend of high-power charging technology, charging pile technology innovation, and truly compatible with the current design concept of the future of the economy will completely solve the social charging problems.
'At present, we have built nearly 100 compact and flexible public charging stations in Shenzhen, which can meet the charging needs of 100,000 passenger cars.' Xiao Xia said that each intensive flexible public charging station occupies 20 parking spaces Bit or 1000 square meters of land by the N standard charging stack unit, the number of each charging station service vehicles can achieve accurate calculations, according to the social charging needs of scientific, rational and orderly layout, so that charging stations like gas stations The same distribution in every corner of the city.
According to the plan, the end of 2018, Autodesx will also build 300 intensive flexible public charging stations in Shenzhen to meet the 300,000 electric passenger car charging needs, initially set up a regional public charging network, so that owners have and gas stations The same convenient charging experience.
'The development of new energy electric vehicles is inseparable from the city's charging infrastructure. We are very proud to have Otex, a technology that has helped us to realize the rapid development of new energy electric vehicles through technological iterations.' ' Xia said.
In 2015, the General Office of the State Council promulgated the Guiding Opinion on Accelerating the Construction of Charging Infrastructure for Electric Vehicles, which mentioned that by 2020, an infrastructure infrastructure that is modestly advanced, with pile-driving and intelligent and efficient charging infrastructure will basically be built up, Charging needs of 5 million electric vehicles. "In response to this, Xiaoxia made an initiative to promote the planning of the relevant departments in the process, should consider the technological advances brought about by the advanced nature of charging services, make appropriate adjustments to the planning program, We will actively embrace new technologies in order to build our country into a world-class charging network for electric vehicles faster and with higher quality so as to accelerate the universal use of new energy vehicles.
